Heroin on the Hypothalamic-Pituitary-Adrenal Axis

J Clin Psychopharmacol. 2013 Feb 14. [Epub ahead of print]

Acute Effects of Intravenous Heroin on the Hypothalamic-Pituitary-Adrenal Axis Response: A Controlled Trial.

 Heroin administration reduces craving, withdrawal, and anxiety levels and leads to significant decreases in ACTH and cortisol concentrations (P < 0.01).

 After heroin administration, cortisol concentrations did not differ from healthy controls, and ACTH levels were significantly lower (P < 0.01).

 In contrast, when patients receive saline, all hormone levels were significantly higher in patients than in healthy controls (P < 0.01).

Heroin-dependent patients showed a normalized HPA axis response compared to healthy controls when they receive their regular heroin dose.

 These findings indicate that regular opioid administration protects addicts from stress and underscore the clinical significance of heroin-assisted treatment for heroin-dependent patients.
