Classification of General Anaesthetics ||PharmaEasyNotes || @Pharmacy

General anaesthetic
Classification-1



The general anesthetic is classified into three types based on the method of administration.

i) Inhalation Anaesthetics
Inhalation anesthetics could be either volatile, liquids, or gases, and they are administered through process eg. Ether, Ethyl chloride, Cyclopropane, Halothane, Nitrous oxide.

ii) Intravenous Anaesthetics
Intravenous Anesthetics cause unconsciousness when administered parenterally.
eg. Thiopental Sodium, Ketamine Hydrochloride, Methohexital Sodium.
iii) Basal Anaesthetics
Basal Anaesthetics are agents induce the state of unconsciousness but the depth of unconsciousness not enough for surgical procedure.
They are often used to induce basal anaesthesia before the administration of inhalation anaesthetics.
eg. Fentanyl Citrate, Paraldehyde, Tribromo ethanol.

II) Classification-II
The general anesthetics are also classified according to their nature at room temperature.

i) Volatile inhalation general anesthetics
(a) Gases - Cyclopropane, Ethyl chloride, Nitrous oxide.
(b) Liquids - Diethyl ether, Halothane, Chloroform, Trichloroethane.

ii) Non-volatile general anaesthetics
(a) Barbiturates- Thiopental Sodium, Methohexital Sodium
(b) Non-Barbiturates- Propanidid, Propofol, Ketamine Hydrochloride.

Receptor - Receptor Families || Pharma Easy Notes || @Pharmacy

Image
Classification All membrane-bound receptors belong to one of the three following systems families based on their structure and function. ( LGKI ) L igand-gated ion channels G - Protein-coupled receptor K inase-linked receptors I ntracellular receptors 1. Ligand-gated ion channels Ion channels are protein complexes that traverse the cell membrane and form a tunnel through it. The function of an ion channel is - to allow the flow of ions across the cell membrane and there are specific ion channels for sodium, Potassium, Calcium, and chloride ions. Without ion tunnels, ions could not cross the fatty cell since many enzyme-catalyzed reactions are dependent on ionic concentration. In the resting state, the ion channel is closed and the receptor's binding site is unoccupied . The signal to open the ion channel comes from the chemical messenger which binds to the receptors and causes it to change shape which travels through the entire ion channel. The proteins making up the ion channe
