Possible Interaction: Ethanol and Levodopa



Research Papers that Mention the Interaction

A single injection of L-dopa tended to enhance ethanol withdrawal reactions and 5HTP tended to suppress it.

When L-dopa at 60 mg/Kg was administered to alcohol chronic rats, inhibition reached about 30%.

The same two TIQs have been detected … brain and urine of mammals administered alcohol and a second …—for example, L-dopa or pyrogallol; and it has been proposed that these Pictet–Spengler condensation products (of dopamine and dopaldehyde or acetaldehyde, respectively) may be responsible for addiction in alcoholism2–5.

Chronic alcohol drinking led to a decrease in dopamine and DOPAL (a direct dopamine metabolite and a high-affinity ADH substrate) levels in the striatum, while immunization neutralized this effect.

The in vitro study revealed that in presence of l-menthol (2%, W/W), ethanol (20 and 40%, V/V) accelerated transdermal penetration of l-dopa with an increase of its percentages.

Topical application of a dopamine agonist, bromocriptine, or L-beta-3,4-dihydroxyphenylalanine , significantly reduced the extent of damage induced by subsequent application of 70% ethanol.

Carlsson and Lindqvid demonstrated that the intraperitoneal administration of ethanol is associated with a significant increase in the accumulation of L-3,4dihydroxyphenylalanine (dopa) in the brain following inhibition of L-aromatic amino acid decarboxylase.

To explain this phenomenon the possibility might be considered that ethanol causes a decrease in the plasma concentration of other amino acids competing with L-dopa for the same carrier system (Oldendorf 1975; Pardridge & Oldendorf 1977; Wurtman & Fernstrom 1976; Carlsson & Lindqvist 1978).
We have recently reported that the passage of exogenously administered L-dopa through the blood-brain barrier in rat is increased after previous administration of ethanol (Eriksson et a1 1979).

Administration of L-DOPA and pCPA, together, produced a smaller augmentation of ethanol effects.
Pretreatment with L-DOPA produced a marked prolongation of ethanol narcosis with a concomitant large increase in whole brain dopamine (DA).
