Official title
The Role of Age on the Human Cough Reflex
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
In 2004, the investigators initiated a human Capsaicin inhalation experiment under an Investigational New Drug (IND) protocol approved by the FDA (IND 69,642) and the subject safety procedures instituted and approved by the Institutional Review Board (IRB). As part of the study protocol, inhaled Capsaicin solutions were analyzed using high performance liquid chromatography (HPLC). The investigation employed safety procedures while conducting the human inhalation investigations. In addition, during our investigations we observed discrepancies between the predicted Capsaicin concentrations mixed by a registered pharmacist and the actual capsaicin concentrations determined by HPLC. The stability of Capsaicin solutions stored over a seven month period and refrigerated at 4degrees C and protected against ultraviolet light were examined.
