Guaiphenesin BP
Guaiphenesin BP is a white crystalline powder or granules with a faint characteristic odor, classified as an expectorant used primarily in pharmaceutical formulations to relieve chest congestion. It works by loosening and thinning mucus in the airways, making it easier to cough up and clear from the respiratory tract. It is widely utilized in cough syrups, tablets, and cold remedies. Recognized for its mucolytic and muscle-relaxant properties, Guaiphenesin is included in both prescription and over-the-counter medications worldwide.

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.
