Largopen® 1 g Tablet contains amoxicillin, a broad-spectrum antibiotic used to treat many bacterial infections. Doctors commonly prescribe Largopen 1 g for infections of the respiratory tract, urinary tract, skin, and soft tissues.
Amoxicillin works by stopping bacterial growth. It interferes with the formation of the bacterial cell wall, which bacteria need to survive. As a result, the bacteria break down and the body can remove the infection more easily.

Doctors often prescribe Largopen 1 g tablets for conditions such as sinusitis, bronchitis, pneumonia, ear infections, and urinary tract infections. In addition, doctors may combine amoxicillin with other medicines to treat Helicobacter pylori infections linked to stomach ulcers.
Patients take Largopen 1 g Tablet orally (by mouth) exactly as a healthcare professional prescribes.
Each tablet contains:
Amoxicillin – 1 g
The tablet also includes inactive ingredients (excipients) that help maintain stability and support the tablet formulation.
Amoxicillin belongs to the penicillin class of antibiotics.
The medicine works by blocking bacterial cell wall synthesis. Specifically, it stops enzymes that bacteria use to build their protective cell wall. Consequently, the bacterial wall becomes weak and unstable.
Because of this effect:
Bacteria cannot survive
The infection stops spreading
The immune system removes the remaining bacteria
Therefore, Largopen® 1 g Tablet helps control bacterial infections effectively.

Upper respiratory tract infections such as sinusitis and tonsillitis
