Semotrim Tablet

Cotrimoxazole is bactericidal in vitro to a wide range of Gram-positive and Gram-negative organisms, including Streptococcus, Staphylococcus, Pneumococcus, Neisseria, B. catarrhalis, Escherichia coli, Klebsiella, Proteus spp., Haemophilus, Salmonella, Shigella, Vibrio cholerae, Brucella, Pneumocystis carinii, Nocardia and Bordetella. A particularly high degree of activity is exhibited against Haemophilus influenzae, E. coli and Proteus spp., making Cotrimoxazole particularly suitable for the treatment of chronic bronchitis and urinary tract infections. Cotrimoxazole exerts its bactericidal action by the sequential blockade of two bacterial enzyme systems in the biosynthesis of Folinic acid in the micro-organisms. The synergy thus produced accounts for the high degree of bactericidal activity.

Indications are :

• Respiratory tract infections, including acute and chronic bronchitis (treatment and prophylaxis), bronchiectasis, lung abscess, lobar and broncho-pneumonia, Pneumocystis carinii pneumonitis, sinusitis and otitis media.
• Genito-urinary tract infections, including urethritis, acute and chronic cystitis, pyelonephritis, prostatitis and gonorrhoea.
• Gastro-intestinal tract infections, caused by Salmonella typhi and Salmonella paratyphi, including the chronic carrier state.
• Other infections, caused by a wide range of organisms confirmed to be susceptible to Cotrimoxazole and where the therapeutic benefits are considered to outweigh the possible occurrence of adverse events.
• Such infections include acute and chronic osteomyelitis, acute brucellosis, skin infections including pyoderma, abscesses and wound infections, septicaemia, bacillary dysentery and cholera (as an adjuvant to fluid and electrolyte replacement), nocardiosis and mycetoma.
