- A certain chemotherapy drug C with a molar mass of 275. g/mol is administered intravenously, and has a half-life in the body of 40. min. The maximum safe concentration of C is 400. μM. Suppose a patient has a mass of 90.0 kg and a total blood volume of 4.50 L. Calculate the maximum rate at which the drug can be given to this patient. Be sure your answer has 2 significant digits. minLisinopril is an ACE inhibitor derived from the venom of a Brazilian pit viper frequently used in the treatment of hypertension. Because of Lisinopril's relatively long half life of 12 hours, patients need to take a dose just once per day. A patient takes his first dose, 20 mg, at 6 pm on Saturday. a) How many hours does it take for the amount of Lisinopril in the patient's body to decrease to 16 mg? Round to two decimal places. b) How many milligrams remain in the patient's body right before he takes his next 20 mg at 6 pm on Sunday? Round to two decimal placesA certain drug has a half-life in the body of 2.5 h. Suppose a patient takes one 200. mg pill at 6:00PM and another identical pill 90 min later.
