JAYPIRCA vs TECHNESCAN HIDA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
JAYPIRCA (pirtobrutinib) is a selective, non-covalent (reversible) inhibitor of Bruton's tyrosine kinase (BTK). It binds to BTK, inhibiting its kinase activity, thereby blocking B-cell receptor signaling and reducing proliferation and survival of malignant B cells.
Technetium Tc-99m mebrofenin is a radiopharmaceutical that, after intravenous administration, is taken up by hepatocytes via organic anion transporting polypeptides (OATPs) and excreted into the bile canaliculi via multidrug resistance-associated protein 2 (MRP2). It allows scintigraphic evaluation of hepatobiliary function by emitting gamma radiation detectable by a gamma camera.
The recommended adult dose is 15 mg orally once daily, with or without food.
5 mCi (185 MBq) administered intravenously as a single dose for hepatobiliary imaging.

Terminal half-life approximately 15-20 hours in adults with normal renal function; prolonged in renal impairment (up to 30-40 hours in severe impairment).
Terminal elimination half-life is approximately 1.5 hours (range 1-2 hours) in patients with normal hepatic function. In patients with hepatic impairment, half-life may be prolonged up to 4-6 hours.
Primarily renal (80-90% as unchanged drug and minor metabolites); fecal <5%.
Primarily biliary excretion: 85-90% of administered dose is excreted into bile via the hepatobiliary system within 2 hours, with minimal renal elimination (<5%) and fecal excretion accounting for <2%.
