Cefa 4
Cefa 4 (INN) is a fourth-generation cephalosporin antibiotic marketed by Pfizer under the brand name Maxipime. Cefa 4 is a broad-spectrum injectable antibiotic with activity against both Gram-positive and Gram-negative bacteria. Cefa 4 is administered intravenously, and is available for use in both hospitalized and home health care settings.
Uses
Cefa 4 is used to treat a wide range of bacterial infections, including skin, lung, urinary tract, and abdominal infections. It is also used to treat bacterial meningitis, which is an infection of the covering of the brain and spinal cord. It is sometimes used for the treatment of infections that other antibiotics are unable to effectively treat, such as certain multi-drug resistant organisms.
Mechanism of Action
Cefa 4 belongs to a class of antibiotics called beta-lactam antibiotics. These antibiotics work by inhibiting the growth of bacteria by preventing the formation of cell wall during replication. The cell wall is the outer layer of protection that bacteria use to defend against environmental damage and to contain their contents. Cefa 4 specifically targets penicillin-binding proteins (PBPs) in bacterial cells. When PBPs are blocked, the process of bacterial cell wall formation is disturbed, which can ultimately lead to cell death.
How Long Does it Take to Work?
The time it takes for Cefa 4 to work is dependent on the type and severity of the infection being treated. Generally, improvement in symptoms can be seen in one to three days, although it may take longer for the infection to be completely eliminated.
Absorption
Cefa 4 is not well absorbed when taken orally, so it is not available in a pill form. When administered intravenously, the bioavailability of Cefa 4 is around 100%, meaning that all of the antibiotic is present in the bloodstream.
Route of Elimination
Cefa 4 is largely eliminated unchanged in the urine, but small amounts may be excreted in the bile or feces.
Dosage and Administration
Cefa 4 doses are typically determined by the patient’s weight, age, and the severity of the infection. It is available in the form of a powder or a solution that must be diluted prior to administration. The usual adult dose ranges from 2 g to 4 g daily, divided into two or three equal doses. The usual pediatric dose ranges from 30 mg/kg to 50 mg/kg daily, divided into two or three equal doses. Cefa 4 should be administered intravenously over a period of 30 minutes to 2 hours, depending on the patient and the severity of the infection.
