Patent Claims:	1. A method for the prevention or treatment of nausea or emesis induced by radiation or by a cancer chemotherapeutic agent in a mammal in need thereof which comprises the administration to the mammal of an effective amount of a compound which is 2-(R)-(1-(R)-3,5-bis(trifluoromethyl)phenyl)ethoxy)-3-(S)-(4-fluoro)phenyl -4-(3-(5-oxo-1H,4H-1,2,4-triazolo)methylmorpholine, or a pharmaceutically acceptable salt thereof. 2. The method of claim 1 wherein the mammal is a human. 3. The method of claim 1 wherein the nausea or emesis is induced by radiation. 4. The method of claim 1 wherein the nausea or emesis is induced by a cancer chemotherapeutic agent which is cisplatin. 5. The method of claim 1 wherein the nausea or emesis is induced by a cancer chemotherapeutic agent which is cyclophosphamide. 6. The method of claim 1 wherein the nausea or emesis is induced by a cancer chemotherapeutic agent which is doxorubicin. 7. The method of claim 1 wherein the nausea or emesis is induced by a cancer chemotherapeutic agent which is daunorubicin. 8. The method of claim 1 wherein the nausea or emesis is induced by a cancer chemotherapeutic agent which is etoposide. 9. A method for the prevention or treatment of nausea or emesis induced by radiation or by a cancer chemotherapeutic agent in a mammal in need thereof which comprises the administration to the mammal of an effective amount of: a compound which is ##STR28## or a pharmaceutically acceptable salt thereof. 10. The method of claim 9 wherein the mammal is a human. 11. The method of claim 9 wherein the nausea or emesis is induced by radiation. 12. The method of claim 9 wherein the nausea or emesis is induced by a cancer chemotherapeutic agent which is cisplatin. 13. The method of claim 9 wherein the nausea or emesis is induced by a cancer chemotherapeutic agent which is cyclophosphamide. 14. The method of claim 9 wherein the nausea or emesis is induced by a cancer chemotherapeutic agent which is doxorubicin. 15. The method of claim 9 wherein the nausea or emesis is induced by a cancer chemotherapeutic agent which is daunorubicin. 16. The method of claim 9 wherein the nausea or emesis is induced by a cancer chemotherapeutic agent which is etoposide. 17. A method for the prevention or treatment of post-operative nausea and vomiting in a mammal in need thereof which comprises the administration to the mammal of an effective amount of a compound which is 2-(R)-(1-(R)3,5-bis(trifluoromethyl)phenyl)ethoxy)-3-(S)-(4-fluoro)phenyl- 4-(3-(5-oxo-1H,4H-1,2,4-triazolo)methylmorpholine, or a pharmaceutically acceptable salt thereof. 18. A method for the prevention or treatment of post-operative nausea and vomiting in a mammal in need thereof which comprises the administration to the mammal of an effective amount of a compound which is: ##STR29## or a pharmaceutically acceptable salt thereof.
