Broad spectrum antibitoic.
Septazole is bactericidal chemotherapeutic ageint with a wide spectrum comparable with that of ampicillin, chloramphenicol and tetracycline.
The constituents of Septazole have a sequential effect on the conversion of folic acid to its biologically active form, tetrahydrochloric acid. Sulphamethoxazole inhibits the enzyme dihydropteroate reductase, which catalyses the reduction of folic acid to dihydrofolic acid, whilst trimethoprim prevents the reduction of dihydrofolic acid to tetrahydrofolate by competitive inhibition of dihydroreductase. About 85% of ingested Sulphamethoxazole is absorbed, while trimethoprim is completely absorbed. Mean plasma half life of sulphamethoxazole is 9 hours, while that of trimethoprim is 10 hours.
Sulphamethoxazole has good distribution, penetrating the brain, prostate, lungs, CSF, aqueous humor. It is 66% bound to plasma proteins.
Both sulphamethoxazole and trimethoprim are excreted in the breast milk and cross the placenta and eliminated in the urine.
