The Clinical Difference between Gabapentin and Pregabalin: Data from a Pilot Comparative Trial Bentham Science

The main differences are their indications—specific uses that the Food and Drug Administration (FDA) has approved them to treat—and their dosages. Gralise is indicated for postherpetic neuralgia and taken as an 1800 mg maintenance dose once a day. The AUC of 1800 mg of Gralise is slightly less than 1800 mg of the standard formulation. In addition, the average maximum concentration (Cmax) of Gralise is slightly higher than 1800 mg of the standard form, and minimum concentration (Cmin) is slightly lower.

Your healthcare provider will give you a lower dose when you start treatment with either drug. We aim to evaluate the feasibility of N-of-1 trials to compare pregabalin and gabapentin for individual presentations of neuropathic pain. Pregabalin is a medication used to treat neuropathic pain, seizures, and anxiety disorders. It is also structurally similar to GABA but does not bind with GABA or other benzodiazepine receptors. It binds to the α2δ1 subunit and inhibits excitatory neurotransmitters, reducing abnormal electrical activity in the brain. However, there is no evidence related to the effect of Pregabalin on dopamine, serotonin, and opiate receptors.

Addiction Treatment for Gabapentin and Pregabalin Addiction and substance abuse can happen to anyone. Whether you’ve been prescribed pregabalin or gabapentin or you’ve been taking it recreationally, it is possible to develop a substance dependence. Pregabalin is approved by the European Medicines Agency to treat generalized anxiety disorder (GAD). Nonetheless, pregabalin is used off-label in the US to treat various anxiety disorders such as generalized anxiety disorder, social anxiety disorder, panic disorder, and obsessive-compulsive disorder (OCD).

Lyrica vs Gabapentin Withdrawal Symptoms

The efficacy can be predicted when the dosage is adjusted, and the bioavailability is not related to the dose and is above 90%. Gabapentin has nonlinear pharmacokinetic characteristics, and is only absorbed in the small intestine with a relatively slow absorption rate. The maximum blood concentration is generally reached about 3h after taking the drug, and the absorption is nonlinearly related to the dose. The pharmacokinetics after taking the drug cannot be predicted, and the blood concentration cannot increase with an increase in the drug dose. The absorption of gabapentin is limited by the carrier on the transporter.

what is the difference between gabapentin and pregabalin

Pregabalin is approved for additional uses, including fibromyalgia and nerve pain in certain adults. It is generally prescribed to be taken three times per day for pain relief. Your healthcare provider may adjust the dosage based on your response to the drug. If you are not experiencing sufficient pain relief, your provider may increase the dosage of gabapentin. Lyrica and gabapentin are antiepileptic medications that have a similar mechanism of action.

Side Effects & Safety

However, Lyrica is absorbed more completely and more quickly into the body than gabapentin. The best option will depend on factors like the condition being treated, whether you have tried one treatment option already, and the cost of the drug. There are few studies directly comparing how well Lyrica and gabapentin work. But studies show that both Lyrica and gabapentin are effective for treating partial onset seizures and nerve pain that occurs after shingles. Both Lyrica and gabapentin treat partial onset seizures and nerve pain that occurs after shingles.

Both gabapentin and pregabalin have the potential to result in physical and psychological dependence. This risk increases significantly if these drugs are used in high doses or over long periods of time. The brand name drug Horizant, containing gabapentin enacarbil, is approved to treat moderate to severe restless legs syndrome and also postherpetic neuralgia. It’s typically prescribed in combination with other seizure medications.

  • You should not take more Lyrica or gabapentin than prescribed, even if your symptoms aren’t going away with treatment.
  • Based on the current classification by the DEA, pregabalin is considered to have a higher risk for abuse and for the development of physical dependence than products containing gabapentin.
  • Aside from treating seizures caused by epilepsy, these two can also be useful in treating other health conditions.

Outcomes were assessed at baseline, then at weeks 4, 8, 10, 14, and 18. Baseline and weeks 8, 10, and 18 were considered the primary times for the primary outcome that represented the start and finish of each medication. Because PGB and GBP are predominantly renally excreted, patients with an estimated creatinine clearance of less than 60 mL per minute were also excluded. how to get generic lyrica without insurance Pregabalin and gabapentin are both primarily used to treat nerve pain, seizures disorders, and related conditions, although they may also be used for off-label indications. This includes any surgeries, allergic reactions, and any medical conditions you have or have had, as this information helps healthcare providers determine which medications are safe for your situation.

The other option included a gradual transition from gabapentin to pregabalin. The authors found that those who responded well to gabapentin and those who did not showed additional benefit with decreased pain when they were switched to pregabalin. Patients taking pregabalin also had improved pain control compared with those who remained on gabapentin. Unlike the original formulation, absorption of gabapentin enacarbil is not saturated at high doses, as MCT-1 is expressed in high levels in the intestinal tract. The drug undergoes near-complete first pass hydrolysis to gabapentin by non-specific carboxylesterases mainly in enterocytes, as well as in the liver to a lessor degree. Careful selection and monitoring of the medication options can minimize risks to the injured worker and achieve effective pain relief.

Furthermore, Gabapentin is known to promote the plasma concentration of serotonin. Because pregabalin and gabapentin have the same makeup, it will follow that the side effects that patients may incur from taking one of these medications may be similar, though there can be differences as well. Unlike gabapentin, pregabalin can cause less side effects that are specifically dependent on the dosage. Lyrica and gabapentin are prescription drugs used to treat nerve pain and partial-onset seizures. Lyrica is a brand-name drug containing pregabalin while gabapentin is a generic drug known by the brand names Neurontin, Gralise, and Horizant.
