PHARMACY STUDENT NEEDS HELP -- SUBLINGUAL ADMIN OF ROBINUL

I AM A PHARM D STUDENT IN NORTH CAROLINA. I HAVE BEEN INQUIRED OF BY AN INTENSIVE CARE PHYSICIAN ABOUT THE SUBLINGUAL ADMINISTRATION OF ROBINUL INJECTION AND/OR TABLETS. CAN YOU PLEASE HELP ME AND SHOW ME THE LITERATURE CONCERNING THIS BECAUSE I HAVE NOT BEEN ABLE TO FIND THIS INFORMATION ANYWHERE, ALTHOUGH I HAVE HEARD THAT YOU CAN USE THE INJECTION SUBLINGUALLY. THANK YOU FOR YOUR TIME.

SINCERELY,

ASHLEY NASH
