| Popis: | 1 It is commonplace for drugs to vary by only minor chemical differences. This is particularly so for those seven benzodiazepines discussed in this paper which are related both as precursors and as metabolites. However, minor chemical differences may cause major differences in physicochemical and pharmacodynamic properties. 2 Although the physicochemical differences are difficult to relate to effect, the influence of structure on absorption, distribution and elimination is of considerable importance in governing duration of effect, as shown by studies in monkeys and in man. This in turn dictates the suitability of a particular drug as a day or night sedative, as an anticonvulsant, or as an anxiolytic. 3 Structure affects the relative potency of the compounds as anticonvulsants, anxiolytics or sedatives so that judicious choice of a particular compound for a particular patient and condition will lead to improved therapy. It is fallacious to consider all benzodiazepines as similar. |
