Pharmacological prophylactics against stress-induced affective disorders in females
Methods for prophylactically treating a stress-induced affective disorder or stress-induced psychopathology in a subject are provided. Also provided are methods for inducing and/or enhancing stress resilience in a subject. In certain embodiments, an effective amount of (R,S)-ketamine or (2R, 6R)-hydroxynorketamine ((2R, 6R)-HNK) is administered to a female or male subject prior to a stressor.
1. A method for preventing or delaying a stress-induced affective disorder or stress-induced psychopathology in a female subject, or for inducing and/or enhancing stress resilience in a female subject, the method comprising administering a pharmaceutic composition to the female subject prior to a stressor, within a specific time window, wherein the pharmaceutic composition comprises an effective amount of an agent selected from the group consisting of (R,S)-ketamine, (2R,6R)-hydroxynorketamine ((2R,6R)-HNK), and a pharmaceutically acceptable salt thereof, wherein the effective amount of the agent administered to the female subject is no greater than 70% of an effective amount of the agent administered to a male subject, and wherein the stress-induced affective disorder or stress-induced psychopathology comprises depressive-like behavior, anxious behavior, or combinations thereof.
2. A method for preventing or delaying a stress-induced affective disorder or stress-induced psychopathology in a female subject, or for inducing and/or enhancing stress resilience in a female subject, the method comprising administering a pharmaceutic composition to the female subject prior to a stressor, within a specific time window, wherein the pharmaceutic composition comprises an effective amount of an agent selected from the group consisting of (R,S)-ketamine, (2R,6R)-hydroxynorketamine ((2R,6R)-HNK), and a pharmaceutically acceptable salt thereof, wherein the pharmaceutic composition is administered to the female subject at a time point T f prior to a stressor, wherein T f is no greater than 70% of a time point T m prior to a stressor for administration to a male subject, and wherein the stress-induced affective disorder or stress-induced psychopathology comprises depressive-like behavior, anxious behavior, or combinations thereof.
3. The method of claim 1 , wherein the effective amount of the agent administered to the female subject is no greater than 60% of the effective amount administered to a male subject.
4. The method of claim 1 , wherein the pharmaceutic composition is administered to the female subject about 48 hours to about 3 weeks prior to a stressor.
5. The method of claim 1 , wherein the pharmaceutic composition is administered to the female subject about 1 week prior to a stressor.
6. The method of claim 1 , wherein the pharmaceutic composition is administered to the female subject about 3 days prior to a stressor.
7. The method of claim 1 , wherein the pharmaceutic composition is administered to the subject once prior to a stressor.
8. The method of claim 1 , wherein the pharmaceutic composition is administered orally, intravenously, intranasally, or via injection to the subject.
9. The method of claim 1 , further comprising administering an effective amount of an anti-depressant, an anxiolytic, or combinations thereof.
10. The method of claim 1 , further comprising administering an effective amount of a selective serotonin reuptake inhibitor (SSRI), or a pharmaceutically acceptable salt or derivative thereof.
11. The method of claim 1 , further comprising administering an effective amount of fluoxetine, paroxetine, sertraline, lithium, riluzole, prazosin, lamotrigine, ifenprodil, or combinations thereof.
12. The method of claim 1 , wherein the subject is a human.
