pubmed-article:2971187 | pubmed:abstractText | RU 41740 is an immunomodulator of organic origin to be used preventively against recurrent respiratory infections in both adults and children. The immunological safety of the drug was first studied on NZB-NZW mice which spontaneously develop a disease resembling lupus erythematosus. The survival rate of these mice and the amounts of protein excreted in the urine were not modified by the compound. Clinically, RU 41740 was well tolerated by the adult mice and their offspring. Studies on immunological safety were also conducted in human adults and children. Compared with pre-treatment values, there were no pathological changes in blood count and differential, erythrocyte sedimentation rate, immunoglobulins E, A, M and G levels, apolipoproteins, haptoglobin, haemolytic complement, antinuclear factors, rheumatic serology and anti-red cell antibodies. In addition, the drug was well tolerated by atopic subjects. | lld:pubmed |
