Vitamin B3 (Nicotinamide)
Vitamin B3 Nicotinamide, also known as Niacinamide, is a water-soluble amide form of vitamin B3. It plays a crucial role in cellular energy production and DNA repair by serving as a precursor for coenzymes NAD and NADP. Nicotinamide is preferred in many pharmaceutical and cosmetic applications due to its stability and lower side-effect profile compared to niacin. It is widely used in pharmaceuticals, nutraceuticals, cosmetics, and food fortification.

Dicyclomine Hydrochloride
Dicyclomine Hydrochloride is an anticholinergic and antispasmodic agent used primarily to relieve smooth muscle spasms in the gastrointestinal tract. It works by blocking muscarinic receptors, thereby reducing muscle contractions and spasms, which helps alleviate symptoms of irritable bowel syndrome (IBS) and other functional bowel disorders. It is commonly available in oral tablets, capsules, and injectable formulations.
Gentamycin Sulphate
Gentamycin Sulphate is an aminoglycoside antibiotic derived from Micromonospora purpurea and Micromonospora griseorubida. It appears as a white or off-white crystalline powder, highly soluble in water, with a characteristic aminoglycoside odor. Gentamycin Sulphate is widely used in human and veterinary medicine for its broad-spectrum bactericidal activity against aerobic Gram-negative and some Gram-positive bacteria. It works by inhibiting bacterial protein synthesis through binding to the 30S ribosomal subunit, leading to bacterial cell death. Due to its effectiveness against severe infections and multi-drug resistant strains, it is an essential antibiotic in clinical settings.
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.
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.
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.
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.
