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. Différences entre le Lyrica et le Gabapentin. Bien que le Lyrica et le Gabapentin soient tous deux utilisés pour traiter les douleurs neuropathiques, il existe certaines différences entre ces deux médicaments. Structure chimique. La principale différence entre le Lyrica et le Gabapentin réside dans leur structure chimique. As gabapentinoids, Lyrica (pregabalin) and Neurontin (gabapentin) are chemical analogues of the inhibitory neurotransmitter GABA (gamma-aminobutyric acid) that interact with α2δ subunit-containing voltage-dependent calcium channels. Gabapentin and pregabalin are both similar in structure and mechanism of action. They are both structurally similar to gamma aminobutyric acid (GABA), an inhibitory neurotransmitter. They are both structurally similar to GABA – though they have no GABAergic activity – and share functional similarities to the amino acid leucine. Pharmacokinetics: Gabapentin has a slow oral absorption following oral administration, reaching peak plasma concentrations after about 3-4 hours. Pregabalin vs Gabapentin: Overview. Pregabalin and gabapentin are prescription drugs that are used to treat similar conditions. But these two drugs are not the same. Please continue reading to learn about the differences between pregabalin vs gabapentin . Definition and Classification What Drugs Interact With Lyrica vs. Gabapentin? Lyrica Drug Interactions. The sedative effects of Lyrica may increase along with alcohol and other drug interactions that cause sedation. The risks of weight gain, fluid retention, and heart failure can be caused by Lyrica interactions with Pioglitazone (Actos) and rosiglitazone (Avandia). 2025 Copyright | All Rights Reserved.

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. Although both gabapentinoids are absorbed in the small intestine, pregabalin is also absorbed in the proximal colon. Absorption of gabapentin is solely dependent on LAT that are easily saturable, resulting in dose-dependent pharmacokinetics. 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. 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 there are many similarities between Lyrica vs. gabapentin, there are also many differences you should know about. Key differences between Lyrica vs. gabapentin include: The DEA has classified Lyrica as a Schedule V controlled substance. Similar drugs in this class, like gabapentin, have not been so classified in all states. Gabapentin contains the active ingredient gabapentin. Both Lyrica and gabapentin belong to a class of drugs known as anticonvulsants. The Food and Drug Administration (FDA) has approved 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.
