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.
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.
Lidocaine HCL BP
Lidocaine HCL BP is a white crystalline powder or granules that are highly soluble in water. It is a local anesthetic and antiarrhythmic agent widely used in medical and dental fields. Lidocaine HCL BP acts by blocking nerve signal transmission, providing rapid and effective numbing of targeted areas. It conforms to British Pharmacopoeia (BP) standards, ensuring pharmaceutical-grade purity and consistency. It is commonly formulated into injections, topical gels, creams, and patches for pain relief and arrhythmia treatment.
Metronidazole Benzoate BP
Metronidazole Benzoate 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.

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.
Norfloxacin
Norfloxacin is a synthetic broad-spectrum fluoroquinolone antibiotic used primarily to treat bacterial infections. It works by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication, transcription, repair, and recombination, leading to bacterial cell death. Norfloxacin is effective against various Gram-negative and some Gram-positive bacteria and is commonly used in urinary tract infections, prostatitis, and gastroenteritis.
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). It works by paralyzing the worms, allowing them to be expelled naturally from the body through bowel movements. Piperazine Citrate is included in the British Pharmacopoeia (BP) and is known for its safety, efficacy, and wide use in both human and veterinary medicine.
