(April 2015) (Learn how and when to remove this template message) Part 1 Alice in Wonderland[edit] The first part opens with Alice helping Mother set the table for tea time. Although thankful for her daughter's help, Mother tells Alice that she is still not grown-up enough to join the adults at tea. Alice goes outside to see her sister (played by Natalie's real-life older sister Sharee Gregory), but gets bored of reading a book with no pictures. Her sister tells her that she will understand when she grows up, but Alice thinks she is already grown up (after all, she's seven and a half). While playing with her kitten, Dinah, the White Rabbit comes running by, saying he's late. Wondering where he is going, Alice follows him and tumbles into his rabbit hole. (Unlike the book and most movie versions, this rabbit hole appears to be dark and spooky.) Alice finds herself in a hall with many doors, and all of them locked. On a table is a key which she can use to open one small door. Yet the door is far too small to even fit her head in. A small bottle appears labeled "Drink Me". She comes back to the table and puts it to her lips. Doing this, she shrinks to the right size for the door, but can no longer reach the key to open it. She then sees a small box which she opens and finds a little cake with the words "Eat Me" on it. She then grows to over nine feet tall. Frustrated with the thought of being stuck at nine feet tall, she begins to cry. Her tears fall on the floor and flow under the cracks. The White Rabbit appears, but frightened of the giant Alice runs away dropping his fan and gloves. Using the fan makes Alice shrink again to a size small enough to crawl into one of the cracks, which takes her diving in her pool of tears. While swimming in the pool of her own tears, she meets The Lory Bird, The Dodo Bird and the Mouse, who tells her why he hates dogs and cats ("I Hate Dogs and Cats"). Alice catches up with the White Rabbit. He mistakes Alice for his housemaid Mary Ann and orders her to go get his fan and gloves from his house. While searching his house, Alice curiously finds another "Drink Me" bottle and it makes her sprout to her full nine-foot character once again. Angry at Alice, the rabbit and his friend Pat the Pig try to employ Bill the Lizard to remove Alice by pulling her out the chimney. Having tried unsuccessfully the White Rabbit and Pat begin throwing berries at her which turn into little cakes. She eats one and shrinks to back to size. After running away she meets the Caterpillar who tells her the story ("You are Old, Father William"). She then goes to the house of The Duchess and her pepper loving, plate throwing cook. Finding the house too violent and hateful, she takes the Duchess' baby away, but then it turns into a pig. She meets the Cheshire Cat, who tells her that she can't get out of this land ("There's No Way Home"). He then gives her directions to see either the March Hare or the Mad Hatter, but warns Alice that they, along with everyone else, are mad. Alice finds the Mad Hatter, March Hare, and the Dormouse having an outdoor tea party, and sits down to join them. As tea time entertainment the Mad Hatter, who does not like her version of twinkle, twinkle little star, sings Alice a song of his own ("Laugh"). Upset by the rudeness of the Mad Tea Party, Alice runs off back on her quest for the White Rabbit, and meets a baby fawn in the forest, the only normal thing she's seen so

Context: The mechanism of action, pharmacokinetics, and use of flumazenil in benzodiazepine overdose, as well as in the management of other disease states, are reviewed. Flumazenil interacts at the central benzodiazepine receptor to antagonize or reverse the behavioral, neurologic, and electrophysiologic effects of benzodiazepine agonists and inverse agonists. Flumazenil has been studied for a variety of indications, including as an antidote to benzodiazepine overdose and for awakening of comatose patients, reversal of sedation after surgery and in critically ill patients, and management of hepatic encephalopathy. It improves the level of consciousness in patients with benzodiazepine overdose; however, resedation may occur within one to two hours after administration, so repeated doses or a continuous infusion may be required to maintain therapeutic efficacy. It appears to be effective in reversing sedation induced by midazolam or diazepam, and case reports suggest that it is useful in awakening comatose patients, although its clinical utility is questionable. Flumazenil has proved useful in reversing conscious sedation in critically ill patients, although response may be dose dependent. Animal models indicate that flumazenil is of some benefit in hepatic encephalopathy, but until well-designed clinical trials are conducted, hepatic encephalopathy must be considered an investigational indication for flumazenil. Adverse reactions include CNS manifestations, resedation, cardiovascular effects, seizures, and alterations in intracranial pressure and cerebral perfusion pressure. Hepatic dysfunction results in a substantial change in the pharmacokinetic profile of flumazenil; therefore, dosage adjustment may be necessary in patients with hepatic dysfunction or in those receiving medications that alter flumazenil metabolism. Flumazenil has been shown to reverse sedation caused by intoxication with benzodiazepines alone or benzodiazepines in combination with other agents, but it should not be used when cyclic antidepressant intoxication is suspected. It may be beneficial after surgery when benzodiazepines have been used as part of anesthesia and after a diagnostic or surgical procedure when assessment of CNS function is necessary. 
 Question: Which drug should be used as an antidote in benzodiazepine overdose?

Ex Output:
flumazenil

Context: Trying to snap a three-game losing streak, the 49ers flew to Giants Stadium for a Week 7 brawl with the New York Giants. With QB Alex Smith still recovering from a shoulder injury, back-up Trent Dilfer once again got the start. In the first quarter, the Niners trailed early as Giants QB Eli Manning hooked up with WR Amani Toomer on a 4-yard TD pass (with a missed PAT) for the only score of the period. In the second quarter, San Francisco took the lead with Dilfer completing a 17-yard TD pass to WR Arnaz Battle. However, New York responded with RB Brandon Jacobs getting a 5-yard TD run, while kicker Lawrence Tynes nailed field goals of 29 and 39 yards. In the third quarter, things got worse for the Niners as Giants DE Osi Umenyiora sacked Dilfer, causing a fumble, picked up the loose ball, and ran 75 yards for a touchdown. San Francisco would manage to get a safety as FB Moran Norris blocked a punt, which went out of bounds in the endzone. In the fourth quarter, New York sealed its win with Manning completing a 2-yard TD pass to TE Jeremy Shockey. The Niners ended its day with Dilfer completing a 1-yard TD pass to WR Darrell Jackson (with a failed 2-point conversion).
