| Patent Claims: |
1. A free drug particulate form of a compound having a formula ##STR3##
or pharmaceutically acceptable salts and solvates thereof, comprising particles of the compound wherein at least 90% of the particles have a particle size of less than about 40 microns. 2. The free drug particulate form of claim 1 wherein at least 90% of the particles have a particle size of less than about 25 microns. 3. The free drug particulate form of claim 1 wherein at least 90% of the particles have a particle size of less than about 15 microns. 4. The free drug particulate form of claim 1 wherein at least 90% of the particles have a particle size of less than about 10 microns. 5. A pharmaceutical solid composition comprising the free drug particulate form as in any one of claims 1-4 and one or more pharmaceutically-acceptable carriers, diluents, or excipients. 6. A method of treating sexual dysfunction in a patient in need thereof, which comprises administering to the patient a therapeutically effective amount of a solid composition comprising the free drug particulate form as in any one of claims 1-4 and one or more pharmaceutically-acceptable carriers, diluents, or excipients. 7.
