In what form is Oseltamivir administered to patients?

Oseltamivir is administered in the form of oral capsules or a suspension, making it suitable for a wide range of patients, including those who may have difficulty swallowing pills. This oral administration allows for easy dosage adjustments and is convenient for use at home, enabling effective treatment against influenza virus infections. The formulation is designed to be absorbed through the gastrointestinal tract, where it is converted into its active form to inhibit viral replication, thereby helping to alleviate the severity and duration of influenza symptoms.

The other forms mentioned, such as injectable, topical cream, or inhaler, are not applicable to Oseltamivir's mode of administration and do not fit its pharmacological profile or usage guidelines. This focus on an oral delivery system aligns well with the typical treatment pathway for outpatients experiencing influenza.
