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.
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.
