Ampicillin is a broad-spectrum antibiotic in the penicillin group of antibiotics. It works by interfering with the formation of the bacterial cell wall, which leads to the death of the bacteria. Ampicillin is effective against a wide range of bacteria, including Gram-positive and Gram-negative bacteria.
Ampicillin is commonly used to treat bacterial infections, such as respiratory tract infections, urinary tract infections, skin infections, and infections of the gastrointestinal tract. It is also used to prevent infections during surgical procedures and to prevent bacterial endocarditis (an infection of the heart) in people with certain heart conditions.
Ampicillin is available in various forms, including capsules, tablets, and injections. It is usually taken orally, but injections may be given in the hospital setting for more serious infections.
As with all antibiotics, the overuse or misuse of ampicillin can lead to the development of antibiotic-resistant bacteria, which can make treatment of infections more difficult. Therefore, it is important to use ampicillin only when it is necessary and as directed by a healthcare professional. It is also important to complete the full course of antibiotics as prescribed, even if the symptoms of the infection have improved.
