But is also equivalent to divided by elimination rate half-life /, = /. Thus, C l t o t = ln 2 ⋅ V d t 1 / 2 {\displaystyle Cl_{tot}={\dfrac {\ln 2\cdot V_{d}}{t_{1/2}}}} . This means, for example, that an increase in total clearance results in a decrease in elimination rate half-life, provided distribution volume is constant.
take (often effectively a noun meaning "prescription"—medical prescription or prescription drug) rep. repetatur: let it be repeated s. signa: write (write on the label) s.a. secundum artem: according to the art (accepted practice or best practice) SC subcutaneous "SC" can be mistaken for "SL," meaning sublingual.

Absorption half-life 1 h, elimination half-life 12 h. Biological half-life ( elimination half-life , pharmacological half-life ) is the time taken for concentration of a biological substance (such as a medication ) to decrease from its maximum concentration ( C max ) to half of C max in the blood plasma .
In this situation it is generally uncommon to talk about half-life in the first place, but sometimes people will describe the decay in terms of its "first half-life", "second half-life", etc., where the first half-life is defined as the time required for decay from the initial value to 50%, the second half-life is from 50% to 25%, and so on.
As often as we go to CVS, we rarely think about what the acronym actually means.
It was proposed to be used instead of AUC in animal-to-human dose translation, as computer simulation shows that it could cope better with half-life and dosing schedule variations than AUC. This is an example of a PK/PD model, which combines pharmacokinetics and pharmacodynamics. [13]
Tadalafil has a half-life of 17.5 hours — it remains active in your body for far longer than other ED medications. A single dose of tadalafil can improve blood flow to your privates and make it ...
A loading dose is most useful for drugs that are eliminated from the body relatively slowly, i.e. have a long systemic half-life. Such drugs need only a low maintenance dose in order to keep the amount of the drug in the body at the appropriate therapeutic level , but this also means that, without an initial higher dose, it would take a long ...
