Cef-3® 200 mg Capsule is a third-generation cephalosporin antibiotic containing Cefixime Trihydrate as the active ingredient. It is used to treat a variety of bacterial infections by inhibiting the synthesis of the bacterial cell wall, leading to cell death. Cefixime is effective against both Gram-positive and Gram-negative bacteria and is resistant to degradation by many beta-lactamase enzymes produced by bacteria. This makes it a valuable option for infections caused by resistant organisms.
