N. Gaddipati et al., DEVELOPMENT OF A HIGH-DOSE TECHNETIUM TC99M LABELED SULFUR COLLOID METERED DOSE INHALATION AEROSOL, Drug development and industrial pharmacy, 19(10), 1993, pp. 1159-1168
Radiolabeled Technetium sulfur colloid metered dose inhalation aerosol
(MDI) suitable to evaluate pulmonary deposition from inhalation devic
es has been developed by using a lyophilization process to prepare the
radiolabeled material for aerosolization. The reproducibility of the
manufacturing process was demonstrated by characterizing the aerosol p
erformance with respect to dose delivery, particle size, and valve del
ivery.
