title: Aminophylline reversal of antihypertensive agent toxicity.
abstract: Hypotension occurred following a combined beta blocker (atenolol), angiotensin converting enzyme inhibitor (quinapil) and selective serotonin reuptake inhibitor (fluvoxamine) overdose. In another instance heart block and hypotension was noted in association with a diltiazem and atenolol adverse interaction. Crystalloid infusion was ineffective in both cases, but toxicity was rapidly reversed with aminophylline administration. Aminophylline's recognized inotropic and chronotropic properties make it a potentially valuable therapeutic agent in the treatment of antihypertensive medication toxicity.
