Maltodextrin utilization of topioca strarch as a film coating on amoxyllin tablet: Maltodextrin is produced by hydrolized of strach used enzyme or acid, that reduced the amount of sugar 20 maximal .In this research,maltodextrin DE 5 to 10 was made from tapioca starch (Manihot utillissima Pohl) by using Temamyl L-120 Novo enzyme as a-amylase at 85 oC for 65 minute.Maltodextrin De 5 to 10 with particlesize 60 mesh (250 um) was used as fil coating on amoxycillin tablet in order to reduce a bad smell .AS a standard of coating was used pharmacoad 645w. The coating tables were evaluated according to Fi III an IV included visual test. Weight uniformity, size uniformity, hradness, friability,desintegration time, dissolution test and smell test.The result of this research showed that maltodextrin DE 5-10 from tapioca starch fulfill the terms above. The best formula is maltodextrin 10 %, PEG 400 5% and Na Alginat 5% from polymer weight.

Nanopartikel dapat dibuat dengan menggunakan beberapa metode dan metode gelasi ionik adalah yang termudah. Verapamil hidroklorida adalah obat yang digunakan sebagai antiaritmia, antiangina, dan terapi antihipertensi. Namun demikian, bioavailabilitas dari verapamil yang diberikan secara oral sangat rendah, hanya sekitar 10 hingga 23%. Oleh karena itu, verapamil hidroklorida ini dibuat sebagai sediaan nanopartikel untuk meningkatkan bioavailabilitasnya. Tujuan dari penelitian ini adalah untuk mengoptimalkan metode gelasi ionik antara kitosan dan natrium tripolifosfat guna mendapatkan formulasi nanopartikel terbaik. Nanopartikel diperoleh dari empat metode yang berbeda (formula A, B, C, dan D). Distribusi ukuran partikel, potensial zeta, efisiensi penjerapan, morfologi, dan spektrum FT-IR dari nanopartikel dikarakterisasi. Formula yang dipilih adalah formula D yang memiliki ukuran 62,8 nm, efisiensi penjerapan 59,15%, potensial zeta 25,46 mV, bentuk bulat, dan memiliki spektrum FT-IR yang sesuai. Hasil penelitian menunjukkan bahwa kitosan-tripolifosfat dapat menghasilkan nanopartikel verapamil hidroklorida dengan menggunakan metode gelasi ionik.

Nanoparticles can be prepared by several methods and the ionic gelation method is the easiest one. Verapamil hydrochloride is a drug which used as antiarrhythmic, antiangina, and antihypertension therapy. Nevertheless, bioavailability of orally administered verapamil is very low, only about 10 to 23%. Therefore, verapamil hydrochloride was prepared as nanoparticles dosage form to increase its bioavailability. The purpose of the present study was to optimize ionic gelation method of chitosan and sodium tripolyphosphate to obtain the best nanoparticles formulation. Nanoparticles were obtained from four different methods (formula A, B, C, and D). Particle size distribution, zeta potential, entrapment efficiency, morphology, and fourier transform infra red spectrum of each nanoparticles formula were characterized. The chosen formula was formula D which has 62.8 nm of size, 59.15% of entrapment efficiency, +25.46 mV of zeta potential, spherical shape, and the ionic interaction was confirmed by FT-IR spectrum. The results showed that chitosan-tripolyphosphate succesfully produce the verapamil hydrochloride nanoparticles by ionic gelation method.
