Detailed Explanation of Three APIs: Naphazoline Hydrochloride (550-99-2), Homatropine Hydrobromide (51-56-9), Citicoline (987-78-0) | High-Quality API Supply
High-quality active pharmaceutical ingredients (APIs) are the core of pharmaceutical preparation R&D and production. This article focuses on three clinically essential APIs with authoritative CAS numbers, helping pharmaceutical companies and research institutions quickly select products and conduct efficient procurement.
1. Naphazoline Hydrochloride
CAS Number: 550-99-2
Basic Product Information
A sympathomimetic alpha-receptor agonist, also known as Naphazoline, it appears as a white crystalline powder, freely soluble in water and ethanol. It is a commonly used vasoconstrictor API for otolaryngology and ophthalmology, featuring fast onset and mild efficacy.
Core Application Scenarios
-
Nasal Medications: Constricts nasal mucosa blood vessels to relieve nasal congestion and edema caused by allergic rhinitis, acute and chronic rhinitis, and sinusitis.
-
Ophthalmic Medications: Eliminates redness in the eyes, used in the preparation of eye drops for eye fatigue, conjunctivitis and other conditions to soothe eye discomfort.
2. Homatropine Hydrobromide
CAS Number: 51-56-9
Basic Product Information
A synthetic anticholinergic agent and muscarinic receptor antagonist, it appears as a colorless or white crystalline powder, freely soluble in water. It has mild mydriatic and cycloplegic effects, with a fast onset and short recovery cycle, making it a dedicated ophthalmic API.
Core Application Scenarios
-
Ophthalmic Examinations: Used for optometry and fundus examinations in adolescents, with recovery within 1-2 days and far fewer adverse reactions than atropine.
-
Surgical Assistance: Preoperative mydriasis preparation and glaucoma provocation tests, serving as an alternative for patients allergic to atropine.
3. Citicoline
CAS Number: 987-78-0 (Citicoline Sodium: 33818-15-4)
Basic Product Information
A nucleoside derivative nerve repair API, it appears as a white crystalline powder, freely soluble in water. As a key precursor for lecithin synthesis, it repairs nerve cell membranes and improves cerebral metabolism.
Core Application Scenarios
-
Cranial Brain Injury Repair: Used in preparations for traumatic brain injury, postoperative disturbance of consciousness, cerebral thrombosis and other conditions to accelerate cerebral function recovery.
-
Neurological Disease Treatment: Improves stroke sequelae and cerebral insufficiency, and assists in relieving cognitive impairment and neurological tinnitus.
