Delivery of beta-blockers through an inhalation route
First Claim
1. A condensation aerosol for delivery of a drug selected from the group consisting of atenolol, pindolol, esmolol, propranolol, and metoprololwherein the condensation aerosol is formed by heating a thin layer containing the drug, on a solid support, to produce a vapor of the drug, and condensing the vapor to form a condensation aerosol,characterized by less than 10% drug degradation products by weight, andan MMAD of less than 5 microns.

Abstract
The present invention relates to aerosols containing of atenolol, pindolol, esmolol, propranolol, or metoprolol that are used in inhalation therapy. In a method aspect of the present invention, of atenolol, pindolol, esmolol, propranolol, or metoprolol is administered to a patient through an inhalation route. The method comprises: a) heating a thin layer of atenolol, pindolol, esmolol, propranolol, or metoprolol, on a solid support to form a vapor; and, b) passing air through the heated vapor to produce aerosol particles having less than 5% drug degradation products. In a kit aspect of the present invention, a kit for delivering of atenolol, pindolol, esmolol, propranolol, or metoprolol through an inhalation route is provided which comprises: a) a thin coating of an atenolol, pindolol, esmolol, propranolol, or metoprolol composition and b) a device for dispensing said thin coating as a condensation aerosol.
