BUTRANS vs ROXILOX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Buprenorphine is a partial mu-opioid receptor agonist and a weak kappa-opioid receptor antagonist. It binds with high affinity to mu-opioid receptors, producing analgesic and opioid effects with a ceiling effect on respiratory depression.
Roxilox is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis and thereby alleviating pain and inflammation.
Apply one BUTRANS (buprenorphine) transdermal system to a clean, dry, non-irritated, and non-hairy area of the chest, back, flank, or upper arm. Initial dose: 5 mcg/h for opioid-naïve patients; titrate based on pain control and tolerability. Maximum dose: 20 mcg/h. Replace every 7 days. Rotate application sites.
10 mg orally once daily, with or without food.
