Randomized Controlled Trial Comparative StudyPharmacokinetics of extended-release versus conventional tramadol/acetaminophen fixed-dose combination tablets: an open-label, 2-treatment, multiple-dose, randomized-sequence crossover study in healthy korean male volunteers.
A fixed-dose combination tablet of tramadol/acetaminophen exhibits both rapid and sustained analgesic effects due to different pharmacologic activities. To prolong analgesia and improve patient convenience, an extended-release (ER) tablet of this agent has been developed. ⋯ The ER formulation displayed a similar AUC(0-12,ss) to that of the IR formulation for tramadol and acetaminophen.

Randomized Controlled Trial Multicenter StudyLongitudinal assessment of estimated glomerular filtration rate in apparently healthy adults: a post hoc analysis from the JUPITER study (justification for the use of statins in prevention: an intervention trial evaluating rosuvastatin).
Serum creatinine-based estimates of glomerular filtration rate (eGFR) are frequently used to identify patients with chronic kidney disease and assess cardiovascular risk both in clinical trials and in clinical practice. Although change in eGFR may be useful to assess change in renal function in patients with chronic kidney disease, the utility of serum creatinine-based eGFR is uncertain, particularly among individuals with normal or only mildly impaired renal function. ⋯ In JUPITER, reductions in MDRD or CKD-EPI eGFR levels were greater in study participants with higher baseline eGFR levels but less in the rosuvastatin than in the placebo group. Future studies are required to assess the reliability of serum creatinine-based estimates of GFR to assess change in renal function, particularly among individuals with normal serum creatinine levels.

Randomized Controlled Trial Meta Analysis Comparative StudyMultikinase inhibitors in metastatic renal cell carcinoma: indirect comparison meta-analysis.
Randomized controlled trials (RCTs) of multikinase inhibitors sunitinib, sorafenib, and pazopanib have reported efficacy compared with results from placebo and interferon-α (INF-α). To date, these drugs have not been compared in head-to-head trials. ⋯ Some multikinase inhibitors have a favorably reported PFS for patients with mRCC compared with results using IFN-α or placebo. Our findings suggest that sunitinib might offer some clinical benefit over sorafenib in terms of PFS. No statistical difference was found between sorafenib and pazopanib treatments. However, these conclusions are based on 2 indirect comparisons of single RCTs. More RCTs are required to confirm these findings and investigate the clinical effectiveness of multikinase inhibitors in the treatment of mRCC.
