Ampicillin capsules belong to a class of medications called penicillin antibiotics. They are commonly used to treat bacterial infections caused by susceptible organisms. Ampicillin works by inhibiting the growth of bacteria and disrupting their cell wall synthesis, ultimately leading to bacterial cell death.

Indications:
Ampicillin capsules are indicated for the treatment of bacterial infections caused by susceptible organisms. These infections may include:
Respiratory tract infections such as pneumonia, bronchitis, and sinusitis.
Urinary tract infections including cystitis and pyelonephritis.
Gastrointestinal tract infections such as gastroenteritis and bacterial diarrhea.
Skin and soft tissue infections including cellulitis, abscesses, and wound infections.
Bacterial meningitis, although it is often used in combination with other antibiotics for this indication.

Dosage and Administration:
The dosage of ampicillin capsules varies depending on the type and severity of the infection, the patient's age, weight, renal function, and other medical conditions. It is typically taken orally, with or without food, as directed by the prescribing healthcare provider. The capsules should be swallowed whole with a full glass of water.

Precautions:
Ampicillin capsules should be used with caution in patients with a history of allergic reactions to penicillins or other beta-lactam antibiotics. Close monitoring for signs of allergic reactions, superinfections, and renal function is essential during treatment.
