Lipinox Tablets (Amlodipine as Besylate) by Life Pharmaceutical Company

Drug Category: Calcium antagonists

Indication:  Amlodipine (Besylate) is primarily indicated in conditions like Angina pectoris, Essential hypertension, Hypertension, Prophylaxis of angina, Vasospastic angina.

Composition:

Each Tablet contains:

  • Amlodipine (as Besylate)…………………….5mg/ 10mg

Pharmacological Action:

  • Amlodipine (Besylate): Amlodipine decreases arterial smooth muscle contractility and subsequent vasoconstriction by inhibiting the influx of calcium ions through L-type calcium channels. Calcium ions entering the cell through these channels bind to calmodulin. Calcium-bound calmodulin then binds to and activates myosin light chain kinase (MLCK). Activated MLCK catalyzes the phosphorylation of the regulatory light chain subunit of myosin, a key step in muscle contraction. Signal amplification is achieved by calcium-induced calcium release from the sarcoplasmic reticulum through ryanodine receptors. Inhibition of the initial influx of calcium decreases the contractile activity of arterial smooth muscle cells and results in vasodilation. The vasodilatory effects of amlodipine result in an overall decrease in blood pressure. Amlodipine is a long-acting CCB that may be used to treat mild to moderate essential hypertension and exertion-related angina (chronic stable angina). Another possible mechanism is that amlodipine inhibits vascular smooth muscle carbonic anhydrase I activity causing cellular pH increases which may be involved in regulating intracelluar calcium influx through calcium channels.
