BACKGROUND Pregabalin is widely used perioperatively. The authors explored the effects of pregabalin, remifentanil, and their combination on experimental pain, ventilatory, and cognitive function. METHODS In a randomized, double-blinded crossover study, 12 volunteers received (1) pregabalin + placebo, (2) placebo + remifentanil, (3) pregabalin + remifentanil, and (4) placebo + placebo. Pregab...

BACKGROUND Pregabalin, (S)-3-aminomethyl-5-methyl hexanoic acid, is a ligand for the α2δ subunit (a component of voltage-gated calcium channels) and has analgesic and anticonvulsant properties. Glutamate uptake by glutamate transporters may be a mechanism for these properties. We investigated the effects of pregabalin on the activity of the neuronal glutamate transporter type 3 (EAAT3). METHO...

AIMS The aim of our study was to compare the efficacy, safety, and quality of life of combination therapy with controlled-release (CR) oxycodone plus pregabalin versus monotherapy with either CR oxycodone or pregabalin in patients with neuropathic pain. MATERIALS AND METHODS Patients with moderate to severe neuropathic pain, despite the use of various pharmacologic treatments prior to study e...

BACKGROUND In this study we aimed to explore the effects of pregabalin on a traumatic brain injury model in rats. MATERIAL AND METHODS This study included 40 adult male Sprague-Dawley rats randomized into 4 groups, each of which contained equal numbers of animals. The control group had no head trauma and thus was not treated. The trauma group had head trauma but was not treated. The pregabali...

This was a multicenter, double-blind (DB), placebo-controlled, randomized discontinuation trial to evaluate the efficacy of pregabalin monotherapy for durability of effect on fibromyalgia (FM) pain. The trial included a 6-week open-label (OL) pregabalin-treatment period followed by 26-week DB treatment with placebo or pregabalin. Adults with FM and 40-mm score on 100-mm pain visual analog scale...

Pregabalin, primarily used to manage neuropathic pain and fibromyalgia, is categorized as a Schedule V drug (ie, lowest potential for abuse) in the US Drug Enforcement Administration's Controlled Substances Act. Because pregabalin is not recognized as a drug with high-abuse potential, data on pregabalin abuse and addiction are lacking. The authors report a case of a 35-year-old woman with a his...

OBJECTIVE To evaluate the safety, tolerability, and efficacy of adding milnacipran to pregabalin in patients with fibromyalgia who have experienced an incomplete response to pregabalin. METHODS In this randomized, multicenter, open-label study, patients received pregabalin 300 or 450 mg/day during a 4- to 12-week run-in period. Patients with weekly recall visual analog scale (VAS) pain score ...

OBJECTIVE Current drug therapies for generalized anxiety disorder have limitations. In a controlled trial, the novel agent pregabalin was studied for the treatment of patients with generalized anxiety disorder. METHOD In this double-blind study, patients with DSM-IV generalized anxiety disorder were randomly assigned to receive pregabalin (150 mg/day or 600 mg/day), lorazepam (6 mg/day), or p...

BACKGROUND Gabapentin and pregabalin have wide-ranging therapeutic actions, and are structurally related to the inhibitory neurotransmitter GABA. Gabapentin, pregablin and GABA can all modulate voltage-activated Ca2+ channels. In this study we have used whole cell patch clamp recording and fura-2 Ca2+ imaging to characterise the actions of pregabalin on the electrophysiological properties of cu...

BACKGROUND Gabapentin and pregabalin are antiepileptic drugs that are also used for chronic pain treatment. This study evaluated the effects of pregabalin and gabapentin on postoperative pain in patients undergoing laparoscopic cholecystectomy. METHODS A total of 108 candidates for elective laparoscopic cholecystectomy were randomly assigned to gabapentin (n = 36), pregabalin (n = 36), and pl...
