Vinpocetine is a chemical derived from vincamine, a constituent found
in the leaves of common periwinkle plant, Vinca minor. Vinpocetine is
used in about 35 countries in the treatment of stroke and vascular dementia.
Its action is to dilate blood vessels to enhance blood flow to specific
regions of the brain as well as to reduce damage from free radicals by
improving oxygen utilization. In Europe, vinpocetine is marketed as a
drug called Cavinton for the treatment of various cerebral insufficiency
conditions. It improves cerebral metabolism (glucose and oxygen uptake),
increases ATP concentration, and selectively increases blood flow to the
brain (without lowering blood flow to other parts of the body); and reduces
blood clotting by making red blood cells more pliable and inhibiting platelet
aggregation. Vinpocetin is also known as a memory enhancer; a treatment
for Alzheimer’s disease; a treatment for stroke; it improves circulation
(especially to the brain); and it is a powerful antioxidant.
Research studies on vinpocetine have shown that it enhances overall brain
function and cognitive ability in people recovering from stroke, Alzheimer's
disease, and age-related declines in memory. It provides significant improvements
in cognitive function in patients suffering from mild to moderate dementia
and in stroke patients, it significantly improved the transport of glucose
(both uptake and release) in the brain and especially in the brain tissue
around the area damaged by stroke. These changes appeared to be related
to increased blood in the entire region in and around the area of damage.
Thousands of patients with different cerebrovascular diseases have shown
improvement (75-85% of patients) on measures of cognitive function with
the use Cavinton in Europe, over the past 10-20 years.
Dosage: Typical dosage recommendations for vinpocetine
are 5-1p0mg, taken 2-3 times per day with meals (to increase absorption
and reduce gastrointestinal discomfort).
Side Effects: Side effects of vinpocetine are quite
rare, typically minor and disappear with discontinuance of consumption.
Rarely, side effects such as gastrointestinal upset; low blood pressure
(hypotension), dry mouth, insomnia, headaches and heart palpitations (rapid
heart beat) have been reported.
