Are you confused about the different forms of amlodipine?

Let us help you understand the key variations between amlodipine maleate and besylate.

Known as calcium channel blockers, both amlodipine maleate and besylate are commonly prescribed medications for treating high blood pressure and angina. While they share similar therapeutic benefits, it is important to know that they differ in their chemical composition and potential side effects.

What is maleate?

Maleate is the salt form of maleic acid. It is often used in pharmaceuticals as a component in drug formulations to enhance stability and solubility. Maleate salts are known to have certain advantages over other salt forms, such as improved bioavailability and better compatibility with excipients. Maleate salts are commonly used in the formulation of drugs for various therapeutic areas, including cardiovascular diseases, central nervous system disorders, and respiratory conditions.

In the case of amlodipine maleate, maleate is the salt form of amlodipine, which is a calcium channel blocker used to treat high blood pressure and chest pain (angina). Maleate salt of amlodipine provides the necessary stability and solubility for the drug to be effective in its intended therapeutic applications.

Amlodipine maleate is generally well-tolerated and has a favorable safety profile. It is available in various dosage forms, including tablets and oral solutions, and is typically prescribed by healthcare professionals based on individual patient needs and medical history.

What is besylate?

What is besylate?

Besylate is a salt form of the drug amlodipine. It is commonly used as a medication to treat high blood pressure and angina (chest pain). Amlodipine besylate belongs to a class of drugs known as calcium channel blockers, which work by relaxing the blood vessels and improving blood flow.

Unlike amlodipine maleate, amlodipine besylate is formulated with benzenesulfonic acid, which enhances the drug’s stability and solubility. This ensures that the medication is easily absorbed when taken orally, providing consistent and reliable effects.

Amlodipine besylate is typically prescribed in tablet form and is taken once daily. It is important to follow the dosing instructions provided by your healthcare provider to ensure optimal results.

Benefits of amlodipine besylate:

Benefits of amlodipine besylate:

Amlodipine besylate offers several benefits for individuals with high blood pressure or angina:

  • Reduces blood pressure: Amlodipine besylate helps lower blood pressure by relaxing the blood vessels, allowing blood to flow more easily.
  • Treats angina: By improving blood flow to the heart, amlodipine besylate can relieve chest pain caused by angina.
  • Long-lasting effects: The drug’s extended-release formula ensures a continuous effect throughout the day, providing stable blood pressure control.
  • Well-tolerated: Amlodipine besylate is generally well-tolerated, with minimal side effects. Common side effects may include headache, dizziness, and swelling in the feet or ankles.


Amlodipine besylate is an effective and widely prescribed medication for the treatment of high blood pressure and angina. Its formulation with benzenesulfonic acid ensures stability and solubility, allowing for consistent absorption and reliable therapeutic effects. If you have been prescribed amlodipine besylate, it is important to take the medication as directed by your healthcare provider. Remember to consult with your healthcare provider about any concerns or questions you may have regarding the medication.

What is besylate?

Besylate is a salt form of amlodipine that is commonly used in medication formulations. It is an organic compound that is created by reacting amlodipine with benzenesulfonic acid. The addition of the besylate salt to amlodipine helps to increase its solubility and stability, making it easier to manufacture and administer as a medication.

The use of besylate in amlodipine formulations allows for better absorption and distribution in the body. It enhances the pharmacological properties of amlodipine, making it more effective in treating conditions such as high blood pressure and chest pain associated with angina.

Besylate is known for its ability to relax and widen the blood vessels, which reduces the workload on the heart and improves blood flow. This helps to lower blood pressure and relieve symptoms of angina, allowing individuals to lead healthier lives.

Benefits of besylate in amlodipine

The incorporation of besylate into amlodipine offers several benefits:

  1. Enhanced solubility: The besylate salt improves the solubility of amlodipine, allowing it to dissolve more easily in the body and be absorbed more efficiently.
  2. Increased stability: Besylate helps to stabilize amlodipine, preventing degradation and ensuring the medication’s effectiveness over time.
  3. Improved bioavailability: The use of besylate in amlodipine formulations enhances the drug’s bioavailability, meaning more of the medication reaches the target tissues and provides therapeutic effects.
  4. Excellent tolerability: Amlodipine besylate is generally well-tolerated by patients, with few reported side effects.

Overall, besylate plays a crucial role in optimizing the therapeutic properties of amlodipine, making it a widely used and effective medication for the treatment of various cardiovascular conditions.

Differences between amlodipine maleate and besylate

Amlodipine maleate and besylate are both forms of the drug amlodipine, which is a calcium channel blocker used to treat high blood pressure and chest pain. While they are similar, there are some differences between the two:

1. Chemical composition:

Amlodipine maleate and besylate have different chemical compositions. Amlodipine maleate is composed of amlodipine and maleic acid, while amlodipine besylate is composed of amlodipine and besylate salt.

2. Solubility:

The solubility of amlodipine maleate and besylate differs. Amlodipine besylate is more soluble in water than amlodipine maleate. This can affect the rate at which the drug is absorbed and distributed in the body.

3. Stability:

Amlodipine maleate and besylate also differ in terms of stability. Amlodipine maleate is less stable than amlodipine besylate, which means it may have a shorter shelf life and require more careful storage conditions.

4. Bioavailability:

The bioavailability of amlodipine maleate and besylate can vary. Bioavailability refers to the fraction of the drug that reaches the systemic circulation. Differences in bioavailability can affect the efficacy and dosage requirements of the drug.

5. Dosage forms:

Amlodipine maleate and besylate are available in different dosage forms. Amlodipine maleate is commonly found in tablets, whereas amlodipine besylate is available in both tablets and capsules. The choice of dosage form may depend on the patient’s preference or specific medical needs.

Overall, amlodipine maleate and besylate are similar in their therapeutic effects and are both used to treat hypertension and angina. However, the differences in their chemical composition, solubility, stability, bioavailability, and dosage forms make them distinct from each other. It is important to consult with a healthcare professional to determine the most appropriate form of amlodipine for individual patients.
