Patent Claims: 1. A method of treating a disease selected from the group consisting of affective disorders, depression, major depressive disorder, anxiety, general anxiety disorder, social anxiety disorder, obsessive compulsive disorder, panic disorder, and panic attacks, the method comprising administering a therapeutically effective amount of a pharmaceutically acceptable salt of Compound I to a patient in need thereof, wherein the salt of Compound I is crystalline 1-[2-(2,4-dimethylphenylsulfanyl)-phenyl]piperazine hydrobromide salt characterized by XRPD reflections at 6.89, 9.73, 13.78 and 14.64+/-0.10.degree. 2.theta..

2. The method of claim 1, wherein the hydrobromide salt is characterized by an XRPD as shown in FIG. 3.

3. The method of claim 1, wherein the hydrobromide salt has a particle size distribution corresponding to: D98%: 650-680 .mu.m; D50%: 230-250 .mu.m; and D5%: 40-60 .mu.m; D98%: 370-390 .mu.m; d50%: 100-120 .mu.m; and D5%: 5-15 .mu.m; D98%: 100-125 .mu.m; D50%: 15-25 .mu.m; and D5%: 1-3 .mu.m; or D98%: 50-70 .mu.m; D50%: 3-7 .mu.m; and D5%: 0.5-2 .mu.m.

4. The method of claim 1, wherein the disease is major depressive disorder.

5. A method of treating a disease selected from the group consisting of affective disorders, depression, major depressive disorder, anxiety, general anxiety disorder, social anxiety disorder, obsessive compulsive disorder, panic disorder, and panic attacks, the method comprising administering a therapeutically effective amount of Compound I or a pharmaceutically acceptable salt thereof to a patient in need thereof, wherein Compound I is 1-[2-(2,4-dimethylphenylsulfanyl)-phenyl]piperazine and Compound I or a pharmaceutically acceptable salt thereof is in a crystalline form characterized by an XRPD pattern as shown in any of FIGS. 1-17.

6. The method of claim 5, wherein Compound I or a pharmaceutically acceptable salt thereof is a hydrobromide salt of Compound I having a particle size distribution corresponding to: D98%: 650-680 .mu.m; D50%: 230-250 .mu.m; and D5%: 40-60 .mu.m; D98%: 370-390 .mu.m; d50%: 100-120 .mu.m; and D5%: 5-15 .mu.m; D98%: 100-125 .mu.m; D50%: 15-25 .mu.m; and D5%: 1-3 .mu.m; or D98%: 50-70 .mu.m; D50%: 3-7 .mu.m; and D5%: 0.5-2 .mu.m.

7. The method of claim 5, wherein the disease is major depressive disorder.
