Omnicef-O 100mg Tablet DT contains Cefixime, a third-generation cephalosporin antibiotic effective against a broad spectrum of bacterial infections. This formulation is designed as a dispersible tablet, facilitating ease of administration, particularly in pediatric and geriatric patients who may have difficulty swallowing conventional tablets. Cefixime exerts its bactericidal action by inhibiting bacterial cell wall synthesis, leading to cell lysis and death. Omnicef-O 100mg is indicated for the treatment of various infections caused by susceptible organisms, including uncomplicated urinary tract infections, acute otitis media, pharyngitis, tonsillitis, bronchitis, and certain types of gonorrhea. The drug demonstrates activity against common pathogens such as Streptococcus pneumoniae, Haemophilus influenzae, Escherichia coli, and Proteus mirabilis. The dispersible nature of the tablet allows rapid disintegration in the oral cavity or in a small volume of water, enhancing patient compliance and convenience. Dosage and duration of therapy should be determined based on the severity of infection, patient age, and renal function. As with all antibiotics, it is essential to complete the prescribed course to prevent resistance development. Common adverse effects may include gastrointestinal disturbances, hypersensitivity reactions, and, rarely, Clostridium difficile-associated diarrhea. Omnicef-O 100mg Tablet DT should be used under medical supervision with appropriate diagnostic evaluation.
