Are the Patients Ready for the Change?: An Empirical Study to Evaluate the Impact of Change in Formulation of Buprenorphine-Naloxone on Prescription Pattern, Treatment Adherence, and Patient Satisfaction

Abstract

Background: Therapeutic adherence is one of the most important determinants of the outcome with OST. There are no published studies that have explored the impact of change in tablet formulation of buprenorphine-naloxone from one brand to another among patients receiving OST. Objectives: The current study is aimed at evaluation of the impact of change in buprenorphine-naloxone formulation on prescription pattern, treatment adherence, and patient satisfaction with OST. Methods: Our study was a cross sectional study based on a cohort of patients who were receiving OST at the study setting. Changes in prescription pattern, reports of subjective opioid withdrawal symptoms, or observation of objective opioid withdrawal symptoms were noted from the case records. The satisfaction and concerns of the patients with buprenorphine-naloxone formulations were assessed using a semi-structured proforma. Results: An increase in dose of buprenorphine-naloxone was noted in 22 participants, since formulation change. Twenty participants reported that the color of the formulation was different from the previous one, the intensity of effect was reported to be different by 87% participants. Seventy-three percent participants endorsed that increase in dose can be a possible solution to address the perceived differences in the effects of two formulations. Changes in physical attributes of the formulation, perception among treatment seeking peers regarding such changes in treatment, and lack of sense of autonomy regarding one’s treatment play a more important role in determining response of the patients to changes in formulation of buprenorphine-naloxone.
