  • Patent number: 11369760
    Abstract: The invention is directed to an inhalation atomizer comprising a counter and a blocking function. Counter rotates each time the atomizer is actuated. The blocking function includes a first protrusion on the counter and a second protrusion on a lower unit of the atomizer. Once the predetermined number of actuations has been achieved, the first protrusion encounters the second protrusion and prevents further rotation of the counter so that the atomizer is blocked from further use.

  • Patent number: 11304901
    Abstract: The present invention is directed to a liposomal formulation having a lipid ingredient encapsulating fluticasone furoate, and a method for preparing the liposomal formulation. The liposome formulation comprises a lipid and a sterol. The method of preparing the liposomes comprises the steps of (1) mixing fluticasone furoate with lipid ingredients comprising a lipid and a sterol, (2) injecting the mixture into normal saline solution, and (3) ultrafiltering and concentrating the resulting solution. This preparation method can produce a liposome formulation having desirable properties and compositions, for example, the ratio of the lipid ingredient, the drug to lipid ratio, and the pH value, which is suitable for nebulization inhalation.
