Pentobarbital is a short-acting barbiturate, which is a type of central nervous system depressant. Think of it as a volume-down button for your brain and body. It slows down brain activity and can cause sedation, hypnosis, and anesthesia. Medically, it's used to treat seizures, insomnia, and sometimes as a veterinary anesthetic. Due to its potential for abuse and overdose, it is carefully regulated. Overdoses can cause slowed breathing, lowered heart rate, and even death. It's also sometimes used in assisted suicide or euthanasia.
