In brief: About 24 hours

Half of the drug in codral that stimulates the heart beat should be metabolized by 5-8 hours, so if the rapid heart beat is caused by that, expect improvement by 10-16 hours.
Other factors that cause a rapid heart beat are dehydration and fever, so push the fluids and take fever meds like acetaminophen or ibuprofen. See your doctor if no relief, as it may indicate a more serious infection.
