Pheniramine (Prophenpyridamine;Tripoton) is a first-generation histamine H1 receptor antagonist, acts on the central nervous system (CNS) with sedative and hypnotic effect. Pheniramine displays antitumor effect and induces leukemia cells apoptosis. Pheniramine is also a safe and effective local anesthetic, with antipruritic effects[1][2][3][4].

In Vitro	Pheniramine inhibits CYP2D6, the specific P450-isozymes, to delay metabolic time and prolong antihistaminic effects[1]. Pheniramine inhibits Ca2+ influx into BC3H-1 cells by inhibiting histamine with an IC50 value of 1.01 mM and regulates cellular Ca2+ transmembrane action[2]. Pheniramine (0.5, 1.0 mM; 24 h) induces cell apoptosis in human T-cell acute lymphoblastic leukemia cell lines[3]. Pheniramine (1 μM-1 mM; 12-48 h) inhibits cell proliferation in a time-dependent manner and shows inhibitory concentration IC50s of 550 μM (CCRF-CEM cells) and 420 μM (Jurkat cells), respectively[3]. Apoptosis Analysis[3] Cell Line: Human T-cell acute lymphoblastic leukemia cell lines: CCRF-CEM and Jurkat ALL Concentration: 0.5, 1.0 mM Incubation Time: 24 hours Result: Induced cells apoptosis with chromatin condenses and marginalizes, and nuclear debris spreaded into the cytoplasm. Cell Viability Assay[3] Cell Line: Human T-cell acute lymphoblastic leukemia cell lines: CCRF-CEM and Jurkat ALL Concentration: 1 μM-1 mM Incubation Time: 12, 24, 48 hours Result: Inhibited cell proliferation and survival in a time- and dose-dependent manner.
In Vivo	Pheniramine (1.75 μM; i.t.) exerts local anesthesia effect and results spinal block in rats[4]. Animal Model: Sprague–Dawley rats (300-350 g; male)[4] Dosage: 0.30, 0.60, 0.90, 1.50, 1.75 μM Administration: Intrathecal injection; one time Result: Resulted the spinal block and displayed dose-dependent effect. Showed 100% blockades in motor function, proprioception, and nociception, with full recoveryduration of action about 41, 56, and 88 min, respectively, at 1.75 μM.
