Overview
Pregabalin is an anticonvulsant and analgesic medication used to treat neuropathic pain, fibromyalgia, and as an adjunctive therapy for partial seizures.

Mechanism of Action
It binds to the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system, reducing the release of several excitatory neurotransmitters.

Dosage and Administration
The dosage varies by indication but typically starts at 75 mg or 150 mg per day, given in divided doses, and can be titrated up based on response.

Side Effects
Common side effects include dizziness, somnolence, peripheral edema, and weight gain.

Contraindications
Contraindicated in patients with known hypersensitivity to pregabalin. Caution is advised in patients with heart failure or renal impairment.
