Most potential DDIs are preventable, but it remains a significant problem to patients and the health care system. Among the risk factors associated to DDIs include older age, comorbidities, polypharmacy and hospital stay for long time. DDIs are a considerable clinical problem in the hospitalized cardiac patients, cancer patients, hypertensive patients, and patients with immunodeficiency virus (HIV) and hepatitis C virus (HCV) infections. Best management of DDIs involves the assessment of the interaction; decision to prescribe, dispense, or manage the interacting combination; follow-up monitoring and suitable patient counseling.
