Claims for Patent: 6,479,500

Title: Agents for alleviating side effects
Abstract:The present invention provides an agent for alleviating side effects caused by use of an anti-tumor agent, which contains 5-chloro-6-(2-iminopyrrolidin-1-yl)methyl-2,4(1H,3H)-pyrimidi nedione (1) represented by formula (1): ##STR1## or a pharmaceutically acceptable salt thereof. The 5-chloro-6-(2-iminopyrrolidin-1-yl)methyl-2,4(1H,3H)-pyrimidinedione or a pharmaceutically acceptable salt thereof exhibit an inflammatory-suppressing action in the digestive tract and advantageously alleviate diarrhea and loss of body weight concomitant with administration of a chemical for treating cancer without suppressing the anti-tumor effect. Thus, the compounds of the present invention are of great value as agents for alleviating side effects caused by use of an anti-tumor agent, which enable not only the chemotherapy to be continuedly carried out, but also the body exhaustion to be effectively prevented.
