Abstract

Kencur (Kaempferia galanga L.) is a family of Zingiberaceae. Several studies have shown that kencur can help reduce inflammation because kencur is known to contain anti-inflammatory compounds, namely marker compounds from flavonoids, kaempferol. For the development of pharmaceutical preparations, research on anti-inflammatory plasters containing 96% ethanol extract, n-hexane extract, ethyl acetate extract and 70% ethanol extract from ginger rhizome with the addition of penetration enhancer (enhancer), namely propylene glycol. This anti-inflammatory plaster was tested for its activity in 5 groups of Wistar strain rat feet which had been induced 1% carrageenan (negative control); positive control (diclofenac sodium), ethanol96% extract, n-hexane extract, ethyl acetate extract and 70% ethanol extract from kencur rhizome and compared with plaster of kencur rhizome ethanol extract without enhancer. The results showed the effect of adding enhancers 30 minutes after administration. 96% ethanol extract and ethyl acetate extract had reduced inflammation by 79.99% in rat test animals compared to plaster ethanol extract of rhizome kencur without the addition of enhancers. Keywords :  Kaempferia galanga.

Abstract

Anredera cordifolia or binahong is one of the Indonesian medicinal plants that is used to treat peptic ulcer. The purpose of this study was to evaluate the effect of the addition of sodium carboxymethylcellulose (CMC) and sorbitol on anti-peptic ulcer activity of A. cordifolia leaves extracts in male Wistar rats. The plants were extracted using decoction method and freeze dried. Three liquid formulas were used i.e., i) a combination of sodium CMC and sorbitol; ii) only sorbitol; iii) extract only. The rats were divided into 6 groups, i.e., positive control (sucralfate 35 mg/kg body weight); negative control (80% ethanol); normal control; and 3 formulas. After the administration of the liquid formula, all groups, except normal control, were given 80% ethanol (l5 ml/kg body weight) to induce peptic ulcer. Antipeptic ulcer activity was evaluated using direct observation on rats gastric mucosa, and histopathology assessment. The result showed that the strongest anti-peptic ulcer  was shown by sorbitol only (96.95% inhibition),  followed by the combination of sodium CMC and sorbitol (92.68% inhibition). The formula which only contained extract showed only  31.70% inhibition.  Statistical analysis showed significant differences between formula 1 and 2 with negative controls. In conclusion, A. cordifolia leaves extract with the addition of sorbitol showed the strongest anti-peptic ulcer activity. Keyword: Anredera cordifolia, peptic ulcer, suspense, Wistar rat.

Abstract

Kelarutan merupakan faktor fisikokimia penting yang mempengaruhi bioavailabilitas dan efektivitas terapi obat. Sekitar 40% atau lebih dari kandidat obat yang tersedia memiliki kelarutan yang rendah dalam air sehingga kelarutan dari zat aktif perlu ditingkatkan agar bioavailabilitasnya ikut meningkat, salah satunya dengan cara teknik kokristalisasi. Dalam studi ini akan dikemukakan review terkait pengaruh pembentukan kokristal zat aktif yang memiliki kelarutan rendah dalam air menggunakan koformer golongan asam karboksilat dengan metode solvent evaporation dan solvent drop grinding terhadap peningkatan bioavailabilitas. Zat aktif yang berhasil dibuat kokristal dengan peningkatan bioavailabilitas menggunakan koformer golongan asam karboksilat dengan metode solvent evaporation yaitu apixaban, aceclofenac, klorbipram, telmisartan, paliperidon, dan metronidazol, sedangkan untuk metode solvent drop grinding diantaranya ketokonazol, meloksikam, dipfluzin, asam galat, gliclazid, dan itrakonazol. Berdasarkan kajian pustaka, dapat disimpulkan bahwa pembentukan kokristal menggunakan koformer golongan asam karboksilat dengan metode solvent evaporation dan solvent drop grinding berpotensi meningkatkan bioavailabilitas zat aktif. Peningkatan terjadi karena terbentuk ikatan hidrogen antara zat aktif dengan koformernya serta adanya fase kristal baru yang menandakan kokristal telah terbentuk dan mengindikasikan peningkatan kelarutan sehingga bioavailabilitasnya ikut meningkat. Kata kunci: Bioavailabilitas, kokristal, koformer golongan asam karboksilat, kokristal, solvent drop grinding, solvent evaporation.
