Given the 6-h half-life of both gabapentin and pregabalin [11, 50], this will permit sufficient wash-out and elimination of carry-over effects between treatment periods. Compare Gabapentin vs Pregabalin head-to-head with other drugs for uses, ratings, cost, side effects and interactions. Keywords: Gabapentin, pregabalin, pain management, adverse effects, pharmacology Introduction The gabapentinoid drugs gabapentin and pregabalin are antiepileptic drugs that are considered as first-line treatments for the management of neuropathic pain. 1 Pregabalin is also approved for generalised anxiety disorders in the United Kingdom. Compare Gabapentin vs Lyrica head-to-head with other drugs for uses, ratings, cost, side effects and interactions. The half-life of gabapentin immediate-release formulation is 5–7 hours in patients with normal renal function and is prolonged up to 52 hours in patients with CrCl<30 mL/min. 26 The half-life of pregabalin is 16.7 hours in patients with CrCl 30–59 mL/min, 25 hours in patients with CrCl 15–29 mL/min, and 48.7 hours in patients with CrCl<15 Pregabalin and gabapentin are members of a unique class of compounds characterized by high affinity binding to the alpha-2-delta (α2δ) protein in the CNS. Both have been shown to be effective as adjunctive therapy for partial seizures and neuropathic pain disorders. Clinical pharmacology studies conducted to characterize the pharmacokinetics, bioavailability, and drug-drug interaction The chart below compares the half-life of gabapentin and pregabalin. It takes about five half-lives (the time it takes for the amount of a drug's active substance in your body to reduce by half) to clear a drug from your system. Gabapentin and pregabalin are medications used to treat similar conditions, but they differ in their chemical structures and modes of action. Gabapentin is a generic drug that targets certain types of nerve pain, while pregabalin is a more potent and specific medication that is also used to treat nerve pain as well as epilepsy and generalized anxiety disorder. The dose of pregabalin ranged from 150 to 600 mg/day (divided three times a day). Subjects were permitted to remain on pain relieving medications including gabapentin. Patients were evaluated quarterly after a pregabalin holiday (mean duration 7 days) to evaluate pain using a 5-point scale (0=not at all, 4=very much worse). Comparison of gabapentinoids gabapentin (Neurontin) and pregabalin (Lyrica), differences between gabapentin and pregabalin chart, latest comparative clinical trials, up-to-date drug information. Compare Gabapentin vs Gabapentin Enacarbil head-to-head with other drugs for uses, ratings, cost, side effects and interactions. Both drugs are excreted renally, with elimination half-lives of approximately 6 hours. Pregabalin and gabapentin both show dose-response relationships in the treatment of postherpetic neuralgia and partial seizures. For neuropathic pain, a pregabalin dosage of 450 mg/day appears to reduce pain comparably to the predicted maximum effect of Additionally, Lyrica has a more predictable absorption rate and a longer half-life, allowing for less frequent dosing compared to Gabapentin. However, Gabapentin is available in generic form, making it a more cost-effective option for some patients. Lyrica may also be used to treat neuropathic (nerve) pain associated with diabetic peripheral neuropathy or postherpetic neuralgia, spinal cord injury, and fibromyalgia Gabapentin may also be used to treat nerve pain caused by shingles (herpes zoster) and gabapentin enacarbil, brand name Horizant, is also approved for restless legs syndrome (RLS). Lyrica (pregabalin) is intended to be the successor to Neurontin (gabapentin) and was first approved by the U.S. FDA in 2004 for the treatment of epilepsy; diabetic neuropathic pain; and postherpetic neuralgia. Lyrica (Pregabalin) vs. Neurontin (Gabapentin) Equally important, pregabalin can be more rapidly titrated to an effective dose range than gabapentin (1-2 days for pregabalin versus approximately 9 days for gabapentin) (3). Other differences Research suggests a target dose of at least 900-3600mg/day (in divided doses) of gabapentin to maintain analgesia for persistent pain (4,5). Lyrica (pregabalin) will stay in your blood (plasma) for about 35 hours, but its clinical effect may wear off before this time. Studies have shown pregabalin to be detectable in urine for up to 5 to 6 days. Pregabalin, the active ingredient in Lyrica, has a half-life of 6.3 hours. The half-life of a drug is the time it takes for the plasma (blood) concentration of a drug to reduce by one-half The time pregabalin and gabapentin stay in the body depends on their half-life, which is the time it takes for half of the drug to be eliminated. Pregabalin has a half-life of about six hours, meaning it is mostly cleared within one and a half days after the last dose.
