Half-Life Time of Medicine

The half-life of medicinal substances is the period of time required to reduce the concentration of a drug in the blood by 50%. In most cases, this process involves the cleansing of the body by the kidneys and liver, complete with the function of excretion and removal of the substance from the body. Using the calculator below, you can easily calculate the half-life (t1/2) of the drugs used.
