Its a simple precision of which is PREDOMINDANT. All benzo have full agonistic (covers all the receptor) properties exept like flurazepam(who skips one or more subunits). so their sub class is direcly link to the receptor subunits of the GABAa receptor to which they are linking in the most abundantly. So some have more affinity for the one that is goin to put you to sleep, we call then hypnotics. some more muscle relaxing properties and others... Overal they produce the group of effect but in different intensity. Temazepam is classed as an hypnotic but it doesnt destroy its ability to combat anxiety it simply increase daily drowsiness during medication.
