DISEASE EVIDENCE MAP / CHECKED 5 OCTOBER 2026

Stroke research.
Outcomes, in context.

Where peptides and related compounds have shown signals of benefit, where results are neutral, and where the evidence is still experimental.

Educational only. Not medical advice. Seek qualified healthcare help for any medical condition. Suspected stroke is an emergency: call emergency services immediately. Experimental compounds must not delay emergency stroke assessment or proven care.
WHAT HAS ACTUALLY BEEN MEASURED?

Some positive findings. No simple winner.

Improved arm movement, a cognitive-test change, a smaller infarct in a rat and reduced mortality are different claims. This map keeps them separate. The human evidence below predominantly concerns ischemic stroke; it must not be transferred to hemorrhagic stroke or used to rank these compounds as interchangeable treatments.

HUMAN STROKE EVIDENCE

Cerebrolysin ↗

The most developed stroke trial collection here, with conflicting results across settings.

CARS reports an upper-limb recovery benefit; CASTA’s primary endpoint was neutral. The Cochrane acute-stroke review found no demonstrated mortality benefit and a nonfatal serious-adverse-event signal.

Source 1 · Source 2 · Source 3

HUMAN STROKE EVIDENCE

Cortexin ↗

Positive functional reports, with important limits on certainty.

ESCORT and smaller comparisons report improvements. Other records are uncontrolled or compare active formulations. They do not establish a survival benefit or a preferred treatment schedule.

Source 1 · Source 2 · Source 3

HUMAN STROKE EVIDENCE

Semax ↗

Human neurological-recovery signals alongside extensive mechanistic work.

The acute comparison and rehabilitation study report favorable changes, but allocation, effect sizes and safety need fuller appraisal. Rat protein or gene expression is a different evidence dimension.

Source 1 · Source 2 · Source 3

HUMAN STROKE EVIDENCE

Actovegin ↗

A cognition-specific trial signal, not established overall stroke recovery.

ARTEMIDA reported better cognitive scores at six months. A systematic review found uncertain patient-important benefit; recurrent-stroke safety requires attention.

Source 1 · Source 2

HUMAN STROKE EVIDENCE

Piracetam / Nootropil ↗

An aphasia signal does not demonstrate independence or survival benefit.

A rehabilitation trial reported language improvement without demonstrated daily-activity benefit. Acute-stroke review evidence remains insufficient.

Source 1 · Source 2

HUMAN STROKE EVIDENCE

Phenotropil ↗

Limited early-recovery observations.

The outpatient report describes changes during treatment, with no adequate untreated comparison and worse tolerability at higher exposure. This cannot establish stroke efficacy.

Source 1

Why the reviews can disagree

Acute treatment, early rehabilitation and later recovery recruit different patients and measure different outcomes. A positive motor-scale result does not contradict a finding of no demonstrated survival benefit. Pooling trials does not create new independent patients.

The 2023 Cochrane review included seven trials of Cerebrolysin or Cortexin. Its mortality estimate was RR 0.96 (95% CI 0.65–1.41). The nonfatal serious-adverse-event estimate, RR 2.39 (1.10–5.23), concerns Cerebrolysin; it must not be assigned to Cortexin. Review and scope ↓

Two newer Cerebrolysin reviews are retained under “Needs reconciliation”: one has inconsistent significance reporting and possible overlapping CARS publications; the other has incompatible sample denominators. Their favorable claims are not treated as confirmed updates. 2025 review ↓ · 2026 review ↓

2023 · Cerebrolysin for acute ischaemic stroke

English abstract
Human stroke

Acute ischemic stroke · systematic review

Review

Cochrane review: 7 RCTs, including one Cortexin trial with 272 participants

Survival / safetyFunction / independence

The pooled mortality analysis of Cerebrolysin or Cortexin found probably little or no difference (RR 0.96, 95% CI 0.65–1.41; 6 trials, 1,689 participants).

No demonstrated survival benefit. Cerebrolysin-specific nonfatal serious-adverse-event signal; not a Cortexin-specific risk estimate.
Study limitations
  • The pooled estimate is not Cortexin-only.
  • The potential increase in nonfatal serious adverse events concerned Cerebrolysin and should not automatically be assigned to Cortexin.

Population / setting
50 stage II patients (5 men, 45 women); 70-day active treatment and 45-day follow-up
What was checked
Publisher methods and outcome descriptions checked; no untreated comparator.
Limitations & review scope
  • Uncontrolled treatment cohort; expectation, repeated testing and concomitant care can affect outcomes.
  • Questionnaire improvement is not evidence about wearable sleep stages.
  • Strong similarities to the 2025 stage II group warrant overlap checks before any pooling.

50 patients with chronic cerebral ischemia and comorbidities
What was checked
English/Russian abstract checked. No wearable sleep-stage results are inferred.
Limitations & review scope
  • Clinical population differs from healthy maritime shift workers.
  • Before/after change does not isolate a treatment effect.
  • Questionnaires cannot validate the personal WHOOP REM/SWS observations.

BIBLIOGRAPHY / ORIGINALS / OPEN QUESTIONS

What still needs to be recovered

This is a curated map of Molekul’s collection plus targeted follow-up searches, not an exhaustive systematic review of all stroke medicines. Records were screened for stroke and cerebral ischemia, then separated by actual population and model. Cardiac or intestinal ischemia, altitude tolerance and generic neuroprotection are not direct stroke evidence.

Picamilon, chronic-ischemia Cortexin reports, Cerluten and the Phenotropil asthenia program remain adjacent. For other catalogued preparations—including Bemitil, Bromantane, Selank, DSIP and Hypoxen—this map does not presently contain verified direct human stroke efficacy data. That is a collection gap, not proof that no publication exists.

  • Recover full Semax trial methods, numerical outcomes and adverse-event tables.
  • Reconcile Cortexin cohort overlap, allocation methods and modern standard-care comparators.
  • Reconcile the 2025 and 2026 Cerebrolysin review tables against their original trial populations.
  • Recover GZK-111 focal-stroke originals separately from CPG studies and pharmacokinetic records.
  • Obtain missing Picamilon and Bemitil cerebral-injury originals before assigning outcomes.
  • Separate long-term disability, quality of life, recurrent stroke and survival from short-term scale or biomarker changes.
