Application Number:	14/971,532
Patent Claims:	1. A method of treating Parkinson's disease in a subject in need thereof, the method comprising: (i) providing a pharmaceutical composition in unit dosage form that is a film having a first portion comprising apomorphine particles comprising acid addition salt of apomorphine and a second portion comprising a pH neutralizing agent, wherein the film comprises the acid addition salt of apomorphine in an amount effective to treat Parkinson's disease; and (ii) administering the film by placing the film sublingually in the mouth of the subject and contacting sublingual mucosal tissue with the film. 2. The method of claim 1, wherein the acid addition salt of apomorphine is apomorphine hydrochloride. 3. The method of claim 1, wherein the film further comprises an antioxidant. 4. The method of claim 1, wherein the film further comprises a permeation enhancer. 5. The method of claim 1, wherein the film further comprises glycerol monostearate. 6. The method of claim 1, wherein the first portion comprises apomorphine particles having an effective particle size of from 1 .mu.m to 10 .mu.m. 7. The method of claim 1, wherein the film comprises a polysaccharide. 8. The method of claim 1, wherein the film comprises from 2 to 40 mg of an acid addition salt of apomorphine. 9. The method of claim 8, wherein the film comprises 12.+-.3 mg of an acid addition salt of apomorphine. 10. The method of claim 8, wherein the film comprises 22.+-.4 mg of an acid addition salt of apomorphine. 11. The method of claim 8, wherein the film comprises 30.+-.5 mg of an acid addition salt of apomorphine. 12. The method of claim 8, wherein the film comprises 35.+-.5 mg of an acid addition salt of apomorphine. 13. The method of claim 1, wherein the pH neutralizing agent is an organic base. 14. The method of claim 1, wherein following sublingual administration the film produces an average circulating apomorphine plasma concentration of at least 3 ng/mL within 20 minutes. 15. The method of claim 1, wherein the film comprises a mucoadhesive polymer. 16. The method of claim 8, wherein the film comprises 15.+-.3 mg of an acid addition salt of apomorphine. 17. The method of claim 1, wherein said first portion is a first layer and said second portion is a second layer. 18. The method of claim 1, wherein said unit dosage form is a non-effervescent unit dosage form. 19. The method of claim 1, wherein the film comprises 12 to 30 mg of an acid addition salt of apomorphine. 20. The method of claim 19, wherein said acid addition salt of apomorphine is apomorphine hydrochloride. 21. The method of claim 17, wherein the film comprises 12 to 30 mg of an acid addition salt of apomorphine. 22. The method of claim 21, wherein said acid addition salt of apomorphine is apomorphine hydrochloride.
