Cubicin (daptomycin) is indicated for the care of complicated skin and skin social organisation infections caused by gram-positive microorganisms. This month’s upright reviews FDA new upshot approvals and labeling changes for: Antidiabetic AgentsPrandin (repaglinide) Tablets Antidepressant AgentsPaxil CR (paroxetine HCl) Tablets Anti-infective AgentsCipro XR (ciprofloxacin) Extended-Release TabletsCleocin (clindamycin phosphate) Dairy productCubicin (daptomycin) for Solution Antipsychotic AgentsAbilify (aripiprazole) Tablets Antiviral AgentsValcyte (valganciclovir HCI) Tablets Cardiovascular AgentsLopressor (metoprolol tartrate) Medical aid & TabletsLotrel (amlodipine and benazepril HCl) Capsules Immune GlobulinGamunex (Immune Globulin Intravenous [Human], 10% by Chromatography Process) Oral ContraceptivesSeasonale (levonorgestrel/ethinyl estradiol) Tablets Discussion section 1 of 9 Jane S. 03 novembre Cipro - acinetobacter baumannii blood isolateFigure 2. (click image to zoom) Percentage of antimicrobials susceptible to A. baumannii, 1989-1998. For imipenem-cilastatin, data are from August 1990-1998. Ami = amikacin; A-S = ampicillin-sulbactam; Ceftaz = ceftazidime; Cipro = ciprofloxacin; I-C = imipenem-sulbactam; Pip = piperacillin. Presumed eradication occurred in 97% of patients receiving ampicillin-sulbactam and 100% of those treated with imipenem-cilastatin. One patient treated with ampicillin-sulbactam did not have repeat cultures and died before hospital discharge. Concomitant organisms included a variety of gram-negative and gram-positive organisms, as well as Candida sp (Figure 3). The respiratory tract was the site most frequently concomitantly infected with A. baumannii (ampicillin-sulbactam 47%, imipenem-cilastatin 72%). Other positive culture sites were wounds, urine, catheter tips, and eyes. Figure 3. (click image to zoom) Frequency/patient of concomitant organisms. Imipenem-cilastatin dosages ranged from 2-4 g/day intravenously or the renal-dosed equivalent. Fifty percent of patients received 500 mg intravenously every 6 hours, 44% received 1 g intravenously every 6 hours, and 1 patient (6%) received 500 mg intravenously every 8 hours. Ampicillin-sulbactam dosages ranged from 1 g ampicillin-0.5 g sulbactam intravenously every 6 hours (20%) to 2 g ampicillin-1 g sulbactam intravenously every 6 hours (80%), or its renal-dosed equivalent. |
