Selank is authorised as a medicine in Russia for anxiety-related indications, with a Russian-language clinical literature spanning several decades. Independent Western clinical trials and broader regulatory authorisation are limited. It remains a research compound of significant interest in anxiolytic and immunomodulatory studies.
Published studies — concentrated in Russian-language literature — have explored:
Anxiolytic activity: Clinical studies in generalised anxiety disorder cohorts, with reported effects comparable to benzodiazepines but without sedation or dependence patterns.
Cognitive effects: Studies on attention, memory, and cognitive performance in clinical and healthy cohorts.
Immunomodulation: Effects on cytokine expression and immune function, reflecting its tuftsin lineage.
Enkephalin biology: Mechanistic research on endogenous opioid system modulation.
