ONSET PREVENTIVE AND THERAPEUTIC AGENT FOR VERRUCA CONSISTING MAINLY OF 3-OXYGERMYLPROPIONIC ACID COMPOUND

PURPOSE:To obtain an onset preventive and therapeutic agent for verruca esp. due to the immune system, consisting mainly of a 3-oxygermylpropionic acid eight-member-based polymer having specific three-dimensional structure. CONSTITUTION:This onset preventive and therapeutic agent for verruca consists mainly of a 3-oxygermylpropionic acid eight-member-based polymer expressed by a three-dimensional structure of the formula {R is CH2CH2C00H; (m) is the weight-average polymerization degree reduced from the weight-average molecular weight of propagermanium propyl ester, being 137 + or -84 [an average of 137 + or - standard deviation (3sigma)]}. The minimum constituent of the polymer is (O1/2)3GeCH2CH2COOH, its experimental formula being C6H10Ge2O7. It is preferable that this medicinal agent be used as an activated composition prepared so as to contain 0.005-50wt.% of an activated and stabilized carrier (e.g. lactose, sucrose, albumin) based on 0.005-5wt.% of the main ingredient.
