The invention provides a melogabalin besylate
composite pulse drug release preparation and a preparation method thereof, and belongs to the technical field of pharmaceutical preparations. The melogabalin besylate
composite pulse drug release preparation provided by the invention comprises a composite tablet and a
film coating coated on the surface of the composite tablet, wherein the composite tablet comprises a slow release layer and a pulse-quick release layer which are laminated; the sustained-release layer is formed by
drug-containing sustained-release particles; the pulse-quick release layer is formed by drug-containing pulse
pellets and drug-containing quick release particles; the drug-containing pulse pellet comprises a drug-containing pellet core, an
isolation layer coating the surface of the drug-containing pellet core, a time-
lag layer
coating the surface of the
isolation layer and an enteric layer
coating the surface of the time-
lag layer. The melogabalin besylate
composite pulse drug release preparation provided by the invention can realize stable and effective release of drugs in the
daytime and high-concentration release at night, and can avoid the saturated absorption problem and improve the overall
bioavailability at the same time.
