Summary

Introduction: The cough is the more common respiratory symptom in children and adults.

Objective: To present a revision on the neurophysiology and the methods for study of the consequence of the cough, as well as the pharmacotherapy and phonoaudiology therapy of the cough, based on the works published between 2005 and 2010 and indexed in the bases Medline, Lilacs and Library Cochrane under them to keywords “cough” or “anti-cough”.

Synthesis of the data: The consequence of the cough involves activation of receiving multiples becomes vacant in the aerial ways and of neural projections of the nucleus of the solitary treatment for other structures of the central nervous system. Experimental techniques allow studying the consequence of the cough to the cellular and molecular level to develop new anti-cough agents. It does not have evidences of that anti-cough exempt of medical lapsing they have superior effectiveness to the one of placebo for the relief of the cough. The phonoaudiology therapy can benefit patients with refractory chronic cough to the pharmacological treatment, over all when paradoxical movement of the vocal folds coexists.

Final Comments: The boarding to multidiscipline has basic paper in the etiological diagnosis and treatment of the cough. The otolaryngologist must inform the patients on the risks of the anti-cough of free sales in order to prevent adverse poisonings and effect, especially in children.

Resumo

Introdução: A tosse é o sintoma respiratório mais comum em crianças e adultos.

Objetivo: Apresentar uma revisão sobre a neurofisiologia e os métodos para estudo do reflexo da tosse, bem como a farmacoterapia e terapia fonoaudiológica da tosse, baseada nos trabalhos publicados entre 2005 e 2010 e indexados nas bases Medline, Lilacs e Biblioteca Cochrane sob os unitermos “tosse” ou “antitussígenos”.

Síntese dos dados: O reflexo da tosse envolve ativação de múltiplos receptores vagais nas vias aéreas e de projeções neurais do núcleo do trato solitário para outras estruturas do sistema nervoso central. Técnicas experimentais permitem estudar o reflexo da tosse ao nível celular e molecular para desenvolver novos agentes antitussígenos. Não há evidências de que antitussígenos isentos de prescrição médica tenham eficácia superior à do placebo para o alívio da tosse. A terapia fonoaudiológica pode beneficiar pacientes com tosse crônica refratária ao tratamento farmacológico, sobretudo quando coexiste movimento paradoxal das pregas vocais.

Comentários Finais: A abordagem multidisciplinar tem papel fundamental no diagnóstico etiológico e tratamento da tosse. O otorrinolaringologista deve informar os pacientes sobre os riscos dos antitussígenos de venda livre a fim de prevenir intoxicações e efeitos adversos, especialmente em crianças.
