Bromantane (Ladasten) is an adamantane-related compound investigated for asthenia, a syndrome involving fatigue and weakness. The research below distinguishes observed findings from interpretation.[1.1]
Selected human research: 728 patients with psychoautonomic syndrome and asthenic disorders were analyzed across 28 Russian centers. Ladasten 50–100 mg daily for 28 days, with follow-up one month later; route is not specified in the abstract. Symptoms and quality-of-life scores improved. Adverse effects were reported in 3%, and 0.8% discontinued treatment; no serious adverse effects were reported. No concurrent control group is described in this abstract. Improvement does not establish a placebo-adjusted effect or benefit for healthy users. No concurrent control group is described in this abstract. Improvement does not establish a placebo-adjusted effect or benefit for healthy users.[2.1]

Explore safety questions by system
These are literature filters, not claims that this compound causes each effect. A keyword match is not a confirmed adverse reaction.
Interactions, rare harms, long-term effects and reversibility require separate evidence. Do not infer they are absent when the sources here do not address them.
Identity, names & formulations
Canonical compound: Bromantane · bromantane
Searchable names: Ladasten
Names share a parent research page. Different esters, salts, routes and brands are not assumed to have the same half-life, indication or exposure.
Combination evidence stays attached to the studied combination. It is not automatically assigned to each ingredient.
Understand the evidence types
Read the model and design first, then the population, outcome and limitations. These categories describe evidence, not a best-compound ranking.
Randomized human trials
Compare assigned interventions. Randomization does not by itself establish low bias or relevance to every population.
Controlled human studies
Use a comparison group; allocation and confounding still matter.
Prospective human research
Follows participants forward. It may be observational or interventional, so this is not a separate quality grade.
Observational human research
Describes associations. Confounding can explain differences.
Case reports and series
Useful for unusual events and safety signals, not reliable rates or effect sizes.
Animal research
Can test biology and function in a living model. Human exposure, benefit and safety remain separate questions.
Cell and tissue research
Tests responses in a preparation, including human-derived cells. It is not a human participant trial.
Mechanistic and computational evidence
Helps explain or predict a pathway; predictions need experimental and clinical testing.
Anecdotal reports
Self-reported experiences can generate questions. Product identity, selection bias and other interventions may be uncontrolled.
Systematic reviews synthesize studies and depend on their quality. Preprint status and abstract versus full-paper reading are separate labels. Citation popularity measures attention, not reliability. A study summary is not a formal quality appraisal.
Reference facts checked 2026-09-23. Source scope is listed above; this is not a formal quality appraisal. See each label for full prescribing information.
