CETAMIDE vs SOSOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CETAMIDE is an antimicrobial combination of sulfadiazine (a sulfonamide) and trimethoprim. Sulfonamides inhibit dihydropteroate synthase, blocking folate synthesis; trimethoprim inhibits dihydrofolate reductase, producing sequential blockade of folic acid metabolism.
Selective beta-1 adrenergic receptor antagonist; reduces myocardial oxygen demand by decreasing heart rate, contractility, and blood pressure.
500 mg orally every 6 hours; maximum 4 g per day.

6-8 hours; prolonged (up to 30 hours) in severe renal impairment (CrCl <30 mL/min).
Clinical Note
moderateSulfacetamide + Mecamylamine
"The risk or severity of adverse effects can be increased when Sulfacetamide is combined with Mecamylamine."
