Vinpocetine
Vinpocetine
A synthetic compound derived from periwinkle that enhances cerebral blood flow, memory, and cognitive function.
Vinpocetine is a semi-synthetic derivative of vincamine, an alkaloid from the periwinkle plant (Vinca minor). It's been used in Europe for decades to treat cerebrovascular disorders and cognitive impairment. It works primarily by increasing cerebral blood flow, enhancing glucose and oxygen utilization in the brain, and providing neuroprotection. It also has anti-inflammatory and phosphodiesterase-inhibiting properties.
Mechanisms of Action
Cerebral Blood Flow
Increases blood flow to the brain
Neuroprotection
Protects neurons from damage
PDE Inhibition
Inhibits phosphodiesterase enzymes
Recommended Dose
10-30mg daily in divided doses
Loading: Not required
Optimal Timing
- With food (improves absorption)
- Divided into 2-3 doses
- Morning and early afternoon
Take with food
Best Form
Vinpocetine capsules or tablets
Standard vinpocetine is well-absorbed with food. Usually sold in 5-10mg capsules.
Duration
Minimum: 4 weeks
Optimal: 12 weeks
Cycling: 8-12 weeks on, 2-4 weeks off
Note: Fat-soluble; absorption improved with food. Take earlier in day to avoid sleep interference.

“Therefore, further large and well-designed studies are needed to support the evidence.© 2023 John Wiley & Sons Ltd.”
Key Findings:
- Of these, 65% were rated critically low using AMSTAR2.
- Of 90 unique outcomes, 41 (45.6%) were statistically significant based on random effects model (p ≤ .05).
- The suggestive evidence supported benefits of Chinese herbal medicine (CHM) plus pharmacotherapy (WMD:1.84; 95% CI: 1.34, 2.35) and Vinpocetine (WMD: -0.94; 95%CI: -1.50, -0.38) on improving cognitive function assessing by Montreal Cognitive Assessment and Syndrom-Kurz-Test, respectively.
- Moreover, suggestive evidence supported benefit of Huperzia serrata on improving Activities of Daily Living (WMD:-7.18; 95%CI: -9.12, -5.23).

Key Findings:
- Among them, scutellarin, pinocembrin, puerarin, hydroxysafflor yellow A, salvianolic acids, rosmarinic acid, borneol, bilobalide, ginkgolides, ginsenoside Rd, and vinpocetine show great potential in clinical ischemic stroke treatment.

- Further research warranted to confirm findings
Perng CH et al. • Psychopharmacology (2018)
“The most effective intervention for dementia available is symptomatic treatment for vascular dementia.”
Key Findings:
- The pooled standardized mean difference of the treatment effects on cognitive dysfunction was 0.439 (95% confidence interval 0.374, 0.504).
- The most effective intervention for dementia available is symptomatic treatment for vascular dementia.
- Antipsychotic treatment for dementia alleviates cognitive dysfunction less effectively than does symptomatic treatment.
- Alternative therapies are also effective at present.
Panda PK et al. • Neurocritical care (2022)
“Vinpocetine has some promising efficacy in patients with ischemic stroke when used in the acute stage in reducing the disability, but presently there is not enough evidence to suggest that it also reduces case fatality.”
Key Findings:
- The number of patients with death or significant disability was lower in the vinpocetine group than that in the placebo group at both 1 and 3 months (relative risk 0.80, 95% confidence interval [CI] 0.65-0.99 and relative risk 0.67, CI 0.48-0.92, p = 0.04 and 0.02, respectively).
- The degree of disability in participants at 1 month and 3 months was also lower in vinpocetine group than that in the placebo group (standardized mean difference (SMD) 0.49, 95% CI 0.03-0.95 and SMD 1.22, CI 0.23-2.24, p = 0.001 and 0.04, respectively).
- Change in mini-mental state examination score compared with baseline at trial enrolment was also better in the vinpocetine group than in the placebo group (pooled weighted mean difference 0.92, 95% CI 0.02-1.82, p = 0.04).

Key Findings:
- From 6 to 12 months and from 0 to 12 months there were significant differences with a tendency towards improvement, indicating that the aforementioned deterioration not only stopped, but that with the use of vinpocetine, the hearing capacity improved.
- It is concluded that Vinpocetine helps to stop hearing impairment and even improve hearing.Copyright © 2021 The Authors.
