목적: Capsaicin is the active substance extracted from chili. It has been used in the treatment of non-infectious non-allergic rhinitis (NINAR) since the beginning of the 9th decade. Its merituos effects have been revealed in neurogenic rhinitis. Its usefulness in nasal polyposis is still a matter of debate. 방법:a review of the literature is performed on capsaicin intranasal products. A new line of produscts based on capsaicin is being presented and its effects are being discussed. 결과:intranasal capsaicin reveals the symptomatology (rhinoreea, sneezing & nasal obstruction) in NINAR but has little effect on the dimensions of polyps in nasal polyposis. Its use may be recommended after endoscopic polipectomies to prevent recidive. The compliance has been good among the subjects of the study. Capsaicin decreases nasal hyperreactivity of the nose in all groups of patients and is efficient in gustatory rhinitis. 결론:furher studies are being necessary in order to assess the adequate efficacity and safety of the drug.
