Lorazepam is a drug that is used for various purposes. It is sometimes used as a sedative in patients who are recipients of medical ventilation. It is, however, not recommended for use in patients who are critically ill because propofol has been found to have better effects and results.
The drug has an amnesic effect that is relatively potent. This is because of its sedative and anxiolytic effects upon the body. It is mostly used as premedication because of these characteristics. Premedications are drugs that are used for treating a patient before the use of anesthesia.
