보툴리눔 독소는 여러 영역에서 치료적 목적으로 사용되어 왔으며, 그 사용량과 적용범위가 점차 커지는 추세이다. 보툴리눔 독소가 강력한 독성 물질임에도 불구하고, 그 효과가 6개월이면 사라지는 가역적 치료방법이라는 인식이 강해서, 부작용이나 사용시 주의사항을 중요하게 생각하지 않는 경향이 있었다. 하지만 미국에서 부작용으로 사망하는 사례가 발생하여, 사용시 사망에 대한 주의사항이 추가되었다. 이에 본 종설은 보툴리눔 독소가 인체 내에서 대사되는 과정과, 발생 가능한 부작용, 사용시 유의사항, 사망 부작용 사례 등에 대해 지금까지 보고된 문헌들을 토대로 자세히 검토하고자 한다.
Botulinum toxin (BoNT) has been used for a wide spectrum of therapeutic and cosmetic indications, and the range of indications is continually increased. Though BoNT is a powerful poison, the fact that not only the effect but also the adverse effect of it fader about 6 months after injection makes clinicians to neglect its dangerous property in clinical application. But Many reports about the adverse effects including death of BoNT injection have been reported, the FDA edited in additional warnings about hospitalizations and deaths. In this study, we intended to look through the metabolic process in human body, possible adverse effect, matters to be attended in application, and cases reports about deaths of BoNT by reviewing the previous studies.
