A Systematic Review on Adherence to Oral Antidiabetic Drugs in Patients With Type 2 Diabetes Mellitus

Abstract

Type 2 diabetes mellitus (DM) is a chronic metabolic disorder in which prevalence has been increasing steadily all over the world and one of the main reason for this is poor adherence to oral anti-diabetic drugs, which can lead to therapy failure and increase risk of complications. So we planned this systematic review with an aim to get an adherence estimation to oral anti-diabetic drugs in type 2 diabetes mellitus patients for which a literature search was performed in pubmed, Google Scholar, scopus, and central databases to find observational studies on therapeutic adherence in users of oral anti-diabetic drugs. Our analyses showed that adherence rate to oral anti-diabetic drugs therapy ranged from 23 to 90%. This review confirms that many patients for whom diabetes medication was prescribed were poor compliers with treatment of oral anti-diabetic drugs.
