    • The invention provides the use of a photosensitiser which is 5- aminolevulinic acid (5-ALA) or a derivative (e.g. an ester) of 5-ALA, or a pharmaceutically acceptable salt thereof, in the manufacture of a composition for use in methods of photodynamic therapy (PDT) on an animal, wherein said PDT comprises: (a) administering to said animal a composition comprising said photosensitiser; and (b) photoactivating said photosensitiser, and wherein side-effects (e.g. pain and/or erythema) of said PDT are prevented or reduced by use of one or more of (i)-(iv): (i) said composition comprises said photosensitiser in a concentration of less than 10 % wt (e.g. 0.5 to 8 %wt), (ii) said composition is administered for less than 2 hours (e.g. 30 minutes to 90 minutes) prior to said photoactivation, (iii) said photoactivation is carried out with a light source having a fluence rate of less than 50 mW/cm 2 (e.g. 5 to 40 mW/cm 2 ), (iv) said photoactivation is carried out with sunlight. Preferably, side-effects of PDT are prevented or reduced by using (iii) or (iv) in combination with (i) and/or (ii).
    • 本发明提供了5-氨基乙酰丙酸(5-ALA)或5-ALA衍生物(例如酯)或其药学上可接受的盐的光敏剂在制备用于 光动力疗法(PDT),其中所述PDT包括:(a)向所述动物施用包含所述光敏剂的组合物; 和(b)光活化所述光敏剂,并且其中通过使用(i) - (iv)中的一种或多种来防止或减少所述PDT的副作用(例如疼痛和/或红斑):(i)所述组合物包含 浓度小于10%wt(例如0.5至8%wt)的光敏剂,(ii)所述组合物在所述光活化前施用少于2小时(例如30分钟至90分钟),(iii)所述光活化是 用光通量小于50mW / cm 2(例如5〜40mW / cm 2)的光源进行,(iv)进行所述的光活化 用阳光照射。 优选地,通过使用(iii)或(iv)与(i)和/或(ii)组合来防止或减少PDT的副作用。
