One study found no adverse interaction between naproxen and cimetidine and no alteration in the beneficial effects of cimeti ne on gastric acid secretion, but another study found that cimetidine caused a moderate 39 to 60% decrease in the naproxen half-life, and a 20 /o reduction in the AUC of naproxen. In one of these studies the half-life of naproxen was reduced by about 40% by ranitidine and 50% by famotidine. A further study found that nizatidine does not affect the pharmacokinetics of naproxen. ...
