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.

Carbocisteine AJI 92
Carbocisteine AJI 92 is a high-purity pharmaceutical-grade amino acid derivative, chemically known as S-carboxymethyl-L-cysteine. It is a white to off-white crystalline powder with a slightly sulfurous odor and is freely soluble in water. Carbocisteine functions primarily as a mucolytic agent—reducing the viscosity of mucus and promoting expectoration in respiratory tract infections. The "AJI 92" specification refers to its compliance with the purity standards established by Ajinomoto's amino acid quality benchmarks, ensuring it meets stringent pharmaceutical-grade quality control for active pharmaceutical ingredients (APIs). It is widely used in oral syrups, tablets, and granules in both human and veterinary medicine.
Diphenhydramine HCL BP
Diphenhydramine HCL BP is a first-generation antihistamine with potent anticholinergic, sedative, and antiemetic properties. It is commonly used to relieve symptoms associated with allergies, hay fever, the common cold, and motion sickness. Diphenhydramine HCL is a white crystalline powder, highly soluble in water, making it suitable for oral, topical, and injectable pharmaceutical formulations. Due to its ability to cross the blood-brain barrier, it causes sedation and is often used as a sleep aid and for managing Parkinson’s disease symptoms.
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.
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.
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.
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.
