Sedatives & Hypnotics Flashcards

1
Q

Ok, so what’s the difference between a sedative, a hypnotic, and a general anesthetic?

A

Sedative: Anxiolytic (“inhibit anxiety) – but ideally with minimal effect on motor or mental functions. Hypnotic: Induce sleep (with a much more pronounced CNS depression than sedatives). General Anesthetic: Induce reversible coma – Hypnosis, Amnesia, Analgesia, Muscle relaxation, Attenuation of autonomic reflexes.

29

38
Q

Why cant other barbiturates be used for hypnosis?

A

Half-lifes are too long: they will accumulate during repetitive administration (hence the preferred use of benzodiazepienes)
