Adherence with ethinylestradiol 20 μg/drospirenone 3 mg in a flexible extended regimen supported by the use of a digital tablet dispenser with or without acoustic alarm: an open-label, randomized, multicenter study

Evaluation of adherence to a daily progestin-only pill in a simulated over-the-counter setting

OBJECTIVE

The Adherence with Continuous Dose Oral Contraceptive: Evaluation of Self-Selection and Use (ACCESS) study assessed whether consumers can adhere to the regimen for a progestin-only pill (norgestrel 0.075 mg) in an over-the-counter (OTC) setting.

STUDY DESIGN

An actual use study in a simulated OTC environment assessed adherence to directions to take norgestrel 0.075 mg every day at the same time in 883 participants for up to 24 weeks.

RESULTS

Eighty-five percent (747/883) of participants reported ≥85% adherence to taking norgestrel 0.075 mg every day and reported taking their dose within three hours of their scheduled dosing time on 96% of days. When accounting for use of a condom for 48 hours if a pill was missed, participants reported correctly following the label's directed use for 97% of doses overall, with 95% of participants following label directions for ≥85% of doses. The main limitations were related to finding a balance between intensely collecting data to ensure accurate assessment of adherence and leaving users to behave as they would in a real OTC situation without healthcare practitioner intervention. We observed that some participants reported taking more doses than they could have based on the supply of medication given to them. To fully examine the situation, and the impact on the conclusions, additional post hoc sensitivity analyses were performed, and showed remarkably consistent results.

CONCLUSIONS

Consumers were highly adherent to taking norgestrel 0.075 mg when using only the information provided by the proposed OTC label.

IMPLICATIONS

Adherence to a daily oral contraceptive pill was high when obtained OTC. This suggests that effectiveness of an OTC pill is likely to be like that of a prescribed pill and easier access to this effective contraceptive should allow more opportunity to prevent pregnancy.

Artificial intelligence in the field of pharmacy practice: A literature review

Artificial intelligence (AI) is a transformative technology used in various industrial sectors including healthcare. In pharmacy practice, AI has the potential to significantly improve medication management and patient care. This review explores various AI applications in the field of pharmacy practice. The incorporation of AI technologies provides pharmacists with tools and systems that help them make accurate and evidence-based clinical decisions. By using AI algorithms and Machine Learning, pharmacists can analyze a large volume of patient data, including medical records, laboratory results, and medication profiles, aiding them in identifying potential drug-drug interactions, assessing the safety and efficacy of medicines, and making informed recommendations tailored to individual patient requirements. Various AI models have been developed to predict and detect adverse drug events, assist clinical decision support systems with medication-related decisions, automate dispensing processes in community pharmacies, optimize medication dosages, detect drug-drug interactions, improve adherence through smart technologies, detect and prevent medication errors, provide medication therapy management services, and support telemedicine initiatives. By incorporating AI into clinical practice, health care professionals can augment their decision-making processes and provide patients with personalized care. AI allows for greater collaboration between different healthcare services provided to a single patient. For patients, AI may be a useful tool for providing guidance on how and when to take a medication, aiding in patient education, and promoting medication adherence and AI may be used to know how and where to obtain the most cost-effective healthcare and how best to communicate with healthcare professionals, optimize the health monitoring using wearables devices, provide everyday lifestyle and health guidance, and integrate diet and exercise.

Adherence among a cohort taking progestin-only pills prescribed by a healthcare provider: Results of the BENCHMARK study

OBJECTIVES

To measure adherence over 6 months of progestin-only pill (POP) use.

STUDY DESIGN

Prospective observational cohort study measuring adherence to daily dosing and timing of dose in patients prescribed a POP, with up to six months of follow-up, conducted from January to October 2020. A pharmacy benefit manager identified potential participants with a newly prescribed POP and extended an invitation to participate. We enrolled qualified respondents by telephone, trained them to use an electronic diary to report daily whether they had taken their POP and at what time. We followed participants for up to six months. We calculated adherence to daily pill taking as the proportion of evaluable days in which a participant took a POP, and the proportion of participants reporting ≥85% adherence. We calculated adherence to same time each day as the proportion of doses taken no later than three hours after the previous dose time of day.

RESULTS

The user population comprised 199 participants, 154 (77.4%) of whom completed six months of follow-up. The majority (n=170, 85.4%) were taking norethindrone. Norethindrone users reported POP intake on 22,327 (96.4%) of 23,156 evaluable days, with 155 (91.2%) participants reporting ≥85% adherence; less than half (n=73, 42.9%) reported 100% adherence. Participants reported adherence to same time each day on 21,698 of 22,157 (97.9%) evaluable days.

CONCLUSIONS

Among participants taking a prescribed POP, participants demonstrated high adherence for daily pill taking and the same time of day, though the majority were not 100% adherent.

IMPLICATIONS

This study reports data specific to adherence among those taking a progestin-only pill (POP) in the prescription setting. Clinicians who counsel patients about POP use should be aware that majority of patients were not 100% adherent, although most report ≥ 85% adherence.

Evaluation of the efficacy, safety, and clinically recommended dose of dienogest in the treatment of primary dysmenorrhea: a randomized, double-blind, multicenter, placebo-controlled study

OBJECTIVE

To evaluate the efficacy, safety, and clinically recommended dose of dienogest (DNG; 0.5 mg/d, 1 mg/d, and 2 mg/d) in the treatment of primary dysmenorrhea.

DESIGN

A phase II, randomized, double-blind, multicenter, placebo-controlled study.

SETTING

Twenty study sites.

PATIENTS

A total of 235 patients with primary dysmenorrhea.

INTERVENTION(S)

Patients were randomized to receive orally a placebo, DNG (0.5 mg/d, 1 mg/d, or 2 mg/d) or ethinylestradiol 0.02 mg/drospirenone 3 mg (an open-label reference drug) for 12 weeks.

MAIN OUTCOME MEASURE(S)

The primary endpoint was the change from baseline in the dysmenorrhea score at week 12 of treatment. The secondary endpoint was the change from baseline in the visual analogue scale at week 12 of treatment. Subjects were assessed for lower abdominal pain and/or low back pain.

RESULTS

All DNG arms were superior to the placebo arm in terms of the change from baseline in the dysmenorrhea score. The results suggest an equal or greater effect of DNG 1 and 2 mg/d in relieving pain, when compared to the reference drug. In the safety profile of DNG, including irregular uterine bleeding, there was no obvious difference among the doses of DNG. A significant decrease in the serum estradiol concentration compared to that in the placebo arm was not observed in the DNG 1 mg/d arm but was observed in the DNG 2 mg/d arm.

CONCLUSION(S)

The results suggest that DNG at a dose of 1 mg/d is an effective and well-tolerated treatment for primary dysmenorrhea.

Medication management needs information and communications technology-based approaches, including telehealth and artificial intelligence

Life expectancy is rising in most parts of the world as is the prevalence of chronic diseases. Suboptimal adherence to long-term medications is still rather the norm than the exception, although it is well known that suboptimal adherence compromises the therapeutic effectiveness. Information and communications technology provides new concepts for improving adherence to medications. These so-called telehealth concepts or services help to implement closed-loop healthcare paradigms and to establish collaborative care networks involving all stakeholders relevant to optimising the overall medication therapy. Together with data from Electronic Health Records and Electronic Medical Records, these networks pave the way to data-driven decision support systems. Recent advances in machine learning, predictive analytics, and artificial intelligence allow further steps towards fully autonomous telehealth systems. This might bring advances in the future: disburden healthcare professionals from repetitive tasks, enable them to timely react to critical situations, and offer a comprehensive overview of the patients' medication status. Advanced analytics can help to assess whether patients have taken their medications as prescribed, to improve adherence via automatic reminders. Ultimately, all relevant data sources need to be collated into a basis for data-driven methods, with the goal to assist healthcare professionals in guiding patients to obtain the best possible health status, with a reasonable resource utilisation and a risk-adjusted safety and privacy approach. This paper summarises the state-of-the-art of telehealth and artificial intelligence applications in medication management. It focuses on 3 major aspects: latest technologies, current applications, and patient related issues.

The Impact of Two Combined Oral Contraceptives Containing Ethinyl Estradiol and Drospirenone on Whole Blood Clot Viscoelasticity and the Biophysical and Biochemical Characteristics of Erythrocytes

Venous thrombosis is associated with combined oral contraceptive (COC) use. We investigated the impact of two ethinyl estradiol (EE) and drospirenone (DRSP) containing COCs (3 mg DRSP/20 µg EE and 3 µg DRSP/30 µg EE) on the viscoelasticity of whole blood clots along with the biophysical and biochemical characteristics of erythrocytes. Thromboelastography (TEG) analysis showed a tendency toward a hypercoagulable state in the COCs groups that was more pronounced with higher EE concentrations. Light microscopy and scanning electron microscopy (SEM) showed rouleaux formation of erythrocytes and alterations to the erythrocyte shape for both COC groups, which was attributed to membrane damage. SEM analysis showed spontaneous activation of fibrin and platelets in the COC groups, along with interactions between erythrocytes and platelets and/or fibrin. Confocal microscopy confirmed compromised membrane integrity in the COC groups compared to controls. Global thrombosis test analysis showed increased platelet activation and low thrombolysis in both COC groups when compared to controls. In conclusion, DRSP/EE formulations impact erythrocytes' biophysical and biochemical properties to cause a shift in hemostasis to a prothrombotic state. Although these effects are mostly subclinical the long-term effects and risks involved with the use of these hormones should be considered carefully for each individual.

An observational study of adherence to combined oral contraceptive regimens

OBJECTIVE

To analyze adherence to an oral contraceptive (OC) regimen and correlate results to participants' socio-demographic and behavioral characteristics.

METHODS

Women were prospectively enrolled and followed for 6 months. At enrollment, subjects were given a card for recording daily pill intake; its completion was checked at 6 months when women completed a self-administered questionnaire.

RESULTS

Out of 755 eligible subjects, 704 agreed to participate; 402 women completed 6 months of recording of use of an OC and properly filled the questionnaire. Good adherence was reported by 64% of participants; 20.9% missed one pill and 14.9% missed more than one pill. Mean number of missed pills per subject was 0.59 and mean number of pills delayed for less than 24 h was 1.18. Best adherence to a COC regimen was associated with evening time intake (p = 0.0019). No statistically significant associations of adherence with socio-demographic characteristics were found. Age was only marginally associated with having missed at least one pill.

CONCLUSION

In the present study, a lower number of missed pills were observed than previously reported, but the proportion of missed pills was similar. No association with specific subject characteristics that could serve as markers of increased risk of nonadherence was found.

Adherence to a flexible extended regimen for oral hormonal contraception provided in blister packaging compared with an adherence-supporting digital tablet dispenser: historical comparison of data from two clinical studies

BACKGROUND

The Clyk™ digital pill dispenser helps ensure correct and consistent administration of a flexible extended regimen of the combined oral contraceptive, ethinylestradiol (EE) 20 μg/drospirenone 3 mg (EE/drospirenone ; YAZ(®) Flex Flex), guiding users through the intake cycle and 4-day pill break and providing visible and acoustic daily reminders when pill intake is due. A study showed that the audible alarm function of the dispenser could help reduce the number of missed pills, but it lacked an appropriate "non-dispenser" group for a meaningful assessment of the impact of the dispenser on adherence. This study indirectly assessed the overall effect of the digital dispenser on adherence by comparing data from a treatment with standard blister packaging.

MATERIALS AND METHODS

One-year adherence data were compared from two similarly designed, Phase III, open-label, randomized trials of EE/drospirenoneFlex. In study 1, women used diary cards to record adherence with EE/drospirenoneFlex dispensed in blister packs (n=640), and in study 2 the dispenser was used with the alarm activated (n=250) or deactivated (n=248) in addition to using diary cards.

RESULTS

A mean (±SD) of 4.3 (±4.24) missed pills over 1 year were recorded in diary cards among women who dispensed their pills from the blister packages (study 1) compared with 1.0 (±2.4) recorded by the alarm-activated dispenser (study 2). In study 2, a mean of 1.9 (±4.2) missed pills were reported in the diaries over 1 year compared with 4.4 (±9.1) from automatic recording by the dispenser (both arms of study 2), indicating underreporting of missed pills in diary cards vs the digital dispenser. Adjusting for this rate of underreporting, an estimated mean of ten pills were missed over 1 year by women using EE/drospirenoneFlex in blister packs, or ten times more than with the digital dispenser with activated acoustic alarm.

CONCLUSION

The digital dispenser helps reduce the number of missed pills and increases adherence.

Contraception for women with epilepsy: counseling, choices, and concerns

Approximately 50% of all pregnancies in women with epilepsy (WWE) occur unplanned. This is worrying, given the increased occurrence of obstetrical complications in WWE, including the risk of seizures and their possible consequences for both the mother and the unborn child. Hormonal contraception is usually regarded as highly effective, but it is subject to numerous bidirectional drug interactions with several antiepileptic drugs. These interactions may lead to loss of seizure control or contraceptive failure. Further concerns are loss of bone mineral density and increased seizure activity due to hormonal effects. Many physicians lack sufficient knowledge regarding these issues, and most WWE have never received adequate counseling. Moreover, several studies show that a large proportion of WWE do not take their medicines regularly. This article reviews all of these issues and offers practical recommendations for the management of contraception in WWE.
