概括
同时使用质子抑制剂 (PPI) 在接受palbociclib的转移性乳腺癌 (mBC) 患者的无进展生存期 (PFS) 显著降低,特别是在一线设置中. 需要对个人保护药物进行进一步的研究.
科学领域:
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 激素受体阳性和HER2阴性转移性乳腺癌 (mBC) 是一个重大的临床挑战.
- 帕尔博西克利布 (Palbociclib) 是一种关键疗法,但其疗效可能会受到并发药物的影响.
- 质子抑制剂 (PPI) 通常用于胃肠道保护.
研究的目的:

- 为了比较在第一线和随后的治疗环境中接受palbociclib,并无同时服用PPI的患者之间的PFS.
主要方法:
- 一项回顾性观察性研究包括165名ER+,HER2-mBC符合palbociclib治疗条件的ER+患者.
- 患者根据PPI使用情况进行分类:并发 (≥2/3的palbociclib持续时间) 或没有并发的PPI.
- 在两组之间分析了无进展生存期 (PFS).
主要成果:
- 在一线设置中,同时使用PPI与PFS显著较短 (8.88个月) 与不使用PPI (67.81个月) 相比 (p < 0.0001).
- 在二线或随后的设置中,同时使用PPI的患者的PFS为7.46个月,而没有PPI的PFS为17.29个月 (p = 0.122).
- 观察到PPI对PFS的显著负面影响,特别是在使用palbociclib.mBC的第一线治疗中.

Acid Suppressive Drugs for Peptic Ulcer Disease: Proton Pump Inhibitors
364
Peptic ulcers, often induced by H. pylori infections or NSAID usage, arise from disruptions in the delicate balance of gastric acid production. Peptic ulcers stem from heightened gastric acid levels due to H. pylori infections or NSAID use. The protective mucus layer diminishes in the presence of these factors, allowing gastric acid to erode the stomach lining and form ulcers.

Inhibition of Cdk Activity
4.7K
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Drugs for Treatment of Constipation-Predominant IBS
151
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists
187
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,...

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors
505
Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.

Drugs for Peptic Ulcer Disease: Prostaglandin Analogs as Mucosal Protective Agents
384
The gastric mucosa produces prostaglandins E2 (PGE2) and prostacyclin (PGI2), crucial in maintaining gastric health. They exert cytoprotective effects, including increasing bicarbonate secretion, releasing protective mucin, reducing gastric acid output, and preventing harmful vasoconstriction. These effects are mediated through various receptors, such as EP1, EP2, EP3, and EP4.
