Trimethoprim BP Micronised
Trimethoprim BP Micronised is a high-purity, fine powdered form of trimethoprim, an antibiotic used primarily for its bacteriostatic properties. The micronisation process enhances its solubility and bioavailability, making it more effective in pharmaceutical formulations. Trimethoprim acts by inhibiting bacterial dihydrofolate reductase, thereby preventing bacterial DNA synthesis and growth. It is widely used alone or in combination therapies to treat a variety of bacterial infections.

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.
Chloramphenicol Palmitate Micronised
Chloramphenicol Palmitate Micronised is a micronized, lipophilic ester derivative of chloramphenicol, designed for improved solubility and bioavailability compared to the parent drug. It appears as a fine, white to off-white powder with enhanced surface area due to micronization. This antibiotic is widely used for oral formulations, particularly pediatric suspensions, due to its palatability and controlled release properties. Chloramphenicol Palmitate exhibits broad-spectrum antibacterial activity against both Gram-positive and Gram-negative bacteria. Its ester form offers better stability and reduced bitterness, making it a preferred choice in pharmaceutical preparations.
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.
Doxycycline Hyclate BP
Doxycycline Hyclate BP is a broad-spectrum, semisynthetic tetracycline-class antibiotic available as the hemihydrate salt form of doxycycline. It is widely used in pharmaceutical formulations due to its high bioavailability, broad antibacterial activity, and favorable pharmacokinetic profile. The compound exhibits bacteriostatic action by inhibiting protein synthesis in susceptible bacteria, making it effective against a wide range of Gram-positive and Gram-negative organisms as well as atypical pathogens. It is typically supplied as a fine, white to off-white crystalline powder soluble in water and suitable for oral and parenteral 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. It has a characteristic tar-like odor and is highly valued in pharmaceutical and dermatological applications for its anti-inflammatory, antiseptic, antipruritic (anti-itch), and keratolytic properties. Ichthammol penetrates deeply into the skin and soft tissues, helping to alleviate inflammation and promote healing. It is widely used in topical preparations for treating skin conditions such as eczema, psoriasis, boils, abscesses, and other dermatological infections.
Metronidazole BP
Metronidazole BP is a benzoate ester derivative of metronidazole, used primarily as an antiprotozoal and antibacterial agent. It is a prodrug that hydrolyzes in the body to release metronidazole, making it more palatable for pediatric and geriatric oral suspensions. It complies with the British Pharmacopoeia (BP) standards for purity and efficacy.
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.
