FINTEPLA vs KHAPZORY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fenfluramine (FINTEPLA) is a serotonin-releasing agent and serotonin receptor agonist, primarily at 5-HT2 receptors. It also acts as a sigma-1 receptor agonist and modulates GABAergic and glutamatergic transmission.
Lefamulin, a pleuromutilin antibiotic, inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, specifically to the peptidyl transferase center (PTC) at the A-site cleft, thereby blocking peptide bond formation and protein translation.
0.1-0.2 mg/kg twice daily (oral), with a maximum of 16 mg/day for patients weighing ≥50 kg; for patients <50 kg, maximum 8 mg/day.
KHAPZORY (lenalidomide) 25 mg orally once daily on days 1-21 of repeated 28-day cycles.
