antihistamine drug

Astemizole (Laridal) 是一种长效、非镇静抗组胺药，用于治疗季节性过敏性鼻炎、哮喘、过敏性结膜炎和慢性特发性荨麻疹。它是组胺 H1 受体的拮抗剂，IC50值为 4 nM，还阻断 hERG K+通道，IC50值为 0.9 nM，具有抗胆碱能和止痒作用。

Fexofenadine (Carboxyterfenadine) 是一种抗组胺药物，用于治疗过敏症状，如鼻塞、花粉热和荨麻疹。与第一代抗组胺药相比，它通过血脑屏障并引起镇静的能力较差。

Diphenhydramine (Syntedril) 是第一代具有抗胆碱能作用的H1 受体拮抗剂，它能透过血脑屏障。

Piperoxan hydrochloride (Benodaine hydrochloride) 是第一代抗组胺剂，是一种 α2肾上腺素受体拮抗剂。

Oxetorone fumarate is a serotonin antagonist, antihistamine, and alpha-blocker. It was used as an antimigraine drug.

Talastine is an antihistamine drug.

Fenethazine is an effective antihistamine used as an antiallergic drug.

Phenindamine Tartrate is an antihistamine and anticholinergic drug closely related to cyproheptadine. It is used to treat symptoms of the common cold and allergies, such as sneezing, itching, rashes, and hives.

Thonzylamine (neohetramine) 是可口服的H1组胺受体拮抗剂，具有抗组胺和抗过敏特性，可用于鼻充血、过敏性结膜炎和其他过敏性疾病的研究。

Latrepirdine dihydrochloride (Dimebolin dihydrochloride) 是一种具有口服活性和神经活性的多种药物靶点的拮抗剂，可刺激淀粉样前体蛋白分解代谢和 β-淀粉样蛋白分泌。

Cinnarizine clofibrate is a calcium channel protein inhibitor as well as an antihistamine channel blocker. The compound is a drug derivative of piperazine. Cinnarizine is used for the control of vomiting due to motion sickness. It acts by interfering with the signal transmission between vestibular apparatus of the inner ear and the vomiting centre of the hypothalamus

Thenalidine is an antihistamine with anticholinergic properties used as an antipruritic drug. It was withdrawn from the US, Canadian, and UK markets due to a risk of neutropenia. Thenalidine is an antagonist of the H1-receptor.

Clemizole sulfate is a drug in clinical development for the treatment of hepatitis C virus (HCV) infection. Clemizole is a novel inhibitor of TRPC5 channels. Clemizole is an H1 antagonist. Clemizole, an antihistamine drug that was once widely used for treatment of allergic disease, was recently discovered to be a potent inhibitor (IC50, 24 nM) of the interaction between an HCV protein (NS4B) and HCV RNA. Although clemizole was widely used during the 1950s and 1960s, this was before contemporary regulatory requirements were established for new drug development, and there is very minimal information about its pharmacokinetics and metabolism.

Tofenacin (free base) is an antidepressant drug with a tricyclic-like structure. It acts as a serotonin-norepinephrine reuptake inhibitor, and based on its close relation to orphenadrine, may also possess anticholinergic and antihistamine properties. Tofenacin is also the major active metabolite of orphenadrine and likely plays a role in its beneficial effects against depressive symptoms seen in Parkinson's disease patients.
