Xylometazoline hydrochloride
Xylometazoline hydrochloride (CAS: 1218-35-5), with the molecular formula C16H24N2 · HCl and a molecular weight of 280.84 g/mol, is an imidazoline derivative. It functions as an alpha-adrenergic agonist, primarily recognised for its vasoconstrictive properties. This compound is widely utilised in pharmaceutical formulations for its efficacy in nasal decongestants, helping to alleviate symptoms associated with colds, allergies, and sinusitis by reducing swelling in the nasal passages. It is a key ingredient in many over-the-counter and prescription medications.
- IUPAC
- 2-(4-tert-Butyl-2,6-dimethylbenzyl)-2-imidazoline hydrochloride

Nasal Decongestant Formulations
Xylometazoline hydrochloride is a principal active pharmaceutical ingredient in nasal sprays and drops designed to provide temporary relief from nasal congestion. Its vasoconstrictive action reduces swelling of the nasal mucosa.
Ophthalmic Preparations
In some ophthalmic solutions, it may be used for its vasoconstrictive effects to reduce redness and swelling in the eyes, though this application is less common than its nasal use.
Research and Development
As a well-characterised adrenergic agonist, it serves as a valuable tool in pharmacological research, particularly in studies related to alpha-adrenergic receptor function and neurotransmission.
