PREPARATION PROCESS OF UNITS OF DOSING OF LIBERTACAO SUSTAINED DRUGS, BASED ON, BETWEEN, OTHER THAN DIVALPROEX OF SODIUM, VALPROIC ACID OR TERAZOSIN AND DECOMPOSICOES OF COATING
A sustained-release coating composition is described that contains an ethylcellulose and/or a methacrylic methylester together with a plasticizer and a detackifying agent. Sized drug granules are coated with this composition and then mixed with a polymeric composition containing at least one viscosity agent and formed into drug dosage units for the administration and sustained release of the drug in a patient. The sustained-release drug dosage units described produce a continuous, slow release of the drug at a therapeutically effective dosage level when administered to a patient.
