盐酸非那吡啶(Phenazopyridine)是一种偶氮化物药物,当服用后随着尿液排出时,能够对发炎部位镇痛,舒缓不适。其主要作用于泌尿道黏膜,起到局部止痛或麻醉的效果,并以原型形式直接从尿液中排出体外。
生物活性盐酸非那吡啶(Phenazopyridine HCl)是一种局部镇痛剂,已被广泛用于治疗泌尿系统疾病。研究表明,它能够抑制sodium channel protein type 1 subunit alpha蛋白,从而发挥其镇痛作用。

不良反应常见的不良反应包括:
较少见但严重的不良反应包括:
盐酸非那吡啶是一种淡红色至暗紫色的结晶性粉末。
用途主要用于缓解由膀胱炎、前列腺炎、尿道炎、淋病性尿道炎及内窥镜检查、尿道插管等引起的尿道和膀胱疼痛、灼热感以及尿频、尿急等症状。
Novel Schiff bases (1-4) were synthesized by the reaction of 2-hydroxybenzaldehyde, 2-hydroxy-5-methoxybenzaldehyde, 2-hydroxy-5-nitrobenzaldehyde, 2-hydroxy-1-naptaldehyde with phenazopypridine hydrochloride (PAP) and their structures were elucidated by means of spectroscopic techniques. The electrochemical reduction of PAP and its Schiff bases (1-4) were carried out on glassy carbon electrode (GCE) in dimethyl sulfoxide (DMSO) using the cyclic voltammetric (CV) technique. The effect of functional groups on reduction potential of Schiff bases was investigated. A general electrochemical reduction mechanism of the compounds was also suggested.
