Amlodipine vs. Amlodipine Besylate: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on December 18, 2023
Amlodipine is a calcium channel blocker used to treat hypertension, while amlodipine besylate is the besylate salt form of amlodipine, more stable and easier to formulate in medications.

Key Differences

Amlodipine is a drug in the dihydropyridine class of calcium channel blockers. While, amlodipine besylate is the same drug in a salt form, combined with benzenesulfonate (besylate) for stability.
The pure form of amlodipine is rarely used in medications due to stability issues. Amlodipine besylate, on the other hand, is commonly used in pharmaceuticals due to its improved stability and solubility.
Both are used to treat high blood pressure and angina, but the besylate form is more commonly prescribed due to its formulation. The effectiveness of both in treating cardiovascular conditions is the same.
In the body, amlodipine besylate converts to amlodipine, meaning their bioavailability and absorption rates are essentially the same.
The pharmacokinetics, including how the body metabolizes and eliminates the drug, are the same for both forms. The besylate component does not significantly alter the drug’s action.
