Silver Sulphadiazine USP
Silver Sulphadiazine USP is a topical antimicrobial agent used primarily in the treatment and prevention of infections in burn wounds and other skin injuries. It combines the broad-spectrum antibacterial effects of silver ions with the antimicrobial properties of sulphadiazine, a sulfonamide antibiotic. This combination helps to prevent bacterial colonization and promotes healing by reducing the risk of infection. Silver Sulphadiazine is widely used in clinical and hospital settings and is available as a cream or ointment formulation meeting United States Pharmacopeia (USP) standards for purity and quality.

Cetirizine Hydrochloride
Cetirizine Hydrochloride is a widely used second-generation antihistamine effective for treating allergic conditions such as allergic rhinitis, chronic urticaria, and other allergy symptoms. It is the hydrochloride salt form of cetirizine, existing as a white to off-white crystalline powder with a slightly bitter taste. Cetirizine HCl acts by selectively blocking peripheral H1 histamine receptors, thereby reducing allergic symptoms without significant sedation or central nervous system depression. It is commonly formulated into tablets, syrups, and capsules as an active pharmaceutical ingredient.
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.
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.
Ichthammol BP98
Ichthammol BP98, also known as ammonium bituminosulfonate, is a dark brown to black, viscous, sulfur-rich, semi-solid substance derived from the distillation of shale or bituminous rocks.

Neomycin Sulphate BP Oral
Neomycin Sulphate BP Oral is an aminoglycoside antibiotic derived from Streptomyces fradiae. It is used primarily for treating infections caused by susceptible aerobic gram-negative and some gram-positive bacteria. The oral form is especially utilized for intestinal antisepsis, to reduce bacterial flora before gastrointestinal surgery, or to treat hepatic encephalopathy by decreasing ammonia-producing bacteria in the gut. It is available in powder or tablet form conforming to British Pharmacopoeia (BP) standards, ensuring high purity and efficacy.
Piperazine Citrate BP
Piperazine Citrate BP is a pharmaceutical-grade anthelmintic compound used primarily for the treatment of intestinal worm infections, especially ascariasis (roundworms) and enterobiasis (pinworms).
