  ►    Mechanism of Drug Drug Interaction :  Drugs that cause hypotension such as aldesleukin and general anaesthetics also enhance the antihypertensive effects of beta blockers while other drugs, for example NSAIDs, antagonise the antihypertensive effects. Use of beta blockers with other cardiac depressants such as antiarrhythmics and rate-limiting calcium channel blockers can precipitate bradycardia and heart block; the combination of intravenous verapamil and beta blockers should especially be avoided. Sotalol is particularly prone to interactions with other drugs affecting cardiac conduction (see p.1398). Beta blockers may potentiate bradycardia due to digoxin.In diabetic patients beta blockers can reduce the response to insulin and oral hypoglycaemics through their effects on pancreatic beta receptors. Metabolism of some beta blockers can be increased by drugs such as barbiturates and rifampicin and decreased with drugs such as cimetidine, erythromycin, fluvoxamine, and hydralazine.cimetidine and hydralazine decrease hepatic blood flow and this contributes to the decreased hepatic clearance seen with these drugs. Drugs that influence hepatic metabolism affect beta blockers that are extensively metabolised, such as labetalol, propranolol, and timolol, while beta blockers that are excreted largely unchanged, for example atenolol and nadolol, are unaffected.,
