The solution of this differential equation is useful in calculating the concentration after the administration of a single dose of drug via IV bolus injection: = C t is concentration after time t; C 0 is the initial concentration (t=0) K is the elimination rate constant
Additionally, lysine acetylsalicylate shows a faster onset of action when compared to oral aspirin of an equivalent dose. [18] Lysine acetylsalicylate also displays a shorter mean residence time in the body (0.37 hours) as well as a shorter elimination half-life (17 minutes) when administered intravenously, which could indicate that it displays ...
Therefore, the dose required to give a certain plasma concentration can be determined if the V D for that drug is known. The V D is not a physiological value; it is more a reflection of how a drug will distribute throughout the body depending on several physicochemical properties, e.g. solubility, charge, size, etc.
For years, doctors recommended that older adults at a higher risk for heart attack or stroke take a low-dose aspirin once a day to lower their risk.
In pharmacokinetics, a loading dose is an initial higher dose of a drug that may be given at the beginning of a course of treatment before dropping down to a lower maintenance dose. [1] A loading dose is most useful for drugs that are eliminated from the body relatively slowly, i.e. have a long systemic half-life.
For many drugs, severe toxicities in humans occur at sublethal doses, which limit their maximum dose. A higher safety-based therapeutic index is preferable instead of a lower one; an individual would have to take a much higher dose of a drug to reach the lethal threshold than the dose taken to induce the therapeutic effect of the drug.
Absorption is the journey of a drug travelling from the site of administration to the site of action. [1] [2]The drug travels by some route of administration (oral, topical-dermal, etc.) in a chosen dosage form (e.g., tablets, capsules, or in solution). [3]
However, more recent trials were not able to replicate similar outcomes using low dose aspirin in low body weight (<70 kg) in specific subset of population studied i.e. elderly and diabetic population, and more evidence is required to study the effect of high dose aspirin in high body weight (≥70 kg).
