title: Medication Use Among Patients Prior to Bariatric Surgery.
abstract: Purpose:The aims of this study were to describe the most common medications reported by candidates for weight loss surgery and to consider the potential implications for patient care.Methods:A secondary data analysis of data from bariatric surgery patients enrolled in a randomized, controlled trial. At study entry, participants recorded their use of prescription medications they had taken in the previous 90 days. The Anatomical Therapeutic Chemical (ATC)/Defined Daily Dose (DDD) Index 2014 was used to classify medications.Results:Participants (n=265) were 85.7% female and 83.0% white. Mean body mass index was 47.9±6.5 kg/m2, and age was 45.1±11 years. The average number of medications was 4.4±4.1, and the median was 3. The top three anatomical main groups were the cardiovascular system, alimentary tract and metabolism, and nervous system (28.2%, 21.6%, and 21.3% of all medications, respectively). The top therapeutic subgroups were drugs used in diabetes, psychoanaleptics, and agents acting on the renin-angiotensin system (12%, 11.3%, and 8.2% of all medications, respectively).Conclusions:Candidates for weight loss surgery report taking medications associated with obesity-related comorbidities such as diabetes, depression, and hypertension. Although many may be able to eliminate these medications, others will require close monitoring and dosage adjustment after surgery.
