Generic Name: Entecavir 0.5 mg Tablet Active Ingredient: Entecavir 0.5 mg — a nucleoside analogue antiviral medication Dosage Form: : Oral tablet Strength : 0.5 mg entecavir per tablet Route of Administration : Oral (taken by mouth) Therapeutic Class: : Antiviral agent (specifically used for hepatitis B virus) Mechanism of Action: : Entecavir blocks the viral DNA polymerase enzyme needed for replication of hepatitis B virus (HBV). By inhibiting this viral enzyme, the drug prevents HBV from multiplying in liver cells. Packaging: : Typically available in blister packs of 10 tablets or similar Active ingredient: Entecavir 0.5 mg Class: Antiviral (Nucleoside analogue) Form: Oral tablet Chronic Hepatitis B Infection : Used to treat chronic hepatitis B virus (HBV) infection in adults and children over 2 years. Helps reduce viral load in the blood. Slows down liver damage caused by HBV Prevention of Liver Complications : Reduces the risk of: Cirrhosis (scarring of the liver) Liver failure Hepatocellular carcinoma (liver cancer) in chronic HBV patients Entavir 0.5 mg tablet is an antiviral medication primarily used to treat chronic hepatitis B virus (HBV) infection in adults and children (aged 2+), helping to reduce the virus amount, decrease liver inflammation, and lower risks of cirrhosis or cancer. It works by inhibiting the virus from reproducing, though it is not a cure and does not prevent transmission. Key Uses and Functions : Chronic Hepatitis B Treatment: It manages long-term HBV infection in patients with both compensated and decompensated liver disease. Virus Suppression: It inhibits the viral DNA polymerase enzyme, stopping the virus from multiplying in liver cells. Liver Protection: By reducing viral load, it helps prevent further liver damage. Usage Context: It is frequently taken in combination with other antiviral drugs to improve effectiveness How It Works : Inhibits HBV DNA polymerase, an enzyme required for viral replication. Prevents HBV from multiplying inside liver cells, allowing the immune system to control infection

Generic Name: Oseltamivir phosphate (equivalent to 75 mg oseltamivir) Dosage Form: Oral hard capsule Strength: 75 mg oseltamivir per capsule Therapeutic Class: Antiviral (neuraminidase inhibitor) — systemic antiviral agent Mechanism of Action: Oseltamivir is a pro-drug that gets converted in the body to its active metabolite (oseltamivir carboxylate). It works by inhibiting influenza virus neuraminidase, an enzyme necessary for viral spread within the body, thereby reducing the severity and duration of influenza symptoms. Inactive Ingredients: Vary by manufacturer (commonly include carriers like croscarmellose sodium, gelatin, povidone, starch, and colorants). Packaging: Typically 10 capsules per strip (may vary by seller). Storage: Store at room temperature in a dry place, protected from direct sunlight. Oselvir 75 mg capsules, containing oseltamivir, are antiviral medications primarily used to treat and prevent influenza A and B (flu), including H1N1 swine flu, by stopping the virus from spreading in the body. It relieves symptoms like fever, cough, sore throat, and body aches. It is most effective when taken within 48 hours of symptom onset. Treatment of Influenza: Reduces the severity and duration of flu symptoms, often shortening the illness by about 1–2 days. Prevention (Prophylaxis): Used to prevent infection in individuals exposed to the influenza virus. Swine Flu (H1N1): Effective in treating H1N1 virus infections. OSELVIR 75 mg is an antiviral medicine used for the treatment and prevention of influenza (flu). Main Uses : Treatment of Influenza A and B (flu) Reduces severity and duration of symptoms such as fever, cough, sore throat, body aches Most effective when started within 48 hours of symptom onset Prevention (prophylaxis) of influenza After close contact with an infected person During flu outbreaks, especially in high-risk individuals How it Helps : Stops the flu virus from spreading inside the body Helps patients recover faster and reduces complications

Composition Active Ingredient: Oseltamivir Phosphate (pro-drug of oseltamivir) Strength: 75 mg oseltamivir per capsule Equivalent to approximately 98.5 mg oseltamivir phosphate in the formulation (depending on manufacturer) Dosage Form: Hard Gelatin Capsule Route: Oral administration Pharmacological Class Class: Antiviral agent — neuraminidase inhibitor Mechanism of Action: Oseltamivir is activated in the body to oseltamivir carboxylate, which inhibits the neuraminidase enzyme on influenza viruses (A and B), preventing new virions from being released from infected cells and limiting spread of the infection. Therapeutic Uses (Indications) This medicine is prescribed for: ✔ Treatment of acute, uncomplicated influenza (flu) in adults and children (when influenza virus is circulating and symptoms are present). ✔ Prevention (prophylaxis) of influenza infection after exposure in high-risk individuals (as directed by clinician). Dosage & Administration Adults & Adolescents (≥13 years): • Treatment: 75 mg twice daily for 5 days • Prophylaxis: 75 mg once daily for up to 10 days (or longer during outbreaks) Take orally, with or without food (taking with food may reduce stomach upset). Swallow capsules whole — do not chew or crush. Pediatric dosing and renal adjustments vary by weight and kidney function — follow physician instructions.
