Atypical Antipsychotics - Alter receptor binding characteristics, leading to increased insulin resistance.
Beta-blockers - Inhibit insulin secretion.
Calcium Channel Blockers - Inhibits secretion of insulin by interfering with cytosolic calcium release.
Corticosteroids - Cause peripheral insulin resistance and gluconeogensis.
Fluoroquinolones - Inhibits insulin secretion by blocking ATP sensitive potassium channels.
Naicin - They cause increased insulin resistance due to increased free fatty acid mobilization.
Phenothiazines - Inhibit insulin secretion.
Protease Inhibitors - Inhibit the conversion of proinsulin to insulin.
Thiazide Diuretics - Inhibit insulin secretion due to hypokalemia. They also cause increased insulin resistance due to increased free fatty acid mobilization.
