9. The method of claim 1 , wherein the initial dose and each supplemental dose of the compound of formula (I) or a pharmaceutically acceptable salt thereof, is administered to the subject over a time period of one minute or less.
10. The method of claim 1 , wherein the sedation is selected from mild sedation, moderate sedation, deep sedation, procedural sedation, analgosedation, and general anesthesia.
11. The method of claim 10 , wherein the sedation is selected from mild sedation, deep sedation, and general anesthesia.
12. The method of claim 10 , wherein the sedation is mild sedation.
13. The method of claim 10 , wherein the sedation is deep sedation.
14. The method of claim 10 , wherein the sedation is general anesthesia.
15. The method of claim 1 , wherein the sedation ranges from mild sedation to general anesthesia.
16. The method of claim 1 , wherein the sedation ranges from mild sedation to deep sedation.
17. The method of claim 1 , wherein the number of top up supplemental doses administered to the subject is 6 or less.
18. The method of claim 1 , wherein the one or more top doses supplemental doses are administered the subject no sooner than 2 minutes following administration of the initial dose to the subject.
19. The method of claim 1 , wherein the compound of formula (I), or a pharmaceutically acceptable salt thereof, is administered to the subject in the form a saline solution.
20. The method of claim 3 , wherein the dose of the opioid is administered to the subject no earlier than 10 minutes prior to the intravenous administration of the initial dose of the compound of formula (I), or a pharmaceutically acceptable salt thereof, to the subject.
21. The method of claim 1 , wherein the initial dose of the compound of formula (I), or a pharmaceutically acceptable salt thereof, is from about 2 mg to about 10 mg.
22. The method of claim 21 , wherein the initial dose of the compound of formula (I), or a pharmaceutically acceptable salt thereof, is from about 3 mg to about 10 mg.
23. The method of claim 21 , wherein the initial dose of the compound of formula (I), or a pharmaceutically acceptable salt thereof, is from about 3 mg to about 9 mg.
24. The method of claim 21 , wherein the initial dose of the compound of formula (I), or a pharmaceutically acceptable salt thereof, is from about 5 mg to about 8 mg.
25. The method of claim 21 , wherein the initial dose of the compound of formula (I) is from about 2 mg to about 10 mg.
26. The method of claim 25 , wherein the initial dose of the compound of formula (I) is from about 3 mg to about 10 mg.
27. The method of claim 25 , wherein the initial dose of the compound of formula (I) is from about 3 mg to about 9 mg.
28. The method of claim 25 , wherein the initial dose of the compound of formula (I) is from about 5 mg to about 8 mg.
29. The method of claim 25 , wherein the initial dose of the compound of formula (I) is about 5 mg.
30. A method for procedural sedation in a subject, comprising administering intravenously to the subject a dose of a composition comprising 3-[(4S)-8-bromo-1-methyl-6-(2-pyridinyl)-4H-imidazo[1,2-a][1,4]benzodiazepin-4-yl]-propionic methyl ester of formula (I),
or a pharmaceutically acceptable salt thereof, wherein the dose of the compound of formula (I), or a pharmaceutically acceptable salt thereof, does not depend on the body weight of the subject.
31. The method of claim 30 , wherein the dose of the compound of formula (I), or a pharmaceutically acceptable salt thereof, is from about 2 mg to about 10 mg.
32. The method of claim 30 , wherein the dose of the compound of formula (I), or a pharmaceutically acceptable salt thereof, is from about 3 mg to about 10 mg.
33. The method of claim 30 , wherein the dose of the compound of formula (I), or a pharmaceutically acceptable salt thereof, is from about 3 mg to about 9 mg.
34. The method of claim 30 , wherein the dose of the compound of formula (I), or a pharmaceutically acceptable salt thereof, is from about 5 mg to about 8 mg.
35. The method of claim 30 , wherein the dose of the compound of formula (I) is from about 2 mg to about 10 mg.
