💉🧪 Pentothal is a potent intravenous anesthetic commonly used in medical procedures to induce anesthesia and sedation. It belongs to the class of drugs known as barbiturates and acts by depressing the central nervous system, leading to relaxation, unconsciousness, and pain relief. Pentothal has a rapid onset of action and a short duration, making it suitable for short-term surgical interventions or diagnostic tests. Its use requires careful monitoring due to potential side effects such as respiratory depression and cardiovascular instability.
