Gabapentin and pregabalin belong to the same class of medicines — gabapetinoids. So, there are a lot of similarities between them. They both work in a similar way, although Pregabalin and gabapentin can both provide relief from pain and be effective ways to manage seizure disorders. However, it’s important to consider the differences between them. Pregabalin is more rapidly absorbed compared to gabapentin, which has a slower absorption rate. Gabapentin is indicated as adjunct therapy for partial seizures and postherpetic neuralgia. 4 Pregabalin is indicated for the same uses as gabapentin, plus the management of fibromyalgia and neuropathic pain associated with diabetes, specifically diabetic neuropathy. 5 Compare Gabapentin vs Pregabalin head-to-head with other drugs for uses, ratings, cost, side effects and interactions. Gabapentin and pregabalin are both used to treat partial-onset seizures and nerve pain from shingles (postherpetic neuralgia). Additionally, gabapentin and pregabalin are used off-label to treat a variety of mental health and pain disorders. Gabapentin (Neurontin <sup>1</sup> ) and pregabalin (Lyrica <sup>2</sup> ) are first- and second-generation α2δ ligands, respectively, and are both approved for use as adjunctive therapy in pain control. Although they do not bind to gamma-aminobutyric acid (GABA) receptors they have been successfull Lyrica and gabapentin are two prescription drugs that treat some seizures and nerve pain. Lyrica CR is an extended-release tablet that doctors do not prescribe for all of the same conditions Lyrica and gabapentin are two prescription drugs used to treat nerve pain and focal onset seizures. Find out how they’re alike and different. If you’re not in the same household, stay on 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. One of the primary distinctions between gabapentin and pregabalin is that the Food and Drug Administration has approved both drugs for some of the same uses but also different ones. In the chart below, we have given the indications for which the FDA approves pregabalin and gabapentin [1]: Pregabalin (Lyrica) and gabapentin (Neurontin) are both approved to treat nerve pain. How are they different, and which one is preferred? Compare both meds here. 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. 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. Using gabapentin together with pregabalin may increase side effects such as dizziness, drowsiness, confusion, and difficulty concentrating. Some people, especially the elderly, may also experience impairment in thinking, judgment, and motor coordination. 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. Gabapentin and Lyrica (pregabalin) are two common drugs prescribed to treat several different medical conditions, including nerve pain. In 2019 alone, more than 47 million gabapentin prescriptions and more than nine million pregabalin prescriptions were filled in the U.S. But for all the similarities between the drugs, you should know some key differences if you take one of these [] Gabapentin is different from pregabalin in terms of pharmacokinetics in a way that with gabapentin, there is a saturation of its absorption while pregabalin has linear kinetics. Although this was not a problem with this patient because she was on a comparatively smaller dose of gabapentin to start on and rather than adding pregabalin, the dose Gabapentin is an anti- seizure (anti-convulsant) drug that is used for preventing seizures and for treating post-herpetic neuralgia, the pain that follows an episode of shingles. Doctors do not know how gabapentin works. Gabapentin structurally resembles the neurotransmitter gamma aminobutyric acid (GABA). Gabapentin is not the same as pregabalin, even though they both belong to the same class of medicine, called gabapentinoids, and work similarly. Lyrica and Lyrica CR are the only brands of pregabalin. Neurontin is a brand name for gabapentin. Other brands of gabapentin include Gralise and Horizant. But why would pregabalin be regulated by the DEA, while gabapentin is not, given that they are in the same class of medications? The answer has to do with the timing of the FDA trials. Gabapentin was approved in the 1990s when the FDA imposed fewer testing requirements.
