まとめ
薬用大麻,特にテトラヒドロカンナビノール (THC) は,化学療法による周辺神経症 (CIPN) の症状を効果的に軽減します. 大量のTHCとカンナビディオール (CBD) を併用すると,痛みや日常生活や生活の質に 顕著な改善が見られました.
科学分野:
- 腫瘍学
- 神経科学
- 薬理学について
背景:
- 化学療法による周辺神経症 (CIPN) は,化学療法の投与量を制限する一般的な副作用です.
- 以前の研究では,大麻がオキシリプラチン誘発のCIPNを緩和することが示されました.
- この研究では,カンナビジオール (CBD) とテトラヒドロカンナビノール (THC) がCIPNの症状に及ぼす特定の効果を調査しています.
研究 の 目的:
- CIPNの症状の管理におけるCBDとTHCの有効性を評価する.
- CIPN患者の日常生活活動 (ADL) と生活の質 (QOL) に起する医療大麻の影響を評価する.
主な方法:
- 医療大麻提供者のデータセットから患者によって報告されたアウトカムの分析
- 751人の適格な患者を,THC高/CBD低,CBD高/THC低のグループに分類する.
- K-meansクラスタリング,ロジスティック回帰,および線形回帰を用いた統計分析により,大麻使用6ヶ月後の症状変化,ADL,およびQOLを評価した.
主要な成果:
- THC高とCBD高の2つのグループは症状の改善を報告した.
- THC濃度が高いグループでは,灼熱感と寒さ感の改善が著しく示された (p=0. 024, p=0. 008).
- ADLとQOLの改善は,THC群で有意に高かった (p=0. 029,p=0. 006),THCとCBDの投与量との間に顕著な相互作用があった (p < 0. 0001).
結論:
- 大麻はCIPNの症状を軽減するのに有意な効果を示しています.
- THCのより高い用量は,特にCBDと併用すると,CIPNの症状からより大きな救済につながります.
- 医療大麻の使用は,CIPNを患っている患者の生活の質と日常の機能を改善します.

Chemotherapy-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.

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists
259
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates...

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists
439
Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists
321
5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids
324
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...

Cancer Therapies
7.9K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
