SUBSYS vs TRAL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
SUBSYS (fentanyl) is a mu-opioid receptor agonist that produces analgesia by mimicking endogenous opioids, increasing potassium efflux and reducing calcium influx, thereby inhibiting neuronal transmission of pain signals.
Tralokinumab is a human monoclonal antibody that specifically binds to interleukin-13 (IL-13) and inhibits its interaction with the IL-13 receptor α1 and α2 subunits. This blockade reduces IL-13-mediated signaling, which is implicated in the pathophysiology of atopic dermatitis, including inflammation, pruritus, and skin barrier dysfunction.
SUBSYS (fentanyl buccal soluble film) is indicated for breakthrough pain in opioid-tolerant patients. Initial dose: 100 mcg (one 100 mcg film) placed on the inner cheek, allowed to dissolve over 15-25 minutes; may repeat once after 30 minutes if pain not relieved. Titrate to effective dose (200, 400, 600, 800, 1200, 1600 mcg). Maximum: 4 doses per day. No more than 2 doses per breakthrough pain episode. Wait at least 2 hours before treating next episode.

Clinical Note
moderateSertraline + Desmopressin
"The risk or severity of adverse effects can be increased when Sertraline is combined with Desmopressin."
Clinical Note
moderateSertraline + Tenofovir disoproxil
"The metabolism of Tenofovir disoproxil can be decreased when combined with Sertraline."
Clinical Note
moderateSertraline + Sulfisoxazole
"The metabolism of Sulfisoxazole can be decreased when combined with Sertraline."
Clinical Note
moderateSertraline + Cyclosporine
Terminal half-life 2–4 hours (single dose); prolonged to 7–15 hours in hepatic/renal impairment; clinical context: necessitates q4–6h dosing for chronic pain.
Terminal elimination half-life is 12–18 hours in patients with normal renal function (CrCl >90 mL/min). In moderate renal impairment (CrCl 30–59 mL/min), half-life extends to 24–36 hours. Clinical context: Dosing interval adjustment required for CrCl <60 mL/min.
Primarily renal (~75% as metabolites, <10% unchanged); biliary/fecal excretion of conjugates; ~9% in feces.
Approximately 70% of the dose is excreted unchanged in urine via glomerular filtration and active tubular secretion; 30% is eliminated in feces via biliary secretion. Total renal clearance accounts for 85% of systemic clearance.
