Innervation of the kidney and two effects of sympathetic stimulation on renal function. Introduction: Metabolism of the human body inevitably produces a variety of unwanted or waste products. This waste product is not simply needed by the body. If it is allowed to accumulate in the body, it may produce harmful effects. These wastes are completely excreted from our body through digestive tracts, respiratory tracts, and by the sweat glands. The principal system that is involved in the excretion of waste is the urinary system. From the blood, the metabolic waste is removed by the kidney. The rest of the urinary system involves in the elimination of urine, storage, and for transport. The kidney plays an important role in controlling the blood pressure and blood volume. Kidney physiology is administrated by certain principles. This includes osmotic pressure, down pressure, and electrochemical gradients. The stages of urine production and the role of the kidney (regulating urine concentration and fluid balance) mainly depend on concepts like osmolarity, tonicity, and osmosis.

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…
