The Operational Multiple Dosing Half-life A Key to Defining Drug

If a drug is dosed at a frequency equal to the drug's half-life, the patient exposure to the drug at steady state during a dosing interval will be twice the.. The last column in Table II provides comments on the usefulness of each term with respect to predicting drug accumulation upon multiple dosing as will be.

Thus, one might suspect that the generally reported long half-lives are not relevant in achieving therapeutic efficacy for diazepam (we note that the package insert for diazepam tablets makes no mention of half-life). Probably the best example relating to the discrepancy between the terminal half-life and the operational half-life is for the commonly used anxiolytic drug diazepam, although to our knowledge this has not been examined carefully in the literature. If one looks up the diazepam half-life in Goodman and Gilman (43±13 h) ( 1 ), the Drug Information Handbook (20–50 h) ( 2 ) or any other standard reference book, a long half-life is reported.

However, workplace drug testing is now common in general for many U.S. employers to lessen the impact from drug abuse, safety concerns, and low productivity in the workplace. Drug testing is often done when applying for employment, especially for positions that may involve federal transportation, airline industries, railways, hospitals, and other workplaces where public safety is of the utmost importance.

Blood flow to the organs determines how rapidly the volume of distribution is delivered to the organs of elimination. Hepatic efficiency is determined by the metabolic ability of the liver for the specific drug. Almost all drugs move out to the extracellular space and SOME into the intracellular space. Administering a drug to an animal is dissolving a drug in a bag of water. The liver and the kidneys process water (the volume of distribution) to get the drug.

If the frequency of taking a capsule/tablet (say 12 hours) is much shorter than the drug half life (say 24 hours), the capsule/tablet may be eliminated at something like three times the period of the half-life to reduce the average drug level slowly. The residual drug from the other capsules/tablets sustains the background level.
