What interactions does amlodipine show?

Please note that the interactions may vary depending on the drug formulation of a drug (eg tablet, syringe, ointment).

The hypotensive effect of amlodipine may be enhanced by other antihypertensives and tricyclic antidepressants. When combined with nitrates, the effects on blood pressure and heart rate may increase. Concurrent use of amlodipine and beta-blockers requires careful medical monitoring of patients, as the hypotensive effects may increase. Beta-blockers can worsen myocardial insufficiency, so patients with heart failure should be monitored with extra care by the doctor during concomitant treatment with amlodipine. The same applies to the administration of antiarrhythmic drugs such as amiodarone and quinidine, since amlodipine may also reduce cardiac output in addition to the antiarrhythmic drugs.

When taken with amlodipine and sildenafil (an erectile dysfunction remedy), each drug has its own antihypertensive effect on its own.

Amlodipine is broken down in the body by an enzyme whose activity can be affected by many other agents. Concurrent administration therefore requires careful medical supervision.

Substances that inhibit this enzyme may cause amlodipine to degrade more slowly when administered concomitantly and then be more potent and longer. These substances include: the fungicides ketoconazole and itraconazole, the antihypertensive drug diltiazem, HIV-1 protease inhibitors (for AIDS), the macrolide antibiotics clarithromycin, erythromycin and telithromycin and the antidepressant nefazodone.

Likewise, agents that promote the activity of the enzyme may attenuate the amlodipine effect. This is the case with the tuberculosis drugs rifampicin and rifabutin, the AIDS drug nevirapine, St. John’s wort (for depression), the glucocorticoid dexamethasone and the antiepileptic drugs phenobarbital, phenytoin and carbamazepine.
