Application Number:	17/314,330
Patent Claims:	1. A method for administering paliperidone palmitate to a patient in need thereof who has been administered a first dose of a first paliperidone palmitate extended-release injectable suspension (first suspension), the method comprising: administering in a deltoid muscle of the patient a re-initiation loading dose of a second paliperidone palmitate extended-release injectable suspension (second suspension) at a time that is more than six months and three weeks after administration of said first dose of the first suspension but less than eight months after administration of said first dose of the first suspension; and administering in a deltoid or gluteal muscle of the patient a maintenance dose of the first suspension at a time that is one month .+-.7 days after administering the re-initiation loading dose of the second suspension; wherein there is no intervening dose of paliperidone palmitate between the first dose of the first suspension and the re-initiation loading dose of the second suspension, and no intervening dose of paliperidone palmitate between the re-initiation loading dose of the second suspension and the maintenance dose of the first suspension; wherein the first suspension is a six-month extended release injectable suspension (PP6M), and the second suspension is a one-month extended release injectable suspension (PP1M). 2. The method of claim 1, wherein the first dose of the first suspension comprises about 1092 mg of paliperidone palmitate; the re-initiation loading dose of the second suspension comprises about 156 mg of paliperidone palmitate; and the maintenance dose of the first suspension comprises about 1092 mg of paliperidone palmitate. 3. The method of claim 1, wherein the first dose of the first suspension comprises about 1560 mg of paliperidone palmitate; the re-initiation loading dose of the second suspension comprises about 234 mg of paliperidone palmitate; and the maintenance dose of the first suspension comprises about 1560 mg of paliperidone palmitate. 4. The method of claim 1, wherein the first dose of the first suspension and the maintenance dose of the first suspension are administered in a gluteal muscle. 5. The method of claim 1, wherein the patient is in need of treatment for psychosis, schizophrenia, schizoaffective disorder, schizophreniform disorder, or bipolar disorder. 6. The method of claim 5, wherein the patient is in need of treatment for schizophrenia. 7. The method of claim 1, wherein the first suspension comprises: about 280 mg/mL to about 350 mg/mL of the paliperidone palmitate; about 8 mg/mL to about 12 mg/mL of a wetting agent; one or more buffering agents; about 65 mg/mL to about 85 mg/mL of a suspending agent; and water q.s. ad 100%. 8. The method of claim 7, wherein the first suspension is from about pH 6.0 to about pH 8.0. 9. The method of claim 7, wherein the one or more buffering agents comprise citric acid monohydrate, sodium dihydrogen phosphate monohydrate, disodium hydrogen phosphate anhydrous, or sodium hydroxide. 10. The method of claim 7, wherein the first suspension comprises: about 312 mg/mL of paliperidone palmitate; about 10 mg/mL of polysorbate 20; and about 75 mg/mL of polyethylene glycol 4000. 11. The method of claim 7, wherein the second suspension comprises: about 140 mg/mL to about 180 mg/ml of the paliperidone palmitate; about 8 mg/mL to about 16 mg/ml of a wetting agent; one or more buffering agents; about 20 mg/mL to about 40 mg/ml of a suspending agent; and water q.s. ad 100%. 12. The method of claim 11, wherein the second suspension is from about pH 6.0 to about pH 8.0. 13. The method of claim 11, wherein the one or more buffering agents comprise citric acid monohydrate, sodium dihydrogen phosphate monohydrate, disodium hydrogen phosphate anhydrous, or sodium hydroxide. 14. The method of claim 11, wherein the second suspension comprises: about 156 mg/mL of paliperidone palmitate; about 12 mg/mL of polysorbate 20; and about 30 mg/mL of polyethylene glycol 4000. 15. The method of claim 2, wherein the patient is in need of treatment for psychosis, schizophrenia, schizoaffective disorder, schizophreniform disorder, or bipolar disorder. 16. The method of claim 15, wherein the patient is in need of treatment for schizophrenia. 17. The method of claim 16, wherein the first dose of the first suspension and the maintenance dose of the first suspension are administered in a gluteal muscle. 18. The method of claim 17, wherein the first suspension comprises about 280 mg/mL to about 350 mg/mL of paliperidone palmitate, and the second suspension comprises about 140 mg/mL to about 180 mg/ml of paliperidone palmitate. 19. The method of claim 17, wherein the first suspension comprises: about 280 mg/mL to about 350 mg/mL of paliperidone palmitate; about 8 mg/mL to about 12 mg/mL of a wetting agent; one or more buffering agents; about 65 mg/mL to about 85 mg/mL of a suspending agent; and water q.s. ad 100%. 20. The method of claim 19, wherein the second suspension comprises: about 140 mg/mL to about 180 mg/ml of paliperidone palmitate; about 8 mg/mL to about 16 mg/ml of a wetting agent; one or more buffering agents; about 20 mg/mL to about 40 mg/ml of a suspending agent; and water q.s. ad 100%. 21. The method of claim 3, wherein the patient is in need of treatment for psychosis, schizophrenia, schizoaffective disorder, schizophreniform disorder, or bipolar disorder. 22. The method of claim 21, wherein the patient is in need of treatment for schizophrenia. 23. The method of claim 22, wherein the first dose of the first suspension and the maintenance dose of the first suspension are administered in a gluteal muscle. 24. The method of claim 23, wherein the first suspension comprises about 280 mg/mL to about 350 mg/mL of paliperidone palmitate, and the second suspension comprises about 140 mg/mL to about 180 mg/ml of paliperidone palmitate. 25. The method of claim 23, wherein the first suspension comprises: about 280 mg/mL to about 350 mg/mL of paliperidone palmitate; about 8 mg/mL to about 12 mg/mL of a wetting agent; one or more buffering agents; about 65 mg/mL to about 85 mg/mL of a suspending agent; and water q.s. ad 100%. 26.
