- 遗传学 遗传学 是一个
- 代谢障碍 代谢障碍 代谢障碍
背景情况:
- 氏病 (Gaucher disease,GD) 是一种罕见的遗传疾病,需要酶替代疗法 (ERT).
- 标准ERT每两周一次 (Q2W) 进行.
- 延长间隔ERT (Q3-4W) 可能为稳定的患者带来好处.
研究的目的:
- 为了比较延长间隔 (Q3-4W) ERT与标准两周一次 (Q2W) ERT的疗效和安全性.

主要方法:
- 一个目标试验模拟,使用法国GD注册数据进行序列设计.
- 根据临床和人口统计因素,63名切换到Q3-4W ERT的患者与215名Q2W ERT患者的匹配.
- 主要结局:与GD相关的临床事件的组合;10%的非劣势差.
主要成果:
- 在 Q3-4W 和 Q2W ERT 组之间,临床事件风险没有显著差异 (HR: 0.98 [95% CI: 0.54-1.51]).
- 在整个随访期间,绝对风险差异仍然低于10%的非劣势值.
- 在Q3-4W群体中,生物标志物保持稳定或略有下降,从而大大节省了成本 (每位患者在6年内节省45万欧元).

Pharmaceutical Alternatives: Stability-Related Therapeutic Nonequivalence
233
Generic intravenous (IV) drugs are considered bioequivalent to their branded counterparts due to their 100% bioavailability upon administration. However, variations in stability among different drug products can significantly influence their therapeutic performance, even if they are pharmaceutically equivalent.Cefuroxime, a prophylactic antimicrobial, is often used as a single-dose IV injection for patients undergoing coronary artery bypass grafting surgery. A 3 g dose typically provides...

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions
315
Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...

Bioequivalence studies: Biowaivers
334
Body:In certain scenarios, in vitro dissolution tests can replace in vivo bioequivalence studies. This is particularly true when a drug product, though available in varying strengths, maintains proportional similarity in its active and inactive ingredients. In such cases, the need for in vivo bioequivalence studies for lower strength variants may be waived, provided dissolution tests and in vivo studies on the highest strength yield satisfactory results.Bioequivalence can be indicated through...

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment
316
Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

Bioequivalence: Overview
2.1K
Pharmaceutical equivalents, by definition, are drug products with the same active ingredient in the same quantities, encapsulated in identical dosage forms, and intended for the same administration routes. These pharmaceutical equivalents are deemed bioequivalent if the bioavailability of the active entity in the drug preparations is similar. Moreover, pharmaceutical equivalents demonstrating bioequivalence are also regarded as therapeutically equivalent. This means that when used as directed,...

Continuous Renal Replacement Therapy
1.4K
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...
