What is the appropriate route of administration for oseltamivir?

Oseltamivir is an antiviral medication primarily used in the treatment and prevention of influenza. The appropriate route of administration for oseltamivir is oral. This medication is formulated as a capsule or a liquid suspension, meant to be taken by mouth.

When oseltamivir is ingested, it is rapidly absorbed from the gastrointestinal tract, allowing it to circulate effectively in the bloodstream and exert its therapeutic effects against the influenza virus. This oral administration route is not only convenient but also well-tolerated by patients, making it a practical choice for both treatment and prophylaxis.

Intravenous and subcutaneous routes are typically reserved for medications that require direct entry into the bloodstream or cannot be effectively absorbed through the digestive tract. Inhalation would also not be appropriate for oseltamivir, as it is not designed for respiratory administration. Oral administration ensures the proper pharmacokinetics of the drug, facilitating adequate absorption and distribution within the body to combat the flu effectively.
