Keftab is a cephalosporin antibiotic used in clinical practice. Its therapeutic purpose is to treat bacterial infections of the respiratory tract urinary tract and skin. The drug works by inhibiting bacterial cell wall synthesis. It binds to penicillin binding proteins which are enzymes required for cross linking of peptidoglycan. Cross linking provides structural strength to the bacterial cell wall and its disruption leads to cell lysis. By preventing cell wall formation Keftab results in the death of susceptible bacteria. The medication is administered orally and is absorbed from the gastrointestinal tract. Systemic distribution allows the drug to reach infection sites throughout the body.

Keftab is a trade name for the antibiotic cephalexin, a first-generation cephalosporin used to treat bacterial infections. It functions by inhibiting the synthesis of bacterial cell walls, leading to cell lysis and death. The drug binds to penicillin-binding proteins and interferes with the cross-linking of peptidoglycan strands. After oral administration Keftab is well absorbed and distributes to sites of infection where it maintains bactericidal concentrations. Its pharmacodynamic effect results in concentration-dependent killing of susceptible gram-positive and gram-negative organisms. Clinically it is employed to manage respiratory, skin, and urinary tract infections caused by organisms such as staphylococcus aureus and escherichia coli.

Keftab is an oral cephalosporin antibiotic used to treat bacterial infections. It works by inhibiting bacterial cell wall synthesis which can affect gut flora. Common side effects include nausea diarrhea and abdominal discomfort. In some cases patients may develop a skin rash or mild allergic reactions. Rarely changes in taste or liver enzyme levels have been reported. Most side effects are transient and resolve without specific intervention.

Keftab is an oral antibiotic used to treat bacterial infections. Common side effects include nausea and abdominal discomfort. Diarrhea may occur and can range from mild to more severe forms. Skin reactions such as rash or itching are reported in some patients. Headache and dizziness are less frequent but have been documented. Rarely, allergic responses like swelling or difficulty breathing can appear. Most side effects are temporary and generally resolve without intervention.
