  • It is also used for the treatment of symptoms of generalized anxiety disorder (GAD).
  • The Exact Mechanism OF Action is unknown However It’s thought to work by binding to calcium channels found on nerve cells in the brain and spinal cord. This reduces the release of various neurotransmitters Like Glutamate and Nor epinephrine from these nerve cells.These two chemical substances are responsible for transmitting Pain signals in the brain and spinal cord. As Pregabalin Reduces the release of these substances that’s the reason they are used in the treatment of Nerve Pain.It inhibit the voltage gated N type of calcium channels and prevent the entry of calcium into the presynaptic neurons.This will prevent the depolarization of these neurons.
