United States National Library of Medicine.Therapeutic drug monitoring (TDM) is commonly used to help maintain drug levels within the therapeutic window,1,2 the concentration range in which a drug exerts its clinical effect with minimal adverse effects for mac blu ray player codec most patients."From ultrasocial to antisocial: a role for oxytocin in the acute reinforcing effects and long-term adverse consequences of drug use?".If the plasma half-life or terminal half-life( t1/2 -the time it takes for the plasma concentration to fall to 50 of its starting value) is long, doses can be given at relatively long intervals(once per day but if the t1/2 is short(less than about.2) Hammett-Stabler CA, Dasgupta A, eds.Hoever, The Ke and T1/2 are considered constants in pharmacokinetic equations.1,320 mg/Lh 0 displaystyle AUC_0-infty 0 C d t displaystyle int _0infty C,operatorname d t, ss displaystyle AUC_tau,textss t t C d t displaystyle int _tttau C,operatorname d t Clearance The volume of plasma cleared of the drug per unit time.The first phase is the distribution phase.That is, the half-life that results from distribution and/or elimination processes of a drug in a biological organism.
For example, for a drug with two compartment kinetics, this would refer to the second elimination phase(beta).
It is crucial to know a drug's half-life.
1, typically, this refers to the body's cleansing through the function of kidneys and liver in addition to excretion functions to eliminate a substance from the body.
A person who has ingested ethylene glycol can be treated in the same way.

A drug's half-life is the time it takes for a drug to lose half its strength in the body.It also indicates whether accumulation of the drug will occur under a multiple dosage regimen and it is essential to decide on the appropriate dosing interval.For some substances, it is important to think of the human or animal body as being made up of several parts, each with their own affinity for the substance, and each part with a different biological half-life ( physiologically-based pharmacokinetic modelling ).Recent studies also highlight remarkable anxiolytic and prosocial effects of intranasally administered OT in humans, including increased trust, decreased amygdala activation towards fear-inducing stimuli, improved recognition of social cues and increased gaze directed towards the eye regions of others (Kirsch., 2005; Kosfeld.V Google nashol sledujuscuju frazu: ml, in the pharmacokinetic area of study the half-life of a drug usually refers to the biological or terminal half-life.25 Mar, 2015 0 comments.
