The purified toxin of the Brazilian scorpion venom (TsTX) enhances the pharmacological actions of directly and indirectly acting substances on several preparations. The enhancing action of TsTX is more pronounced for the indirectly acting drugs, which is highly suggestive of a prejunctional site of action. Secondarily, TsTX does also produce an unspecific increase of sensitivity at the level of the pharmacological receptor itself. The mechanism by which these changes are brought about remains to be determined.
巴西蝎子毒液的纯化毒素（TsTX）可增强直接和间接作用物质对多种制剂的药理作用。TsTX对间接作用药物的增强作用更为显著，这强烈提示其作用位点在神经节前。其次，TsTX确实也会在药理受体自身水平非特异性地增加敏感性。这些变化产生的机制仍有待确定。
