While gabapentin (Neurontin) and pregabalin (Lyrica) share many similarities, there are a few things that set them apart. We’ll highlight seven key differences between these medications below. 1. Pregabalin is FDA approved for more uses than gabapentin, but both are often used off-label. Gabapentin and pregabalin are similar drugs but differ in several distinct ways. The main differences are their indications—specific uses that the Food and Drug Administration (FDA) has approved them to treat—and their dosages. Both pregabalin and gabapentin are antiepileptic medications that bare structural resemblance to gamma-aminobutyric acid (GABA), though neither agent has activity in GABA’s neuronal systems. Gabapentin (often sold under the brand name Neurontin) and pregabalin (brand name Lyrica) are two commonly prescribed medications that work in similar ways. While both belong to a class of drugs called gabapentinoids and are used to treat nerve-related conditions, they have distinct differences that can affect which one might be right for you. Lyrica and gabapentin generally aren't used together due to the similarity in how they work.Nevertheless, preliminary studies evaluating the combined use of low doses of both drugs have found that there may be improved tolerability and pain-relieving effects when compared to the use of a single agent alone. Lyrica (pregablin) and gabapentin (Neurontin) are anti-epileptic medications used to treat seizures and nerve pain (neuropathic pain). Gabapentin is also used to treat nerve pain caused by shingles (herpes zoster). Gabapentin and Lyrica are similar drugs, but they do have some differences. For example, both drugs come as a capsule or liquid solution that you swallow. But gabapentin also comes as a tablet Lyrica is almost totally absorbed (~90%) very quickly after taking by mouth. It's maximum absorption rate is nearly three times gabapentin. This is why the dosage levels of Lyrica are so much lower than the dosage levels of gabapentin. Gabapentin You can see from the chemical structures how closely gabapentin and Lyrica are related. Pregabalin and gabapentin are structurally related to the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). Gabapentin, pregabalin, and GABA all modulate voltage-gated calcium channels. The mechanism of action of gabapentinoids like gabapentin and pregabalin in seizure treatment and pain management is not fully understood. Gabapentin is contraindicated in individuals who have hypersensitivity to this medication or its components, which can cause fever and other symptoms that could become severe. Pregabalin vs Gabapentin â What is the Difference? Pregabalin and gabapentin can both provide relief from pain and be effective ways to manage seizure disorders. Gabapentin (Neurontin) and pregabalin (Lyrica) both belong to a class of drugs called gabapentinoids, which means they work in similar ways. They're both used to treat chronic pain in certain 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. Gabapentin is not the same as pregabalin, even though they both belong to the same class of medicine, called gabapentinoids, and work similarly Use of gabapentin for central neuropathic pain is therefore off-label. However, gabapentin is recommended by NICE as a first-line treatment option for adults with all types of neuropathic pain (except trigeminal neuralgia). Interactions. There are no clinically relevant pharmacokinetic interactions between gabapentin and pregabalin. Though they belong to the same class of medications, gabapentin and Lyrica have several key differences: Lyrica is considered more potent than gabapentin, meaning that lower doses can provide the same effects. It is absorbed more consistently, so doctors can predict its effects more accurately. This is not the case however. Gabapentin is the generic of a different medication, Neurontin. Nevertheless, the chemical structures of Lyrica and gabapentin are nearly identical to one another. The main difference between the two medications is that Lyrica is more potent, and lasts longer per dose than gabapentin. The FDA warns that pregabalin may still lead to some degree of physical or psychological dependence. Potential for Gabapentin and Pregabalin Lawsuits. The new warnings may lead people to file drug lawsuits over breathing-related injuries blamed on gabapentin’s and pregabalin’s respiratory risks. Lyrica (pregabalin) and gabapentin are both prescribed for partial onset seizures and nerve pain that occurs after shingles. Doctors also prescribe Lyrica for other uses. Lyrica is a Neuropathic pain is a prevalent and burdensome condition, and both pregabalin and gabapentin are widely used for its treatment. However, there is a lack of clarity regarding their comparative efficacy and safety. This meta-analysis aims to evaluate and compare the effectiveness and safety of pregabalin vs. gabapentin in managing neuropathic pain. Gabapentin and Lyrica are similar in their chemical composition and in the conditions they are approved to treat. However, some research studies suggest that Lyrica has some advantages, particularly with the control of certain types of pain. Differences in the scheduling of pregabalin and gabapentin is related to: (1) euphoria occurring as an adverse reaction in pregabalin clinical trials (not gabapentin trials); and (2) pregabalin exerting a ~6-fold stronger effect (on voltage-dependent calcium channels) relative to gabapentin; and (3) pregabalin maintaining its high
