Elimination Kinetics: Types, Half-Life and Bioavailability
WebHalf-Life. The drug half-life ( t1/2) is the time required for a drug concentration to decrease by 50%. Half-life is a first-order kinetic process because the same proportion, 50%, of … WebHalf-life (T ½) may be defined as the time taken for the concentration of a compound/toxicant in plasma to decline by ½ or 50% of its initial value (or it may be defined as the time required for the body to eliminate half of the chemical). This value is determined during the elimination phase of a chemical; therefore, it is called elimination ... einstein hospital plymouth meeting pa
