Pakonsekan, mwatye lavi senpleman refere a peryòd de tan ki nesesè pou konsantrasyon nan dwòg la ap redwi pa 1/2 nan kantite lajan yo bay yo. Se konsa, nan ka ester acetate a, si ou enjekte 100 miligram (mgs) nan acetate Lè sa a, apre 3 jou (longè tan nan mwatye lavi) ou pral gen 50mgs toujou prezan nan kò a; apre 3 jou plis sèlman 25mg, ak sou sa.

Hence, half life simply refers to the period of time needed for the concentration of the drug to be reduced by 1/2 of the given amount. Thus, in the case of the acetate ester, if you inject 100 milligrams (mgs) of acetate then after 3 days (length of time of half life) you will have 50mgs still present in the body; then after 3 more days only 25mg, and so on.
