The role played by serendipity in the origin of modern psychopharmacology has proven to be controversial in scientific literature.In its original meaning(Walpole),serendipity refers to discoveries made through a combination of accidents and sagacity.We have implemented an operational definition of serendipity based on finding something unexpected or unintended,regardless of the systematic process that led to the accidental observation,and we have established four different patterns of serendipitous attributability.In this paper,we have analyzed the role of serendipity in the discovery and development of classical antidepressant drugs,tricyclic antidepressants and monoamine oxidase inhibitors as well as heterocyclic,“atypical”or“second generation”antidepressants.The discovery of the antidepressant properties of imipramine and iproniazid,the prototypes of tricyclic antidepressants and monoamine oxidase inhibitors,respectively,fits the mixed type II pattern;initial serendipitous discoveries(imipramine was an antipsychotic and iproniazid was an antituberculosis agent)led secondarily to non-serendipitous discoveries.But the other components of these two families of drugs were developed specifically as antidepressants,modifying the chemical structure of the series leaders,thereby allowing all of them to be included in the type IV pattern,characterized by the complete absence of serendipity.Among the heterocyclic drugs,mianserin(originally developed as an antihistamine)also falls into the type II pattern. 展开更多
