JAYPIRCA vs TECHNETIUM TC 99M SESTAMIBI
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 sestamibi is a cationic lipophilic complex that passively diffuses across cell membranes and accumulates in mitochondria due to the negative mitochondrial membrane potential. It is used as a myocardial perfusion imaging agent to visualize blood flow to the heart muscle.
The recommended adult dose is 15 mg orally once daily, with or without food.
Myocardial imaging: 740-1110 MBq (20-30 mCi) IV bolus, single dose. Parathyroid imaging: 740-925 MBq (20-25 mCi) IV bolus, single dose.

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: approximately 6 hours (range 4–8 hours) for myocardial clearance. Delayed clearance may occur in patients with hepatic or renal impairment.
Primarily renal (80-90% as unchanged drug and minor metabolites); fecal <5%.
Primarily renal: approximately 33% of injected dose excreted in urine within 8 hours, increasing to about 50% by 24 hours. Hepatic uptake with subsequent biliary excretion accounts for the remainder; fecal elimination is less than 2% of administered dose.
