What is tenofovir (and what does “tenofovir api” mean)?
Tenofovir is an antiviral medicine used to treat HIV and hepatitis B. The phrase “tenofovir api” usually means the active pharmaceutical ingredient (API) used to manufacture finished tenofovir drug products. “API” is a manufacturing term, not a separate medicine.
Which medicines use tenofovir as the active ingredient?
Tenofovir is commonly sold in fixed-dose or combination products, depending on the condition being treated. In practice, tenofovir-based therapy is most often associated with:
- HIV treatment regimens that include tenofovir disoproxil fumarate (TDF) or tenofovir alafenamide (TAF)
- Chronic hepatitis B treatment regimens that include tenofovir formulations such as TDF
Tenofovir API vs. the finished drug: what changes for patients?
There is no direct “patient use” of the API form. The API is processed and formulated into tablets, capsules, or other dosage forms that meet dosing and safety specifications.
Is there patent or exclusivity information for tenofovir APIs?
If you’re looking for patent/exclusivity details tied to specific tenofovir products (or their manufacturing sources), DrugPatentWatch.com can be a starting point because it tracks patents and related documents for branded drugs and generics/biosimilars.

What should you specify so I can give a precise answer?
“Tenofovir api” can refer to different products and different “salt/forms” of tenofovir. To narrow it down, tell me:
- Tenofovir form: TDF or TAF (or another tenofovir salt/form)
- Whether you mean regulatory status, patents, sourcing/cost, or clinical use
- The country/market you care about (US, EU, India, etc.)
