The floating beads have been employed to make a sustained release of the drug in the stomach and to decrease the dose of the drug and hence overcome its side effects. The common benefits of the floating beads were it is easy preparation, without the need of a high temperature, and high percentage of the drug entrapment. In the present work, the Ketorolac tromethamine (KT) floating beads were prepared by extrusion congealing method utilizing calcium carbonate as a gas forming agent. The physical characters of the produced beads were investigated such as KT yield, KT loading, and entrapment efficiency of the drug. In addition, floating behavior, swelling, particle size, morphology and KT stability were also evaluated. In vitro drug release study was carried out, and the kinetics of the release was evaluated using the linear regression method. Furthermore, the in vivo analgesic effect of KT after oral administration of the selected formula of floating beads (F10) was carried out using hot plate and tail flick methods. Oral commercial KT tablets and KT solution were used for the comparison. The prepared beads remained floated for more than 8 h. The optimized formulation (F10) exhibited prolonged drug release (more than 8 h) and the drug release follows the Higuchi kinetic model, with a Fickian diffusion mechanism according to Korsmeyer-Peppas (n = 0.466). Moreover, F10 showed a sustained analgesic effect as compared to the commercial tablet. 相似文献

Inflammatory myofibroblastic tumors are known to sometimes regress spontaneously or in response to treatment with antiinflammatory drugs. We present the case of a 13-year-old boy with an inflammatory myofibroblastic tumor of the proximal duodenum, which regressed rapidly within days of an open surgical biopsy, resulting in perforation of the duodenum. Ketorolac was administered intravenously after the biopsy and is implicated as a potential cause of the rapid regression of the tumor. We discuss the surgical management of this patient and present a review of the literature. 相似文献

Ketorolac Tromethamine and Hemorrhage in Tonsillectomy: A Prospective,Randomized, Double-Blind Study
Ketorolac tromethamine (KT) is a nonsteroidal, antiinflammatory analgesic. Its nonsedating property makes it an attractive analgesic for sleep apnea patients undergoing uvulopharyngopalatoplasty, but its antiplatelet activity makes the potential for postoperative hemorrhage a concern. A prospective, randomized, double-blind study was designed to evaluate the bleeding risk of KT using adult tonsillectomy patients as the model. Patients were randomized into two groups receiving Meperidine (MP) (controls) or KT for the first post-operative day. Posttonsillectomy bleeding rates of 7% (3/43) in the MP group and 18.9% (7/37) in the KT group were demonstrated, but this difference was not statistically significant. The number of KT doses administered had no effect on the incidence of bleeding or the number of cases requiring return to the operative suite for hemostasis. Although this study did not attain statistical significance, the trend towards increased hemorrhage with KT is worrisome. This study and other reports in the literature support the manufacturer's warning that the use of KT is contraindicated in major surgery. 相似文献

Background
The effectiveness of the nonsteroidal anti-inflammatory drug ketorolac in reducing pulmonary morbidity after rib fractures remains largely unknown.Methods
A retrospective cohort study was conducted spanning January 2003 to June 2011 assessing pneumonia within 30 days and potential adverse effects of ketorolac among all patients with rib fractures who received ketorolac <4 days after injury compared with a random sample of those who did not.Results
Among 202 patients who received ketorolac and 417 who did not, ketorolac use was associated with decreased pneumonia (odds ratio, .14; 95% confidence interval, .04 to .46) and increased ventilator-free days (difference, 1.8 days; 95% confidence interval, 1.1 to 2.5) and intensive care unit–free days (difference, 2.1 days; 95% confidence interval, 1.3 to 3.0) within 30 days. The rates of acute kidney injury, gastrointestinal hemorrhage, and fracture nonunion were not different.Conclusions
Early administration of ketorolac to patients with rib fractures is associated with a decreased likelihood of pneumonia, without apparent risks. 相似文献70.

SummaryIn a randomized, single-dose, double-blind, parallel comparative trial of analgesic efficacy, 96 adult patients received either 10?mg ketorolac tromethamine or 400?mg glafenine orally the morning after surgery if they requested pain relief medication. Each patient provided a baseline pain assessment and then received the assigned medication. Patients assessed pain intensity and pain relief and reported any adverse events in interviews held 30 minutes after drug administration and then hourly for 6 hours. The demographic characteristics, baseline pain intensity, and surgical categories of the 47 patients who received ketorolac tromethamine and the 49 who received glafenine were similar. Both drugs provided prompt, sustained pain relief throughout the 6-hour observation period, and there were no statistically significant differences between the two groups in any of the efficacy measures analyzed. The global assessment recorded by patients suggested a slight clinical advantage for ketorolac tromethamine (32.6% of ‘excellent’ responses) as compared to glafenine (12.5% ‘excellent’). The differences in overall response were statistically significant (p = 0.017). Fourteen (30%) patients who received ketorolac tromethamine and 17 (35%) who received glafenine reported adverse experiences that began or seemed to worsen after administration of the study drugs. The most prominent were drowsiness and sleeping, both of which are common in post-surgical patients. 相似文献
