Mechanism of Action

Lyrica 150 mg works by binding to a specific subunit of voltage-gated calcium channels in the central nervous system. This binding reduces the release of several neurotransmitters, including glutamate, norepinephrine, and substance P, which are involved in transmitting pain signals. By modulating these neurotransmitters, Lyrica helps to decrease the intensity of pain signals reaching the brain.

Pain Relief

Lyrica action on the nervous system results in effective pain relief for individuals suffering from PHN. Clinical studies have shown that Lyrica significantly reduces pain intensity and improves the overall quality of life for patients with PHN. It helps to alleviate the burning, stabbing, and shooting pains that are characteristic of shingles nerve pain.
