Product Name: Amlodipine Besilate

CAS Number: 111470-99-6

Molecular Formula: C₂₀H₂₅ClN₂O₅

Molecular Weight: 408.89 g/mol

Appearance: White crystalline powder

Description:Amlodipine Besilate is a dihydropyridine calcium channel blocker. It selectively inhibits the transmembrane influx of calcium ions into arterial smooth muscle cells and, to a lesser degree, myocardial cells. This results in the dilation of coronary and systemic arteries, reducing peripheral vascular resistance and consequently lowering blood pressure.

Mechanism of Action:It works by blocking the calcium channels in the heart and blood vessel walls, which reduces the heart's workload and helps the heart to beat more efficiently. This leads to a decrease in blood pressure and may relieve symptoms of angina.

Pharmacological Properties:

• Antihypertensive: Effective in lowering blood pressure in patients with hypertension.

• Angina Relief: Helps to alleviate the symptoms of angina by reducing the heart's oxygen demand.

• Rhythm Regulation: May be used to treat certain heart rhythm disorders.

Clinical Uses:

• Hypertension: As monotherapy or in combination with other antihypertensive agents.

• Angina Pectoris: For the symptomatic treatment of chronic stable angina and variant angina.

• Heart Rhythm Disorders: In certain cases, it may be used to regulate heart rhythm.

Pharmaceutical Applications:

• Formulations: Available in various pharmaceutical formulations such as tablets and capsules for oral administration.

Safety and Precautions:

• Contraindications: Contraindicated in patients with hypersensitivity to the drug.

• Warnings: Should be used with caution in patients with aortic stenosis or heart failure.

• Pregnancy and Lactation: Safety in pregnant women has not been established. Not recommended during breastfeeding.

Pharmacokinetics:

• Absorption: Well-absorbed orally, with peak plasma levels occurring 6-12 hours after administration.

• Half-life: The terminal elimination half-life is about 30-50 hours.

• Metabolism: Extensively metabolized in the liver to inactive metabolites.

• Excretion: Primarily excreted in the urine, with a small amount eliminated unchanged in the feces.

Storage Conditions:

• Storage: Store in airtight containers, protected from light, and at a controlled room temperature.

Packaging:
