Antipsychotic drugs, like all psychotropic drugs, are medications that act on the nervous system and help compensate for the imbalances that cause symptoms. There are several categories, among the most representative we find first-generation (or typical) and second-generation (or atypical) antipsychotics. First-generation antipsychotics appeared first and although they are currently less used, the psychiatrist will assess which is the best treatment in each case. Some of the names in this category are haloperidol or chlorpromazine. Second-generation antipsychotics are those that are administered in most cases currently. They mostly produce a lower number of adverse effects, although it should be noted that each person is different. Some of these drugs are aripiprazole, quetiapine or risperidone, among others.
