Effects of mouth wash (mouth rinsing and gargling) on the removal of drug residues in both mouth and pharynx after the use of pressurized aerosol metered-dose inhaler (MDI) were studied. The concentration of beclomethasone dipropionate (BM) in mouth wash after a splay of Becotide^[○!R] inheler was measured by the method using HPLC. The total amount of the removed BM was measured by a sum of the concentrations of BM in 4 or 5 times of mouth washes in the following 4 kinds of methods. In method 1,mouth wash was done with 5 times of water change after a splay of MDI on wetted mouth. In method 2,mouth wash was done with 5times of change water on dried mouth. In method 3,mouth wash was done with 4 times of change saliva on wetted mouth. In these methods, the actual inhalation of BM was not done. In method 4,mouth wash was done with 5 times of change water after a splay and a inhalation on wetted mouth. The mouth wash procedures removed totally 47.9%, 51.1%, 31.3%, and 33.3% of a splayed amount of BM in each method, respectively. It was required for the removal of 90% of the totally recovered BM to do one time of mouth wash in method 1,two times in method 2,three times in method 3,and two times in method 4,respectively. These data suggest that the mouth wash procedure is shown to have prophylactic benefit for candidiasis induced by steroid delivered by MDI.
