  • Gastrointestinal irritation is the most frequent adverse effect in patients chronically taking nonsteroidal antiinflammatory drugs (NSAIDs) for the treatment of arthritic conditions. Gastroprotective effect of DA-9601, a new antiulcer agent from Artemisiae Herba extract, against NSAID was evaluated in a rat model of arthritis that is similar in many aspects to human rheumatoid arthritis. Daily oral dosing of naproxen (30 mg/kg), one of the most commonly used NSAID, induced apparent gastric lesions as well as a significant decrease in mucosal prostagiandin $E_2;(PGE_2)$ and prostagiandin F_${1{\alpha}}$$(PGF_{1{\alpha}})$ levels. Coadministration of DA-9601 prevents naproxen-induced mucosal injury and depletion of prostaglandins, in a dose-related manner. DA-9601 did not alter the antiinflammatory or analgesic effect of naproxen. The present results suggest that DA-9601 may be useful as a mucoprotectant against NSAIDs in clinical practice.

  • A various ${\alpha}$-arylmethylpropionic acids(profen) have been widely used as non-steroidal anti-inflammatory drugs for the relief of acute and chronic rheumatoid arthritis and osteoarthritis, as well as for other connective tissue disorders and pains. Example is fenoprofen, ibuprofen, ketoprofen, and naproxen. All are chiral and, except for naproxen and ibuprofen, are marketed in racemic form. Enantioseparations of profens have been of considerable interest becaus their anti-inflammatory and analgesic effects have been attirbuted almost exclusively to their (S)-enantiomer. (omitted)

  • 본 연구는 allbanggae starch (ABS), polyvinyl alcohol (PVA), alginic acid (SA)를 이용하여 naproxen (NP) 각인 starch 기반 다층 바이오소재를 제조하고, 물리화학적 특성과 약물 방출 제어 효과를 조사하였다. 또한, FE-SEM과 FT-IR 분석에 의해 제조한 다층 바이오소재의 특성을 조사하였다. 약물 방출 제어 효과와 경피 약물 전달 시스템의 적용 가능성을 확인하기 위해 NP 각인 다층 바이오소재로부터 NP 방출 특성을 사람의 체온인 36.5 ℃에서 다양한 pH buffer solution과 인공 피부를 이용하여 확인하였다. NP는 낮은 pH보다 높은 pH에서 1.3배 더 빠른 방출을 나타냈고, single-layer 바이오소재에서보다 multi-layer 바이오소재에서 약 4.0배 느린 방출이 일어남을 확인하였다. 인공 피부 방출에서도 동일하게 single-layer 바이오소재보다 multi-layer 바이오소재에서 약 4.0배 더 느린 약물 방출 결과를 나타내었다. 또한, double-layer와 triple-layer 바이오소재 모두 12시간 동안 지속적으로 NP가 방출되었음을 확인 하였다. NP 방출 mechanism을 규명하기 위해 수학적 모델링에 적용하여 비교했을 때, pH buffer solution에서의 방출은 Fickian diffusion mechanism, 인공 피부 방출은 empirical mechanism에 적합한 것을 확인하였다.
