ALFENTA vs DILAUDID
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
μ-opioid receptor agonist that activates G-protein coupled receptors to inhibit adenylate cyclase, decreasing cAMP production, leading to reduced neuronal excitability and pain transmission.
Dilaudid (hydromorphone) is a full opioid agonist with high affinity for mu-opioid receptors, producing analgesia by mimicking endogenous endorphins and enkephalins. It also activates kappa and delta opioid receptors to a lesser extent.
Intravenous: Initial dose 8-20 mcg/kg (0.5-1 min) then 0.5-3 mcg/kg/min or 3-5 mcg/kg q5-20min. For short procedures: 8-20 mcg/kg. For longer procedures: 50-75 mcg/kg followed by 0.5-3 mcg/kg/min.
Initial: 2-4 mg orally every 4-6 hours as needed; or 1-2 mg intramuscularly, subcutaneously, or intravenously every 4-6 hours as needed.
