概括
新的阿维巴克坦与塞夫塔齐迪姆和阿兹特雷诺姆的组合为治疗困难的格拉姆阴性细菌感染提供了希望. 这些组合对产生多个β-乳糖酶的细菌有效,包括金属β-乳糖酶.
科学领域:
- 抗微生物耐药性 抗微生物耐药性
- 药理学 药理学是指药理学的学科.
- 传染病 传染病 传染病
背景情况:
- 一种单抗克坦抗生素阿兹特雷诺姆 (Aztreonam) 由于像扩展光谱β-乳酸酶 (ESBLs) 这样的耐药性酶,对格拉姆阴性细菌失去了临床效用.
- 阿维巴克坦作为一种新的非β-乳糖β-乳糖酶抑制剂出现,有效地打击这些抵抗机制.
- 阿维巴克坦被批准与塞夫塔齐迪姆和阿兹特雷诺南结合使用,用于治疗由产生各种β-乳酸酶的细菌引起的感染.
研究的目的:
- 提供关于阿兹特里奥纳姆,阿维巴克坦及其组合的发展的历史视角.
- 审查这些抗菌剂的临床前和临床数据.
- 评估阿维巴克坦组合在治疗多药耐药格拉姆阴性感染中的临床实用性.
主要方法:
- 在MEDLINE (Ovid) 的文献搜索中查找相关研究.
- 对阿兹特雷诺和阿维巴克坦的临床前和临床数据的分析.
- 对抗微生物药物发展和耐药性模式的历史审查.
主要成果:
- 阿维巴克坦与塞夫塔齐迪姆和/或阿兹特雷诺姆的组合表明对产生多个β-乳酸酶的格拉姆阴性细菌具有有效性.
- 由于对金属β-乳糖酶水解的稳定性,阿兹特里昂胺组合表现特别有前途.
- 这些组合为以前无法治疗的感染提供了治疗选择,而aztreonam组合对青素过敏患者有利.
结论:
- 阿维巴克坦,结合塞夫塔齐迪姆和阿兹特雷诺姆,为耐多药格兰氏阴性感染提供了关键的治疗选择.
- 基于阿兹特里昂胺的组合是有价值的,因为它们对金属β-乳酸酶的稳定性和安全性.
- 其他抑制剂组合的持续开发可能会为未来的治疗方案提供替代方案.

Combined Effects of Drugs: Synergism
3.7K
Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein
209
Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

Nondepolarizing (Competitive) Neuromuscular Blockers: Pharmacokinetics
427
All neuromuscular blocking agents are injected intravenously because they are poorly absorbed from the GI tract. Rapid onset is achieved with intravenous administration, although absorption is also adequate from an intramuscular injection. Since these agents are highly ionized, they do not readily penetrate cell membranes or cross the blood-brain barrier.
Instead, they are transported by the blood to different tissues. Muscles with a greater blood supply (arteries) and blood flow receive more...

Genomic DNA in Prokaryotes
43.3K
The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the nucleoid. The chromosome is tightly wound, or supercoiled, for efficient storage. Prokaryotes also contain other circular pieces of DNA called plasmids. These plasmids are smaller than the chromosome and often carry genes that confer adaptive functions, such as antibiotic resistance.
