Randomized Controlled Trial Multicenter StudyEfficacy and tolerability of lisdexamfetamine dimesylate (NRP-104) in children with attention-deficit/hyperactivity disorder: a phase III, multicenter, randomized, double-blind, forced-dose, parallel-group study.
Lisdexamfetamme dimesylate (LDX) is a therapeutically inactive amphetamine prodrug. It was developed with the goal of providing an extended duration of effect that is consistent throughout the day, with a reduced potential for abuse, overdose toxicity, and drug tampering. Following ingestion, the pharmacologically active d-amphetamine molecule is gradually released by rate-limited hydrolysis. ⋯ In this population of children with ADHD, treatment once daily with the prodrug LDX at doses of 30 to 70 mg appeared to be effective and had a tolerability profile similar to those of currently marketed extended-release stimulants.

Randomized Controlled Trial Multicenter Study Comparative StudyEffects of parecoxib and dipyrone on platelet aggregation in patients undergoing meniscectomy: a double-blind, randomized, parallel-group study.
Based on a PubMed search of the literature using the terms parecoxib, platelets, thromboxane, bleeding, and platelet aggregation, the effects of parecoxib on platelet function have not fully been established under clinical conditions. ⋯ Platelet aggregation and TxB(2) formation were significantly lower for 6 hours in dipyronetreated patients compared with parecoxib-treated patients. In contrast, TxB(2) formation was increased with parecoxib 6 hours after administration compared with pretreatment values. In this small study, parecoxib did not affect platelet aggregation in a population of patients undergoing routine partial meniscectomy (or a similar arthroscopic procedure) under clinical conditions.
