Cardiovascular effects of omeprazole and famotidine.
In a randomized, placebo-controlled, double-blind, crossover comparison, 12 patients with congestive heart failure (New York Heart Association class II) and dyspeptic complaints were treated orally for 1 week each with placebo, 40 mg omeprazole daily, and 40 mg famotidine daily. Non-invasive haemodynamic measurements were taken on the last day of treatment. Although omeprazole did not alter cardiac performance in impedance cardiography and mechanocardiography, the administration of famotidine led to a significant fall in stroke volume and cardiac output as compared with placebo (both p less than 0.05). Thus, omeprazole did not exert any relevant cardiovascular effects, in contrast to the H2-receptor antagonist famotidine.[1]References
