Etomidate is a medication primarily used for inducing anesthesia in patients undergoing surgery or other medical procedures. It works by enhancing the effects of a neurotransmitter called GABA, which helps to calm the brain and induce sleep. Due to its rapid onset and short duration of action, etomidate is often favored in emergency situations. One of the key benefits of etomidate is its minimal impact on cardiovascular function, making it a safer option for patients with heart issues. However, it can cause side effects such as nausea and adrenal suppression, which may affect hormone production.
