The price of oseltamivir phosphate API in India varies depending on factors such as the manufacturer, quality, quantity, and current market demand. Specific pricing details are not publicly available through general information sources.
How is oseltamivir phosphate API manufactured?
Oseltamivir phosphate, the active pharmaceutical ingredient (API) in Tamiflu, is synthesized through a complex multi-step chemical process. One common route involves starting materials derived from shikimic acid, which can be sourced from star anise [1]. The synthesis requires careful control of reaction conditions and purification steps to ensure the final product meets pharmaceutical standards.
Who are the major manufacturers of oseltamivir phosphate API in India?
Several Indian pharmaceutical companies are involved in the production of oseltamivir phosphate API. These include manufacturers who supply both domestic and international markets. Companies like Laurus Labs, Hetero Drugs, and Mylan (now Viatris) have been noted in the context of oseltamivir production [2][3]. The landscape of API manufacturers is dynamic, with other companies also potentially involved.
When does oseltamivir phosphate patent expiry occur?
The original patents for oseltamivir phosphate have largely expired in major markets. For example, key patents in the United States expired around 2016-2018, opening the door for generic competition [4]. Patent expiry dates can vary by country and depend on patent term extensions and other legal factors. Information on specific patent statuses can be found through specialized patent databases [5].
Can biosimilars of oseltamivir phosphate enter the market?
Oseltamivir phosphate is a small molecule drug, not a biologic. Therefore, the term "biosimilar" is not applicable. Instead, generic versions of oseltamivir phosphate can enter the market after the expiry of relevant patents and the successful completion of regulatory approval processes by generic drug manufacturers.
What is the general price range for oseltamivir phosphate finished dosage forms?
While API pricing is not readily available, the price of finished oseltamivir phosphate capsules (e.g., 75 mg) in India can range from approximately ₹20 to ₹50 per capsule, depending on the brand and the pharmacy [6]. This price reflects the finished product cost, including manufacturing, packaging, distribution, and regulatory compliance, in addition to the API cost.
What are the regulatory requirements for oseltamivir phosphate API in India?
API manufacturers in India must comply with stringent regulations set by the Central Drugs Standard Control Organization (CDSCO) for manufacturing, quality control, and distribution. This includes adherence to Good Manufacturing Practices (GMP) and submission of Drug Master Files (DMFs) to regulatory authorities for approval of the API used in finished drug products.
