The toxicity of daily inhaled amphotericin B.

Inhaled amphotericin was administered to 29 patients with prolonged neutropenia and toxicity was analyzed. Treatment consisted of 30 mg of amphotericin B administered by nebulizer once daily via either a hand-held nebulizer or face mask. The mean duration of treatment was 16 days. Toxicity was minimal and patient had significant toxic reaction to the inhaled medication. This study documents that nebulized amphotericin B has less than 10% incidence of severe toxicity with 95% confidence level. Guidelines for future trials and use are suggested.
