Can short acting benzodiazepines like triazolam and midazolam, if used for long time, cause withdrawal symptoms? Lets say both drugs have t1/2 of 2 hours, what means you will never achieve steady state concentration using it even every day, and you are "withdrawing" the drug every day, as the concentration of it drops almost to zero in several hours. Dont it mean very short acting benzos are safer in long term perspective?
