  In the present study the cost of the drugs used by 233 patients with chronic pain (117 with nociceptive pain, 59 with neuropathic pain, and 57 with mixed pain) followed at the Alpha Center of UNIFESP between January 2004 and January 2008 was evaluated.
  
  
  RESULTS
  The mean general cost was R$ 127.74 (from R$ 5.00 to R$ 780.00).
