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.
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.
Diphenhydramine HCL BP
Diphenhydramine HCL BP is a first-generation antihistamine with potent anticholinergic, sedative, and antiemetic properties.
