A study on mucoadhesive properties of ketoprofen â PVP K-30 solid dispersion granules using chitosan had been done. Solid dispersion of ketoprofen and PVP K-30 was made at ratio 1:1 using solvent method. Granules were made by wet granulation method at various concentrations of chitosan (10%, 20% and 30%). The granules were evaluated including photomicroscopy, flow rate, angle slides, water content, particle size distribution, dissolution test, in-vitro test bioadhesif and wash off test. The release of ketoprofen from the granules was determined using basket dissolution test in pH 7.5 phosphate buffer medium for 8 hours. Mucoadhesive properties were tested by in-vitro bioadhesif tests and wash off test. The dissolution test showed the dissolution effeciency value of formula 1, 2, and 3, respectively, was 78.9890 Â± 1.1398; 77.3889 Â± 1.4312, and 75.8869 Â± 0.2210 %. Results showed a decrease in the release of the active substance from the granules, with the increase in chitosan concentration. Statistical analysis of the efficiency of dissolution showed a significant difference among the three formulas with (P <0.05). In vitro bioadhesif tests showed that granules were able to attached to the stomach and intestinal mucosa of rabbits.

Solid-state interaction between parasetamol and ibuprofen was studied using thermal and spectroscopic techniques. Parasetamol-Ibuprofen binary mixtures were prepared by rotary ball mill grinding method. Differential scanning calorimetry was used to investigate the stoichiometry and thermal properties of the complex between parasetamol and ibuprofen. Powder X-ray diffraction were used to investigate the type of interaction between the two components. Two endothermic peaks in a binary mixture of paracetamol and ibuprofen was observed in DSC thermograph. X-ray powder diffractogram do not shows shift and formation of new peaks and the position of each peak is a super-imposition of each component without dominates. It can be concluded that the solid interaction between paracetamol and ibuprofen for grinding effect is the formation of mixed crystal system.

ABSTRAK Ibuprofen merupakan kelompok obat anti inflamasi non steroid yang mempunyai efek antiinflamasi, analgetik dan antipiretik. Penggunaannya sebagai antipiretik semakin meningkat di masyarakat. Pada sediaan farmasi, obat-obat antipiretik sering dikombinasikan penggunaannya bersama kafein. Penelitian ini bertujuan untuk mengetahui perbandingan efek antipiretik dari ibuprofen murni dengan campuran ibuprofen dan kafein. Penelitian ini menggunakan 15 ekor tikus putih jantan berumur 2-3 bulan yang dibagi menjadi 3 kelompok uji. Kelompok I diberi Na-CMC 1% dan larutan pepton 5%. Kelompok II diberi Ibuprofen murni dosis 5,4 mg/ 200 gram BB dan larutan pepton 5%. Kelompok III diberi Campuran Ibuprofen : Kafein ; 0,4 : 0,6 dosis 5,4 mg/ 200 gram BB dan larutan pepton 5%. Pengukuran suhu dilakukan sebelum pemberian larutan pepton, 3 jam setelah pemberian larutan pepton, dan tiap 30 menit setelah perlakuan hingga menit ke 150 menggunakan termometer digital. Data penurunan suhu dianalisa secara statistik menggunakan uji ANOVA dan uji lanjut duncan. Hasil penelitian menunjukkan adanya perbedaan secara bermakna (p < 0,05) pada penurunan suhu antara ibuprofen murni dengan campuran ibuprofen dan kafein, ini artinya efek antipiretik campuran ibuprofen dan kafein lebih tinggi dibandingkan dengan ibuprofen murni.

Publisher : Fakultas Farmasi Universitas Andalas

Tujuan dari penelitian ini adalah untuk melihat pengaruh penggilingan pada asiklovir terhadap sifat fisikokimia dan penetrasi dari cream asiklovir. Penggilingan asiklovir menggunakan alat ball mill dengan variasi lama penggilingan 1, 3 dan 6 jam. Asiklovir kemudian diformulasikan menjadi cream dan dilakukan evaluasi sifat fisikokimia dan penetrasinya. Sebagai pembanding digunakan basis cream tanpa zat aktif dan cream asiklovir yang sudah beredar. Uji pelepasan dilakukan dengan menggunakan sel difusi Franz jenis horizontal dan kadar asiklovir yang terpenetrasi diukur menggunakan Spektrofotometer UV-Vis dengan panjang gelombang serapan maksimum 254 nm. Hasil penelitian menunjukkan bahwa sediaan cream yang dihasilkan homogen, dengan pH antara 7-7,5, type cream M/A, Sediaan cream mudah tercuci dan tidak menyebabkan iritasi. Proses penggilingan 1 dan 3 jam menyebabkan terjadinya penurunan ukuran partikel sehingga meningkatkan jumlah asiklovir yang terpenetrasi, sedangkan penggilingan 6 jam menyebabkan terbentuknya agregat dengan ukuran partikel lebih besar, sehingga menyebabkan jumlah asiklovir yang terpenetrasi lebih rendah dibandingkan cream asiklovir tanpa penggilingan. Proses penggilingan terhadap asiklovir tidak mempengaruhi sifat dari cream tapi semakin lama proses penggilingan menyebabkan penurunan jumlah zat yang terpenetrasi

Paracetamol was an active ingredient, which is poorly soluble in water. Absorption of poorly soluble or slightly soluble in water is influenced by the rate of dissolution. Solubilization is an alternative to improve drug solubility in water with the addition of surfactant. The addition of Ryoto® sugar ester surfactant and propylene glycol cosolvent conducted to determine the concentration of Ryoto® sugar ester and prophylene glycol that increase the solubility and stability of the dosage form. Solubilization of Paracetamol with the addition of Ryoto® sugar ester without propylene glycol and combinations Ryoto® sugar ester and propylene glycol at a concentration below the CMC point (Critical Micell Concentration), at the point of CMC, and above the CMC points in a row is 0.005 mg/ml, 0.006 mg/ml, and 0.007 mg/ml with 10% propylene glycol. The highest solubility of Paracetamol achieved in the formula 7 with a combination of the addition Ryoto® sugar ester (0.007 mg/ml) and propylene glycol (10%) by the recovery percentage of 99.6%, and the combination is also obtained the best preparation stability which is not occur the color change in the preparations during storage at room temperature and place protected from direct sunlight for a month. The addition of Ryoto® sugar ester surfactant and propylene glycol increase the solubility and stability of the solubilization of Paracetamol preparations.

This study aimed to improve the solution of usnic acid, a poorly soluble drug using solid dispersions (SDs). The SDs were prepared by a freeze-drying technique with poloxamer 188 as a polymer. The physicochemical properties of the SDs were characterized using X-ray diffractometry (XRD) and Fourier transform-infrared (FT-IR) spectroscopy, Scanning Electron Microscopy (SEM),. In addition, drug content, solution test and dissolution profile was evaluated by using usnic acid (pure drug) and physical mixture as a reference. The results from XRD and SEM showed that usnic acid was molecularly dispersed in the SDs as an amorphous form. The FT-IR results suggested that intermolecular hydrogen bonding had formed between usnic acid and its carriers. The result of solubility test showed that solubility of solid dispersions 1:1; 1:2; 2:1 (5.80 µg/ml; 6.94 µg/ml ; 4.88 µg/ml) were higher than the physical mixture 1:1 ( 0.39 µg/mL) and pure asam usnat have the lowest solubility (0.34 µg/mL). In conclusion, SDs prepared by a freeze-drying technique used poloxamer as a polymer can be used to enhance solubility of usnic acid
