Disulfiram: what is it and what is it for?
·
Its mechanism of action is the
inhibition of the activity of aldehyde dehydrogenises, an enzyme found in the
liver.
Disulfiram implant is used as an
aversive conditioning treatment for alcohol dependence and comes in tablets of
between 250 mg and 500 mg.
Disulfiram by
itself is not toxic but when taken with alcohol causes many adverse and
unpleasant effects, being the fear of suffering an important point of
treatment, since the objective is to condition the patient to avoid alcohol.
When alcohol is
ingested, it first becomes a chemical called acetaldehyde. Acetaldehyde
decomposes in acetate; for this, the substance aldehyde dehydrogenises must be
active.
Disulfiram
inhibits this substance and, consequently, acetaldehyde cannot be broken down
correctly. This last process is what causes the uncomfortable effects that
encourage the person to avoid alcohol.

The most common
adverse effect of disulfiram is drowsiness, accompanied by fatigue. In
addition, a metallic or garlic-like aftertaste is experienced, but most users
develop tolerance to this effect.
It is also
associated with impotence, especially when taken at a dose of 500 mg per day.
Among other side effects, disulfiram, can cause blurred vision, discoloration,
and inflammation of the skin increased heart rate and changes in mental status.
When alcohol is
used together with disulfiram, symptoms are usually experienced including
redness, headache, nausea, vomiting, and abdominal pain. Preventing these
symptoms from appearing is an important motivation to stop drinking in
alcoholics who undergo treatment with Alcohol Implant.

full recovery; This process can last for months or even years, depending on the
response and motivation of the individual to stop using alcohol.

duration of the activity of disulfiram is 14 days after having interrupted the
treatment and users should avoid alcohol during this period of time so as not
to experience its undesired effects.
