Pregabalin

Pregabalin belongs to a class of drugs called the anticonvulsants. Pregabalin binds with high affinity to the alpha2-delta site (an auxiliary subunit of voltage-gated calcium channels) in central nervous system tissues. Binding to the alpha2-delta subunit may be involved in pregabalin's anti-nociceptive and antiseizure effects.

 

Pregabalin is indicated for:

  • Neuropathic pain associated with diabetic peripheral neuropathy (DPN) 
  • Postherpetic neuralgia (PHN)
  • Adjunctive therapy for the treatment of partial onset seizures in patients 4 years of age and older
  • Fibromyalgia 
  • Neuropathic pain associated with spinal cord injury

 

  • Neuropathic Pain Associated with Diabetic Peripheral Neuropathy: In patients with creatinine clearance of at least 60 mL/min, the maximum recommended dose of LYRICA is 100 mg three times per day (300 mg/day). Begin with 50 mg three times day (150 mg total). Based on efficacy and tolerability, the dose may be increased to 300 mg/day within one week.
  • Postherpetic Neuralgia: In patients with creatinine clearance of at least 60 mL/min, the recommended dose of LYRICA is 75 to 150 mg twice daily, or 50 to 100 mg three times daily (150 to 300 mg/day). Begin with 75 mg twice day, or 50 mg three times day (150 mg/day). Based on efficacy and tolerability, the dose may be increased to  300 mg/day within week.
  • Management of Fibromyalgia: The recommended dose of LYRICA for fibromyalgia is 300 to 450 mg/day. Begin dosing at 75 mg two times a day (150 mg/day). The dose may be increased to 150 mg two times a day (300 mg/day) within 1 week based on efficacy and tolerability. Patients who do not experience sufficient benefit with 300 mg/day may be further increased to 225 mg two times a day (450 mg/day).
  • Neuropathic Pain Associated with Spinal Cord Injury: The recommended dose range of LYRICA for the treatment of neuropathic pain associated with spinal cord injury is 150 to 600 mg/day. The recommended starting dose is 75 mg two times a day (150 mg/day). The dose may be increased to 150 mg two times a day (300 mg/day) within 1 week based on efficacy and tolerability. 
  • Dosing for Adult Patients with Renal Impairment: In view of dose-dependent adverse reactions and since LYRICA is eliminated primarily by renal excretion, adjust the dose in adult patients with reduced renal function.

 

 

  • Angioedema(e.g., swelling of the throat, head and neck) can occur, and may be associated with life-threatening respiratory compromise requiring emergency treatment. Discontinue LYRICA immediately in these cases. 
  • Hypersensitivity reactions(e.g., hives, dyspnea, and wheezing) can occur. Discontinue LYRICA immediately in these patients.
  • Increased seizure frequency or other adverse reactions may occur if LYRICA is rapidly discontinued. Withdraw LYRICA gradually over a minimum of 1 week.
  • Antiepileptic drugs, including LYRICA, increase the risk of suicidal thoughts or behavior. 
  • LYRICA may cause peripheral edema. Exercise caution when co administering LYRICA and thiazolidinedione antidiabetic agents.
  • LYRICA may cause dizziness and somnolence and impair patients’ ability to drive or operate machinery

 

Contraindication

Contraindicated in patients known hypersensitivity to pregabalin or any of its components.
