The particular NNTs for pregabalin and gabapentin were 7.71 and 7.16, respectively. 10 A more recent meta-analysis in 2022 specifically focused on post-herpetic neuralgia and found greater efficacy with pregabalin in alleviating pain and improving global perception of pain and sleep. 15 Another meta-analysis published in 2021 reported similar Pooled risk ratio (RR) of pregabalin (PGB) vs. gabapentin (GBP) for adverse events (AEs). There was no significant difference between two drugs for AEs. CI: confidence interval, df: degree of freedom. PGB vs. placebo: Drowsiness, dizziness, edema, and peripheral edema were the most common AEs in the selected studies [41,43,44]. In this context, numerous drugs have been developed for the management of neuropathic pain, including duloxetine, amitriptyline, gabapentin, and pregabalin, among others. Gabapentin and pregabalin are analogs of gamma-aminobutyric acid (GABA) and share a similar mechanism of action, although they differ in some aspects. Gabapentin and Lyrica are similar medications used to treat nerve pain and epilepsy, but Lyrica has broader FDA approval and typically requires lower, less frequent doses. Studies show Lyrica tends to work faster and more predictably for nerve pain, especially for FDA-approved conditions like fibromyalgia and diabetic neuropathy. We would like to show you a description here but the site won’t allow us. When you're comparing gabapentin versus Lyrica, you should consider the benefits and risks. Gabapentin is used to treat partial seizures that occur with epilepsy and nerve pain resulting from nerve Pregabalin (Lyrica) and gabapentin (Neurontin and others) are drugs used to prevent seizures and to treat nerve pain associated with various conditions (shingles, diabetic neuropathy). Lyrica and gabapentin both cause similar side effects, including tremors, blurred or double vision, memory or concentration problems, dizziness, and drowsiness. Both Lyrica and gabapentin are used as anti-epileptic medications and to treat nerve pain. But there are several differences between them. The main differences between Lyrica and gabapentin are: Lyrica is a brand name for pregabalin. Gabapentin is a generic name - brands of gabapentin include Neurontin, Gralise, and Horizant. In this context, the objective of this meta-analysis is to evaluate and compare pregabalin vs. gabapentin in terms of efficacy and safety in the treatment of neuropathic pain, aiming to provide a solid foundation for clinical decision-making and improve the management of this condition in medical practice. 2. Methods 2.1. Eligibility criteria Lyrica and gabapentin are two prescription drugs used to treat nerve pain and focal onset seizures. Find out how they’re alike and different. Gabapentin is also used for treating neuropathic pain. The bioavailability of this drug is less than 90% (less than that of Lyrica). They come in tablet and capsules with strengths of 100 mg, 300 mg, 400 mg, 600 mg, and 800 mg. The drug also has an oral solution available at 250 mg/5 ml. Based on studies of gabapentin and pregabalin in epilepsy, the EC50 values of pregabalin and gabapentin were estimated to be about 9.77 mg/mL and 23.9 mg/mL, respectively. 9 From these data, pregabalin was estimated to be about 2.4 times more potent. For neuropathic pain, pregabalin’s potency ratio may be even greater. Efficacy: Pregabalin vs. Gabapentin . Numerous clinical trials have examined whether pregabalin or gabapentin is more effective for treating specific conditions. Some of the trial findings are explained below. Lyrica (pregabalin) is both chemically and structurally similar to gabapentin. It does however, have a unique way of being absorbed and has much better bioavailability than gabapentin does. Lyrica is almost totally absorbed (~90%) very quickly after taking by mouth. It's maximum absorption rate is nearly three times gabapentin. Lyrica and gabapentin are two prescription drugs that treat some seizures and nerve pain. Here's a comparison of how the drugs are similar and different. Research supports the use of the anticonvulsants gabapentin (Gralise, Neurontin, Horizant) and pregabalin (Lyrica) to help relieve pain caused by damaged nerves. Both gabapentin and pregabalin are particularly effective in the treatment of postherpetic neuralgia, diabetic neuropathy and pain caused by a spinal cord injury. Gabapentin is an anticonvulsant with pain-relieving effects that may be used to treat certain seizure disorders or relieve nerve pain. Common side effects include dizziness or drowsiness and it may more. Lyrica can help relieve nerve pain and control seizures but it is likely to cause drowsiness. Pregabalin (Lyrica) and gabapentin (Neurontin) are medications that treat certain types of seizures and nerve pain. Pregabalin has more FDA approved uses. Both are frequently used off-label for a wide range of health conditions. When comparing pregabalin versus gabapentin, they work in similar ways but pregabalin is absorbed more quickly and fully. First, gabapentin is primarily absorbed in the small intestine, while pregabalin is absorbed at multiple sites, the small intestine and the ascending portion of the colon. 6 Second, gabapentin’s absorption is saturable; meaning that as gabapentin doses increase, the rate of absorption and resulting bioavailability decreases. For this study, a key measure was whether a medication reduced discomfort by 50%. The most effective treatment was nortriptyline. Of the study subjects taking this medication, 25% reported their discomfort improved by at least 50%. The least effective treatment was pregabalin: only 15% of study subjects reported that much improvement.
