A single-lever cartridge for a sanitary faucet for adjusting the temperature and/or quantity of mixed water by means of a swivel lever (3), having a control disk arrangement (5), which has a stationary control disk (6) disposed in a stationary position in the cartridge, in which a cold-water inlet and a hot-water inlet (27, 29) and a mixed-water outlet (31) are formed, and a dynamic control disk (8) displaceable by means of the swivel lever (3), in which a recess (33) is formed, which is disposed in different overlaps with the cold-water inlets and hot-water inlets (29, 27) and the mixed-water outlet (31) to adjust the temperature and/or quantity of the mixed water fed from the mixed-water outlet (31) of the stationary control disk (6), wherein the two control disks (6, 8) are in sliding contact with sealing surfaces (35, 37) facing each other at a sealing plane (DE), and wherein the mouths (39) of the cold-water inlets and hot-water inlets (29, 27) are formed in the sealing surface (35) of the stationary control disk (6), which mouths can be covered by the sealing surface (37) of the dynamic control disk (8). According to the invention, the cartridge has a throttling element (41) designed as a separate component, which can be used to reduce a flow cross-section of the mouths (39) of the cold-water inlets and the hot-water inlets (29, 27), for throttling the hot-water flow and/or cold-water flow into the recess (33) of the dynamic control disk (37).
