Cocaine and beta blockers

Cocaine abuse is an important cause of neurological disease in some populations. Seizures, psychiatric disorders and cerebrovascular disease are among the most commons clinical presentations. It is important to remember that in patients with hypertension and documented or suspected use of cocaine, beta blockers are not usually recommended due to the unopposed alpha agonist effect in the heart that can lead to coronary vasoconstriction and cardiac ischemia. When indicated, other drugs should be used to treat hypertension.
