The onset mechanism of nocturia in the elderly and the possibility of ramelteon

: Nocturia causes sleep disorder and affects not only the fall of QOL but also the increase of falling and bone fracture risk, and life convalescence. Therefore, among the elderly who are particularly likely to fall down, it is necessary to pay attention to them to prevent them from falling down, in addition to their treatment for nocturia. On the other hand, it is also necessary to be careful for insomnia which the prevalence rate rises by aging, because of their sleep getting divided by nocturia. In the examination at our hospital, by the dosage of ramelteon to the insomniac patients complicated with nocturia, the increase of night bladder capacity and the decrease in number of urination times during night were accepted with improvement in insomnia. In addition, adverse event was not accepted. From now on, we regard ramelteon as one of the new treatment choices for insomniac patients complicated with nocturia.
