WebDrug A has a half-life of 2 hours. Draw a graph that shows the expected changes in plasma concentration of that drug as a function of time after the dose. Now draw a second line on the same graph for a 10 mg single dose. Next draw a third line showing any changes if drug A's half-life is increased to 4 hours, single 5 mg dose. WebThis probability amounts to 50% for one half-life. In an interval twice as long (2 T) the nucleus survives only with a 25% probability (half of 50%), in an interval of three half-life periods (3 T) only with 12.5% (half of 25%), and so on. You can't, however, predict the time at which a given atomic nucleus will decay. chipper credit card
