ACTIQ vs DSUVIA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Opioid agonist; binds to mu-opioid receptors in the CNS, altering pain perception and response.
Selective, high-affinity agonist at the mu-opioid receptor, resulting in analgesia via activation of G-protein coupled inwardly rectifying potassium channels and inhibition of voltage-gated calcium channels in the central nervous system.
200 mcg transmucosally, titrated upward as needed; initial dose for opioid-tolerant patients is 200 mcg, with additional doses possible after 15 minutes if needed. Maximum 4 doses per episode. At least 4 hours between episodes.
30 mcg sublingual tablet as a single dose; may repeat once after 1 hour if needed. Maximum 2 doses per 24 hours.

Terminal half-life 0.83–2 hours (mean 1.3 h) in adults; note that context: transmucosal absorption leads to rapid onset but short duration; half-life is not correlated with clinical effect due to oral transmucosal route and rapid redistribution.
Terminal elimination half-life is approximately 23.4 hours (range 17–30 h), supporting once-daily dosing. Due to rapid redistribution, clinical effects may wane before elimination is complete.
Primarily renal as metabolites (about 75% as metabolites, <10% unchanged). Fecal excretion accounts for <9%. Biliary excretion is minor.
Primarily renal elimination of metabolites; unchanged drug accounts for <1% of the dose. Fecal excretion is minimal. Total recovery: ~70% in urine, ~20% in feces.
