Management of potentially inappropriate medication use among older adult's patients in primary care settings: description of an interventional prospective non-randomized study. BMC PRIMARY CARE 2024; 25:213. [PMID: 38872125 PMCID: PMC11170768 DOI: 10.1186/s12875-024-02334-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Accepted: 03/07/2024] [Indexed: 06/15/2024]
Abstract
BACKGROUND The management of inappropriate medication use in older patients suffering from multimorbidity and polymedication is a major healthcare challenge. In a primary care setting, a medication review is an effective tool through which a pharmacist can collaborate with a practitioner to detect inappropriate drug use. AIM This project described the implementation of a systematic process for the management of potentially inappropriate medication use among Lebanese older adults. Its aim was to involve pharmacists in geriatric care and to suggest treatment optimization through the analysis of prescriptions using explicit and implicit criteria. METHOD This study evaluated the medications of patients over 65 years taking a minimum of five chronic medications a day in different regions of Lebanon. Descriptive statistics for all the included variables using mean and standard deviation (Mean (SD)) for continuous variables and frequency and percentage (n, (%)) for multinomial variables were then performed. RESULTS A total of 850 patients (50.7% women, 28.6% frail, 75.7 (8.01) mean age (SD)) were included in this study. The mean number of drugs per prescription was 7.10 (2.45). Roughly 88% of patients (n = 748) had at least one potentially inappropriate drug prescription: 66.4% and 64.4% of the patients had at least 1 drug with an unfavorable benefit-to-risk ratio according to Beers and EU(7)-PIM respectively. Nearly 50.4% of patients took at least one medication with no indication. The pharmacists recommended discontinuing medication for 76.5% of the cases of drug related problems. 26.6% of the overall proposed interventions were implemented. DISCUSSION The rate of potentially inappropriate drug prescribing (PIDP) (88%) was higher than the rates previously reported in Europe, US, and Canada. It was also higher than studies conducted in Lebanon where it varied from 22.4 to 80% depending on the explicit criteria used, the settings, and the medical conditions of the patients. We used both implicit and explicit criteria with five different lists to improve the detection of all types of inappropriate medication use since Lebanon obtains drugs from many different sources. Another potential source for variation is the lack of a standardized process for the assessment of outpatient medication use in the elderly. CONCLUSION The prevalence PIDP detected in the sample was higher than the percentages reported in previous literature. Systematic review of prescriptions has the capacity to identify and resolve pharmaceutical care issues thus improving geriatric care.

Abstract
Helicobacter pylori is the main etiopathogenetic factor of chronic gastritis, peptic ulcer disease and gastric cancer. The world's population is shifting towards older people, who have the highest prevalence of H. pylori. Aging-related peculiarities could have an impact on the treatment of H. pylori and there is still a lack of research data in the older population. The aim of this review was to summarize the findings of the most recent information, publications and studies on the issues relating to H. pylori infection in older patients. H. pylori eradication offers gastrointestinal and extra gastrointestinal benefits in older patients. Based on the main guidelines, H. pylori should be eradicated independent of the patient's age, only reconsidering cases with terminal illness and low life expectancy. Proton pump inhibitors are generally safe and well tolerated. Some antibiotics require dose adjustment only in advanced renal insufficiency and the risk of hepatotoxicity is very low. Special precautions should be taken in patients with polypharmacy and those taking aspirin or non-steroidal anti-inflammatory drugs. In older patients, H. pylori eradication treatment frequently causes only mild and short-term adverse events; however, treatment compliance is usually still very good. H. pylori treatment in older patients does not increase the risk of Clostridium difficile infection. Optimal eradication effectiveness (> 90%) is mostly achieved with bismuth- and non-bismuth-based quadruple therapies. Susceptibility-guided treatment of H. pylori can contribute to increasing the effectiveness of eradication regimens in older adults. To achieve optimal H. pylori eradication effectiveness in older patients, the same guidelines, which are applied to adults, also apply to this population: avoiding repetitive treatment prescriptions, choosing quadruple therapies, prescribing longer treatment duration and administering high-dose proton pump inhibitors twice daily.

Abstract
PURPOSE Acid suppressive therapy using histamine H2 receptor antagonists (H2RAs) and proton pump inhibitors (PPIs) can be utilized for the prevention of gastrointestinal bleeding (GIB) among patients with cardiovascular disease receiving dual antiplatelet therapy (DAPT). However, emerging data suggests underlying associations between PPI or H2RA use and cardiovascular disease incidence, progression, and mortality. This review explores the history of acid suppressive therapies and their use in cardiovascular disease patients and the growing evidence in support of H2RA use. RECENT FINDINGS PPIs were originally championed as better than H2RAs for preventing GIB events in cardiovascular disease patients on DAPT therapy, but there is evidence to suggest that drug-drug interactions between clopidogrel and PPIs may translate to worse cardiovascular outcomes. Studies demonstrating PPI superiority in the setting of DAPT were also limited due to small sample sizes and high levels of bias. Consequently, there is renewed interest in H2RAs for patients on DAPT with some data demonstrating similar or improved clinical outcomes over PPI therapy. Additionally, studies have discovered a possible role for H2RAs in the management of heart failure (HF) incidence, symptoms, and mortality. Studies comparing H2RAs and PPIs in patients on DAPT have demonstrated mixed results for cardiovascular and GIB outcomes, with several studies being underpowered and limited by biases. Recent clinical and pre-clinical studies now support the noninferiority of H2RAs for major outcomes and even utility in HF. These findings suggest that H2RAs may warrant reconsideration as an acid suppressive therapy over PPIs for patients on DAPT or with HF.

Structural characterization of the optical isomers esomeprazole and omeprazole using the JADER and FAERS databases. Toxicol Appl Pharmacol 2023; 475:116632.

Abstract
BACKGROUND It is unclear whether the s (-) form of esomeprazole (EPZ) has an improved safety profile when compared with its racemic form omeprazole (OPZ). We assessed the potential complications of these optical isomers when combined with cilostazol, clopidogrel, and prasugrel, which are frequently used concomitant medications. METHODS Using two adverse event spontaneous reporting databases, Japanese Adverse Drug Event Report (JADER) and FDA Adverse Event Reporting System (FAERS), adverse event names for hemorrhage, venous/arterial embolization, and thrombus were obtained from the Medical Dictionary for Regulatory Activities. Reported odds ratios were calculated using a 2 × 2 contingency table, and a signal was considered present if the lower limit of the 95% confidence interval was >1. RESULTS In combination with cilostazol, a hemorrhagic signal for OPZ in JADER and arterial emboli and thrombus signals for EPZ were detected in both databases. In combination with clopidogrel, OPZ showed arterial emboli and thrombus signals in JADER and venous/arterial emboli and thrombus signals in FAERS, while EPZ displayed arterial emboli and thrombus signals in FAERS. In contrast, when in combination with prasugrel, there were no adverse event signals in either database. CONCLUSION This study has confirmed using big data, that EPZ, the optical isomer and racemic form of omeprazole, has the beneficial characteristics of being less sensitive to CYP, as was intended by its design.

Abstract
Aspirin, other antiplatelet agents, and anticoagulant drugs are used across a wide spectrum of cardiovascular and cerebrovascular diseases. A concomitant proton pump inhibitor (PPI) treatment is often prescribed in these patients, as gastrointestinal complications are relatively frequent. On the other hand, a potential increased risk of cardiovascular events has been suggested in patients treated with PPIs; in particular, it has been discussed whether these drugs may reduce the cardiovascular protection of clopidogrel, due to pharmacodynamic and pharmacokinetic interactions through hepatic metabolism. Previously, the concomitant use of clopidogrel and omeprazole or esomeprazole has been discouraged. In contrast, it remains less known whether PPI use may affect the clinical efficacy of ticagrelor and prasugrel, new P2Y12 receptor antagonists. Current guidelines recommend PPI use in combination with antiplatelet treatment in patients with risk factors for gastrointestinal bleeding, including advanced age, concurrent use of anticoagulants, steroids, or non-steroidal anti-inflammatory drugs, and Helicobacter pylori (H. pylori) infection. In patients taking oral anticoagulant with risk factors for gastrointestinal bleeding, PPIs could be recommended, even if their usefulness deserves further data. H. pylori infection should always be investigated and treated in patients with a history of peptic ulcer disease (with or without complication) treated with antithrombotic drugs. The present review summarizes the current knowledge regarding the widespread combined use of platelet inhibitors, anticoagulants, and PPIs, discussing consequent clinical implications.

Abstract
Introduction: Most hepatically cleared drugs are metabolized by cytochromes P450 (CYPs), and Clinical Pharmacogenetics Implementation Consortium (CPIC) guidelines provide curated clinical references for CYPs to apply individual genome data for optimized drug therapy. However, incorporating novel pharmacogenetic variants into guidelines takes considerable time. Methods: We comprehensively assessed the drug metabolizing capabilities of CYP2C19 variants discovered through population sequencing of two substrates, S-mephenytoin and omeprazole. Results: Based on established functional assays, 75% (18/24) of the variants not yet described in Pharmacogene Variation (PharmVar) had significantly altered drug metabolizing capabilities. Of them, seven variants with inappreciable protein expression were evaluated as protein damaging by all three in silico prediction algorithms, Sorting intolerant from tolerant (SIFT), Polymorphism Phenotyping v2 (PolyPhen-2), and Combined annotation dependent depletion (CADD). The five variants with decreased metabolic capability (<50%) of wild type for either substrates were evaluated as protein damaging by all three in silico prediction algorithms, except CADD exact score of NM_000769.4:c.593T>C that was 19.68 (<20.0). In the crystal structure of the five polymorphic proteins, each altered residue of all those proteins was observed to affect the key structures of drug binding specificity. We also identified polymorphic proteins indicating different tendencies of metabolic capability between the two substrates (5/24). Discussion: Therefore, we propose a methodology that combines in silico prediction algorithms and functional assays on polymorphic CYPs with multiple substrates to evaluate the changes in the metabolism of all possible genomic variants in CYP genes. The approach would reinforce existing guidelines and provide information for prescribing appropriate medicines for individual patients.

Abstract
Introduction: Clopidogrel is an antiplatelet medication described as a prodrug, which cannot exert the antiplatelet effect until being biotransformed to the active metabolite. It is commonly used to reduce the risk of blood coagulation in patients diagnosed with acute coronary syndrome, or ischemic stroke.Area covered: We reviewed published articles in PubMed and Google Scholar that focused on the mutations of CYP2C19, CYP3A4, CYP2C9, CYP2B6, and CYP1A2 genes related to clopidogrel clinical efficacy and safety.Expert opinion: Based on current pharmacogenetic studies, patients carrying CYP2C19*2, CYP2C19*3, CYP2C9*3, and CYP2B6*5 alleles may not respond to clopidogrel due to poor platelet inhibition efficacy revealed among them. In contrast, carriers of CYP2C19*17, CYP3A4*1G, and CYP1A2*1C alleles showed a more significant antiplatelet effect in clopidogrel users and expected to have a protective role as a genetic factor against cardiovascular events. Genotyping for either CYP2C19, CYP3A4, CYP2C9, CYP2B6, or CYP1A2 variants is not recommended when considering clopidogrel treatment for patients, as some trials showed specific non-genetic factors (e.g. age and diabetes) that could affect clopidogrel responsiveness. Instead, platelets inhibition tests could be used as predictors of the clinical efficacy of clopidogrel treatment. Other P2Y12 receptor inhibitors should be considered as alternative medications.

Abstract
The unique characteristics of patients with acute coronary syndrome in the Asia-Pacific region mean that international guidelines on the use of dual antiplatelet therapy (DAPT) cannot be routinely applied to these populations. Newer generation P2Y12 inhibitors (i.e. ticagrelor and prasugrel) have demonstrated improved clinical outcomes compared with clopidogrel. However, low numbers of Asian patients participated in pivotal studies and few regional studies comparing DAPTs have been conducted. This article aims to summarise current evidence on the use of newer generation P2Y12 inhibitors in Asian patients with acute coronary syndrome and provide recommendations to assist clinicians, especially cardiologists, in selecting a DAPT regimen. Guidance is provided on the management of ischaemic and bleeding risks, including duration of therapy, switching strategies and the management of patients with ST-elevation and non-ST-elevation MI or those requiring surgery. In particular, the need for an individualised DAPT regimen and considerations relating to switching, de-escalating, stopping or continuing DAPT beyond 12 months are discussed.

Abstract
Aspirin and P2Y12 receptor antagonists are widely used across the spectrum of cardiovascular and cerebrovascular diseases. Gastrointestinal complications, including ulcer and bleeding, are relatively common during antiplatelet treatment and, therefore, concomitant proton pump inhibitor (PPI) treatment is often prescribed. However, potential increased risk of cardiovascular events has been suggested for PPIs, and, in recent years, it has been discussed whether these drugs may reduce the cardiovascular protection by aspirin and, even more so, clopidogrel. Indeed, pharmacodynamic and pharmacokinetic studies suggested an interaction through hepatic CYP2C19 between PPIs and clopidogrel, which could translate into clinical inefficacy, leading to higher rates of cardiovascular events. The FDA and the EMA sent a warning in 2010 discouraging the concomitant use of clopidogrel with omeprazole or esomeprazole. In addition, whether the use of PPIs may affect the clinical efficacy of the new P2Y12 receptor antagonists, ticagrelor and prasugrel, remains less known. According to current guidelines, PPIs in combination with antiplatelet treatment are recommended in patients with risk factors for gastrointestinal bleeding, including advanced age, concurrent use of anticoagulants, steroids or non-steroidal anti-inflammatory drugs, and Helicobacter pylori infection. Like vitamin K antagonists (VKAs), DOACs can determine gastrointestinal bleeding. Results from both randomized clinical trials and observational studies suggest that high-dose dabigatran (150 mg bid), rivaroxaban and high-dose edoxaban (60 mg daily) are associated with a higher risk of GI bleeding as compared with apixaban and warfarin. In patients taking oral anticoagulant with GI risk factor, PPI could be recommended, even if usefulness of PPIs in these patients deserves further data. Helicobacter pylori should always be searched, and treated, in patients with history of peptic ulcer disease (with or without complication). Given the large number of patients treated with antithrombotic drugs and PPIs, even a minor reduction of platelet inhibition or anticoagulant effect potentially carries a considerable clinical impact. The present joint statement by ANMCO and AIGO summarizes the current knowledge regarding the widespread use of platelet inhibitors, anticoagulants, and PPIs in combination. Moreover, it outlines evidence supporting or opposing drug interactions between these drugs and discusses consequent clinical implications.

Abstract
INTRODUCTION Patients with cardiovascular disease are commonly affected by a number of comorbidities leading to a high prevalence of polypharmacy. Polypharmacy increases the probability of drug-drug interactions (DDIs). Amongst these, DDIs involving clopidogrel, the most commonly utilized platelet P2Y12 inhibitor, is a topic of potential clinical concern. AREAS COVERED This article reviews DDIs between clopidogrel and drugs which are widely used in clinical practice. In particular, drugs shown to interfere with the pharmacodynamic and pharmacokinetic effects of clopidogrel and the clinical implications of these findings are reviewed. These drugs include inhibitors of gastric acid secretion, statins, calcium channel blockers, antidiabetic agents, and antimicrobial agents. For the references, we searched PubMed, EMBASE, or the Cochrane Library. EXPERT OPINION Clopidogrel-drug interactions are common. Most of these DDIs are limited to laboratory findings showing an impact on clopidogrel-induced antiplatelet effects. While variability in clopidogrel-induced antiplatelet effects is known to affect clinical outcomes, with high platelet reactivity being associated with thrombotic complications among patients undergoing coronary stenting, most studies assessing the clinical implications of clopidogrel-drug interactions have not shown to significantly affect outcomes. However, awareness of these DDIs remains important for optimizing the selection of concomitant therapies.

Abstract
Background The clinical implications of potential interactions between proton pump inhibitors (PPIs) and clopidogrel have been debated for over a decade. Objective We assessed the association between combined clopidogrel–PPI treatment and the risk of recurrent myocardial infarction (MI) and three secondary outcomes. Patients and Methods A nested case–control study was conducted within Cerner Corporation’s Health Facts® database. A retrospective cohort of patients who experienced a first MI and started clopidogrel treatment was created. Within this cohort, patients experiencing a second MI (cases) were matched with up to five controls. Logistic regression was used to estimate adjusted odds ratios (aORs). Findings were compared with those obtained from models with three negative control exposure drugs: H2 receptor antagonists, prasugrel, and ticagrelor. Results In total, 2890 recurrent MI cases were identified within 12 months following entry into the cohort of clopidogrel users (N = 52,006). aOR for PPI use versus non-use among clopidogrel users was 1.08 [95% confidence interval (CI) 0.95–1.23]. Similar ORs were obtained for secondary endpoints. A positive association between combined use of clopidogrel/PPIs and increased risk of MI was seen in the group aged 80–89 years (aOR 1.26; 95% CI 1.05–1.51). No associations with MI were observed for (1) H2 receptor antagonist use versus non-use among clopidogrel users or (2) PPI use versus non-use among prasugrel users or among ticagrelor users. Conclusions Overall, our findings do not support a significant adverse clinical impact of concomitant clopidogrel/PPI use by patients with MI. Nonetheless, investigation of the possible association seen in those aged 80–89 years may be warranted.

Abstract
AbstractClopidogrel (CLOP) is widely used worldwide for cardiovascular complications. CLOP is highly metabolized in the liver to its active metabolite by cytochrome P450 enzymes. Studies have shown that khat, an addictive substance, is a powerful inhibitor of cytochrome P450 enzymes and can influence the metabolism of drugs that are concomitantly used. Therefore, this study was designed to evaluate the effects of khat on the pharmacokinetics of CLOP in rats. In this study, rats were administered either CLOP alone or CLOP combined with khat and their plasma were obtained at different time intervals and analyzed using the newly developed and validated liquid chromatography with tandem mass spectrometry (LC-MS/MS) method using foretinib (FTB) as the internal standard. The corresponding peak area of the analyte versus FTB was used for calculating the peak ratio. The validated LC-MS/MS method resulted in the separation of the well-defined quantifiable peaks of CLOP, FTB, and CLOP metabolite within 7 min. Results showed a significant influence of khat on the peak ratio of CLOP metabolite, which was found to be significantly decreased (P < 0.05) in comparison to CLOP alone, suggesting significant decrease in the conversion of CLOP to its active metabolite due to the inhibition of CYP450 enzymes by khat. Therefore, there might be a need for dose adjustment for regular khat chewers using CLOP.

Abstract
Background Despite great advances with the introduction of ticagrelor and prasugrel in the treatment of acute coronary syndromes (ACS), the risk of thrombosis and bleeding remains significant and affects the choice of clinicians in the treatment of the single patient. Large registries are effective tools to explore patterns of drug administration and adherence to guideline recommendations in real-world clinical practice. Methods START- antiplatelet is a prospective, observational registry carried out by seven Italian cardiology institutions on patients admitted for ACS aimed to document the real world treatment of ACS patients, adding also data on 12-month follow-up. We present data on the first 1050 patients who have completed 1-year follow-up on a total of 1537 patients. Primary end-points were: 1) MACCE (Major Adverse Cardiovascular and Cerebrovascular Events) including all-cause and cardiovascular mortality, non fatal MI, urgent revascularization, TIA and ischemic stroke; 2) Major and minor bleeding according to TIMI, GUSTO and ISTH classifications Results The dual antiplatelet treatment most prescribed was aspirin plus ticagrelor (47.9%) and aspirin plus clopidogrel (32.1%). At a mean follow-up was 335±131 days, both ticagrelor and prasugrel are associated with a statistically significant reduced total and cardiovascular mortality. Both prasugrel and ticagrelor do not show a significant increased incidence of major and minor bleedings with respect to clopidogrel. Patients with monotherapy had significantly higher incidence of both ischemic stroke and major bleedings. Discussion The analysis of the register has documented that both ticagrelor and prasugrel are associated with a statistically significant reduced total and cardiovascular mortality but both do not show a significant increased incidence of major and minor bleedings with respect to clopidogrel.

Abstract
BACKGROUND Older people with Intellectual Disability (ID) have a high prevalence of gastrointestinal conditions such as Gastro-Oesophageal Reflux Disease (GORD). However, despite this, information about treatment, in particular the use of Proton Pump Inhibitors (PPIs), in this population is sparse and limited. OBJECTIVE To investigate the prevalence and pattern of PPI use among older people with ID. METHOD Data on PPI use and key demographics was analysed from Wave 2 (2013/2014) of IDS-TILDA, a nationally representative longitudinal study of 677 participants aged 40 years and above in Ireland. Descriptive statistics, bivariate analyses and binary logistic regression were carried out. RESULTS Just over a quarter, 27.9% (n = 189), of participants reported use of PPIs, and 53.4% (n = 101) were female. The largest proportion of PPI users (53.4%) were aged between 50 and 64 yrs. Most of the PPIs were used in maximum doses (66.7%). However only 43.9% of PPI users had an indication for PPI use (GORD, stomach ulcer or/and an NSAID use), and further 13.2% were also taking an antiplatelet agent. Use among those in residential care homes (54.3%) was much higher than for those living independently or with family (7%). PPI use among those who have severe/profound ID was 25% higher than those with mild ID. Information about the length of PPI use was missing for 31.2%, but of those with data, just over half recorded using the PPIs for more than a year. Apart from an indication, the factors associated with PPI use were older ages (≥50 years), severe/profound level of ID. CONCLUSION PPI use among older people with intellectual disability is prevalent and frequently long term, often without a clear indication. PPI use especially among those with severe/profound ID and those who live in residential care homes, could predispose these individuals to additional comorbidities and in order to avoid inappropriate long term of use regular review is required.

Trends in concomitant clopidogrel and proton pump inhibitor treatment among ACS inpatients, 2000-2016. Eur J Clin Pharmacol 2018; 75:227-235.

Abstract
PURPOSE The US Food and Drug Administration (FDA) issued three safety announcements between January 2009 and October 2010 warning against concomitant use of clopidogrel and proton pump inhibitors (PPIs) due to a potential drug-drug interaction that may attenuate clopidogrel's antiplatelet activity. This primary objective of this study was to examine trends in concomitant clopidogrel/PPI use among acute coronary syndrome (ACS) inpatients in the US between 2000 and 2016, in relation to the FDA safety communications. METHODS Adult inpatients with a primary diagnosis of ACS were identified from the Cerner Health Facts® database. The standardized (age, sex, race, and census region) prevalence of clopidogrel use with PPIs was calculated yearly and quarterly. Findings were stratified by PPIs' potential to inhibit clopidogrel's activity and by age. RESULTS A total of 204,533 inpatients were identified. In 2008, the prevalence of concomitant clopidogrel and PPI treatment was 34.9%, decreasing to 24.4 and 16.4% in 2009 and 2010, respectively, with the decline being similar across age groups. Treatment with inhibiting PPIs (omeprazole and esomeprazole) and clopidogrel has continued to decrease since 2010, with a prevalence of 0.8% in 2016. A similar reduction was not observed with clopidogrel and non-inhibiting PPIs (pantoprazole, lansoprazole, rabeprazole, and dexlansoprazole). During the FDA warning period, the combined treatment with clopidogrel and H2 receptor antagonists, an alternative to PPIs suggested by the FDA, temporarily increased from 7.8% in 2008 to 12.8 and 14.5% in 2009 and 2010, respectively. CONCLUSIONS Findings suggest that clinical practice recommendations made by the FDA were followed. Further research is needed to determine how changes in drug labels and the availability of new drugs may have influenced the observed trends.

Abstract
BACKGROUND AND OBJECTIVE Diabetes mellitus is associated with an increased risk of stroke and poor outcome following a stroke event. We assessed the impact of discharge treatment with aspirin versus clopidogrel on the 10-year survival of patients with type 2 diabetes after a first-ever noncardioembolic acute ischemic stroke (AIS). METHODS This was a post hoc analysis of the Athens Stroke Outcome Project. Study outcomes included death, stroke recurrence, and a composite cardiovascular disease (CVD) end point (recurrent stroke, myocardial infarction, unstable angina, coronary revascularization, aortic aneurysm rupture, or sudden death). Kaplan-Meier survival curve and Cox regression analyses were performed. RESULTS A total of 304 (93 women) diabetic patients receiving either aspirin (n = 197) or clopidogrel (n = 107) were studied. The 10-year survival was better in clopidogrel-treated patients than in aspirin-treated patients (19 deaths [17.7%] for clopidogrel versus 55 deaths [27.9%] for aspirin; log-rank test: 4.91, P = .027). Similarly, clopidogrel was associated with a favorable impact on recurrent stroke (12 events [11.2%] for clopidogrel versus 39 events [19.7%] for aspirin; log-rank test: 4.46, P = .035) and on the composite CVD end point (21 events [19.6%] for clopidogrel versus 54 events [27.4%] for aspirin; log-rank test: 4.17, P = .041). In the multivariable analysis, the beneficial effect of clopidogrel over aspirin on both primary and secondary end points was independent of age, gender, the presence of CVD or CVD risk factors, and stroke severity. CONCLUSIONS Our findings indicate a favorable effect of clopidogrel at discharge compared with aspirin in preventing death, recurrent stroke, and CVD events in diabetic patients with a first-ever noncardioembolic AIS.

Abstract
BACKGROUND Antiplatelet response to clopidogrel and its influence upon the risk of cardiovascular adverse events among patients with stable coronary artery disease undergoing percutaneous coronary intervention (PCI) has not been investigated fully. METHODS Two hundred eleven patients treated with aspirin and clopidogrel were included in the study. Immediately before PCI, residual platelet reactivity testing with impedance aggregometry assay and a single-nucleotide polymorphism genotyping analysis targeting variants of CYP2C19, ABCB1, and PON1 genes was performed. After the index PCI, the patients were screened for cardiovascular events 6 months following bare-metal stent implantation or 12 months following drug-eluting stent implantation. RESULTS High on-treatment platelet reactivity (HTPR) was observed in 19.43% individuals and low-TPR (LTPR) in 26.54%. In multivariate analysis, HTPR was significantly (p < 0.05) associated with a history of diabetes, higher systolic blood pressure, and platelet count comparing to that of other patients. LTPR was significantly associated with no history of hypertension, younger age, lower platelet count, absence of the CYP2C19*2 variant, and lower CRP plasma level. Overall, cardiac adverse events were noted in 14.23% patients. Survival analysis with the Cox proportional hazard model showed no influence of residual platelet reactivity during clopidogrel therapy upon both ischemic and hemorrhagic events. However, significant predictors for composite of major adverse cardiac events and hospitalization for cardiovascular causes were identified (the higher CCS class prior to coronary intervention and the higher creatinine serum concentration). CONCLUSIONS The platelet response to clopidogrel has no impact upon post-procedural adverse events at mid-term follow-up in patients with stable CAD undergoing PCI. This finding suggests that routine platelet reactivity testing is not beneficial in this group of patients.

Abstract
Proton pump inhibitors (PPIs) are the most effective gastric acid-suppressing agents and the mainstay medical therapy for a series of acid peptic diseases. In general, the safety profile of PPIs is excellent. However, with long-term drug administration, the safety and potency of PPIs has been questioned. In the cardiovascular field, drug-drug interactions related to PPIs have been identified with particular attention regarding the use of PPIs combined with clopidogrel in patients with acute coronary syndrome. Currently, cardiovascular risks from PPIs may extend from patients with coronary artery disease to the general population. This review summarizes the possible cardiovascular risks in PPI users with no history of cardiovascular diseases and discusses possible biological mechanisms.

Abstract
Gastrointestinal haemorrhage is a common clinical scenario and, in those using antithrombotic agents, the risk is significantly increased. Management of these patients, in terms of initial resuscitation is well established and numerous guidelines exist in this area. However, few studies have addressed the subsequent dilemma of if and when antithrombotic agents should be reintroduced. Consequently, practice is variable and not necessarily evidenced-based. Overall, for patients that are either anticoagulated or using antiplatelet drugs for secondary prophylaxis, there is a clear benefit to restarting these agents. However, there is limited data to guide when this should occur. For individuals at low risk of re-bleeding, current guidelines suggest single agent aspirin can be continued without interruption, assuming haemostatic control has been confirmed endoscopically. For those at higher bleeding risk, aspirin should be withheld, but reintroduced early (within 3 days of index endoscopy). However, randomised evidence is lacking, as are studies including more modern agents or combined anticoagulant/ antiplatelet regimens. As such, guidance statements are limited and management suggestions must be extrapolated from clinical trials, retrospective studies and data relating specifically to warfarin and aspirin. The intention of this review is to summarise what evidence is available and, where this is lacking, suggest pragmatic management options based on a risk-benefit assessment of thromboembolism and recurrent bleeding.

[PMID: 28189362 DOI: 10.1016/j.clinthera.2017.01.011] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2016] [Revised: 12/19/2016] [Accepted: 01/06/2017] [Indexed: 12/16/2022]
Abstract
PURPOSE We performed a systematic review of patient-centered outcomes after the concomitant use of proton pump inhibitors (PPIs) and other drugs. METHODS We searched 4 databases in July 2016 to find studies that reported mortality and morbidity after the concomitant use of PPIs and other drugs. We conducted direct meta-analyses using a random-effects model and graded the quality of evidence according to the Grading of Recommendations Assessment, Development and Evaluation working group approach. FINDINGS We included data from 17 systematic reviews and meta-analyses, 16 randomized controlled trials, and 16 observational studies that examined the concomitant use of PPIs with medications from 10 drug classes. Low-quality evidence suggests that the use of PPIs is associated with greater morbidity when administered with antiplatelet drugs, bisphosphonates, antibiotics, anticoagulants, metformin, mycophenolate mofetil, or nelfinavir. Concomitant PPIs reduce drug-induced gastrointestinal bleeding and are associated with greater docetaxel and cisplatin response rates in patients with metastatic breast cancer. For demonstrated statistically significant relative risks and benefits from concomitant PPIs, the magnitudes of the effects are small, with <100 attributable events per 1000 patients treated, and the effects are inconsistent among specific drugs. Among individual PPIs, the concomitant use of pantoprazole or esomeprazole, but not omeprazole or lansoprazole, is associated with an increased risk for all-cause mortality, nonfatal myocardial infarction, or stroke. Clopidogrel is associated with a greater risk for myocardial infarction compared with prasugrel. Conflicting results between randomized controlled trials and observational studies and high risk for bias in the body of evidence lessened our confidence in the results. IMPLICATIONS Available evidence suggests a greater risk for adverse patient outcomes after the concomitant use of PPIs and medications from 9 drug classes and warns against inappropriate drug combinations.

Abstract
PURPOSE We review the use of oral antiplatelet (OAP) therapies in acute coronary syndrome (ACS) management for nurse practitioners (NPs), focusing on current guideline recommendations. DATA SOURCES Treatment guidelines and clinical articles from PubMed. CONCLUSIONS Guidelines recommend that dual antiplatelet therapy with a P2Y12 inhibitor and aspirin be initiated for ACS management. The P2Y12 inhibitor clopidogrel has established efficacy, but is associated with suboptimal and delayed platelet inhibition and variability in response. The newer P2Y12 inhibitors prasugrel and ticagrelor have demonstrated superior efficacy outcomes versus clopidogrel. Consequently, non-ST-segment elevation ACS (NSTE-ACS) guidelines now recommend that ticagrelor be used in preference to clopidogrel for patients treated with stents or managed medically. Because of their higher potency, prasugrel and ticagrelor are associated with increased bleeding rates versus clopidogrel, but with no increased risk of severe or life-threatening bleeding. Guidelines recommend dual antiplatelet therapy be continued ≥12 months in both medically managed and stented ACS patients, and in some cases beyond this, in absence of high bleeding risk. Updated guidelines assign preference to ticagrelor over clopidogrel for maintenance therapy in patients with NSTE-ACS and ST-elevation myocardial infarction. IMPLICATIONS FOR PRACTICE Enhanced NP understanding of OAP agents and current guidelines could contribute to improved ACS patient management.

Abstract
It is well known that critically ill patients require special attention and additional consideration during their treatment and management. The multiple systems and organ dysfunctions, typical of the critical patient, often results in different patterns of enteral absorption in these patients. Anti-platelet drugs are the cornerstone in treating patients with coronary and cerebrovascular disease. Dual anti-platelet therapy with aspirin and clopidogrel is the treatment of choice in patients undergoing elective percutaneous coronary interventions and is still widely used in patients with acute coronary syndromes. However, despite the use of dual anti-platelet therapy, some patients continue to experience cardiovascular ischemic events. Recurrence of ischemic events is partly attributed to the fact that some patients have poor inhibition of platelet reactivity despite treatment. These patients are considered low- or non-responders to therapy. The underlying mechanisms leading to resistance are not yet fully elucidated and are probably multifactorial, cellular, genetic and clinical factors being implicated. Several methods have been developed to asses platelet function and can be used to identify patients with persistent platelet reactivity, which have an increased risk of thrombosis. In this paper, the concept of anti-platelet therapy resistance, the underlying mechanisms and the methods used to identify patients with low responsiveness to anti-platelet therapy will be highlighted with a focus on aspirin and clopidogrel therapy and addressing especially critically ill patients.

Abstract
Dual anti-platelet therapy with aspirin and a P2Y12 inhibitor is the standard of care for patients with acute coronary syndromes (ACS) and for patients undergoing percutaneous coronary intervention (PCI). Clopidogrel is associated with increased risk of high on-treatment platelet reactivity (HTPR) compared to ticagrelor and prasugrel. Investigators have therefore sought to "escalate" clopidogrel dosing to overcome HTPR to reduce ischemic/thrombotic events. In this review, we will summarize the evidence for dose escalation in the context of genetic determinants of resistance and platelet function data. We will review contemporary clinical trials that have sought to improve delivery of dual antiplatelet therapy to patients with coronary artery disease and discuss the potential of clopidogrel dose escalation in specific populations.

Abstract
Background Coprescribing of clopidogrel and other drugs is common. Available reviews have addressed the drug–drug interactions (DDIs) when clopidogrel is as an object drug, or focused on combination use of clopidogrel and a special class of drugs. Clinicians may still be ignorant of those DDIs when clopidogrel is a precipitant drug, the factors determining the degree of DDIs, and corresponding risk management. Methods A literature search was performed using PubMed, MEDLINE, Web of Science, and the Cochrane Library to analyze the pharmacokinetic DDIs of clopidogrel and new P2Y12 receptor inhibitors. Results Clopidogrel affects the pharmacokinetics of cerivastatin, repaglinide, ferulic acid, sibutramine, efavirenz, and omeprazole. Low efficacy of clopidogrel is anticipated in the presence of omeprazole, esomeprazole, morphine, grapefruit juice, scutellarin, fluoxetine, azole antifungals, calcium channel blockers, sulfonylureas, and ritonavir. Augmented antiplatelet effects are anticipated when clopidogrel is coprescribed with aspirin, curcumin, cyclosporin, St John’s wort, rifampicin, and angiotensin-converting enzyme inhibitors. The factors determining the degree of DDIs with clopidogrel include genetic status (eg, cytochrome P540 [CYP]2B6*6, CYP2C19 polymorphism, CYP3A5*3, CYP3A4*1G, and CYP1A2-163C.A), species differences, and dose strength. The DDI risk does not exhibit a class effect, eg, the effects of clopidogrel on cerivastatin versus other statins, the effects of proton pump inhibitors on clopidogrel (omeprazole, esomeprazole versus pantoprazole, rabeprazole), the effects of rifampicin on clopidogrel versus ticagrelor and prasugrel, and the effects of calcium channel blockers on clopidogrel (amlodipine versus P-glycoprotein-inhibiting calcium channel blockers). The mechanism of the DDIs with clopidogrel involves modulating CYP enzymes (eg, CYP2B6, CYP2C8, CYP2C19, and CYP3A4), paraoxonase-1, hepatic carboxylesterase 1, P-glycoprotein, and organic anion transporter family member 1B1. Conclusion Effective and safe clopidogrel combination therapy can be achieved by increasing the awareness of potential changes in efficacy and toxicity, rationally selecting alternatives, tailoring drug therapy based on genotype, checking the appropriateness of physician orders, and performing therapeutic monitoring.

Abstract
Basic life science research holds the promise of personalizing medical care. However, translation steps from the laboratory to the bedside are not trivial. Results from clinical research are difficult to replicate in part because study cohorts are poorly defined phenotypically. Here, we discuss how computer technology can improve the collection of clinical data to enable translation of insights from basic science to validated clinical guidelines.

Abstract
Despite a substantial evidence base, implementation of pharmacogenetics into routine patient care has been slow due to a number of non-trivial practical barriers. We implemented a Personalized Anti-platelet Pharmacogenetics Program (PAP3) for cardiac catheterization patients at the University of Maryland Medical Center and the Baltimore Veterans Administration Medical Center Patients' are offered CYP2C19 genetic testing, which is performed in our Clinical Laboratory Improvement Amendment (CLIA)-certified Translational Genomics Laboratory. Results are returned within 5 hr along with clinical decision support that includes interpretation of results and prescribing recommendations for anti-platelet therapy based on the Clinical Pharmacogenetics Implementation Consortium guidelines. Now with a working template for PAP3, implementation of other drug-gene pairs is in process. Lessons learned as described in this article may prove useful to other medical centers as they implement pharmacogenetics into patient care, a critical step in the pathway to personalized and genomic medicine.
