The 2 auxiliary subunits ( 2 -1 and 2 -2) of voltage-sensitive calcium channels are thought to be the site of action of pregabalin (Lyrica), a drug that has been shown to be anxiolytic in clinical trials for generalized anxiety disorder. Pregabalin and the chemically related drug gabapentin have similar binding and pharmacology profiles, demonstrating high-affinity, in vitro binding to both 2 -...

Pregabalin is a new synthetic molecule and a structural derivative of the inhibitory neurotransmitter gamma-aminobutyric acid. It is an alpha2-delta (alpha2-delta) ligand that has analgesic, anticonvulsant, anxiolytic, and sleep-modulating activities. Pregabalin binds potently to the alpha2-delta subunit of calcium channels, resulting in a reduction in the release of several neurotransmitters, ...

The development of combination therapy is a coherent approach in severe pain treatment. The present study investigated the antinociceptive effect of pregabalin alone and in combination with tramadol in acute pain modeling. Therefore, three groups of male mice received either pregabalin (1 to 400 mg/Kg), tramadol (10 to 80 mg/Kg) or their combination intraperitoneally. Then latency time, maximum...

Introduction. Pain after cardiac surgery affects long-term patient wellness. This study investigated the effect of preoperative pregabalin on acute and chronic pain after elective cardiac surgery with median sternotomy. Methods. Prospective double blind study. 93 cardiac surgery patients were randomly assigned into three groups: Group 1 received placebo, Group 2 received oral pregabalin 75 mg, ...

PURPOSE Gabapentin and pregabalin are antiepileptic drugs (AEDs) with epilepsy and neuropathic pain indications. The purpose of this study was to investigate pharmacokinetic variability of gabapentin and pregabalin and indications for therapeutic drug monitoring (TDM) in clinical practice with focus on gender aspects. METHOD Anonymous data from routine TDM-service at the National Center for E...

PURPOSE Studies of pregabalin for the treatment of central neuropathic pain have been limited to double-blind trials of 4-17 weeks in duration. The purpose of this study was to assess the long-term safety and tolerability of pregabalin in Japanese patients with central neuropathic pain. The efficacy of pregabalin was also assessed as a secondary measure. PATIENTS AND METHODS This was a 53-wee...

BACKGROUND Pregabalin is a potent ligand for alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system, which exhibits potent anticonvulsant, analgesic and anxiolytic activity. The pharmacological activity of pregabalin is similar to that of gabapentin and shows possible advantages. Although it shows analgesic efficacy against neuropathic pain, very limited evidence ...

Previous published work with the novel anticonvulsant, analgesic and anti-anxiety medication, pregabalin (Lyrica), has shown that it has anxiolytic-like actions in several animal behavioral models. However, pregabalin is structurally and pharmacologically different from other classes of known anxiolytic drugs, and the mechanisms that alter brain activity to produce anxiolytic-like actions are n...

BACKGROUND Pregabalin is a novel compound that has been shown to have efficacy in the treatment of generalised anxiety disorder and is licensed for the treatment of the disorder in the European Union. AIMS The current study was designed to evaluate the safety and efficacy of pregabalin, an alpha(2)delta-ligand, in the treatment of generalised anxiety disorder in people 65 years and older. M...

Two cases of pregabalin neurotoxicity in chronic kidney disease patients Sir We report two cases of newly presenting pregabalin neuro-toxicity in chronic kidney disease (CKD) patients. A 67-year-old man was referred to our nephrology department for consultation. He had been admitted to the department of orthopedics because of spinal stenosis and had undergone surgery 5 weeks earlier. He had sta...
