The creation of the pressure gradient in the lungs causes the movement of the air from the outside to the inside of the lungs. There are variations of pressure inside the lungs which causes the lowering of the atmospheric pressure. The pulmonary ventilation causes the changes of the pressure inside the lungs which obeys the Boyle’s law. A single respiratory cycle consists of the inspiration and expiration process which brings air inside the lungs and moves air out of the lungs.

1. In vivo testing provides valuable insight into a drug’s kinetics. Assessing drug kinetics following multiple different routes of administration provides greater insight than just a single route of administration alone. The following data was collected in 250 g rats following bolus iv, oral (po), and intraperitoneal (ip) administration.Using this data and set of graphs, determine: (a) k, C0, V, and AUC* for the bolus iv data (b) k, ka, B1, and AUC* for the po data (c) k, ka, B1, and AUC* for the ip data (d) relative bioavailability for po vs ip, Fpo/Fip (e) absolute po bioavailability, (f)Fpo absolute ip bioavailability, Fip MAKE SURE ANSWERS HAVE UNITS if appropriate.

2. Drug quantification from plasma is commonly performed by using techniques such as HPLC or LC/MS. However, these methods do have limitations, and investigators may choose to use a radiolabeled analog of a drug instead. Radioligands are molecules that contain radioactive isotopes, commonly 3H or 14C. This technique allows investigators to quantify drug concentration from radiation measurements. The following measurements were made in 250 g rats following oral administration of 18.2 µCi of a 14C-labeled drug of interest: Time (min) Plasma Radiation Levels (µCi/L) 0 0.0 2 9.7 4 19.2 7 25.3 9 37.8 12 39.6 14 45.8 17 48.8 20 52.0 25 56.4 30 59.2 35 60.1 40 61.1 45 62.1 50 62.8 60 63.1 70 62.1 80 60.1 90 57.3 100 55.5 110 53.7 120 52.2 150 48.0 180 45.0 240 39.0 Note that a µCi is a measure of the amount of radioactivity and hence is a measure of the amount of drug present. Given that the oral bioavailability of this drug is known to be essentially 100%, estimate the following from this…
