Penetration of fleroxacin and ciprofloxacin into skin blister fluid: a comparative study.

The penetration of multiple-dose concentrations of oral fleroxacin (400 mg every 24 h) and ciprofloxacin (500 mg every 12 h) into skin blister fluid in 12 healthy volunteers was determined in a randomized crossover study. Serum, blister fluid, and paper disk samples were analyzed by large-plate microbiologic assay. The mean areas under the concentration-time curve (AUC) for serum were 88.6 and 18.2 micrograms.h/ml/70 kg for fleroxacin and ciprofloxacin, respectively. The mean AUC for blister fluid and paper disks were 71.2 and 15.0 micrograms.h/ml/70 kg and 77.8 and 15.4 micrograms.h/ml/70 kg for fleroxacin and ciprofloxacin, respectively. Calculated penetration into interstitial fluid ranged from 74 to 92% for fleroxacin and 56 to 96% for ciprofloxacin; penetration was calculated by using the ratio of maximum drug concentration or AUC in blister fluid and paper disks to maximum drug concentration or AUC in serum. There was no significant difference between fleroxacin and ciprofloxacin in the percent penetration into skin blister fluid.

Pointing to the way ahead. Health education for people with learning disabilities.

People with learning disabilities have a right to health education, and nurses working with them have ample opportunities to fulfil this role. Health education must cater for individual clients' needs, and be presented in a style and language they can easily understand. Effective communication partly depends on being able to emphasize with clients; it is important to appreciate that clients are responsible for their actions.

Absorption of oral ciprofloxacin in a patient with cardiogenic shock.

Congestive heart failure and cardiogenic shock can alter the absorption process of some drugs. The absorption of ciprofloxacin has been studied in several disease states, but the effect of cardiogenic shock on its absorption is unknown. A 63-year-old man had a large myocardial infarction complicated by cardiogenic shock. When he began taking ciprofloxacin for pneumonia, he had renal and cardiac failure. Ciprofloxacin 500 mg was administered every 24 hours by nasogastric tube. Blood samples were collected 5 minutes prior to the second dose (20 hrs after the initial dose) and then regularly until 11 hours after the dose. Samples were analyzed using high-performance liquid chromatography. The trough concentration 20 hours after the initial dose was 3.7 micrograms/ml, and the serum concentrations after the second dose went from 5.6 to 4.94 micrograms/ml over the 11-hour sampling period. The peak concentration of 5.6 micrograms/ml occurred within 30 minutes after ciprofloxacin administration. It can be concluded from this case study that ciprofloxacin was adequately absorbed in this patient with multiple organ failure.

The effect of administration rate on cisplatin-induced emesis.

In an attempt to determine the influence of administration time on cisplatin-induced emesis, 20 adults previously untreated with cisplatin were enrolled into this double-blind study. Twenty patients were randomly assigned to receive high-dose cisplatin (greater than 100 mg/m2) either by a one-hour infusion or by an eight-hour infusion. All patients received antiemetic therapy with metoclopramide 2 mg/kg intravenously one-half hour before cisplatin administration, and 1 1/2, 3 1/2, 5 1/2, and 8 1/2 hours after cisplatin administration. Patients in the eight-hour infusion group experienced significantly fewer emesis episodes than did patients in the one-hour infusion group. The median of emesis episodes in the eight-hour group was one (range, 0 to 2) and in the one-hour group was three (range, 0 to 8). In patients receiving high-dose cisplatin plus metoclopramide, increasing the administration time from one hour to eight hours resulted in a small but significant decrease in emesis episodes. The cisplatin infusion rate should be considered as a variable in cisplatin-antiemetic trials.

Principles of antibiotic usage.

New antibiotics must demonstrate an advantage over older agents with respect to therapeutic efficacy, protection against infection, toxicity, cost, and pharmacokinetic properties before they can be approved for public consumption. In order to use antibiotics properly, we must know more about whether certain organisms are resistant or sensitive to the drug; it must also be determined how sensitive or resistant the bacterium is to the drug and how long serum and tissue levels remain above inhibitory or bactericidal concentrations of the drug for the suspected or proven pathogen. Cost issues and potential for adverse reactions must also be considered. In brief, to prevent or treat infections the clinician must be familiar with the microbiology, pharmacology, toxicology, and cost of antibiotics.

Comparison of concentrations of amoxicillin and ampicillin in serum and middle ear fluid of children with chronic otitis media.

Twenty-eight children aged five to nine years with chronic serous otitis media received a single dose of either ampicillin or amoxicillin by the oral route 1-2 hr before the removal of middle ear fluid by ventilation tubes inserted through the tympanic membrane. At the time middle ear fluid was obtained, a sample of blood was drawn from the patient, and levels of antibiotic in both specimens were microbiologically assayed by a disk diffusion method. Levels of amoxicillin (mean+/-standard error [SE], 1.48+/-1.6 microng/ml) in middle ear fluid were consistently and significantly higher (P less than 0.05) than levels of ampicillin (mean+/-SE, 6.2+/-5.0 microng/ml).
