まとめ
パクリタキセルを投与された乳がん患者の化学療法による周辺神経症 (CIPN) の予防にメトホルミンはわずかな効果があるかもしれないが,結果は統計的に有意ではなかった. このよく耐える薬剤については,さらなる研究が必要である.
科学分野:
- 腫瘍学
- 神経学
- 薬理学について
背景:
- 化学療法による周辺神経病 (CIPN) は,特にパクリタキセルによるがん治療における重要な課題です.
- CIPNに対して有効な予防策は限られている.
- 抗糖尿病薬であるメトホルミンは,臨床前モデルで神経保護的特性を示し,CIPNの予防の可能性を示唆しています.
研究 の 目的:
- 乳がん患者におけるパクリタキセル誘発性周辺神経症 (CIPN) の予防策としてのメトホルミンの有効性を評価する.
- この患者集団におけるメトホルミンの安全性と耐性を評価する.
主な方法:
- パクリタキセル化学療法を受けた60人の乳がん患者によるランダム化比較試験.
- 患者はメトホルミン (500 mg 毎日2回) またはプラセボを投与された.
- 神経伝導研究 (NCS) と臨床評価は,外周神経機能と神経症の症状をモニターした.
主要な成果:
- CIPNの発生率はメトホルミン群で低かったが,この違いは統計的に有意ではなかった.
- 一般的にメトホルミンはよく耐えており,軽度の胃腸の副作用が報告されています.
- 神経伝導試験のパラメータ (SNAPの幅,CMAPの幅,DL) は,グループ間で有意な差異が見つかりませんでした.
結論:
- メトホルミンは,統計的に有意ではないが,CIPNの発生率を減らすために,潜在的に適度な利点を提供することができる.
- メトフォーミンの好ましい安全性プロファイルは,さらなる調査を考慮することを支持しています.
- CIPNの予防におけるメトホルミンの役割を決定的に確立するために,より大きな多センター試験が推奨されます.

Oral Hypoglycemic Agents: Biguanides and Glitazones
288
Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood...

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: 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: 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,...

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.
