概括
大麻 (CBD) 可能没有内在的抗或镇静作用. 它的治疗效益可能来自与其他抗发作药物 (如克洛巴赞) 的相互作用,而不是直接作用.
科学领域:
- 神经科学
- 药理学
背景情况:
- 大麻 (CBD) 是一种已批准用于特定症的辅助治疗方法.
- 它的临床效果可能会受到与同时使用的抗发作药物 (ASM) 的相互作用的影响,例如克洛巴赞.
研究的目的:
- 研究大麻素 (CBD) 的内在抗和镇静性.
- 区分CBD的直接影响与药物动力学相互作用.
主要方法:
- 一个随机的,双盲的,安慰剂控制的,涉及25名健康男性的三方交叉试验.
- 单次口服剂量: 30mg CBD,700mg CBD或安慰剂.
- 通过TMS-EMG/EEG评估皮质刺激性和使用中枢神经系统测试电池的镇静性.
主要成果:
- 与安慰剂相比,CBD对TMS- EMG参数没有显著影响.
- 对于30mg和700mg的CBD剂量,在特定时间点观察到对TMS-EEG脉冲的一些影响.
- 没有发现CBD具有显著的镇静作用.
结论:
- 大麻 (CBD) 可能缺乏固有的抗和镇静性质.

326
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...

01:21Chemotherapy-Induced Nausea and Vomiting: Cannabinoids
366
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
