Out-patient compliance with antidepressant medication.

Area of Science:

• Psychiatry
• Clinical Pharmacology

Background:

• Medication adherence is crucial for effective treatment of depression.
• Optimizing antidepressant dosing schedules is essential for improving patient compliance.

Purpose of the Study:

• To compare the efficacy and compliance of different antidepressant dosing regimens in depressed out-patients.
• To investigate the impact of patient choice on medication adherence and therapeutic outcomes.

Main Methods:

• 89 depressed out-patients were randomized into three groups: once-daily dosing, three-times-daily dosing, or patient-chosen regimen.
• Medication compliance was assessed via interrogation and pill counts at 3, 6, 9, and 12 weeks.
• Depression severity and side-effects were monitored concurrently.

Main Results:

• No significant overall difference in therapeutic outcomes was found between doctor-prescribed and patient-chosen regimens, or between once-daily and three-times-daily dosing.
• Patients allowed to choose their regimen, particularly the three-times-daily option, demonstrated significantly better compliance.
• A consistent decline in compliance was observed across all groups over the 12-week study period.

Conclusions:

• Patient preference for dosing schedules can enhance medication compliance in depression treatment.
• Despite improved compliance with chosen regimens, this did not translate to better therapeutic results, suggesting multifactorial influences on treatment efficacy.
• Further research is needed to understand the discrepancy between compliance and therapeutic outcomes.
