Hydrocortisone Base BP 93 Micro
Hydrocortisone Base BP 93 Micro is a highly purified, micronized form of hydrocortisone base compliant with British Pharmacopoeia (BP) standards. It is a white to off-white fine powder designed for enhanced solubility and bioavailability in pharmaceutical formulations. As a corticosteroid hormone analog, it exhibits potent anti-inflammatory, immunosuppressive, and anti-allergic activities. The micronized particle size (~93 microns) facilitates improved dispersion in topical, injectable, and oral dosage forms.

Miconazole Nitrate BP
Miconazole Nitrate BP is a high-purity, pharmaceutical-grade antifungal agent conforming to British Pharmacopoeia (BP) specifications. It is widely used in the formulation of topical and oral pharmaceutical products for the treatment of fungal infections caused by dermatophytes and yeasts, including Candida species. Miconazole Nitrate functions by inhibiting the biosynthesis of ergosterol, a vital component of fungal cell membranes, leading to cell death.
This white to off-white crystalline powder is highly effective and exhibits broad-spectrum antifungal and some antibacterial activity. It is commonly utilized in creams, ointments, powders, and gel formulations.
