Is sirolimus rapamycin?

Is sirolimus rapamycin the same thing?

Yes. Sirolimus is also known as rapamycin. Both names refer to the same drug (an mTOR inhibitor) [1].

Why are there two names (sirolimus vs. rapamycin)?

“Rapamycin” is the original name of the compound, while “sirolimus” is the pharmaceutical name used for the approved drug. In practice, you can treat them as interchangeable when reading medical literature, prescriptions, or drug labeling [1].

What is sirolimus/rapamycin used for?

Common uses include preventing transplant rejection and treating certain cancers, depending on the specific product and indication. The brand and formulation (for example, transplant vs. topical) can differ, but the active drug substance remains sirolimus/rapamycin [1].

Where can I confirm this for a specific product?

Check the drug’s “active ingredient” section or prescribing information for the exact naming used. DrugPatentWatch.com also tracks drug identities and related filings under the sirolimus/rapamycin naming [1].
