Abstract
BACKGROUND Selective serotonin reuptake inhibitors (SSRIs), the most prescribed antidepressants, are associated with a modestly increased risk of major bleeding. However, in patients treated with both SSRIs and oral anticoagulants (OACs), the risk of major bleeding may be substantial. OBJECTIVE To assess the risk of major bleeding associated with concomitant use of SSRIs and OACs, compared with OAC use alone. METHODS We searched MEDLINE, Embase, PsycINFO, and the Cochrane Central Register of Controlled Trials (from inception to December 1, 2021) for clinical trials and observational studies assessing the association between concomitant use of SSRIs and OACs and the risk of major bleeding. Given sufficient homogeneity of studies, we conducted a random-effects meta-analysis to estimate a pooled hazard ratio (HR) of major bleeding associated with concomitant use of SSRIs and OACs, compared with OAC use alone. RESULTS The review comprised 14 studies, including 7 cohort and 7 nested case-control studies. Following assessment of clinical and methodological heterogeneity, eight studies with a total of 98,070 patients were eligible for the meta-analysis. The pooled HR of major bleeding associated with concomitant use of SSRIs and OACs was 1.35 (95% confidence interval [CI]: 1.14-1.58). In secondary analyses, the pooled HR for concomitant use of SSRIs and direct OACs was 1.47 (95% CI: 1.03-2.10). CONCLUSION Concomitant use of SSRIs and OACs was associated with an increased risk of major bleeding. Overall, our findings suggest that physicians may need to tailor treatment according to individual patient risk factors for bleeding when prescribing SSRIs to patients using OACs.

Drug-drug Interactions with Warfarin: A Systematic Review and Meta-analysis. Br J Clin Pharmacol 2021; 87:4051-4100. [PMID: 33769581 DOI: 10.1111/bcp.14833] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2020] [Revised: 03/07/2021] [Accepted: 03/10/2021] [Indexed: 12/13/2022] Open
Abstract
AIM The objective of this paper is to systematically review the literature on drug-drug interactions with warfarin, with a focus on patient-important clinical outcomes. METHODS MEDLINE, EMBASE, and the International Pharmaceutical Abstract (IPA) databases were searched from January 2004 to August 2019. We included studies describing drug-drug interactions between warfarin and other drugs. Screening and data extraction were conducted independently and in duplicate. We synthesized pooled odds ratios (OR) with 95% confidence intervals (CIs), comparing warfarin plus another medication to warfarin alone. We assessed the risk of bias at the study level and evaluated the overall certainty of evidence using GRADE. RESULTS Of 42,013 citations identified, a total of 72 studies reporting on 3,735,775 patients were considered eligible, including 11 randomized clinical trials and 61 observational studies. Increased risk of clinically relevant bleeding when added to warfarin therapy was observed for antiplatelet (AP) regimens (OR=1.74; 95% CI 1.56, 1.94), many antimicrobials (OR=1.63; 95% CI 1.45, 1.83), NSAIDs including COX-2 NSAIDs (OR=1.83; 95% CI 1.29, 2.59), SSRIs (OR=1.62; 95% CI 1.42, 1.85), mirtazapine (OR=1.75; 95% CI 1.30, 2.36), loop diuretics (OR=1.92; 95% CI 1.29, 2.86), and others. We found a protective effect of proton pump inhibitors (PPIs) against warfarin-related gastrointestinal (GI) bleedings (OR=0.69; 95% CI 0.64, 0.73). No significant effect on thromboembolic events or mortality of any drug group used with warfarin was found, including single or dual AP regimens. CONCLUSIONS This review found low to moderate certainty evidence supporting the interaction between warfarin and a small group of medications, which result in increased bleeding risk. PPIs are associated with reduced hospitalization for upper GI bleeding for patients taking warfarin. Further studies are required to better understand drug-drug interactions leading to thromboembolic outcomes or death.

Abstract
Background:
Since warfarin has a very narrow therapeutic index, the interaction between
warfarin and antidepressants is very critical and has potentially severe consequences. It is unclear
whether clinicians have sufficient knowledge about the risk of bleeding when warfarin and antidepressants
are used concomitantly.
Objective:
In this systematic review, we discuss the main considerations when using warfarin with
antidepressants.
Methods:
The information about warfarin-antidepressant interactions was obtained from Google
Scholar®, PubMed/MEDLINE® and a hand search of the published literature. The following research
terms which were systematically combined with each other to find articles: warfarin, anticoagulant,
interactions, antidepressant (and each antidepressant name individually), SSRI, SNRI, TCA, MAOI.
Results:
Several possible mechanisms that can cause bleeding when antidepressants and warfarin
are used concomitantly, have been discussed. According to the available data, sertraline and citalopram/
escitalopram are safer antidepressants to use with warfarin, whereas fluoxetine and fluvoxamine
have a higher interaction potential with warfarin. The remaining antidepressants appear to lie
somewhere in between and have little empirical data to guide the clinicians.
Conclusion:
It is recommended that when an antidepressant is prescribed to a patient using warfarin,
patient’s international normalized ratio (INR) level should be checked regularly. In this review,
the interaction between warfarin and antidepressants, including new ones, were evaluated
inclusively and in detail.

Abstract
PURPOSE The purpose of this study was to assess the possible relation between use of antidepressant (AD) drugs, that is, tricyclic ADs, selective serotonin reuptake inhibitors (SSRIs), and atypical ADs (AAs), and the risk of hospitalization for cardiovascular (CV) events among older patients with previous CV diseases. METHODS A nested case-control study was carried out among patients aged 65 years and older from 5 Italian health care territorial units who were discharged for CV disease during 2008 to 2010. The cohort was composed by 344,747 individuals, and of these, 97,739 (28%) experienced hospital admission for CV events (myocardial infarction, arrhythmia, stroke, heart failure) during follow-up (until 2014) and were included as cases. Up to 5 controls were randomly selected and matched to each. A conditional logistic regression was fitted to estimate the risk of CV events associated with ADs past or current use. A within-patient comparison was performed by the case-crossover design to account the effect of depression. FINDINGS Current users of SSRIs and AAs were at increased risk of CV events with odds ratios of 1.25 (95% confidence interval, 1.21-1.29) and 1.31 (1.25-1.37), respectively. An increased risk of arrhythmia and stroke was associated with current use of SSRIs and AAs, whereas an increased risk of heart failure was detected with current use of any ADs. The results were confirmed by the case-crossover approach. IMPLICATIONS Evidence that AD use is associated with an increased risk of CV events in accordance with specific mechanisms of action among older people with CV disease was added by this study.

Nonsteroidal Anti-inflammatory Drugs Utilization Patterns and Risk of Adverse Events due to Drug-Drug Interactions among Elderly Patients: A Study from Jordan. Saudi Pharm J 2020; 28:504-508. [PMID: 32273811 PMCID: PMC7132832 DOI: 10.1016/j.jsps.2020.03.001] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2020] [Accepted: 03/03/2020] [Indexed: 12/30/2022] Open
Abstract
Background Worldwide, the prescribing pattern of the Nonsteroidal Anti-inflammatory Drugs (NSAIDs) has increased. They are considered highly effective medications in controlling various conditions including inflammatory diseases. They are associated with various adverse effects including gastrointestinal bleeding and ulcer and renal toxicity though. These adverse effects are generally potentiated when NSAIDs are co-prescribed with other drugs that share similar adverse effects and toxicities. Developing severe side effects from NSAIDs is more prone among elderly patients. Hence, it is crucial to evaluate prescribing pattern of these agents to prevent/decrease the number of unwanted side effects caused by NSAIDs. Aim The aim of this study is to assess the prescribing pattern of NSAIDs among elderly and the co-prescribing of NSAIDs and different interacting drugs, which could lead to more incidences of NSAIDs-induced toxicities among Jordanian elderly patients. Settings and Methodology A multicenter retrospective study was performed during a three months period in Jordan. The study involves a total number of (n = 5916) elderly patient’s records obtained from Four governmental hospitals in Jordan. Results A total number of (n = 20450) drugs were prescribed and dispensed for patient. NSAIDs drugs prescribing percentage was 10.3% of total medications number. Aspirin was the most commonly prescribed NSAIDs among patients (70.4%), followed by Diclofenac sodium in all dosage forms (25.1%) and oral Ibuprofen (3.1%. In addition, Aspirin was the highest NSAIDs co-prescribed with ACEI (e.g., Enalapril), ARBs (e.g. Candesartan and Losartan), Diuretics (Furosemide, Indapamide, Hydrochlorothiazide, Amiloride, and Spironolactone), Warfarin and antiplatelets (Clopidogreal and Ticagrelor) followed by Diclofenac and other NSAIDs. Conclusion NSAIDs prescribing rate among elderly patients was high. Additionally the co-prescribing of NSAIDs especially Aspirin with other agents, which contributes to NSAIDs nephrotoxicity and gastrointestinal toxicity, were high. Strict measurements and action plans should be taken by prescribers to optimize the medical treatment in elderly through maximizing the benefits and decreasing the unwanted side effects.

Abstract
BACKGROUND Depression, the leading cause of nonfatal disease burden, has a strong correlation with suicide and affects approximately 7% of the general elderly population. Adverse drug reactions in older patients are particularly important because of reduced drug metabolism, polypharmacy, drug-drug interactions, and drug-disease interactions. Fluoxetine is the first representative selective serotonin reuptake inhibitor but is associated with the possibility of hemorrhage based on its mechanism of action. Serious cases of gastrointestinal bleeding and cerebral hemorrhage have been reported, raising concerns about the safety of this drug. METHODS We detected signals of bleeding risk associated with fluoxetine in an elderly population using the Korea Adverse Event Reporting System database. Reporting odds ratios and 95% confidence intervals (CIs) were calculated. RESULTS A total of 16,517 adverse events related to antidepressants were reported. The reporting odds ratios for fluoxetine were 2.34 (95% CI, 1.03-5.34) for total bleeding, 4.41 (95% CI, 1.60-12.15) for major bleeding, 2.06 (95% CI, 0.28-15.03) for gastrointestinal bleeding, and 6.12 (95% CI, 2.14-22.60) for brain hemorrhage compared with those of all other antidepressants. CONCLUSIONS We detected safety signals with total bleeding, major bleeding, and brain hemorrhage related to fluoxetine. For patients with a high risk of bleeding, such as the elderly population, prescribing antidepressants other than fluoxetine can be considered. The results of this study provide preliminary evidence of a relationship between fluoxetine and hemorrhage but have wide 95% CIs. Further pharmacoepidemiological studies will be needed to confirm the risk of bleeding associated with fluoxetine.

Abstract
BACKGROUND Little is known about the comparative risk of death with atypical or conventional antipsychotics (APs) among persons with cardiovascular or cerebrovascular disease (CCD). RESEARCH DESIGN AND METHODS A cohort study was conducted using five Italian claims databases. New atypical AP users with CCD aged ≥65 (reference) were matched to new conventional AP users. Mortality per 100 person-years (PYs) and hazard ratios (HR), estimated using Cox models, were reported. Incidence and risk of death were estimated for persons having drug-drug interactions. Outcome occurrence was evaluated 180 days after AP initiation. RESULTS Overall 24,711 and 27,051 elderly new conventional and atypical AP users were identified. The mortality rate was 51.3 and 38.5 deaths per 100 PYs for conventional and atypical AP users. Mortality risk was 1.33 (95%CI: 1.27-1.39) for conventional APs. There was no increased mortality risk with single drug-drug interactions (DDIs) vs. no DDI. AP users with ≥1 DDI had a 29% higher mortality risk compared to no DDI in the first 90 days of treatment (HR: 1.29 (95% CI: 1.00-1.67)). CONCLUSIONS Conventional APs had a higher risk of death than atypical APs among elderly persons with CCD. Having ≥1 DDI was associated with an increased risk of death.
