Oncovin (Vincristine Sulfate)

Pfizer Inc. · FDA-approved approved Small molecule Quality 65/100

Vincristine Sulfate (Oncovin), marketed by Pfizer Inc., is a well-established chemotherapy agent primarily indicated for acute leukemia, with a key composition patent expiring in 2028. Its mechanism of action, which disrupts cell division by binding to tubulin, provides a strong therapeutic profile against its primary indication. The primary risk is the competition from off-patent generics of same-class drugs such as vinblastine and vinorelbine, which may erode market share.
