Pregabalin vs Gabapentin: Which Nerve Pain Medication Works Best?

If you are experiencing nerve pain, you are not alone. It’s estimated that around 7-10% of the general population worldwide suffers from chronic neuropathic pain. This type of pain can be challenging to treat and may not respond well to traditional pain medications. Pregabalin and Gabapentin are two commonly prescribed medications for nerve pain, but which one works best? In this article, we will compare Pregabalin 300mg to Gabapentin and help you determine which medication may be right for you.

What is Pregabalin?

Pregabalin is an anticonvulsant medication that is used to treat neuropathic pain, anxiety disorders, and epilepsy. It works by binding to the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system, which reduces the release of neurotransmitters that are involved in pain signaling. Pregabalin is sold under the brand name Lyrica and is available in capsule and liquid form.

How does Pregabalin work?

Pregabalin works by reducing the release of neurotransmitters that are involved in pain signaling. By binding to the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system, Pregabalin reduces the influx of calcium ions into nerve cells, which decreases the release of neurotransmitters such as glutamate, substance P, and noradrenaline. This results in a reduction in pain signals sent to the brain.

What are the side effects of Pregabalin?

The most common side effects of Pregabalin include dizziness, drowsiness, dry mouth, blurred vision, weight gain, and swelling in the hands and feet. Less common side effects include headaches, nausea, and constipation. Some patients may experience more severe side effects such as allergic reactions, difficulty breathing, and suicidal thoughts.

What is Gabapentin?

Gabapentin is also an anticonvulsant medication that is used to treat neuropathic pain, seizures, and restless leg syndrome. It works by binding to the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system, which reduces the release of neurotransmitters that are involved in pain signaling. Gabapentin is sold under the brand name Neurontin and is available in capsule and liquid form.

How does Gabapentin work?

Gabapentin works by binding to the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system, which reduces the influx of calcium ions into nerve cells. This decreases the release of neurotransmitters such as glutamate, substance P, and noradrenaline, resulting in a reduction in pain signals sent to the brain.

What are the side effects of Gabapentin?

The most common side effects of Gabapentin include dizziness, drowsiness, and fatigue. Less common side effects include headaches, nausea, and diarrhea. Some patients may experience more severe side effects such as allergic reactions, difficulty breathing, and suicidal thoughts.

Pregabalin vs Gabapentin

While both Pregabalin vs Gabapentin is anticonvulsant medications that work by binding to the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system, there are some differences between the two medications that may make one more suitable than the other.

Effectiveness

Several studies have compared the effectiveness of Pregabalin and Gabapentin in the treatment of neuropathic pain. A meta-analysis of these studies found that Pregabalin was more effective than Gabapentin at reducing pain intensity and improving sleep quality in patients.

Dosage

Pregabalin is available in capsule and liquid form, with the most common dosage being 300mg per day, divided into two or three doses. Gabapentin is available in capsule and liquid form, with the usual dose starting at 300mg per day and gradually increasing to a maximum of 3600mg per day.

Side Effects

Both Pregabalin and Gabapentin can cause dizziness, drowsiness, and fatigue, which may affect a patient’s ability to drive or operate machinery. Pregabalin is more likely to cause weight gain and peripheral edema (swelling in the hands and feet) compared to Gabapentin. On the other hand, Gabapentin is more likely to cause gastrointestinal side effects such as nausea and diarrhea.

Cost

The cost of Pregabalin and Gabapentin varies depending on the country, pharmacy, and insurance coverage. In general, Pregabalin is more expensive than Gabapentin. However, Pregabalin is available as a generic medication, which may be cheaper than the brand name Lyrica.
