- 制药政策 制药政策
- 生物药物和生物类似药物
背景情况:
- 生物药物占美国制药支出的重要且不断增长的部分.
- 生物类似产品是设计成可以与原始生物药物互换的,旨在降低医疗保健成本.
- 然而,缺乏证据证明生物类似药的竞争是否有效降低了患者自付费用 (OOP).
研究的目的:
- 调查生物类似药竞争与使用生物制剂的患者的OOP支出之间的关联.
- 确定是否引入生物类似药物导致商业保险人个人减少财务负担.
主要方法:
- 一项队列研究分析了2009年至2022年从国家商业数据库 (Optum Clinformatics Data Mart) 获取的门诊病人的索赔.
- 包括65岁以下的商业保险患者,他们使用了临床医生管理的七种生物药之一.
- 两部分回归模型评估了OOP支出差异,调整了患者和临床因素相对于生物类似药的进入.
主要成果:
- 分析了来自190,364个人的170多万份索赔.
- 在生物类似药的可用性之前和之后,每年OOP成本都增加了.
- 生物类似药物进入两年后,非零的OOP支出高出12%,生物类似药物索赔更有可能具有非零的OOP成本,尽管平均成本降低了8%.
结论:
- 生物相似竞争并非始终与商业保险门诊患者的OOP成本降低有关.

Bioequivalence: Overview
1.0K
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,...

Biopharmaceutics and Pharmacokinetics: Overview
2.0K
Understanding drugs, drug products, and their performance in pharmaceutical science is pivotal. Drugs, whether simple molecules or complex compounds, are designed to interact with the body's biological systems to diagnose, treat, or prevent diseases. Drug products include various delivery systems such as tablets, capsules, injections, and inhalers. The performance of these drug products is gauged by their ability to deliver the active ingredient to the desired site of action at the...

Drug Nomenclature
1.7K
During the development of a new pharmaceutical, the manufacturer initially assigns a code name to the drug. Once approved, the drug receives a United States Adopted Name (USAN)—a generic, nonproprietary designation. Upon being listed in the United States Pharmacopeia, this nonproprietary name becomes the drug's official name. Additionally, the manufacturer assigns a proprietary name or trademark, which serves as the brand name under which the drug is marketed. It is worth noting that...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
137
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Drug Distribution: Plasma Protein Binding
5.6K
Drugs predominantly attach to plasma proteins, with only a small percentage remaining unbound. The unbound portion can be calculated as one minus the bound fraction. Acidic drugs form large, inactive complexes by reversibly binding to plasma albumin, which prevents them from diffusing across biological barriers. These drug-protein complexes act as reservoirs for the drugs. As the concentration of unbound drugs decreases, these complexes quickly dissociate to release the free drug, maintaining...

Bioavailability: Overview
2.8K
Bioavailability refers to the proportion of an unaltered drug that, after administration, enters the systemic circulation and can be distributed to the desired action site. Factors such as gastrointestinal (GI) absorption and liver biotransformation influence the bioavailability of a drug when it is administered orally. When a drug is administered intravenously, it enters the systemic circulation directly; by definition, its bioavailability is assumed to be 100%. The bioavailability of an...
