Cotrimoxazole is a mixture of the sulphonamides sulphamethoxazole with trimethoprim in the proportions of 5 to 1. The two components act synergistically to produce a bactericidal or bacteriostatic action against a wide range of gram-positive and gram-negative organism and some protozoa.
Cotrimoxazole is a mixture of the sulphonamides sulphamethoxazole with trimethoprim in the proportions of 5 to 1. The two components act synergistically to produce a bactericidal or bacteriostatic action against a wide range of gram-positive and gram-negative organisms and some protozoa. It is also active against pneumocystis carinii. Sulphamethoxazole inhibits the enzyme dihydropteroate reductase, which catalyzes the reduction of folic acid to dihydrofolic acid whilst trimethoprim prevents the reduction of dihydrofolic acid to tetrahydrofolic acid by competitive inhibition of dihydrofolate reductase, thereby interfering with cell replication.
Both drugs are rapidly and almost completely absorbed from the bowel reaching peak plasma concentrations 1-4 hours after ingestion. Sulphamethoxazole is 65% and trimethoprim is 40% protein bound.

At the recommended dose side effects are rare and mild. About 75% of the untoward effects involve the skin. Exfoliative dermatitis, Stevens-Johnson syndrome and toxic epidermal necrolysis (Lyell's syndrome) are rare. Nausea and vomiting constitute the bulk gastrointestinal reactions. Diarrhoea, glossitis, and stomatitis are uncommon. Hematological reactions include various types of anemia, granulocytopenia, purpura and agranulocytosis.
Prolonged full dose treatment with sulfamethoxazole-trimethoprim combination is associated with the risk of macrocytic anaemia due to the drug’s interference in the conversion of Folic acid into Folinic acid. If this occurs, it can be reversed by giving Folinic acid. Care should be taken when giving this combination to diabetic patients receiving sulphonylurea drug for possible potentiation of action of sulphonylurea
