Randomized Controlled Trial Comparative Study
Analgesic efficacy of quick-release versus standard lornoxicam for pain after third molar surgery: a randomized, double-blind, placebo-controlled, single-dose trial.
The aim of this study was to evaluate the analgesic efficacy and time to onset of effect of the lornoxicam quick-release (LNX-QR) tablet compared with the standard-release tablet (LNX-ST). ⋯ LNX-QR provided a faster onset and superior analgesic effect against pain following third molar surgery than LNX-ST.

Multicenter Study Controlled Clinical Trial
Pharmacokinetics, safety and tolerance of voriconazole in renally impaired subjects: two prospective, multicentre, open-label, parallel-group volunteer studies.
Since little is known regarding the pharmacokinetics of voriconazole in renally impaired patients, two prospective, open-label, parallel-group volunteer studies were conducted to estimate the effect of renal impairment on the pharmacokinetics of oral voriconazole and intravenous voriconazole solubilized with sulphobutylether-beta-cyclodextrin (SBECD), respectively. ⋯ These data suggest that renal impairment does not affect the pharmacokinetics of voriconazole. Furthermore, in subjects with moderate renal impairment, there is a strong linear correlation between SBECD clearance and creatinine clearance, and elevated SBECD levels do not necessarily correlate with increased serum creatinine levels (an indicator of worsening renal function).

In the recent X-ACT (Xeloda in Adjuvant Colon cancer Therapy) trial, oral capecitabine (Xeloda) demonstrated superior efficacy and an improved safety profile compared with infused fluorouracil + leucovorin (folinic acid) [FU+LV] in patients with Dukes' C colorectal cancer. We used the X-ACT results to determine the cost effectiveness of capecitabine compared with FU+LV from the perspective of the Italian National Health Service (NHS). ⋯ Adjuvant capecitabine for patients with Dukes' C colon cancer has the same activity in terms of outcome when compared with FU+LV but is a lower cost option from the economic perspective of the Italian NHS.

Comparative Study
Cost-effectiveness analysis of a lidocaine 5% medicated plaster compared with gabapentin and pregabalin for treating postherpetic neuralgia: a german perspective.
This study set out to assess the cost effectiveness of using a 5% lidocaine (lignocaine) medicated plaster for the treatment of postherpetic neuralgia (PHN) compared with gabapentin, pregabalin 300 mg/day or 600 mg/day in German primary care. The analysis took the perspective of the Statutory Health Insurance scheme (GKV). ⋯ The 5% lidocaine-medicated plaster is a cost-effective treatment option for the management of PHN in Germany compared with gabapentin and both 300 and 600 mg/day of pregabalin.

NSAIDs and cyclo-oxgenase (COX)-2-selective inhibitors have been associated with gastrointestinal (GI) complications among the elderly. It is recommended that gastroprotective drugs (i.e. misoprostol, proton pump inhibitors or high doses of histamine H2 receptor antagonists) be taken concomitantly to prevent NSAID-induced GI complications among older people. However, there are concerns that the rate of concomitant use of gastroprotective drugs in elderly NSAID users is too low. This study aimed to investigate the extent to which elderly users of NSAIDs/COX-2-selective inhibitors are concurrently taking gastroprotective drugs, and to determine the factors associated with concomitant use of gastroprotective drugs and NSAIDs/COX-2-selective inhibitors in a nationwide population of older people. ⋯ Our results indicate that gastroprotective drugs are not prescribed to elderly NSAID users according to guidelines. Furthermore, COX-2-selective inhibitors were used with gastroprotective drugs more often than were traditional NSAIDs. Greater awareness of factors contributing to NSAID/COX-2-selective inhibitor-induced GI complications is warranted, particularly with respect to advanced age and concurrent use of anticoagulants.
