Hyperglycemia secondary to consumption of cocaine and atypical antipsychotic drugs.

Drugs such as cocaine and atypical antipsychotic agents, such as olanzapine, are sometimes related to hyperglycemia. Whereas cocaine raises plasma glucose through catecholamine release, atypical antipsychotic agents mainly increase appetite and induce weight gain and the development of metabolic syndrome. Moreover, the latter group of drugs also act independently from weight gain or adiposity, due to inhibition of beta pancreatic cells and reduction of peripheral insulin action.
