Indications & Uses
Osapiderm is indicated for:
Pharmacology
Posaconazole stops fungal cells from making ergosterol, which is a key part of the fungal cell membrane. It does this by inhibiting Lanosterol 14-α-demethylase, a cytochrome P-450 dependent enzyme that converts lanosterol to ergosterol in the membrane. When this enzyme is blocked, methylated sterol precursors build up and ergosterol runs low inside the cell membrane. The structure and function of the fungal cell membrane are weakened as a result.

Cautions & Contraindications

It must also not be given together with ergot alkaloids, CYP3A4 substrates, terfenadine, astemizole, cisapride, pimozide, halofantrine or quinidine. Taking them together may raise the plasma concentrations of these medicines, which can lead to QTc prolongation and, in rare cases, torsades de pointes. The HMG-CoA reductase inhibitors simvastatin, lovastatin and atorvastatin are also contraindicated with Posaconazole.
Pregnancy & Breastfeeding
Posaconazole should not be used during pregnancy unless the benefit to the mother clearly outweighs the possible risk to the fetus. If a mother is breast-feeding, she must stop once treatment with this medicine begins.
