First order elimination graph

WebSince equation 8.13 has only one exponent, the first-order process is also called as monoexponential rate process. Thus, a first-order process is characterized by … WebAn example is the elimination of alcohol. Drugs that show this type of elimination will show accumula-tion of plasma levels of the drug and hence nonlinear pharmacokinetics. First-order reaction If the amount of drug A is decreasing at a rate that is proportional to A, the amount of drug A remaining in the body, then the rate of elimination

WebJan 8, 2024 · First order elimination means simply that the drug is eliminated from the body faster if the plasma concentration is high than if the plasma concentration is low. Most drugs follow this pattern. … WebGraph of first-order kinetics showing linear relationship between rate of reaction and concentration of drug (equation 8.10). Rearrangement of equation 8.10 yields: dC/C = -Kdt (8.11) Integration of equation 8.11 gives: ln C = ln C0 – Kt (8.12) Equation 8.12 can also be written in exponential form as: C = C0 e- Kt (8.13) WebMay 13, 2024 · Note that, at early time-points (just after the infusion starts), the elimination term in the mass balance is small compared with the absorption term, since elimination follows first-order kinetics and the amount of drug in the body/compartment is small. sunny with cloud clip art

WebClearance reflects the elimination of the drug from the body. This drug elimination generally results from liver metabolism and/or excretion by the kidneys. In order to be eliminated, a drug must be presented to the organs of elimination by the plasma flow. The higher the drug concentration, the more drug is presented to the organs and thus can ... WebFor a first-order drug, the rate of elimination is described as: v = k el [A] ... The post-absorption phase of the graph of log C t vs. t has a slope of 2k e /2.303, and as in the case of a one-compartment model with an intravenous dose, k e can be determined from its terminal slope (Figure 6.6).
