Human study
Cortexin chronic cerebral-ischaemia trial
Separate 10 mg and 20 mg intramuscular groups
10-day courses, repeated after 6 months
Fedin et al., randomized study (2018) ↗When results may show
- When change was measured
- Symptoms and cognitive/functional scales were examined across five visits; this was not a healthy-user enhancement trial.
- When to assess
- 10-day courses, repeated after 6 months
- Conditions and limitations
- 189 adults with stage I–II chronic cerebral ischaemia. Intramuscular tissue extract is not a defined under-the-skin peptide or pen product. Small, condition-specific evidence does not define a universal cycle.
- When to stop
- The measured study window is not a validated personal quit rule. Do not increase or prolong exposure because an expected result is absent; severe or persistent reactions need prompt clinical review.
Research timing is descriptive, not a promise or personal instruction. A severe or persistent reaction needs prompt clinical review. This is not medical advice.
