Tricordrazine

Tricordrazine was a potent stimulant, originally derived from cordrazine, and commonly used in resuscitation in the 24th century. The drug was highly potent; 25 ccs of the drug was enough to kill a Klingon. It was also used as an anti-seizure medication. 

In 2365, Doctor Katherine Pulaski administered five milligrams of tricordrazine to William Riker, followed by another dose when his life signs were failing fast. 

In 2366, Doctor Beverly Crusher treated Mary Warren with tricordrazine after she was injured on Mintaka III, and later gave instructions for increased levels to be administered. 

Similarly, in an alternate timeline that same year, Captain Rachel Garrett was treated with tricordrazine and Crusher ordered the levels to be boosted.

In 2368, Crusher attempted to use tricordrazine to revive Worf after he experienced heart failure, following a risky surgery using the genitronic replicator to repair his damaged spinal column.
