A stimulant drug that the Doctor administers in Waking Moments to keep crew members awake while an alien species attacks Voyager's crew through a shared dream.
Animazine is a stimulant in the stores of Voyager's sickbay, used to keep a patient alert and conscious when sleep would be dangerous.
It plays a part in the Voyager episode Waking Moments. Members of the crew all dream of the same unfamiliar alien and then cannot be woken; the species lives in a permanent dream state and regards waking beings as a threat to be subdued in their sleep. Chakotay uses the technique of lucid dreaming, with the image of Earth's moon as his signal that he is dreaming, to move in and out of the shared dream.
As the few people still awake fight exhaustion, the Doctor, who needs no sleep at all, relies on the stimulant to keep Chakotay on his feet long enough to beam down to the cave where the aliens' sleeping bodies lie and threaten them into releasing the crew.
