Halothane is used for induction and maintenance of general anesthesia.


What is Halothane?

Halothane is an anesthetic. Its numbing effect is based on the action of multiple ion channels present in the cell membrane. This leads to the reduction of nerve impulse transmission, respiratory function and cardiac contraction. Halothane’s immobilizing effects have been linked to potassium channels present in certain neurons (such that use the neurotransmitter acetylcholine). It is also speculated that this drug interacts with glutamic acid receptors and calcium channels.


How should Halothane be taken?

Halothane is administered via inhalation.
