LOTUSATE vs POLYSPORIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
LOTUSATE is a selective serotonin reuptake inhibitor (SSRI) that inhibits the reuptake of serotonin at the presynaptic neuronal membrane, enhancing serotonin activity in the central nervous system and thereby exerting antidepressant and anxiolytic effects.
Polysporin is a combination of polymyxin B and bacitracin. Polymyxin B disrupts bacterial cell membrane by binding to lipopolysaccharides, increasing permeability. Bacitracin inhibits bacterial cell wall synthesis by interfering with dephosphorylation of the lipid carrier in peptidoglycan synthesis.
100 mg orally twice daily, with or without food.
Apply a thin layer topically to the affected area 1 to 3 times daily. If using the ointment, cover with a sterile bandage if desired.

Terminal elimination half-life is 3.5-4.5 hours in healthy adults; prolonged to 8-10 hours in moderate hepatic impairment, requiring dose adjustment.
Polymyxin B: 6–7 hours (impaired renal function: prolonged). Bacitracin: 1.5 hours (topical; not systemically absorbed).
Primarily renal excretion of unchanged drug (65-75%) with 15-20% as glucuronide conjugate; 10-15% eliminated via feces.
Polysporin (polymyxin B/bacitracin) ophthalmic/otic/topical: Minimal systemic absorption. Renal elimination for absorbed fraction: <1% of dose.
