The exact incidence of drug-induced hyperglycemia and diabetes remains unknown; however, evidence suggests that glucocorticoid therapy, antipsychotic agents, cardiovascular drugs (statins, β-blockers, diuretics), certain anti-infective and anticancer drugs, mTOR inhibitors/immunosuppressive agents, and tyrosine kinase inhibitors are associated with disturbances in glucose metabolism and an increased risk of hyperglycemia and/or diabetes [23,184,187,188]. The gene discussed is MTOR; the disease is Hyperglycemia.
