Clometocillin (also known as clometacillin) is a beta-lactam antibiotic belonging to the penicillin class. It is used to treat a variety of bacterial infections by inhibiting the synthesis of the bacterial cell wall.

Mechanism of Action

Clometocillin works by binding to penicillin-binding proteins (PBPs) located inside the bacterial cell wall. This binding inhibits the final transpeptidation step of peptidoglycan synthesis, which is essential for bacterial cell wall integrity. As a result, the bacteria undergo cell lysis and die.

Pharmacokinetics

Clometocillin is administered orally and is absorbed in the gastrointestinal tract. It is distributed throughout the body and achieves therapeutic concentrations in various tissues and fluids. The drug is primarily excreted unchanged in the urine.

Clinical Uses

Clometocillin is indicated for the treatment of infections caused by susceptible strains of bacteria, including:

• Streptococcus pneumoniae
• Staphylococcus aureus
• Haemophilus influenzae

It is often used in the treatment of respiratory tract infections, skin and soft tissue infections, and urinary tract infections.

Side Effects

Common side effects of clometocillin include:

• Gastrointestinal disturbances such as nausea and diarrhea
• Allergic reactions, including rash and anaphylaxis
• Hematological effects such as leukopenia and thrombocytopenia

Resistance

Bacterial resistance to clometocillin can occur through the production of beta-lactamase enzymes, which hydrolyze the beta-lactam ring, rendering the antibiotic ineffective. Resistance can also arise from alterations in PBPs, reducing the drug's binding affinity.
