Amoxicillin carbonate?

Amoxicillin carbonate is a salt form of the antibiotic amoxicillin. The active drug is amoxicillin; the carbonate part is just the counterion used to form a salt for the formulation.

What that means in practice:
- Amoxicillin is most commonly supplied as amoxicillin trihydrate or amoxicillin sodium. Amoxicillin carbonate is a less common salt form and isn’t the standard presentation you’ll see in many countries.
- The antimicrobial effect and dosing are driven by the amount of amoxicillin (the active drug) in the product, not the specific salt. So labeled doses (e.g., mg of amoxicillin per tablet) are what matter.
- The salt form can affect things like solubility and how the drug is absorbed a little, but for typical clinical use the same mg of amoxicillin yields similar activity after accounting for the salt.

If you have a product labeled as “amoxicillin carbonate,” please share the exact dosing (mg per tablet or per mL) or the country/brand. I can help interpret the label, compare it to more common forms (trihydrate or sodium), and summarize dosing guidelines and safety considerations.
