LAROTID vs PENICILLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Larotrectinib is a selective inhibitor of tropomyosin receptor kinase (TRK) A, B, and C. It inhibits TRK kinase activity by binding to the ATP-binding site, leading to inhibition of downstream signaling pathways, which results in reduced cell proliferation and tumor growth in tumors with NTRK gene fusions.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activation, leading to cell lysis.
Larotrectinib 100 mg orally twice daily, with or without food, for adult patients.
Penicillin G: 2-4 million units IV every 4-6 hours; Penicillin V: 250-500 mg orally every 6 hours for mild to moderate infections.

Clinical Note
moderateBenzylpenicillin + Teriflunomide
"The serum concentration of Teriflunomide can be increased when it is combined with Benzylpenicillin."
Clinical Note
moderateBenzylpenicillin + Acemetacin
"Benzylpenicillin may decrease the excretion rate of Acemetacin which could result in a higher serum level."
Clinical Note
moderateProcaine benzylpenicillin + Acemetacin
"Procaine benzylpenicillin may decrease the excretion rate of Acemetacin which could result in a higher serum level."
Clinical Note
moderate30 minutes; prolonged in renal impairment (up to 20 hours in anuria).
0.5-1.0 hours in normal renal function; prolonged to 7-10 hours in anuria. Dose adjustment required in renal impairment.
Renal: 70-80% unchanged by glomerular filtration and tubular secretion; Biliary/Fecal: <10% as inactive metabolites.
Primarily renal (60-80% unchanged via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for 10-20%.
