Pharmacological Class:
Antibiotic (lipoglycopeptide)
Active Ingredient(s):
Telavancin (as HCl) 250mg, 750mg; per vial; pwd for IV infusion after reconstitution and dilution; preservative-free.
Indication(s):
Complicated skin and skin structure infections due to susceptible gram (+) bacteria.
Pharmacology:
Telavancin is a synthetic derivative of vancomycin that exerts its antibacterial effect by inhibiting bacterial cell wall synthesis and disrupting the functioning of the cell membrane. It has been shown to be effective against most isolates of Staphylococcus aureus (including methicillin-resistant strains, or MRSA), Streptococcus pyogenes, S. agalactiae, S. anginosus group, E. faecalis (vancomycin-susceptible strains only).
The use of telavancin should be avoided in patients who are pregnant, unless the benefits to the patient outweighs the potential risks to the fetus (eg, skeletal malformations).
Clinical Trials:
Telavancin (10mg/kg daily) was compared to vancomycin (1g every 12 hrs) in two randomized, multinational, double-blind studies in adults with clinically documented complicated skin and skin structure infections with MRSA suspected or confirmed as the primary pathogen. Patients could receive concomitant aztreonam or metronidazole for suspected gram (–) or anaerobic infections, respectively. The all-treated efficacy (ATe) population included all patients who received any amount of study drug and were evaluated for efficacy; the clinically evaluable (CE) population included those patients in the ATe group with sufficient adherence to protocol.
Of 1794 ATe patients, 1410 were clinically evaluable. The primary efficacy endpoint for each trial was the clinical cure rate at a followup visit in the ATe and CE populations. The clinical cure rates for the ATe populations in Trial 1 and Trial 2 were 72.5% and 74.7%, respectively, for telavancin, compared with 71.6% and 74.0% for vancomycin. The clinical cure rates for telavancin in the CE populations for the two trials were 84.3% and 83.9%, respectively, compared with 82.8% and 87.7% for vancomycin. The clinical cure rate for MRSA for telavancin was 87.0% compared to 85.9% for vancomycin.

药理：
特拉万星是一个万古霉素施加合成衍生物，通过抑制细菌细胞壁的合成及其抗菌作用，破坏细胞膜的功能。它已被证明是最有效的对金黄色葡萄球菌（包括甲氧西林株，耐药株，或MRSA）的，化脓性链球菌，无乳号，第anginosus组，粪肠球菌（vancomycin易感菌株只）。
在特拉万星的使用应避免病人谁怀孕，除非对病人的好处超过了潜在的风险对胎儿（如）骨骼畸形。
临床试验：
特拉万星（10mg/kg每天）对万古霉素比较两个随机，多国，双盲研究成人与临床记录复杂性皮肤和皮肤结构怀疑葡萄球菌感染或作为主要病原体确认（1克，每12小时）。病人可以得到伴随氨曲克怀疑或甲硝唑（ - ）或厌氧菌感染，分别为。在所有治疗功效（ATE）的人口，包括所有病人谁收到任何药物的研究，数额及对疗效进行评估;在临床上可评价（行政）有足够的人口，包括遵守协议那些在吃掉组患者。
