Flutavir Capsule 75 mg contains Oseltamivir, an antiviral medication belonging to the neuraminidase inhibitor class. It is widely used for the treatment and prevention of influenza infections caused by influenza A and B viruses. Flutavir Capsule 75 mg helps reduce the severity and duration of flu symptoms when initiated promptly and also lowers the risk of complications associated with influenza, especially in high-risk individuals.

Indications

Flutavir Capsule 75 mg is indicated for:

• Prophylaxis of influenza following exposure to infected individuals

• Prevention of influenza outbreaks in high-risk populations

For optimal effectiveness, treatment should be started within 48 hours of the onset of flu symptoms.

Therapeutic Class

Antiviral Agent / Neuraminidase Inhibitor

Pharmacology

Oseltamivir is a prodrug that is rapidly converted in the liver to its active metabolite, oseltamivir carboxylate. This active form selectively inhibits the neuraminidase enzyme on the surface of influenza viruses. By blocking neuraminidase, oseltamivir prevents the release of newly formed viral particles from infected host cells, thereby limiting viral replication and spread within the respiratory tract. This mechanism helps shorten the duration of illness and reduce symptom severity when administered early in the course of infection.

Dosage and Administration

• Treatment of Influenza: 75 mg twice daily for 5 days

• Prophylaxis of Influenza: 75 mg once daily for at least 7–10 days following exposure

• Elderly: No dose adjustment is generally required unless renal impairment is present

• Pediatric: Dosage is based on body weight and should be prescribed by a physician

Capsules should be taken orally and may be administered with food to reduce gastrointestinal discomfort.

Drug Interactions

Flutavir Capsule 75 mg has a low potential for drug interactions. However, co-administration with probenecid may increase plasma concentrations of oseltamivir. Patients should inform their healthcare provider about all medications they are taking before initiating therapy.
