Does India have amlodipine “free base” tablets, or is it usually amlodipine besylate?
In India, amlodipine is commonly marketed as a salt form (most often amlodipine besylate), because manufacturers and regulators typically list the drug by its salt/strength used in the product. Free-base (amlodipine base) products are less commonly named explicitly in routine market listings compared with salt formulations.
How to find “amlodipine free base” availability in India (what to check on the pack)
When a product is truly the free base rather than a salt, the label and composition typically name it explicitly as “amlodipine” (free base) rather than a salt (for example, “amlodipine besylate”). Practical ways to verify:
- Check the “composition” line for wording like “amlodipine (as free base) … mg.”
- If it lists “as amlodipine besylate,” then it is not the free base product.
- Compare the strength basis: free base vs salt strengths are not interchangeable without conversion.
If you only see amlodipine besylate, is that equivalent to free base?
Clinically, amlodipine besylate and free-base amlodipine deliver the same active moiety (amlodipine) but differ in molecular weight because of the counter-ion (the salt). That means dosing is expressed in terms of amlodipine (base equivalent) even if the listed ingredient is a salt. If you are switching brands, check that the “amlodipine” strength (base equivalent) matches what your prescription specifies.
Why free-base availability might be limited in retail listings
Even when the molecule is the same, commercial availability often follows what the supplier supplies at scale (salt forms are widely used because of formulation, stability, and manufacturing considerations). As a result, free-base naming may be uncommon in Indian retail pharmacy listings even if amlodipine itself is widely available.
What patients should do if they require “free base” specifically
If your prescriber or you specifically need free base (for example, because of a documented intolerance or a formulation requirement), ask the pharmacist to:
- confirm the exact salt/free-base form written in the composition, and
- provide the strength as “amlodipine” (base equivalent), not just the salt weight.
If you share the exact product name/strength you are looking for (or a photo of the “composition” line), I can help interpret whether it is free base or a salt form and how to compare it to an equivalent dose.
Do patents or market authorization affect whether free base can be sold?
For older, widely genericized drugs like amlodipine, patents are less likely to be the reason you cannot find “free base” wording in retail. Availability is more often driven by formulation and what generic manufacturers choose to submit and market (typically salt forms).

What I need from you to answer precisely
“Availability” can mean different things (retail tablets, API, or specific strengths). Tell me:
1) Are you looking for a tablet/capsule brand in pharmacies, or the API/free base powder?
2) What strength (e.g., 5 mg or 10 mg)?
3) Any specific language on the prescription (e.g., “amlodipine free base” vs “amlodipine besylate”)?
