Description
Invention field
The present invention relates to a kind of pharmaceutical preparation for the treatment of epilepsy and preparation method thereof, belong to the medication of neurosurgery class disease, be specifically related to a kind of oxcarbazepine controlled release tablet and preparation method thereof.
Background of invention
Oxcarbazepine belongs to benzene diaza leather class medicine, is worldwide registered as antuepileptic.Oxcarbazepine goes through as being used for the treatment of adult and child's partial seizure and ancillary drug or the monotherapy of complete tetanus-clonic epilepsy outbreak.Oxcarbazepine releases (IR) dosage form with commodity masterpiece in music Lay at present
sell, use every day and control epilepsy twice.This compositions of releasing provides medicine to patient in some way, causes plasma drug level to rise rapidly, then declines rapidly.The sharp change of this drug level may cause side effect, and must every day repeatedly drug administration, to keep medicine treatment level in vivo.For the medicine of long-term taking as the controlled release form of oxcarbazepine and derivant need to be self-evident.Use controlled release (CR) dosage form of taking for example every day once greatly to improve patient compliance.And, use controlled release form to have obvious clinical advantages, for example the better side effect of therapeutic effect and minimizing.
Oxcarbazepine and derivant thereof that the present invention considers are slightly soluble in water.Poorly soluble due to them, their release from Slow release dosage form is quite incomplete.Although the vitro release of oxcarbazepine depends on dissolving-out method, comprise dissolution medium used, to find by microcomputer modelling, in the body of oxcarbazepine from conventional Slow release dosage form, release is quite low.The declined bioavailability of oral administration that this causes medicine, makes dosage form can not provide in vivo treatment effective concentration.This has proposed stern challenge for the Slow release dosage form of successfully developing oxcarbazepine and derivant thereof.
The rate of release of medicine from dosage form has appreciable impact for treatment serviceability and the side effect thereof of medicine.The Slow release dosage form of oxcarbazepine and derivant has been described in this area.Franke etc. (US20040142033) disclose the Slow release dosage form of oxcarbazepine, it is characterized in that in 15 minutes, discharging 55%-85% medicine, and in 30 minutes, discharge high to 95% medicine.Described in author, these release profiles provide sufficient Slow to release to obtain and have used oxcarbazepine every day one time.But the dissolubility and the bioavailability that strengthen the medicine of preparation from these are applicable to using once every day.
The object of this invention is to provide a kind of can constant release medicine and the stability of medicine release and the higher oxcarbazepine controlled release tablet of the safety of medication, it is characterized in that being formed by oxcarbazepine and the physiologically acceptable pharmaceutic adjuvant of effective therapeutic dose, can constant release at different release medium Chinese medicines.The features such as controlled release tablet of the present invention has that convenient drug administration, effect are lasting, stable curative effect, toxic and side effects are little.
