Advances of Diphenidol in Forensic Toxicological Analysis
摘要
Abstract
Diphenidol is a non-phenothiazine anti-vertigo and anti-emetic over-the-counter drug,an analogue of trihexyphenidyl hydrochloride,and usually in the form of its hydrochloride,which was first approved in the USA in 1967.Diphenidol can improve the blood flow of cerebral vertebral artery,reduce the vertigo stimulation of vestibular nerve,inhibit the labyrinth function of inner ear,and block the vomiting center or the medullaoblongata emetic chemosensory area.Then,this drug has good anti-vertigo effect,less adverse reactions,high safety and so on,so it has been widely used in clinical practice,especially employed as an anti-emetic agent in the treatment of vomiting and vertigo associated with surgery,radiotherapy,chemotherapy,Meniere's disease,and other labyrinthine disorders.Diphenidol is generally considered a relatively safe drug,which is inexpensive and easy to purchase.However,ingesting large doses intentionally or accidentally can cause serious toxic effects.The main symptoms of diphenidol poisoning include dry mouth,irritability,hallucinations,headache,euphoria and temporary hypotension.In severe cases,respiratory failure may result from respiratory depression,hypotensive shock or arrhythmia.In recent years,there have been a number of suicides and accidental poisonings related to diphenidol in China,including preschool children being poisoned by ingestion and adults attempting suicide.In forensic practice,diphenidol poisoning can be difficult to diagnose.Additionally,clinical symptoms and signs of diphenidol poisoning vary and are easily confused with epilepsy,tetanus rabies,hysteria or rodenticide poisoning.In addition,if there are no tablets or bottles left on the scene,a definitive diagnosis of diphenidol poisoning may be overlooked by the forensic doctor.Therefore,the physicochemical properties,pharmacological and toxicological effects,metabolic pathways and products in vivo,human pharmacokinetics,zoological experiments,analysis and detection techniques and other aspects of diphenidol were described in this paper,in order to provide some theoretical references for related cases.关键词
