PYOCIDIN vs TRIMETHOPRIM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Pyocidin is a bactericidal antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
Trimethoprim inhibits bacterial dihydrofolate reductase (DHFR), preventing the reduction of dihydrofolate to tetrahydrofolate, thereby inhibiting thymidine synthesis and bacterial DNA replication. It has bacteriostatic activity against susceptible organisms.
5 mg/kg intramuscular or subcutaneous every 24 hours. Max dose 300 mg per injection.
Adult: 100 mg orally twice daily or 200 mg once daily for uncomplicated UTI; for severe infections, up to 20 mg/kg/day in divided doses. IV: 10-20 mg/kg/day divided every 6-12 hours.

Clinical Note
moderateTrimethoprim + Fluconazole
Terminal elimination half-life is 2-3 hours in patients with normal renal function; extends to 12-18 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is 8-12 hours in adults with normal renal function; prolonged to 20-40 hours in severe renal impairment (CrCl <15 mL/min).
Primarily renal excretion of unchanged drug (60-70%), with 20-30% biliary excretion and minor fecal elimination (<10%).
Renal excretion: approximately 50-60% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion; about 10-20% as metabolites (conjugated and oxidized forms); biliary/fecal excretion accounts for less than 10%.
