背景情况:
- 2001年底,由于七价肺炎球菌联合疫苗 (PCV7) 的严重短缺,影响了34个州的免疫计划.
- 疾病控制和预防中心 (CDC) 发布了修订后的建议,对特定的儿科群体优先考虑PCV7.
- 在医疗保健实践层面上,PCV7 短缺的影响在很大程度上是未知的.
研究的目的:
- 调查公共和私营市场之间的PCV7供应差异.
- 描述医疗保健实践中PCV7短缺的性质和程度.
主要方法:
- 与12个州405家私人诊所的疫苗订购工作人员进行了半结构面试.
- 数据收集发生在2001年10月19日至11月2日之间.
- 疫苗供应被分类为"没有问题"",难以获得一致的供应"或"缺货".
主要成果:
- 51%的实践报告了公共PCV7库存,64%报告了私人PCV7库存,州差异很大.
- 在大多数研究的州,公共PCV7比私人PCV7.7更少缺货.

Pharmaceutical Alternatives: Stability-Related Therapeutic Nonequivalence
259
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...

Pharmaceutical Alternatives: Excipients and Impurities-Related Therapeutic Nonequivalence
241
Pharmaceutical products contain more than just the active drug; they also contain various excipients such as binders, solubilizers, stabilizers, preservatives, and other elements. In some cases, impurities or contaminants might be present. Traditionally, quality control in pharmaceuticals has primarily focused on the analysis of the active drug, often overlooking the impact of these additional components. The recent issue with heparin contamination by over-sulfated chondroitin sulfate, a...

Pharmaceutical Alternatives: Polymorphic Form-Related and Particle Size-Related Therapeutic Nonequivalence
226
Changes in polymorphic forms can significantly influence the bioavailability of poorly soluble drugs. Although the FDA defines pharmaceutical equivalence based on having the same active ingredient, dosage form, and route of administration, it does not automatically disqualify products with different polymorphic forms. This means two products with different polymorphs can still be deemed pharmaceutically equivalent. However, polymorphic differences can affect properties like wettability,...

Dosage Regimen: Individualization
398
Individualization in dosing regimens is the customization of medication doses for individual patients. Its necessity arises from the goal of maximizing therapeutic benefits while minimizing risks. This approach is pivotal because human responses to drugs can vary widely; what is effective for one person may be inadequate or excessive for another. Interpatient (intersubject) variability refers to differences in drug responses between individuals, while intrapatient (intrasubject) variability...

Vaccine Production
144
Vaccine production involves a sequence of upstream and downstream processes to generate a safe and effective immunological product. It begins with cultivating microorganisms, such as viruses or bacteria, to obtain antigenic material. For viral vaccines, mammalian host cells are grown in bioreactors and subsequently infected with the target virus. The virus replicates within the host cells, which are lysed to release viral particles. This lysate is then clarified through filtration or...

Vaccines
98
Vaccines are among the most effective tools in preventive medicine, designed to prepare the immune system to recognize and combat infectious agents. By introducing antigens—substances that the immune system identifies as foreign—vaccines stimulate an adaptive immune response that leads to immunological memory. This immunological memory enables the body to mount a faster and more effective response upon future exposures to the actual pathogen.Vaccines can be categorized based on the...
