Hetacillin
Hetacillin is a beta-lactam antibiotic in the penicillin family. It is a prodrug of ampicillin and is used in the treatment of various bacterial infections. Hetacillin is not commonly used today due to the availability of more effective antibiotics.
History[edit | edit source]
Hetacillin was first synthesized in the 1960s as part of a series of prodrugs designed to improve the oral bioavailability of ampicillin. The addition of a hydroxyethyl group to the ampicillin molecule resulted in a drug that was more stable in the acidic environment of the stomach, allowing for better absorption and higher blood levels of the active drug.
Pharmacology[edit | edit source]
As a prodrug, hetacillin is inactive until it is metabolized in the body. The hydroxyethyl group is cleaved off, releasing the active drug, ampicillin. Ampicillin is a broad-spectrum antibiotic that works by inhibiting the synthesis of the bacterial cell wall, leading to cell death.
Clinical Use[edit | edit source]
Hetacillin was used in the treatment of a variety of bacterial infections, including respiratory tract infections, urinary tract infections, and skin infections. However, the development of more effective and better-tolerated antibiotics has led to its decline in use.
Side Effects[edit | edit source]
Like other penicillins, hetacillin can cause a range of side effects. These can include allergic reactions, nausea, vomiting, and diarrhea. In rare cases, it can cause more serious side effects such as anaphylaxis or Clostridium difficile-associated diarrhea.
Resistance[edit | edit source]
Bacterial resistance to hetacillin can occur through several mechanisms. These include the production of beta-lactamase enzymes that can inactivate the drug, and changes in the bacterial cell wall that prevent the drug from binding.
