Abstract - Some geriatric patients have difficulty in swallowing tablets, resulting non-compliance issues on patient. Respond from the issues, people developed an oral dosage tablet which easily become soft and rapidly disintegrate in mouth which called orally disintegrating tablet (ODT). Atenolol is one of the anti-hypertension drugs. Atenolol is classified as antagonist selective β1 receptor class that gives the effect of anti-hypertension with low bioavailability, it is necessary to change atenolol dosage forms become ODT to increased absorption of the drug in the body. To accelerate the disintegration time (less than 3 minutes) is used disintegrant sodium starch glycolate with concentration of 0% and 20%. The method that used in the tablet’s manufacture is a direct compresssion. The result of the ODT evaluation, tablet dispersion time in vitro, wetting time , water absorption ratio, and dissolution test with its parameters include (AUC, ED and kr) were analysed statistically using one way ANOVA. There a significant difference (α = 0,05) between the formulas that using sodium starch glycolate 0% and 20% in terms of tablet’s dispersion time in vitro, wetting time, water absorption ratio, dissolution test with its parameters include (AUC, ED and kr). The formula that gives the best result is the one that using 20% disintegran sodium starch glycolate because disintegration time in 19,85±0,95 seconds, tablet’s dispersion time in vitro 29,00±1,00 seconds, wetting time 23,33±1,53 seconds, water absorption ratio 555±28,45%, TQ% 1,41 minutes, the Q% 90,64±0,44%, AUC 10134,52±29,49% minutes, ED 84,45±0,27%, and kr 0,0056/minutes.

Abstract - Paracetamol is one of drugs which has low solubility property in aqueous medium. This property will affect its bioavailability. Enhancement of solubility can be achieved by formulation of solid dispersion. Paracetamol is dispersed in PEG 4000 as hydrophilic carrier with melting method. To find the effect of the amount of PEG 4000 for the solubility enhancement, two formulas of solid dispersion are made with the ratio of 1:0.5 and 1:1. After the solid dispersion formed, this formula is characterized using FTIR to determine the interactions between paracetamol and PEG 4000 as a sign of formed solid dispersion. After characterization, the amount of paracetamol in the formulationwill be measured. Lastly, dissolution test is performed to find the increase in dissolution rate compared to pure paracetamol powder. Dissolution test profile observation shows that paracetamol and PEG 4000 solid dispersion formulas have lower dissolution rate compared to pure paracetamol. Beside that, the drug content test shows that the content of paracetamol in the dosage form doesn’t meet the quality requirement as established in the Indonesian Pharmacopeia.

Formulasi Granul Effervescent Herba Meniran (Phyllanthus niruri L.) dengan Variasi Suspending Agent Xanthan Gum, CMC-Na, dan Kombinasi CMC-Na-Mikrokristalin Selulosa RC- 591 Karina Citra Rani; Nani Parfati; Deviati Muarofah; Sovia Navacatus Sacharia

Herba meniran (Phyllanthus niruri L.) merupakan simplisia tanaman obat yang selama ini digunakan masyarakat dalam bentuk air rebusan. Formulasi herba meniran dalam bentuk granul effervescent dengan penambahan suspending agent merupakan salah satu bentuk inovasi minuman fungsional. Jenis suspending agent yang digunakan dalam formula memiliki pengaruh terhadap karakteristik granul. Penelitian ini bertujuan untuk menganalisis pengaruh perbedaan jenis suspending agent xanthan gum (formula 1), CMC-Na (formula 2), dan kombinasi CMC-Na-mikroskristalin selulosa RC-591 (formula 3) dengan konsentrasi 1% terhadap karakteristik fisika dan kimia granul effervescent sebelum dan sesudah direkonstitusi. Formulasi granul effervescent herba meniran dilakukan dengan metode granulasi basah. Komponen asam dan basa digranulasi secara terpisah kemudian kedua komponen dicampur menggunakan tumbling mixer. Hasil penelitian menunjukkan bahwa granul effervescent yang dihasilkan memenuhi persyaratan dengan persentase fines sebesar 1,02-2,02%; kandungan lembap 3,76±0,13%-3,82±0,30%; kecepatan alir 7,85±0,10-10,92±0,04 g/detik; sudut istirahat 31,12±0,75-34,12±0,75°; waktu dispersi 66,95±5,50-70,26±0,03 detik; tinggi buih 3,01±0,12-3,22±0,25 cm; viskositas 222,0-242 cps; pH 6,73±0,10-6,91±0,01. Formula 1 merupakan formula terbaik karena menghasilkan waktu dispersi yang cepat, dispersi yang halus, dan viskositas yang lebih tinggi. Hasil evaluasi organoleptis dan sensori menunjukkan bahwa formula granul effervescent dalam penelitian ini dapat diterima oleh panelis.
