Why beta blockers should be avoided in cocaine?

Beta blockers must not be used in the treatment of cocaine, amphetamine, or other alpha adrenergic stimulant overdose.

The appropriate antihypertensive drugs to administer during hypertensive crisis resulting from stimulant abuse are vasodilators like nitroglycerin, diuretics like furosemide and alpha blockers like phentolamine.beta-blocker
