Dexamethason se zaměřuje na stres a mechanismy imunitního systému, které jsou základem touhy po alkoholu

28. září 2026 aktualizováno: Helen Fox, Stony Brook University

Dexamethason k cílení na stres a změny imunitního systému během časné abstinence u jedinců s poruchou užívání alkoholu (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.
