Understanding the Generic Name for Etravirine
When discussing medications, it is common to encounter both a brand name and a generic name. The generic for etravirine, the active ingredient in the brand-name drug Intelence, is also etravirine. This medication is classified as a non-nucleoside reverse transcriptase inhibitor (NNRTI) and is used as part of a combination therapy to manage HIV-1 infection.
How Etravirine Works
Etravirine is a second-generation NNRTI primarily used in treating HIV, especially in patients resistant to older NNRTIs. It inhibits reverse transcriptase, an enzyme crucial for HIV replication. By binding to this enzyme, etravirine prevents the virus from converting its RNA into DNA, thus slowing viral replication. Its ability to adapt to certain mutations gives it an advantage over first-generation NNRTIs.
Generic vs. Brand-Name: The Availability of Etravirine
The brand-name version, Intelence®, was FDA-approved in 2008. Generic equivalents became available after patent expiration and FDA approval, with the first generic shipping in July 2021.
The Importance of Generic Equivalents
Generic medications must have the same active ingredient, strength, dosage form, and administration route as their brand-name counterparts. Generic etravirine works identically to Intelence®. Key benefits of generics include:
- Lower Cost: Generics are generally less expensive, improving affordability and access.
- Increased Accessibility: Generic availability can help address supply chain issues.
- Healthcare Savings: Reduced costs benefit patients and the healthcare system.

Generic Etravirine vs. Brand-Name Intelence
While therapeutically equivalent, there are some differences.
| Feature | Generic Etravirine | Brand-Name Intelence |
|---|---|---|
| Active Ingredient | Etravirine | Etravirine |
| Manufacturer | Amneal Pharmaceuticals and others | Janssen Therapeutics |
| Cost | Typically lower | Typically higher |
| Appearance | May differ | Consistent brand appearance |
| FDA Approval | Requires an Abbreviated New Drug Application (ANDA) | Requires a New Drug Application (NDA) |
| Formulation | Equivalent to brand name, adheres to strict FDA standards | Original patented formulation |
Conclusion
The generic name for etravirine is etravirine, the same active ingredient in Intelence. Generic availability has enhanced access to this crucial HIV medication, particularly for those resistant to first-generation NNRTIs. Both versions are therapeutically equivalent and manage HIV-1 by inhibiting reverse transcriptase. Patients should consult healthcare providers and pharmacists about their options and adherence.
