Study Notes
Thiopental Sodium
- Chemical name: Sodium 5-ethyl-5-(1-methylbutyl)-2-thiobarbiturate
- Mechanism of action: binds to a distinct binding site at the GABAA receptor, increasing the opening duration of Cl ionophore, and prolonging the post-synaptic inhibitory effect of GABA in the thalamus
Uses of Thiopental Sodium
- Used as a sole anaesthetic agent for short procedures (15 minutes)
- Used for inducing anaesthesia prior to administering other anaesthetic agents
- Used for supplementing regional anaesthesia
- Used for providing hypnosis during balanced anaesthesia with other agents for analgesia or muscle relaxation
- Used for controlling convulsive states during or after inhalation anaesthesia or local anaesthesia
- Used in neurosurgical patients having increased intracranial pressure
- Used for narcoanalysis and narcosynthesis in psychiatric disorders
Stability and Storage Conditions
- Stored at 22°C
- Remains stable and sterile for 6 days and well beyond 7 days at 3°C
Formulations and Brand Names
- Formulations: Injection, Powder, Solution
- Popular brand names: Pentothal, Anesthal, Thiojex, Pentone, Thiosol
Ketamine Hydrochloride
- NMDA receptor antagonist with a potent anaesthetic effect
- Developed as a replacement for phencyclidine by Calvin Stevens
