Loperamide HCL
Loperamide HCL is a synthetic opioid-receptor agonist used primarily as an antidiarrheal medication. It acts on the µ-opioid receptors in the intestinal wall to decrease gut motility, prolonging transit time and allowing increased absorption of fluids and electrolytes. Loperamide HCL is widely used in pharmaceutical formulations to treat acute and chronic diarrhea, including travelers’ diarrhea and diarrhea associated with inflammatory bowel disease. It is a white to off-white crystalline powder, highly soluble in water and commonly supplied in pharmaceutical grade for oral dosage forms.
Loperamide HCL
Primary Uses
- Pharmaceutical Industry
- Active pharmaceutical ingredient (API) in antidiarrheal medications for humans and veterinary use.
- Used in over-the-counter and prescription drug formulations to control symptoms of diarrhea by slowing intestinal motility.
- Incorporated into capsules, tablets, and liquid oral suspensions for easy administration.
- Veterinary Medicine
- Used to manage diarrhea in livestock and pets, improving hydration and nutrient absorption during digestive upset.
Secondary Uses
- Research and Development
- Utilized in pharmacological research studying opioid receptor activity and gastrointestinal motility.
- Used in experimental models for evaluating antidiarrheal compounds and intestinal physiology.
- Formulation Studies
- Employed in formulation optimization for controlled-release and combination products targeting gastrointestinal disorders.

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.
