or a pharmaceutically acceptable salt thereof, wherein

R 1 and R 2 are independently selected from H and D, and R 3 -R 20 are H;

wherein the abundance of deuterium in R 1 is at least 30% and the abundance of deuterium in R 2 is at least 30%.

2. The method of claim 1 , wherein the abundance of deuterium in R 1 is at least 50% and the abundance of deuterium in R 2 is at least 50%.

3. The method of claim 1 , wherein the abundance of deuterium in R 1 is at least 50% and the abundance of deuterium in R 2 is at least 90%.

4. The method of claim 1 , wherein R 1 is D.

or a pharmaceutically acceptable salt thereof, wherein R 1 and R 2 are independently selected from H and D, and R 3 -R 20 are H;

wherein the abundance of deuterium in R 1 is at least 30% and the abundance of deuterium in R 2 is at least 90%.

7. The method of claim 6 , wherein R 1 is H.

8. The method of claim 6 , wherein R 1 is D.

9. The method of claim 6 , wherein the deuterium enriched compound is administered as a pharmaceutical composition, the pharmaceutical composition comprising a pharmaceutically acceptable carrier and a therapeutically effective amount of the deuterium enriched compound or a pharmaceutically acceptable salt form thereof.
