A university hospital located in Kyungbuk province was chosen for this study. The drug use pattern was analyzed in terms of ingredient, administration route, patient type, and attending department. Amount of drug usage was counted by unit dose defined by the number of ampule or vial for injectable, tablet or capsule for oral, and each for patch preparations. Result showed that 11 narcotic analgesic ingredients were used during 2007-2009, and the drug usage was increased by about 20% annually during the period. Proportion of oral preparations used for pain management was about two third of all narcotic analgesics usage and kept increasing during the period. Proportion of the drug usage for outpatients was also steadily increased. Notably, the usage of oral preparations of oxycodone, morphine, and hydromorphone was rapidly increased for the management of cancer pain while the usage of codeine and codeine-containing composite preparations for cancer pain were minimal (<10%). About 90% of all narcotic analgesics were used by physicians in Internal Department, especially in Oncology Division of the Department. These findings suggest that pain management is becoming more aggressive and in agreement with WHO's guidelines regarding selection of administration route. However, in terms of 3-step ladder for cancer pain management, the drug use pattern was not congruent to WHO's guidelines. Therefore, in conclusion, it appears that physicians need to try to be congruent to the guidelines when using narcotic analgesics for cancer pain.

Fig. 5. Drug use pattern of all narcotic analgesics by admission status. 최근 3년 동안 내과에서 사용된 마약성 진통제의 양은 모두 667,911 dose로서 병원 전체 사용량 955,477 dose의 69.9% 를 차지했다. 특히 morphine HCl, morphine sulfate, codeine phosphate, oxycodone, fentanyl patch 등은 90% 이상이 내과 에서 사용되었다. Pethidine은 정형외과(28.6%), 일반외과 (28.0%), 내과(14.7%), 신경외과(8.9%), 산부인과(6.0%) 등 거의 모든 진료과에서 사용되었다. Fentanyl citrate 주사용 제제는 신경외과(34.0)%, 일반외과(25.9%), 정형외과(14.3%), 산부인과(9.6%)의 순으로 사용되었으며 내과에서의 사용량은 33 내과를 전문내과별로 세분하여 연도별 사용양상을 살펴보 면 혈액종양내과에서 내과 전체 사용량의 절반 이상을 차지 하여 가장 많이 사용하였으며 이어서 감염내과, 호흡기내과, 소화기내과의 순서로 나타났다(Fig. 7). 특히 2009년도에는 혈액종양내과가 내과 전체 사용량의 70%를 차지하였는데 이 는 2009년도 암센타 개원이 원인인 것으로 여겨진다. 최근에 는 알레르기내과에서 사용량이 증가하여 2009년의 경우 소 화기내과에 이어서 내과 중에서는 다섯 번째로 마약성 진통 제를 많이 사용하는 것으로 나타났다. 암성 통증의 치료에 사용된 마약성 진통제의 양과 백분율 은 Table 2에 요약되어 있다. 주사용 제제 중에서 암성 통증 에 주로 사용되는 것은 morphine 뿐이며 pethidine, fentanyl, remifentanil 등 그 밖의 약물은 95% 이상이 암성 통증과 관 계없는 다른 목적으로 사용되고 있는 것으로 나타났다. 반면 에 경구용 제제와 경피용 제제의 경우는 codeine 단일제제 및 codeine 함유 복합제제(codeine phosphate 10 mg, ibuprofen 200 mg, acetaminophen 250 mg)를 제외한 모든 약물이 암성 통증에 주로 사용되었음을 알 수 있다. Codeine 단일제제는 기관지확장증과 천식 등 호흡기질환에 약 20%가 사용되었으 며, codeine 함유 복합제제는 각종 진단시 통증 및 기타 통증 Fig. 7. Drug use pattern of narcotic analgesics by divisions in the department of internal medicine
