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. Several studies reviewing conversion of gabapentin to pregabalin predict that a rough ratio for conversion is about 6:1 gabapentin to pregabalin. In addition, a direct switch from gabapentin to pregabalin seems to be well tolerated, making the conversion simple. 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 Switching between gabapentin and pregabalin for neuropathic pain. If treatment is not effective or tolerated, NICE guidance for neuropathic pain in adults recommends switching to an alternative treatment (1) may include switching between the gabapentinoids: gabapentin and pregabalin (1) Pregabalin versus gabapentin: Pregabalin, like gabapentin, is an amino acid derivative of gamma-amino butyric acid (GABA analogue). 1,2 Pregabalin is the pharmacologically active S-enantiomer of 3-aminomethyl-5-methyl-hexanoic acid, and has a similar pharmacological profile to gabapentin. 1 These agents are part of a unique class that have a 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. There is cross tolerance between Lyrica and Gabapentin. Meaning that if you go on a high dose of lyrica you should be able to tolerate a high dose of Gabapentin. Conversion between Lyrica and gabapentin is generally well tolerated and direct switching minimizes potential for gaps in pain relief. In the absence of seizure history, the drugs can be directly interchanged; patients can be advised to discontinue Lyrica and begin gabapentin the following day. 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. Previously, studies have shown 6:1 conversion factor, from gabapentin to pregabalin. (Pain Med. 2011 Jul;12(7):1112-6.) The Literature: Am J Ther. 2013 Jan;20(1):32-6.* Compared unidirectional switch from gabapentin to pregabalin with two rotation strategies: 1. Direct switch o Stop gabapentin, initiate pregabalin at next scheduled dose period Lyrica 150 mg is approximately 2–3 times more potent than gabapentin. This means that lower doses of Lyrica achieve the same therapeutic effects as higher doses of gabapentin, which is why the conversion ratio leans towards 600–900 mg gabapentin for every 150 mg of Lyrica. In the scenario above (gabapentin 300 TID and pregabalin 150 mg BID), if the patient’s pain was not under control, as an initial step, I would probably go up on the gabapentin by 600-900 mg (total daily dose) and reduce the pregabalin by 100-150 mg (total daily dose). 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. Both transition designs were studied at 3 dosage levels: gabapentin 900 mg/d to pregabalin 150 mg/d, gabapentin 1800 mg/d to pregabalin 300 mg/d, and gabapentin 3600 mg/d to pregabalin 600 mg/d. Overall drug exposure achieved during the 2 transition designs was the sum of the gabapentin and pregabalin concentrations, expressed as pregabalin gabapentin to pregabalin.3 There is no established guidance on converting between gabapentin and pregabalin.4 The manufacturers of both pregabalin and gabapentin advise that if they are to be stopped or changed to another medication, the dose should be tapered gradually over at least one week.4 This gradual withdrawal is to minimise Lyrica (pregablin) and gabapentin are anti-epileptic medications used to treat seizures and nerve pain (neuropathic pain).
