Dexamethason mod stress og immunsystemets mekanismer, der ligger til grund for alkoholtrang

28. september 2026 opdateret af: Helen Fox, Stony Brook University

Dexamethason til at målrette mod stress og immunsystemændringer under tidlig afholdenhed hos personer med alkoholmisbrug (AUD)

This is a double-blind, placebo-controlled, proof of concept laboratory study to recruit N=70 (35 Males / 35 Females) non-treatment seeking, heavy drinkers with alcohol use disorder (AUD). It is hypothesized that randomization to 1.5mgs dexamethasone versus placebo will decrease alcohol craving during stress by decreasing basal cortisol, increasing anti-inflammatory cytokine levels and potentially normalizing the immune response to stress.

Tidsramme
Alcohol craving as assessed using subjective report following stress exposure
Tidsramme: Change from baseline to +5 minutes following stress exposure

The 8-item Alcohol Urges Questionnaire (AUQ) will be used to measure alcohol craving. There are 8 items, each with a Likert scale response from 1 to 7 (1: Strongly Disagree, 7: Strongly Agree). Total possible score of 56. The higher the score the higher the alcohol craving
