Lyrica (pregablin) and gabapentin 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 ). 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. While gabapentin and Lyrica belong to the same medication family and work similarly, they have several important differences that can affect your treatment experience. Chemical Structure and Action Though structurally similar, Lyrica binds more effectively to nerve receptors than gabapentin .[4] There are numerous reasons as to why gabapentin is currently, and has historically, been more popular than pregabalin, including: (1) its release ~11 years prior to that of pregabalin; (2) its status as the only “gabapentinoid” medication available (for ~11 years prior to gabapentin); (3) its ability to treat the same medical conditions as 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 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 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. 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. Lyrica is the brand name for the drug pregabalin, and gabapentin is the name of the medication that is used in drugs such as Neurontin, Gralise, and Horizant. All of these drugs are prescribed as anticonvulsant or antiepileptic medications. 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 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 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. Applies to: gabapentin and Lyrica (pregabalin) 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. 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]: Gabapentin and Lyrica (pregabalin) generally aren't used together due to their numerous similarities. Taking both gabapentin and Lyrica together would generally be considered a 'therapeutic duplication', but there is some evidence of the potential positive benefits of this. Gabapentin and pregabalin are FDA-approved to treat some of the same conditions, including postherpetic neuralgia in adults. Both drugs are also indicated to treat partial seizures in adults and certain children with epilepsy (a seizure disorder) when taken along with other medication. 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. 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 [] 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. However
