Regulação e modulação da secreção gástrica
Palabras clave:
acido gastrico, acido cloridrico, preparações farmaceuticas, ulcera pepticaResumen
O aumento da secreção de ácido clorídrico, assim como alterações da integridade da mucosa e dos fatores de citoproteção gástrica podem contribuir para a patogênese multi fatorial da úlcera péptica. Atualmente, o tratamento desta doença é geralmente baseado na inibição da secreção ácida gástrica por bloqueadores do receptor H2 da histamina ou por inibição da bomba protônica ou, ainda, pelo uso de antimuscarínicos. O uso de medicamentos citoprotetores ficou restrito à carbenoxolona e ao misoprostol, que possuem diversas contra-indicações. Portanto, a pesquisa de agentes citoprotetores pode dar origem a drogas coadjuvantes ou mesmo a alternativas para o tratamento com anti-secretores.
