Randomized Controlled TrialPharmacokinetic properties and tolerability of low-dose SoluMatrix diclofenac.
This study compared the pharmacokinetic properties and safety profile of low-dose (18- and 35-mg) diclofenac capsules manufactured using SoluMatrix Fine Particle Technology (Trademark of iCeutica Inc. (Philadelphia, Pennsylvania), and the technology is licensed to Iroko Pharmaceuticals, LLC (Philadelphia, Pennsylvania) for exclusive use in NSAIDs), which produces submicron-sized drug particles with enhanced dissolution properties, to those of diclofenac potassium immediate-release (IR) 50-mg tablets. ⋯ The pharmacokinetic properties of low-dose SoluMatrix diclofenac capsules in the healthy volunteers in this study suggest rapid diclofenac absorption as measured by T(max). Low-dose SoluMatrix diclofenac capsules represent a potential option for the management of acute and osteoarthritis-related pain.

Multicenter StudyThe shortened infusion time of intravenous ibuprofen part 1: a multicenter, open-label, surveillance trial to evaluate safety and efficacy.
The main purpose of the study was to determine the safety profile and efficacy of intravenous ibuprofen administered over 5 to 10 minutes for the treatment of pain or fever in hospitalized patients. Current evidence supports the use of intravenous infusions of ibuprofen to control pain and reduce the opioid requirements associated with surgical pain. Current dosing guidelines recommend that the drug be administered over 30 minutes. However, a more rapid infusion might yield additional benefits. The safety profile and efficacy of a shortened infusion time requires additional study. ⋯ The study demonstrates that more rapid administration of intravenous ibuprofen is well tolerated and supports intravenous ibuprofen as an effective treatment for pain and fever in hospitalized patients.

Multicenter StudyThe shortened infusion time of intravenous ibuprofen, part 2: a multicenter, open-label, surgical surveillance trial to evaluate safety.
The literature and clinical data support the use of intravenous (IV) infusions of ibuprofen to control pain and reduce the opioid requirements associated with surgical pain. According to current guidelines, IV ibuprofen can be administered via a slow IV infusion performed during a 30-minute period. Although recent studies indicate that more rapid infusions may yield additional benefits for patients, the safety of such an approach needs further evaluation. The main purpose of this study was to determine the safety of single and multiple doses of IV ibuprofen (800 mg) administered over 5 to 10 minutes at the induction of anesthesia and after the surgical procedure for the treatment of postoperative pain. ⋯ Our study found that IV ibuprofen infused over 5 to 10 minutes at induction of anesthesia is a safe administration option for surgical patients. ClinicalTrials.gov identifier: NCT01334957.

Randomized Controlled TrialAn assessment of the pharmacokinetics of a sustained-release formulation of a tramadol/acetaminophen combination in healthy subjects.
To provide consistent pain relief and improve convenient sustained release (SR), a fixed-dose combination tramadol/acetaminophen tablet was formulated. This study aimed to evaluate the pharmacokinetic profiles of an SR 75-mg tramadol/650-mg acetaminophen formulation after a single dose compared with an immediate release (IR) 37.5-mg tramadol/325-mg acetaminophen formulation after 2 doses and at steady state and to assess the effect of food on the pharmacokinetic SR formulation profile after a single dose. ⋯ The SR combination tramadol/acetaminophen tablet exhibited similar exposure and absorption rates compared with those of the IR formulation of tramadol, O-desmethyltramadol, and acetaminophen. The SR formulation may be more convenient for patients and has the potential to enhance compliance and pain control. ClinicalTrials.gov identifier: NCT01880125.

Randomized Controlled TrialGabapentin enacarbil and morphine administered in combination versus alone: a double-blind, randomized, pharmacokinetic, and tolerability comparison.
Coadministration of morphine with oral gabapentin has been shown to increase plasma gabapentin concentrations. This study evaluated whether there was any interaction between gabapentin enacarbil (GEn), which is a prodrug of gabapentin, and morphine in terms of pharmacokinetics, pharmacodynamics, safety, and tolerability. ⋯ No significant pharmacokinetic interaction between the 2 drugs was seen in this study. The VAS data suggest that the potential exists for increased adverse effects when GEn and morphine are coadministered. ClinicalTrials.gov identifier: NCT01476124.
