Randomized Controlled Trial Multicenter StudyEfficacy and Safety of an Intravenous Acetaminophen/Ibuprofen Fixed-dose Combination After Bunionectomy: a Randomized, Double-blind, Factorial, Placebo-controlled Trial.
Multimodal analgesia with acetaminophen and/or nonsteroidal anti-inflammatory drugs is recommended for the treatment of postoperative pain. Although oral fixed-dose combinations (FDCs) are available, parenteral administration may be clinically justified. The goal of this study was to investigate the clinical efficacy and safety of an intravenous FDC of ibuprofen and acetaminophen after bunionectomy. ⋯ The study found that repeated administration of an intravenous FDC of ibuprofen and acetaminophen provided statistically significant improvement in SPID48 over comparable doses of either monotherapy without an increase in adverse events. ClinicalTrials.gov identifier: NCT02689063.

Randomized Controlled Trial Comparative StudyPharmacokinetics and Tolerability of Budesonide/Glycopyrronium/Formoterol Fumarate Dihydrate and Glycopyrronium/Formoterol Fumarate Dihydrate Metered Dose Inhalers in Healthy Chinese Adults: A Randomized, Double-blind, Parallel-group Study.
The objective of this study was to assess pharmacokinetic (PK) and safety profiles of 2 fixed-dose combinations in development for the treatment of chronic obstructive pulmonary disease (COPD): budesonide/glycopyrronium/formoterol fumarate dihydrate metered-dose inhaler (BGF MDI; triple combination) and glycopyrronium/formoterol fumarate dihydrate (GFF MDI; dual combination). The PK and safety profiles of BGF MDI and GFF MDI were assessed for the first time in healthy Chinese adults after single and repeated (7-day) dosing. ⋯ Overall, all treatments were well tolerated and PK parameters were generally comparable to those previously reported in Western and Japanese healthy subjects, suggesting that the doses of BGF MDI and GFF MDI in development globally for COPD are also appropriate for Chinese patients with COPD. ClinicalTrials.gov identifier: NCT03075267.

Randomized Controlled TrialA Phase I, Randomized, Crossover, Open-label Study of the Pharmacokinetics of Solriamfetol (JZP-110) in Healthy Adult Subjects With and Without Food.
Solriamfetol (JZP-110), a selective dopamine and norepinephrine reuptake inhibitor with robust wake-promoting effects, is currently being evaluated for the reduction of sleepiness and improvement of wakefulness in patients with narcolepsy and obstructive sleep apnea. The purpose of this study was to evaluate the effect of food on the pharmacokinetic (PK) parameters and bioavailability of solriamfetol at the highest intended therapeutic dose in healthy adults and to characterize its renal excretion under fasting conditions. ⋯ Solriamfetol relative bioavailability was bioequivalent in the fed and fasted conditions, showing that solriamfetol can be taken without regard to meals; furthermore, tolerability was similar in both conditions. Renal excretion of unchanged drug is the primary route of elimination.

Randomized Controlled Trial Comparative StudyBioavailability of Edaravone Sublingual Tablet Versus Intravenous Infusion in Healthy Male Volunteers.
Edaravone is a free-radical scavenger. Edaravone 30mg IV has been approved for use in the treatment of acute ischemic stroke in Japan and China, and for amyotrophic lateral sclerosis in Japan and the United States. Considering the inconvenience of IV infusion in clinical practice, an oral tablet formulation of edaravone was developed but failed in 2011 due to poor bioavailability. More recently, a sublingual (SL) tablet formulation of edaravone 30mg was developed by a Good Manufacturing Practices-compliant manufacturer in China. This study explored the bioavailability of the SL tablet of edaravone and aimed to provide evidence to support decision making in future clinical development. ⋯ The bioavailability of the SL tablet of edaravone was 91.94%. Compared with IV administration, Cmax with SL administration was ∼17% lower and Tmax was statistically significantly longer. The exposure differences can be addressed by modifying the strength of the SL tablet, and then conducting a second study to demonstrate the pharmacokinetic bioavailability of the sublingually administered new strength versus IV infusion of edaravone.

Randomized Controlled Trial Multicenter StudyAnalgesic Efficacy of an Acetaminophen/Ibuprofen Fixed-dose Combination in Moderate to Severe Postoperative Dental Pain: A Randomized, Double-blind, Parallel-group, Placebo-controlled Trial.
Acute pain is a significant burden to the individual and to society. There is a clear need for a pain medication that provides improved analgesia over common analgesics, without compromising tolerability. The goal of this study was to determine the efficacy of a new fixed-dose combination of acetaminophen 975 mg and ibuprofen 292.5 mg (FDC 975/292.5) relative to acetaminophen or ibuprofen monotherapy, or placebo. ⋯ Overall, the fixed-dose combination of acetaminophen and ibuprofen provided greater and more rapid analgesia than comparable doses of either agent alone or placebo in adults after removal of impacted third molars. ClinicalTrials.gov identifier: NCT01420653.
