Effect Of Piperine In Patients With Oropharyngeal Dysphagia (FIS 2009_2)

This study has been completed.
Information provided by (Responsible Party):
Pere Clave, Hospital de Mataró Identifier:
First received: June 27, 2011
Last updated: February 27, 2015
Last verified: February 2015
Piperine acts on the oropharyngeal TRPV1, increasing sensory input and the release of substance P. These actions may accelerate the oropharyngeal swallow response, improving the swallowing of dysphagic patients.

Condition Intervention Phase
Deglutition Disorders Drug: Piperine Phase 1 Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Effect of Natural Agonists of TRPV1 in the Treatment of Functional Oropharyngeal Dysphagia in Neurological Diseases and the Elderly: Piperine
