HEAD & SHOULDERS CONDITIONER vs MYCOSTATIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Not applicable; this is a cosmetic conditioner. No pharmacological mechanism.
Mycostatin (nystatin) is a polyene antifungal antibiotic that binds to ergosterol in the fungal cell membrane, forming pores that increase membrane permeability, leading to leakage of intracellular contents and cell death.
Not applicable. Head & Shoulders Conditioner is a cosmetic product for external use on hair and scalp; no systemic dosing.
Nystatin suspension: 400,000-600,000 units (4-6 mL) orally four times daily for 7-14 days. Nystatin pastilles: 200,000-400,000 units (1-2 pastilles) orally four to five times daily for 7-14 days.

Not applicable for systemic elimination; local retention on hair/scalp lasts until next wash (typically 24-48 hours).
Not applicable (nystatin is not absorbed systemically; no meaningful plasma half-life exists). For reference, if absorbed, the terminal half-life would be approximately 4-6 hours, but this is not clinically relevant.
Renal (urine): <1% unchanged; biliary/fecal: <1% as parent compound; majority remains on hair/scalp and is removed via washing and shedding. Systemic absorption negligible.
Nystatin is not absorbed from the gastrointestinal tract, skin, or mucous membranes. After oral administration, virtually all of the drug is excreted unchanged in feces. Renal excretion is negligible (<0.1%).
