Contra Indications

Cardiogenic shock, hypotension (systolic pressure <90 mmHg), marked bradycardia, uncompensated heart failure, 2nd- or 3rd-degree AV block (unless pacemaker is fitted), sick-sinus syndrome, severe ventricular dysfunction, atrial flutter or atrial fibrillation and accessory bypass tract (e.g. Wolff-Parkinson-White, Lown-Ganong-Levine syndromes).

Precautions

Patient w/ bradycardia or 1st-degree AV block, attenuated neuromuscular transmission, hypertrophic cardiomyopathy. Avoid abrupt withdrawal. Renal and hepatic impairment. Childn. Pregnancy and lactation. Monitoring Parameters Monitor BP, heart rate, ECG, LFTs (periodically). Lactation: Distributed in milk; nursing infant doses range from <0.01% to 0.1% of mother’s dose; manufacturer suggests refraining from nursing (though American Academy of Pediatrics committee states that drug is compatible with nursing)

Pregnancy-Lactation

Pregnancy category: C Lactation: Distributed in milk; nursing infant doses range from <0.01% to 0.1% of mother’s dose; manufacturer suggests refraining from nursing (though American Academy of Pediatrics committee states that drug is compatible with nursing)

Interactions

Increased cardiac depressant effects with beta-blockers and flecainide. Increased risk of additive bradycardia, conduction disturbances and digoxin toxicity with digoxin. Increased risk of bradycardia and hypotension with remifentanil and sufentanil. Increased levels of both everolimus and verapamil on concurrent use. May increase doxorubicin, buspirone, carbamazepine, ciclosporin, epirubicin, eplerenone, quinidine, statins, sirolimus, tacrolimus, quinupristin/dalfopristin levels. Verapamil increase blood alcohol levels. Unpredictable interactions with lithium. Decreased verapamil concentrations with phenobarbital, sulfinpyrazone, rifampicin, rifabutin and rifapentine. Increased verapamil concentrations with protease inhibitors and cimetidine. Potentially Fatal: Increased cardiac depressant effects with amiodarone. Increased risk of QT prolongation with dofetilide, ranolazine, sertindole. Additive bradycardia with ivabradine. Increased risk of heart block with clonidine. Increased risk of acute hyperkalaemia and CV collapse with dantrolene.

Adverse Effects

Side effects of Verapamil Hydrochloride : >10% Headache, Gingival hyperplasia 1-10% Constipation (9%), Dizziness (4%), Hypotension (4%), Dyspepsia (3%), Nausea (3%), Edema (2%), Rash (2%), Increased liver enzymes (1%), Sleep disturbance (1%), Dyspnea

Mechanism of Action

Verapamil inhibits entry of calcium ions into arterial smooth muscle cells as well as the myocytes and conducting tissue. These actions lead to reversal and preventions of coronary artery spasm, reduction in afterload through peripheral vasodilatation and reduction in ventricular rate in patients with chronic atrial flutter or fibrillation and reduction in the occurrence of paroxysmal supraventricular tachycardia. Verapamil reduces BP, relieves angina and slows AV conduction.
