The adverse response of the drug on the body. C. The effect the body has on the drug. D. The clinical formulation of the drug - CORRECTANSWER C. The effect the body has on the drug. Absorption, distribution, metabolism, excretion The ratio of minimum effective concentration (MEC) to minimum toxic concentration (MTC) of a drug is the: - CORRECTANSWER therapeuti c window half life: - CORRECTANSWER the time it takes for the plasma concentration of the drug to be reduced to half of its original value Drug clearance formula - CORRECTANSWER rate of drug elimination / plasma concentration of the drug

steady state - CORRECTANSWER when the r ate of drug input equals the rate of drug elimination Which of the following actions triggers a rise in membrane or action potential of a cell? A. Opening of the voltage gated sodium ions B. Closure of voltage gated sodium ions C. Opening of calcium ion channel D. Opening of potassium voltage gated channels - CORRECTANSWER A. Opening of the voltage gated sodium ions Before stimulation, a cell has a slightly negative electric charge (compared with ECF). Outside is more positively charged. When stimulus is encount ered, sodium ion channel opens and sodium rushes into the cell, causing depolarization (rise in membrane/action potential) The process by which a drug's activity is altered in order to prepare it for excretion: - CORRECTANSWER biotransformation The amino acid found in dairy products, fish, and eggs is tyrosine. The amino acid from which tyrosine is made is: - CORRECTANSWER phenylalanine.
