ampicilina

Ampicillin is a broad-spectrum antibiotic belonging to the penicillin class. It is derived from the basic penicillin structure and has been modified to resist the action of beta-lactamase enzymes produced by some bacteria. Ampicillin is effective against a variety of Gram-positive and Gram-negative bacteria, although resistance has become increasingly common.

It functions by inhibiting the synthesis of bacterial cell walls, specifically by binding to penicillin-binding proteins (PBPs). This disrupts the peptidoglycan layer, leading to cell lysis and death. Ampicillin is administered orally or intravenously. It is used to treat infections such as respiratory tract infections, urinary tract infections, skin infections, and meningitis, among others.

Common side effects of ampicillin include gastrointestinal upset, such as nausea, vomiting, and diarrhea. Allergic reactions, including rash and anaphylaxis, can also occur. It is important to complete the full course of ampicillin as prescribed by a healthcare professional to ensure eradication of the infection and to minimize the development of antibiotic resistance. Ampicillin is often combined with other drugs, such as sulbactam, to extend its spectrum of activity against bacteria that produce beta-lactamase enzymes.
