Terminal plasma half-life is the time required to divide the plasma concentration by two after reaching pseudo-equilibrium, and not the time required to eliminate half the administered dose. When the process of absorption is not a limiting factor, half-life is a hybrid parameter controlled by plasma clearance and extent of distribution. In contrast, when the process of absorption is a limiting factor, the terminal half-life reflects rate and extent of absorption and not the elimination process (flip-flop pharmacokinetics). The terminal half-life is especially relevant to multiple dosing regimens, because it controls the degree of drug accumulation, concentration fluctuations and the time taken to reach equilibrium.

Terminal half-life is the time it takes for the concentration of a drug in the body to decrease by half during the elimination phase, after reaching steady state. It is used to estimate how long a drug will stay in the body once the dosing is stopped. Terminal half-life is influenced by factors such as drug metabolism and elimination rate.

Compared to the length of time for the first half-life of a sample of a radioactive isotope the length of time for the second half-life is?
The length of time for the second half-life is the same as the first half-life. Each half-life represents the time it takes for half of the radioactive atoms in a sample to decay. This process continues exponentially with each subsequent half-life.
Who describes an isotopes half life?
Half-life is described in time units.
When was Planet Half-Life created?
Planet Half-Life was created in 1999.
What is the half life morphine sulfate er?
It's terminal elimination half-life after intravenous administration is normally 2 to 4 hours. In some studies involving longer periods of plasma sampling, a longer terminal half-life of about 15 hours was reported.

How do you import half life 1 weapons into half life 2?
Buy Half Life: Source Or Buy Garrysmod a Half-Life 2 Modification and get the addon "Half-Life Rennaisance" Link to Half Life Rennaisance: http://www.garrysmod.org/downloads/?a=view&id=57033 Enjoy!
Can half-life source be used for half-life mods?
No. Half-Life: Source runs on the Source engine. The original Half-Life doesn't. You cannot use mods made for the original Half-Life on Half-Life: Source because they run on different engines and it won't work.
