Context: The Queen's Royal Irish Hussars, abbreviated as QRIH, was a cavalry regiment of the British Army formed from the amalgamation of the 4th Queen's Own Hussars and the 8th King's Royal Irish Hussars in Hohne, West Germany in 1958.

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: Energy, or the ability to do work, can exist in many different forms. The photo in Figure 17.8 represents six of the eight different forms of energy that are described in this lesson. The guitarist gets the energy he needs to perform from chemical energy in food. He uses mechanical energy to pluck the strings of the guitar. The stage lights use electrical energy and give off both light energy and thermal energy, commonly called heat. The guitar also uses electrical energy, and it produces sound energy when the guitarist plucks the strings. For an introduction to all these forms of energy, go to this URL: . For an interactive animation about the different forms of energy, visit this URL: After you read below about different forms of energy, you can check your knowledge by doing the drag and drop quiz at this URL: . Mechanical energy is the energy of an object that is moving or has the potential to move. It is the sum of an objects kinetic and potential energy. In Figure 17.9, the basketball has mechanical energy because it is moving. The arrow in the same figure has mechanical energy because it has the potential to move due to the elasticity of the bow. What are some other examples of mechanical energy? Energy is stored in the bonds between atoms that make up compounds. This energy is called chemical energy, and it is a form of potential energy. If the bonds between atoms are broken, the energy is released and can do work. The wood in the fireplace in Figure 17.10 has chemical energy. The energy is released as thermal energy when the wood burns. People and many other living things meet their energy needs with chemical energy stored in food. When food molecules are broken down, the energy is released and may be used to do work. Electrons are negatively charged particles in atoms. Moving electrons have a form of kinetic energy called electrical energy. If youve ever experienced an electric outage, then you know how hard it is to get by without electrical energy. Most of the electrical energy we use is produced by power plants and arrives in our homes through wires. Two other sources of electrical energy are pictured in Figure 17.11. The nuclei of atoms are held together by powerful forces. This gives them a tremendous amount of stored energy, called nuclear energy. The energy can be released and used to do work. This happens in nuclear power plants when nuclei fission, or split apart. It also happens in the sun and other stars when nuclei fuse, or join together. Some of the suns energy travels to Earth, where it warms the planet and provides the energy for photosynthesis (see Figure The atoms that make up matter are in constant motion, so they have kinetic energy. All that motion gives matter thermal energy. Thermal energy is defined as the total kinetic energy of all the atoms that make up an object. It depends on how fast the atoms are moving and how many atoms the object has. Therefore, an object with more mass has greater thermal energy than an object with less mass, even if their individual atoms are moving at the same speed. You can see an example of this in Figure 17.13. Energy that the sun and other stars release into space is called electromagnetic energy. This form of energy travels through space as electrical and magnetic waves. Electromagnetic energy is commonly called light. It includes visible light, as well as radio waves, microwaves, and X rays (Figure 17.14). The drummer in Figure 17.15 is hitting the drumheads with drumsticks. This causes the drumheads to vibrate. The vibrations pass to surrounding air particles and then from one air particle to another in a wave of energy called sound energy. We hear sound when the sound waves reach our ears. Sound energy can travel through air, water, and other substances, but not through empty space. Thats because the energy needs particles of matter to pass it on. Energy often changes from one form to another. For example, the mechanical energy of a moving drumstick changes to sound energy when it strikes the drumhead and causes it to vibrate. Any
