Indication |
For use as an inhalation agent for induction and/or maintenance of anesthesia for inpatient and outpatient surgery in adults. |
Pharmacodynamics |
Desflurane is a general inhalation anesthetic. It induces muscle
relaxation and reduces pains sensitivity by altering tissue
excitability. It does so by decreasing the extent of gap junction
mediated cell-cell coupling and altering the activity of the channels
that underlie the action potential. |
Mechanism of action |
Desflurane induces a reduction in junctional conductance by
decreasing gap junction channel opening times and increasing gap
junction channel closing times. Desflurane also activates calcium
dependent ATPase in the sarcoplasmic reticulum by increasing the
fluidity of the lipid membrane. It also appears to bind the D subunit of
ATP synthase and NADH dehydogenase. Desflurane also binds to and
agonizes the GABA receptor, the large conductance Ca2+ activated potassium channel, the glycine receptors, and antagonizes the glutamate receptors. |
Absorption |
