Background. Tramadol hydrochloride is a novel, centrally acting analgesic w
ith two complementary of action: opioid and aminergic First marketed in 199
4, tramadol is frequently prescribed by physicians for the management of mo
derate-to-moderately severe chronic pain; The author evaluates its unique a
nalgesic pharmacology and limited clinical utility for managing acute pain
in denistry.
Types of Studies Reviewed. Clinical drug trials in medicine and dentistry w
ere reviewed to assess analgesic efficacy. Postmarketing surveillance studi
es and reports of adverse drug events were evaluated to determine short-and
long-term safety.
Results, Tramadol's maximum analgesic efficacy for relieving acute pain aft
er oral surgery appears to be similar to that of 60 milligrams of codeine a
lone but less than that of a full therapeutic dose of a nonsteroidal anti-i
nflammatory drug or a codeine combination, such as aspirine/codeine or acet
aminophen/codeine. Adverse events reported by patients receiving tramadol t
herapy since it was approved by the Food and Drug-Administration suggest a
risk of seizures, drug abuse and anaphylactoid reactions.
Clinical Implications. Tramadol has limited indication for management of ac
ute pain in dentistry, possibly as an alternative analgesic when gastrointe
stinal side effects contraindicate the use of nonsteroidal anti-inflammator
y drugs and when codeine/acetaminophen combination analgesics are not well-
tolerated or are contraindicated.
