Sulphamethoxazole BP
Sulphamethoxazole BP is a synthetic sulfonamide antibiotic widely used in human and veterinary medicine for treating bacterial infections. It acts by inhibiting bacterial synthesis of dihydrofolic acid, thereby preventing bacterial growth. It is commonly combined with trimethoprim for synergistic effects against a broad spectrum of bacteria. The British Pharmacopoeia (BP) grade guarantees pharmaceutical purity and quality, making it suitable for formulation into tablets, suspensions, and other dosage forms.

Cetirizine Dihydrochloride
Cetirizine Dihydrochloride is a second-generation antihistamine widely used to relieve allergy symptoms such as hay fever, urticaria (hives), and other allergic conditions. It is the dihydrochloride salt form of cetirizine, presenting as a white to off-white crystalline powder that is odorless or nearly odorless and slightly bitter in taste. Cetirizine Dihydrochloride acts as a selective antagonist of peripheral H1 histamine receptors, preventing the effects of histamine and thereby reducing allergic symptoms without causing significant sedation. It is a commonly prescribed active pharmaceutical ingredient (API) in oral tablets, syrups, and capsules.
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.
Diclofenac Sodium BP
Diclofenac Sodium is a nonsteroidal anti-inflammatory drug (NSAID) widely used for its potent analgesic, anti-inflammatory, and antipyretic properties. It is the sodium salt form of diclofenac, providing enhanced solubility and rapid absorption. Diclofenac Sodium BP (British Pharmacopoeia standard) ensures pharmaceutical-grade purity and compliance with stringent quality standards. It is commonly formulated in oral tablets, topical gels, injections, and ophthalmic preparations.
Enrofloxacin Hydrochloride
Enrofloxacin Hydrochloride is a broad-spectrum fluoroquinolone antibiotic used primarily in veterinary medicine. It is the hydrochloride salt of enrofloxacin, offering enhanced solubility and bioavailability. Enrofloxacin inhibits bacterial DNA gyrase and topoisomerase IV, disrupting DNA replication in Gram-negative and Gram-positive organisms as well as some Mycoplasma species. It is available as a white to off-white crystalline powder, used in injectable, oral, and topical formulations designed for livestock, companion animals, and aquatic species.
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 Acetate
Hydrocortisone Acetate is a synthetic corticosteroid ester derived from hydrocortisone (cortisol). It is a white to off-white crystalline powder, practically insoluble in water but soluble in alcohol and acetone. This compound exhibits potent anti-inflammatory, immunosuppressive, and anti-allergic properties, making it widely used in pharmaceutical and dermatological formulations. Hydrocortisone Acetate acts by modulating gene expression to reduce the production of inflammatory mediators, thereby alleviating symptoms in various inflammatory and autoimmune conditions.
Mepyramine Maleate BP
Mepyramine Maleate BP is an antihistamine drug commonly used to relieve allergic symptoms such as hay fever, urticaria, and other allergic reactions. It works by blocking histamine H1 receptors, reducing allergic responses like itching, swelling, and redness. This compound is a white or off-white crystalline powder, soluble in water and alcohol, widely used in pharmaceutical formulations including tablets, creams, and injectables.
Metronidazole BP
Metronidazole BP is a benzoate ester derivative of metronidazole, used primarily as an antiprotozoal and antibacterial agent.
