Monoammonium glycyrrhizinate was determined it has anti-viral activity in case of hepatitis A, B, C, D. We have developed matrix tablet contained monoammonium glycyrrhizinate by previous study. The objective of the study was to evaluate drug release of matrix tablet in vivo and determinate its stability. In the present study was evaluated in vivo drug release of the matrix tablet. Stability testing was 230 determinated by long term and accelerated method by such criteria's: appearance, weight variation, biological active compound, hardness, friability, dissolution and microbiological contamination. The Cmax (µg/ml), Tmax (h), AUC0-t (µg h/ml) of Glycyron tablet and Licozinat matrix tablet were determined in vivo. Stability of the matrix tablet was determined. Licozinat matrix tablet was released drug by prolonged time by in vitro. In vivo pharmacokinetic study in rabbits confirmed the prolonged release by showing increase in bioavailability for matrix tablet compared to Glycyron tablet. Licozinat matrix tablet was stable for 12 months. Stability testing of matrix tablet is continuing by long term method.
Monoammonium glycyrrhizinate of Glcyrrhiza root has been used as an expectorant, detoxificator, anti-allergic, and antioxidant. Japanese researchers have been determined its anti-hepatitis A, B, C, D viruses activity. Therefore, we isolated mono-ammonium glycyrrhizinate from Glycyrrhiza root, grown in Mongolia and developed controlled release matrix tablet. Appropriate excipients were chosen for matrix tablet: lactose as a diluent, 5% of PVP-K30 as a binder, HPMC as a matrix former, 3% of talc and 1% of magnesium stearate as a glidiant or lubricant. We prepared matrix tablet by wet granulation method and pressed by 2.5 kPa pressure. Formulation 5 (F5) was determined the most qualified tablet design and it released drug constantly in vitro. For the determining of hepatoprotective effect, we studied influence on hepatocytolis of preparation in vivo by the histological method. Results of the study showed that the Licozinat matrix tablet was appropriate at a 52 mg/kg dose once daily. Ликозинат матрикс шахмалын чанарын болон элэг хамгаалах үйлдлийн судалгаа Хураангуй: Чихэр өвсний үндсэнд агуулагдах моноаммонийн глициризинат нь цэр ховхлох, хордлого тайлах, харшлын эсрэг, антиоксидант үйлдэлтэй. Японы эрдэмтдийн судалгаагаар моноаммонийн глициризинат нь элэг хамгаалах болон А, В, С, D вирүсээр үүсгэгдсэн элэгний үрэвсэлд вирүсийн идэвхжлийг саатуулдаг нь тогтоогдсон байна. Бид өөрийн оронд ургадаг Уралын чихэр өвсний үндэснээс моноаммонийн глицирризинатыг цэврээр ялган авч эмчилгээний өндөр ач холбогдол бүхий матрикс хэлбэрийн шахмал гарган авч практикт нэвтрүүлэх нь зүйтэй гэж үзлээ.Бид эмийн бодисоо зохицуулалттай чөлөөлдөг матрикс шахмалын тохирох дүүргэгч бодисоор лактоз, холбогч бодисоор PVP-K30 5% концентрациар, матрикс үүсгэгчээр НРМС, гулсуулагч тослох бодисоор тальк 3%, магнийн стеарат 1%-ийн холимгийг сонгох нь тохиромжтой болохыг тогтоов.In vitro нөхцөлд эмийн бодисын чөлөөлөгдөлтийг тодорхойлоход F5 загварын шахмал нь эмийн бодисоо жигд хурдтайгаар чөлөөлж байв. Туршилтын амьтанд in vivo нөхцөлд бэлдмэлийн элэг хамгаалах үйлдлийг элэгний эсийн задралд хэрхэн нөлөөлж буй болон гистологийн аргаар судлахад Ликозинат матрикс шахмал эмийг 52 мг/кг тунгаар өдөрт нэг удаа уулгах нь тохиромжтой болохыг тогтоолоо. Түлхүүр үгс: Чихэр өвс, моноаммонийн глицирризинат, матрикс шахмал, элэг хамгаалах идэвх
