title: Comparison of compliance between topical aural medications.
abstract: Patients receiving Gentisone HC, Sofradex and Otomize for chronic suppurative otitis media and otitis externa were investigated for compliance of medication. Drops were accurately weighed before and after use so that both the amount used and the expected amount patients should have used could be calculated. The amount used differed statistically from the amount expected for Sofradex (P = 0.0008) but not for Gentisone HC (P = 0.1049) or Otomize (P = 0.7553) when analysed by a Mann-Whitney U-test. There was a trend to overdose with both Sofradex & Gentisone HC. The reason for the differences, we believe, is due to a combination of both differing delivery systems and drop viscosities. Manufacturers need to improve delivery systems so that patients can deliver a reproducible volume of medication each time with ease.
