A maximum rate of reaction is reached when drug concentration achieves 100% enzyme saturation. Beyond this concentration, clearance will be zero-order.

First order and Zero Order kinetics. First order kinetics occur when a constant proportion of the drug is eliminated per unit time. Rate of elimination is proportional to the amount of drug in the body. The higher the concentration, the greater the amount of drug eliminated per unit time. For every half life that passes the drug concentration is halved.

Both zero and first-order kinetics derive from the same equation. As seen in "Equation No. 1 "Kinetic order elimination equation," where delta [drug] represents the change in plasma concentration of the drug divided by time, "n" represents either first or zero-order elimination with 1 or 0, respectively, and "-Kc" represents a constant.

When phenytoin is given in doses less than 300 mg per day the CYP enzymes which biotransform it are not saturated, and so the elimination of phenytoin follows first-order kinetics. However, when it is given in doses larger than 300 mg per day the CYP enzymes are saturated, causing the elimination to switch to zero-order kinetics.

First order kinetics is a concentration-dependent process (i.e. the higher the concentration, the faster the clearance), whereas zero order elimination rate is independent of concentration. Michaelis-Menten kinetics describes enzymatic reactions where a maximum rate of reaction is reached when drug concentration achieves 100% enzyme saturation.

Definition. First Order Kinetics: First order kinetics refers to chemical reactions whose rate of reaction depends on the molar concentration of one reactant. Zero Order Kinetics: Zero order kinetics refers to chemical reactions whose rate of the reaction does not depend on the reactant concentration.

First-order reactions are very common. We have already encountered two examples of first-order reactions: the hydrolysis of aspirin and the reaction of t-butyl bromide with water to give t-butanol. Another reaction that exhibits apparent first-order kinetics is the hydrolysis of the anticancer drug cisplatin. Cisplatin, the first “inorganic” anticancer drug to be discovered, is unique in its ability to cause complete remission of the relatively rare, but deadly cancers of the ...

6 0.288 0 a) What type of kinetics is observed? Zero order, first order, second order? Why? A plot of the log of the plasma concentration versus time is linear, so it is likely that the elimination is governed by first-order kinetics. b) Is there a plasma half-life for the drug? If so, what is it? Yes, since the kinetics are first-order.

Drugs with this type of kinetics begin as first-order kinetics, but can change to zero order once a certain dose is reached and metabolizing enzymes are saturated. At this point, toxicity can result. When a drug is administered intravenously, which of the following steps does not occur?
