FOAMCOAT vs SILVADENE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
FOAMCOAT is a proprietary fibrin sealant containing human fibrinogen and thrombin. When applied topically, thrombin converts fibrinogen into fibrin monomers that polymerize into a stable clot. This forms a mechanical barrier and promotes hemostasis through the final step of the coagulation cascade.
Silver sulfadiazine exerts bactericidal activity by releasing silver ions that bind to microbial DNA and proteins, inhibiting cell wall synthesis and cell division. The sulfadiazine component provides additional bacteriostatic action by competing with para-aminobenzoic acid (PABA) to inhibit dihydropteroate synthase in folic acid synthesis.
FOAMCOAT is a topical hemostatic agent; standard adult dose is 1 to 2 mL applied directly to bleeding site, repeated as needed.
Apply a thin layer (approximately 1/16 inch) of 1% cream to the affected area once or twice daily. Use a sterile gloved hand. Reapply as needed to maintain coverage.

Terminal elimination half-life is 3-4 hours in patients with normal renal function; may be prolonged in renal impairment.
The terminal elimination half-life of sulfadiazine is approximately 10-12 hours in patients with normal renal function. Silver has a very long biological half-life (weeks to months) due to tissue deposition.
Primarily renal excretion of intact drug (60-70%) with biliary/fecal elimination accounting for 20-30%.
Silver sulfadiazine applied topically results in minimal systemic absorption. The sulfadiazine component is primarily excreted renally (approximately 70% as unchanged drug and metabolites), with biliary/fecal excretion accounting for a small fraction (<10%). Silver is largely retained in tissues, not excreted.
