| Measure | Time frame |
|---|---|
| Main Objective: To study and compare the effect of throat spray Lidocaine and nebulised Lidocaine on the number of cough counts* in 24 hours. *patients will wear a cough recorder device for a 24 hour period. The recordings will then be analysed to reveal how many times the patient coughed.;Secondary Objective: 1. To study the effect of throat spray Lidocaine on the perception* of the urge to cough; 2. Compare the effect of throat spray Lidocaine with matching placebo on cough; 3. Compare the effect of nebulised Lidocaine with matching placebo on cough. *perception of the urge to cough is recorded using short a questionnaire.;Primary end point(s): - Objective cough counts over 10hr post dose - Change in urge to cough and visual analogue score;Main Objective: To study and compare the effect of throat spray Lidocaine and nebulised Lidocaine on the number of cough counts* in 24 hours. *patients will wear a cough recorder device for a 24 hour period.
