まとめ
この研究では 100種類以上の処方薬が 妊娠の最初の3ヶ月間に安全であることが判明し 妊婦には安心感を与えます しかし,クロピドグレルとリラグルチドの潜在的なリスクは特定され,さらなる調査が必要となった.
科学分野:
- 産婦人科
- 臨床薬理学
- 公衆衛生
背景:
- 妊娠中の薬物使用は胎児に害を及ぼす可能性があるため,困難です.
- タリドマイドの悲劇のような 歴史的な懸念は,安全性データの必要性を強調しています.
- 妊婦に処方された薬のアドバイスをするには 正確な情報が不可欠です
研究 の 目的:
- 最初の3ヶ月間の処方薬による重大な先天性異常のリスクを評価する.
- 妊婦の薬物使用に関する根拠に基づいたガイドラインを提供すること.
主な方法:
- デンマークにおける人口ベースのコホート研究 (2004年−2017年)
- 生産と薬物曝露に関する包括的なデータを得るためのリンクされた国家保健登録簿
- 曝露と非曝露の乳児のアウトカムを比較するためのロジスティック回帰分析
主要な成果:
- 100種類以上の薬は 重大な先天性欠陥のリスクを増加させなかった.
- 31薬はリスク増加と関連していた (調整されたオッズ比率 (aOR) ≥2. 0).
- インスリンは,全体的な不形成症に対するaOR ≥2. 0の1000人の女性に処方された唯一の薬でした.
結論:
- 大量のデータは,最初の3ヶ月間の薬物曝露と主要な先天性異常との間の100以上の無関連性を確認しています.

01:07Teratogenicity
2.7K
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...

989
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...

01:25Drug Regulation
1.8K
Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...

5.1K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

01:21Factors Affecting Drug Response: Overview
2.4K
When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...
