Antiflu Capsules (Oseltamivir Phosphate) Used to Treat & Prevent Influenza A/B, and Swine Flu (H1N1)
Antiflu (Oseltamivir 75 mg) is an antiviral medication used to treat and prevent influenza (flu) by inhibiting the replication of influenza viruses in the body. Designed for adults and children (with doctor’s guidance), Antiflu lessens the severity and duration of flu symptoms when taken early in infection of Influenza A/B, and Swine Flu (H1N1). It works by stopping viral growth, killing the virus, and preventing its spread.

Containing Oseltamivir Phosphate, this medication belongs to a class of drugs known as neuraminidase inhibitors. It is highly effective in treating acute, uncomplicated influenza in patients who have shown symptoms for no more than two days, and it is also widely used as a preventive measure during flu outbreaks.

Mechanism of Action
Antiflu works by targeting the way the flu virus spreads within the respiratory tract. The process involves:
- Enzyme Inhibition: Oseltamivir blocks the activity of the viral neuraminidase enzyme found on the surface of the virus.
- Preventing Viral Release: By inhibiting this enzyme, the medication prevents newly formed virus particles from budding off and escaping from infected cells.
- Halting Infection Spread: Because the virus cannot exit the host cell, it is unable to infect neighboring healthy cells, effectively stopping the spread of the infection throughout the body.
- Symptom Reduction: This targeted action helps decrease the duration of flu symptoms and reduces the risk of secondary complications like pneumonia.
Key Benefits
- Early Intervention: Significantly shortens the recovery period when taken within the first 48 hours of symptom onset.
- Dual-Type Coverage: Highly effective against both Influenza Type A (including H1N1) and Influenza Type B strains.
- Prophylactic Use: Provides a strong line of defense as a preventive treatment for individuals exposed to the flu.
- Complication Reduction: Lowers the likelihood of severe respiratory issues and hospitalizations associated with the seasonal flu.
- Convenient Dosing: Standardized capsule form ensures precise dosing for adults and adolescents, supporting better patient adherence.
