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.

Chloramphenicol Palmitate Micronised

Chloramphenicol Palmitate Micronised is a micronized, lipophilic ester derivative of chloramphenicol, designed for improved solubility and bioavailability compared to the parent drug. It appears as a fine, white to off-white powder with enhanced surface area due to micronization. This antibiotic is widely used for oral formulations, particularly pediatric suspensions, due to its palatability and controlled release properties. Chloramphenicol Palmitate exhibits broad-spectrum antibacterial activity against both Gram-positive and Gram-negative bacteria. Its ester form offers better stability and reduced bitterness, making it a preferred choice in pharmaceutical preparations.
