Ampicillin

Description:

Ampicillin is a semi-synthetic penicillin antibiotic that is primarily used to treat a variety of bacterial infections. It is effective against both Gram-positive and some Gram-negative bacteria, making it a broad-spectrum antibiotic. The chemical formula of ampicillin is C16H19N3O5S, and it features a beta-lactam ring, which is essential for its antibacterial activity. Ampicillin is typically administered orally or intravenously, depending on the severity of the infection. It is known for its stability in the presence of gastric acid, allowing for effective oral absorption. Common side effects may include gastrointestinal disturbances, allergic reactions, and, in rare cases, more severe hypersensitivity reactions. Ampicillin is often used in combination with other antibiotics to enhance its efficacy and to combat antibiotic resistance. Its use is guided by susceptibility testing, as some bacteria have developed resistance to ampicillin. Overall, ampicillin remains a valuable tool in the treatment of infections, particularly in pediatric and outpatient settings.

Ampicillin - Bio-X ™

CAS: 69-53-4

Ampicillin is a β-lactam antibiotic with a broad spectrum of activity against Gram-positive and Gram-negative bacteria. It is used in the treatment of bacterial infections, including those caused by methicillin-resistant Staphylococcus aureus (MRSA), Streptococcus pneumoniae, and Listeria monocytogenes. Ampicillin binds to penicillin-binding proteins in the bacterial cell wall by competitive inhibition. It prevents the formation of an antibiotic-inhibitor complex with the enzyme cell wall synthesis that is required for cell wall biosynthesis, inhibiting protein synthesis and cell division.
