Amlotab(Amlodipine)

Therapeutic Group: Cardiovascular

Presentation

Amlotab 5 tablet: Each tablet contains Amlodipine Besilate BP equivalent to Amlodipine 5 mg.

Description

Amlodipine is a Dihydropyridine Calcium antagonist that inhibits the transmembrane influx of Calcium ions into cardiac and vascular smooth muscle. It has greater affinity towards vascular smooth muscle than on cardiac muscle. Amlodipine is peripheral vasodilator that acts directly on vascular smooth muscle to cause a reduction in peripheral vascular resistance and thereby reduces blood pressure. Amlodipine reduces tone, decreases coronary vasoreactivity and lowers cardiac oxygen demand by reducing after load.

Indications

Patients with mild to moderate hypertension (alone or in combination with other antihypertensives).

The treatment of chronic stable and vasospastic angina.

Raynaud\'s disease.

Dosage & Administration

For treatment of both hypertension and angina pectoris, the usual initial dose is 5 mg once daily. If the desired therapeutic effect cannot be achieved within 2-4 weeks, the dose may be increased to a maximum dose of 10 mg once daily. Amlodipine 10 mg once daily provides symptomatic improvement in patients with Raynaud's disease.
Use in children: Use of Amlodipine in children (under 12 years of age) is not recommended.

Side Effects

Amlodipine is generally well tolerated. The most commonly observed side effects are headache, peripheral oedema, palpitations, flushing, dizziness, nausea, abdominal pain.

Precautions

Use in renal failure
Although Amlodipine is excreted primarily via kidney, mild renal impairment does not appear to have an effect on the plasma concentrations. Severe renal impairment may however require a dosage reduction. Amlodipine is not dialyzable.

Use in patients with impaired hepatic function
Amlodipine half-life is prolonged in patient with impaired hepatic function. Amlodipine should therefore be administered at lower (5mg) initial dose in these patients.

Use in heart failure
An increased number of pulmonary oedema has been reported.

Use in Pregnancy & Lactation

Pregnancy: Safety in pregnancy has not been established.
Lactation: It is not known whether Amlodipine is excreted in breast milk. It is advised to stop breastfeeding during treatment with Amlodipine.
