概括
这项试点研究发现,口服四大麻 (THC) 和大麻 (CBD) 并没有显著改善基本震 (ET) 症状. 大麻素配方通常耐受良好,但在这个小型试验中没有显示出有效性.
科学领域:
- 神经学 神经学
- 药理学 药理学是指药理学的学科.
- 临床试验 临床试验
背景情况:
- 基本震 (ET) 是一种神经疾病,导致动作震,没有特定的药理疗法.
- 事证据表明,大麻可能有助于ET,但缺乏临床数据.
研究的目的:
- 在ET患者中研究四大麻素 (THC) 和大麻素 (CBD) 的口服药品级配方的耐受性,安全性和有效性.
- 为了确定短期暴露于THC/CBD是否会改善震幅度.
主要方法:
- 进行了Ib/II期双盲,安慰剂控制,交叉试验.

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids
184
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.

Parkinson's Disease: Treatment
148
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids
130
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...
