Accumulating data shows that selective serotonin reuptake inhibitor treatment can also be efficacious in patients with generalized anxiety disorder. This review summarizes the findings of randomized controlled trials of selective serotonin reuptake inhibitor treatment for generalized anxiety disorder, examines the strengths and weaknesses of other therapeutic approaches and considers potential new treatments for patients with this chronic and disabling anxiety disorder

O presente artigo apresenta uma visão atualizada e ampla do tratamento farmacológico do transtorno de ansiedade generalizada (TAG). São revistos os medicamentos com eficácia comprovada em estudos controlados e atualmente disponíveis na clínica (benzodiazepínicos, buspirona, antidepressivos, betabloqueadores, antipsicóticos e extrato de kava-kava). A seguir, baseados nesses dados, propõe-se um algoritmo de tratamento do TAG. São apresentadas as principais linhas de pesquisa de novos fármacos ansiolíticos, descrevendo os principais achados clínicos e pré-clínicos.<br>This article presents an updated and broad perspective of the pharmacological treatment of generalized anxiety disorder (GAD). Medications proven to be efficacious in controlled studies and available in the clinic setting were reviewed (benzodiazepines, buspirone, antidepressives, beta-blocking agents, antipsychotics and kava-kava extract). From this data, an algorithm for GAD treatment is proposed. In addition, the main research lines on new anxiolytic drugs and their stage of clinical or pre-clinical development are presented
