Kassem, A. A. published the artcileFormulation and stabilization of antazoline hydrochloride nasal drops, Safety of N-Benzyl-N-((4,5-dihydro-1H-imidazol-2-yl)methyl)aniline hydrochloride, the publication is Bulletin of the Faculty of Pharmacy (Cairo University) (1978), 15(2), 161-76, database is CAplus.
The influence of storage and various stabilizers on the degradation of antazoline-HCl (I) [2508-72-7] nasal drops was investigated. The degradation reaction of I was 1st order with half life of 162.8 days. Addition of stabilizers increased the stability of the drug. A mixture of 20% propylene glycol [57-55-6] with 0.1% w/v Na metabisulfite was relatively better than other stabilizers tested and the half life of the drug is protracted to 1995 days.
Bulletin of the Faculty of Pharmacy (Cairo University) published new progress about 2508-72-7. 2508-72-7 belongs to imidazoles-derivatives, auxiliary class Inhibitor,Immunology/Inflammation,Histamine Receptor, name is N-Benzyl-N-((4,5-dihydro-1H-imidazol-2-yl)methyl)aniline hydrochloride, and the molecular formula is C17H20ClN3, Safety of N-Benzyl-N-((4,5-dihydro-1H-imidazol-2-yl)methyl)aniline hydrochloride.
