Drug Name Antabuse

Blockade of cardiac impulse conduction, as evidenced by impaired AV conduction or cardiac arrest (countermeasure: injection of epinephrine). Depression of excitatory processes in the heart, while undesired during local anesthesia, can be put to therapeutic use in cardiac arrhythmias (p. 134). Forms of local anesthesia.
Depending on the cell population affected, this synaptic inhibition translates into a depressant or excitant effect (B). Effects of opioids (B). The analgesic effect results from actions at the level of the spinal cord (inhibition of nociceptive impulse transmission) and the brain (attenuation of impulse spread, inhibition of pain perception). Attention and ability to concentrate are impaired.

 

This allows brief procedures to be carried out or to prepare the patient for inhalational anesthesia (intubation). Administration of the volatile anesthetic must then be titrated in such a manner as to counterbalance the waning effect of the injectable agent.
The unchanged drug reaches the arterial blood and the kidneys, where it is filtered. With hydrophilic drugs, there is little binding to plasma proteins (protein binding increases as a function of lipophilicity), hence the entire amount present in plasma is available for glomerular filtration. A hydrophilic drug is not subject to tubular reabsorption and appears in the urine.
