    In research studies on human topics, a recovery of 19% and 34% of allantoin in the urine was observed however just in two individuals and just after the administration of huge dosages of allantoin. After intravenous administration, healing in the urine was practically quantitative with doses of 75 to 600 mgm in the human design. After 240 mgm, excretion continued for 72 hours in human topics and the outcomes were comparable in regards to subcutaneous injection. [4]
