Mahacef 100mg Tablet contains Cefixime, a third-generation cephalosporin antibiotic, at a dosage of 100mg per tablet. It is indicated for the treatment of a variety of bacterial infections caused by susceptible organisms, including respiratory tract infections such as bronchitis and pneumonia, urinary tract infections, otitis media, pharyngitis, and gonorrhea. Cefixime exerts its bactericidal action by inhibiting bacterial cell wall synthesis, leading to cell lysis and death. The drug demonstrates broad-spectrum activity against Gram-positive and Gram-negative bacteria, making it effective against pathogens such as Streptococcus pneumoniae, Haemophilus influenzae, Escherichia coli, and Proteus species. Mahacef 100mg is administered orally, with the dosage and duration tailored according to the severity and type of infection, as well as patient-specific factors including age and renal function. It is generally well tolerated; however, adverse effects may include gastrointestinal disturbances such as diarrhea, nausea, and abdominal pain, as well as hypersensitivity reactions in susceptible individuals. Caution is advised in patients with a history of cephalosporin or penicillin allergy. Proper adherence to prescribed regimens and completion of the full course of therapy are essential to prevent resistance development and ensure clinical efficacy.
