BROMPHERIL vs DIPHENHYDRAMINE HYDROCHLORIDE PRESERVATIVE FREE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Brompheril is a mu-opioid receptor agonist with additional sigma-1 receptor antagonism, producing analgesic effects and modulating neuropathic pain.
Competitive antagonist of histamine H1 receptors; centrally acting anticholinergic agent that inhibits acetylcholine muscarinic receptors.
In adults, the usual dose is 1-2 mg/kg intravenously every 4-6 hours as needed. Alternatively, 5 mg can be administered intramuscularly or subcutaneously every 4 hours.
25 to 50 mg intravenously or intramuscularly every 4 to 6 hours as needed; maximum 400 mg per day.

Terminal half-life 2.5-4 hours; prolonged in renal impairment (up to 12 hours in severe cases).
Terminal elimination half-life: 4-10 hours (mean ~8 hours); prolonged in hepatic impairment or elderly (up to 20 hours).
Primarily renal (60-70% as unchanged drug); 15-20% fecal via biliary elimination; minor metabolic clearance.
Primarily renal as inactive metabolites; ~60% of a dose appears in urine as metabolites, with <5% unchanged. Minor biliary/fecal elimination (<10%).
