株式会社NRLファーマ製造、株式会社日本健康増進研究会販売のラクトフェリン腸溶製剤(純ラクトフェリンとして1錠に86mgを含有)を本発明の頻尿改善剤を含む医薬組成物として使用した。
ラットを実験動物として用い、酢酸惹起膀胱炎の病態モデルを作成した。この病態モデルは膀胱炎による過敏性の排尿反射亢進により頻尿症状を呈するので、尿路感染症による膀胱炎で惹起される頻尿のモデルである。このラットにおける排尿回数を指標として、経口投与ラクトフェリンの頻尿改善効果を検討した。
排尿困難を訴えた前立腺肥大症患者3名(KA(71歳)、HS(62歳)、GK(47歳))および前立腺がん患者(SM(81歳))を被験者として、ラクトフェリンの頻尿治療効果を検討した。SMは高齢のため手術を拒否し、薬物による治療を受けていた患者である。
排尿量(mL)÷排尿時間(秒)=平均尿流率
