Application Number:	US17/822,872
Patent Claims:	1. A oral pharmaceutical composition, comprising: a plurality of xanomeline beads comprising xanomeline or a salt thereof; and a plurality of trospium beads comprising trospium chloride; the composition having a dosage strength chosen from: 50 mg xanomeline free base and 20 mg trospium chloride, 100 mg xanomeline free base and 20 mg trospium chloride, and 125 mg xanomeline free base and 30 mg trospium chloride. 2. The oral pharmaceutical composition of claim 1, wherein the composition: has a dissolution rate such that at least 80% of the xanomeline or a salt thereof and the trospium chloride is released within 20 minutes in pH 6.8 buffer solution; or has a dissolution rate such that more than about 95% of xanomeline or a salt thereof and the trospium chloride is released within about the first 45 minutes following entry of the composition into an aqueous solution. 3. The oral pharmaceutical composition of claim 1, wherein the composition, when administered to a patient in need thereof, is sufficient to provide an in-vivo plasma profile comprising a median Tmax for xanomeline of 2 hours and a median Tmax for trospium of 1 hour. 4. The oral pharmaceutical composition of claim 1, wherein the oral pharmaceutical composition has a dosage strength of 50 mg xanomeline free base and 20 mg trospium chloride. 5. The oral pharmaceutical composition of claim 1, wherein the oral pharmaceutical composition has a dosage strength of 100 mg xanomeline free base and 20 mg trospium chloride. 6. The oral pharmaceutical composition of claim 1, wherein the oral pharmaceutical composition has a dosage strength of 125 mg xanomeline free base and 30 mg trospium chloride. 7. The oral pharmaceutical composition of claim 1, wherein the composition: has total impurities no greater than 5% after 12 months at 25° C./60% RH; or has total impurities no greater than 5% after 12 months at 30° C./65% RH; or has total impurities no greater than 5% after 12 months at 40° C./75% RH; or has total impurities no greater than 5% after 6 months. 8. The oral pharmaceutical composition of claim 1, wherein the composition comprises less than 0.5 wt. % of Impurity A after the composition is stored for 3 months at 40° C. and 75% relative humidity. 9. The oral pharmaceutical composition of claim 1 further comprising an antioxidant. 10. The oral pharmaceutical composition of claim 9, wherein the antioxidant is ascorbic acid. 11. The oral pharmaceutical composition of claim 1, wherein the xanomeline salt is xanomeline tartrate. 12. A method for treating schizophrenia in a patient in need thereof comprising: administering to the patient the composition of claim 1. 13. The method of claim 12, wherein said administering comprises: administering a first oral pharmaceutical composition having a dosage strength of 50 mg xanomeline free base and 20 mg trospium chloride for a first period; administering a second oral pharmaceutical composition having a dosage strength of 100 mg xanomeline free base and 20 mg trospium chloride for a second period; and administering a third oral pharmaceutical composition having a dosage strength of 125 mg xanomeline free base and 30 mg trospium chloride for a third period. 14. The method of claim 12, wherein the patient does not have a history of or high risk of urinary retention, gastric retention, or narrow-angle glaucoma.
