概括
怀孕期间使用法莫蒂丁并没有增加先天性形风险. 然而,famotidine与更高的早产率有关,这可能是由于混因素,而不是药物本身.
科学领域:
- 产科和妇科 产科和妇科
- 药理学 药理学是指药理学的学科.
- 新生儿健康 新生儿健康
背景情况:
- 芳丁是一种组胺2-受体对手 (H2Ra),通常用于怀孕期间的胃肠道问题.
- 有限的数据存在于famotidine对胎儿结果的特定影响.
- 这项研究解决了对孕妇群体中famotidine使用的综合数据的需求.
研究的目的:
- 评估怀孕期间 famotidine 暴露与先天性形的发生率之间的关联.
- 评估famotidine对其他产科结局的影响,特别是早产.
主要方法:
- 一项观察性队列研究分析了两家日本医疗机构 (1988-2017年) 的怀孕结果数据.
- 在famotidine使用者 (n=330) 和对照组 (n=1,407) 之间进行了先天性形率的比较,这些人在妊娠的第一季度暴露于非致病性药物.
- 在整个怀孕期间,对famotidine使用者 (n=347) 和对照者 (n=1,476) 进行了分娩结果分析,包括早产,使用原始和调整的几率比率的逻辑回归.
主要成果:
- 在famotidine使用者 (3.9%) 和对照组 (2.8%) 之间没有观察到先天性形发生率的显著差异 (aOR:1.06 [95% CI:0.51-2.16]).
- 与对照组 (3.8%) 相比, famotidine 组的早产率显著更高 (8.1%). (cOR: 2.00 [95% CI:1.20-3.27]). 与对照组相比, famotidine 组的早产率明显更高 (8.1%).
- 多变量分析表明,famotidine的使用不是早产的独立风险因素,这表明存在混因素.
结论:
- 第一个三个月的famotidine暴露与先天性形的风险增加无关.
- 虽然famotidine的使用与更高的早产率相关,但这种关联可能受到混因素的影响,而不是药物本身.
- 这些发现支持在怀孕期间继续使用注射时的famotidine,并仔细考虑可能导致不良产科结果的潜在混因素.

Drugs for Peptic Ulcer Disease: Prostaglandin Analogs as Mucosal Protective Agents
355
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.
Non-steroidal anti-inflammatory drugs (NSAIDs) can induce peptic ulcers by inhibiting cyclooxygenase, decreasing...

Acid Suppressive Drugs for Peptic Ulcer Disease: Histamine H2-Receptor Antagonists
407
Histamine H2 receptors, which are intricately located on the basolateral membrane of parietal cells, play a crucial role in modulating gastric acid secretion. When released from enterochromaffin-like cells, histamine engages H2 receptors, initiating the cyclic AMP (cAMP) pathway. In this pathway, adenylyl cyclase converts ATP into cAMP, elevating intracellular cAMP levels. The activation of protein kinase A follows, stimulating the proton pump. This stimulation prompts the secretion of hydrogen...

Pharmacovigilance
774
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
In some cases, there...

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
232
Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...

Teratogenicity
2.4K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Drugs Affecting GI Tract Motility: Dopamine Receptor Antagonists
260
Prokinetic agents are specialized medications that stimulate gastrointestinal (GI) motility, promoting food movement through the GI tract. Dopamine, an inhibitory neurotransmitter, plays a significant role in this process, reducing GI motility and indirectly controlling the speed of digestion. Dopamine receptor antagonists, such as metoclopramide and domperidone, offer a unique advantage as prokinetic agents. By blocking the dopamine receptors, these drugs increase GI motility, improving food...
