ABSTRACT

Drugs used in the treatment of cardiovascular disorders and diabetes are among the most

commonly prescribed medications in the United States. Figures 1 and 2 show a classification

of cardiovascular and antidiabetic medications. Use of these agents has continuously

increased due to the improved recognition of these disorders and their complications.

Additionally, the ever-growing problem of obesity and the metabolic syndrome has caused

an increase in the incidence of diabetes, dyslipidemia, hypertension, and subsequent coronary

artery disease and dysrhythmias. There is high prevalence of nonalcoholic fatty liver disease

(NAFLD) and nonalcoholic steatohepatitis (NASH) in patients with obesity, diabetes, and

dyslipidemia, and distinguishing medication-induced liver disease from underlying liver

disease can be difficult. This leads to difficulty in distinguishing whether the liver disease is

due to cardiovascular or diabetic drugs themselves or is a manifestation of underlying liver

disease resulting from metabolic disorders and diabetes. Evolving data suggest that patients

with diabetes may have higher risk of drug-induced liver disease than nondiabetic individ-

uals. Diabetic patients who take oral hypoglycemics have a higher risk of developing drug-

induced liver disease than those not taking these medications (1,2). An excellent review was

recently published by Wang and colleagues that provided a detailed review of existing human

and animal studies supporting the notion that patients with diabetes are generally at higher

risk for developing drug hepatotoxicity (3).
