The present disclosure also provides methods for treating disorders susceptible to (Z)-endoxifen, including hormone dependent disorders and mood disorders.
1 . A sustained release composition comprising a therapeutic agent and a sustained release agent, wherein the therapeutic agent is (Z)-endoxifen free base, a polymorph of (Z)-endoxifen, a salt of (Z)-endoxifen, or a combination thereof, and wherein the therapeutic agent has at least two percentage dissolution parameters selected from:
a percentage dissolution of less than 20% at 2 hours;
a percentage dissolution of less than 40% at 7 hours; and
a percentage dissolution of at least 30% at 12 hours,
as measured at 37° C. in simulated gastric fluid at pH 1.2 from hours 0 to 2 and in simulated intestinal fluid at pH 6.8 after 2 hours.
