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.
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.
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.
