Cetirizine Dihydrochloride (Cetirizine Di-HCl)
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 HCl)
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.
Chlorpheniramine Maleate
Chlorpheniramine Maleate is a first-generation alkylamine antihistamine used primarily to relieve allergy symptoms by blocking H1 histamine receptors. It appears as a white or off-white crystalline powder, freely soluble in water and alcohol. Known for rapid onset and moderate duration of action, it’s widely formulated in pharmaceuticals. It also exhibits mild anticholinergic and sedative effects.
Cyproheptadine HCL
Cyproheptadine Hydrochloride (HCL) is a synthetic first-generation antihistamine with additional anticholinergic and serotonin antagonist properties. It appears as a white to off-white crystalline powder, soluble in water, with a bitter taste. Cyproheptadine HCL is widely used in medical and veterinary fields for its potent antihistaminic effects, appetite stimulation, and treatment of allergic conditions. It blocks H1 histamine receptors, helping to reduce symptoms of allergic reactions, and is also used for various off-label applications including migraine prophylaxis and serotonin syndrome management.
Tripolidine HCL BP
Tripolidine Hydrochloride BP is a high-purity pharmaceutical-grade antihistamine used primarily to treat allergic conditions. It acts as a selective H1 histamine receptor antagonist, helping to relieve symptoms such as itching, sneezing, nasal congestion, and hives by blocking the action of histamine. The British Pharmacopoeia (BP) grade ensures compliance with stringent quality standards required for medicinal use. Tripolidine HCL is commonly formulated into tablets and syrups for effective allergy management.
