Abstract
Fluconazole has been used to treat acute vaginal candidiasis, systemic candidiasis and oral pharynx, esophagus, invasive bronchopulmonary infection and candidiasis urine disease, hand · nail fungus, athlete's foot (foot ringworm). The solubility of fluconazole needs to be improved to be efficiently usedasan antifungal agent, since it has low solubility in water. To improve solubility of fluconazole, solid dispersion technique was used using various polymers as carrier. The polymer used in this study include poly ethylene glycol (PEG 8000), poIyethyleneglycol (PEG20000), hydroxypropylmethylcellulose (HPMC2910), polyvinylpyrrolidone (PVP K-30), polyvinylpyrrolidone (PVP K-90), copovidone K-28, poloxamer188, poloxamer407, EUDRAGIT®S100, EUDRAGIT®EPO,EUDRAGIT®L100. The solubility of physical mixture and solid dispersion was measured in water, pH 1.2 phosphate buffer, and pH 6.8 phosphate buffer. Dissolution experiments were also conducted using same medium. The solubility test results indicated that poIy ethylene glycol(PEG8000), hydroxypropylmethylcellulose (HPMC2910), copovidone K-28, poloxamer188, poloxamer407 can improve the solubility of fluconazole better than other polymers.
Result of Differential scanning calorimetry (DSC) study showed that fluconazole was converted to amorphous form by solid dispersion. Based on DSC analysis and solubility test results, copovidone K-28 polymer was selected for further study. The solid dispersion of fluconazole using copovidone K-28 (1:2) showed similar dissolution rate with that of commercial diplucan capsule (fluconazole 50 mg).
The results of this study indicated that copovidone K-28 was the most efficient carrier to preparesolid dispersion of fluconazole.|급성 질칸디다증, 전신 칸디다증 및 구강 인두, 식도, 침습성 기관지 폐감염과 칸디다뇨증, 손·발톱진균증, 무좀(족부백선) 등 치료에 사용되는 플루코나졸 은 물에서 낮은 용해도를 나타내며 항진균제로 사용하기 위해서는 용해도가 향상 되어야 한다. 그러므로 본 연구에서는 플루코나졸의 용해도를 향상시키는 polymer를 검색하고 고체 분산체를 이용하여 플루코나졸의 용해도를 향상 시키고자 하였다. 플루코나졸의 용해도 향상을 위해 polymer로 poIyethyleneglycol (PEG 8000), poIyethyleneglycol (PEG 20000), hydroxypropyl methylcellulose (HPMC2910), polyvinylpyrrolidone (PVP K-30), polyvinyl pyrrolidone (PVP K-90), copovidone K-28, poloxamer188, poloxamer407, EUDRAGIT®S100, EUDRAGIT®EPO, EUDRAGIT®L100 을 사용하여 물과 pH1.2, pH6.8에서 용해도 실험을 하였다.
고체 분산체를 제조하여 용해도 실험 결과 poIyethyleneglycol (PEG8000), hydroxypropylmethylcellulose (HPMC2910), copovidone K-28, poloxamer 188, poloxamer 407의 5가지 polymer의 용해도가 향상 되었다.
Differential scanning calorimetry(DSC) 결과는 고체 분산체를 제조한 플루코나졸과 polymer가 무정형 상태임을 나타내었다. 용해도 실험 및 DSC 분석 실험 결과 용출 실험에 플루코나졸과 고체 분산체를 이용하여 용해도를 높이는데 사용할 polymer로 copovdone K-28을 선택하였다. CopovidoneK-28을 이용하여 플루코나졸의 고체 분산체를 1:2의 비율로 제조하였다. “화이자”에서 개발된 디푸루칸캡슐 (플루코나졸50mg)과 고체 분산체를 이용하여 제조 된 실험 샘플을 가지고 물, pH1.2, pH6.8액에서 용출율을 비교 실험하였으며 샘플은 모든 액에서 용출 실험을 시작 후 30분 정도에 모든 용출이 완료 되었다.
본 연구결과는 고체 분산체를 이용한 copovidone K-28은 플루코나졸의 용해도와 용출율을 향상 시키는데 효과적이었다.
