VINPOCETINE
(generic name: Cavinton) |
|
|
Vinpocetine (Cavinton) - is a preventive anti-stroke
drug. It also enhance brain blood circulation, improves
memory and hearing (tinnitus). Arteriosclerosis development
in brain is retarding. Vinpocetine improves blood
flow to the brain, makes it easier for the brain to
use glucose and oxygen, and allows the brain to survive
longer and better after periods of oxygen deprivation.
Several brain boosters (ginkgo biloba, vitamin E,
phosphatidylserine, to name just a few) are known
to help restore failing memory, but Vinpocetine dramatically
enhances memory in even healthy individuals. It also
acts as a potent neuroprotective supplement.
Clinical evidence exists that,
in addition to its brain boosting properties, Vinpocetine’s
ability to improve blood flow also helps protect brain
and heart function; prevent macular degeneration,
(a leading cause of blindness in the elderly); improve
hearing and inner ear problems; and even lessen depression
and fatigue.

Stroke represents the third common
cause of death and hospitalization. However, there
are yet no drugs that have reliable effects on acute
stroke in Japan. Therefore, the development of new
drugs that can support patients is required. There
are various candidate drugs for acute stroke such
as antithrombotic agents, anticoagulants, thrombolytic
agents, neuroprotectants, and so on. Recently clinical
trials suggest that aspirin may improve outcome, although
these studies demonstrated a modest benefit of aspirin.
Abciximab (ReoPro) is a human/mouse monoclonal antibody
directed against the platelet receptor glycoprotein
IIb/IIIa. It appears to be safe and might improve
functional outcome. The large randomized trails were
started to test the hypothesis that thrombolysis by
an intravenous administration of a recombinant tissue
type plasminogen activator (rtPA) could restore cerebral
blood flow and improve patient outcome in acute ischemic
stroke. These results can support the use of intravenous
rtPA for stroke treatment within 3 h after onset,
but not beyond 3 h. Development of an effective neuroprotective
agent for the treatment of acute stroke remains problematic.
Antioxidants, MCI-186 and ebselen, have finished phase
III of clinical trials in Japan and were effective.
We hope that efficacious drugs for acute stroke can
be used for patients.

Studies in laboratory animals indicate
that the rate and extent of functional recovery after
focal brain injury can be modulated by drugs affecting
specific central neurotransmitters. Preliminary clinical
studies suggest that similar drug effects may occur
in humans recovering from stroke. Combined with principles
derived from the laboratory, these clinical studies
provide important insights to guide the rational design
of trials aimed at determining the clinical use of
this approach to improving poststroke recovery.

The efficacy and safety profiles
of Amlodipine (5-10 mg once daily) and nifedipine
retard (20-40 mg twice daily) were compared in 111
hypertensive patients (sitting DBP in 95-115 mmHg)
during eight weeks of treatment in a randomised double-blind
parallel group study. BP was measured 22-24 hours
after the daily dose of Amlodipine and 10-12 hours
after a dose of nifedipine retard. Baseline sitting
BPs of 175/105 mmHg and 168/104 mmHg were significantly
reduced (P < 0.05) to 157/93 mmHg and 151/92 mmHg
at the end of treatment in response to mean daily
doses of Amlodipine 7.3 mg and nifedipine retard 58.9
mg. There were no clinically significant changes in
heart rate with either treatment. Three patients in
the Amlodipine group and five patients in the nifedipine
retard group could not be considered in analysis.
The total numbers of adverse events (considered related
or possibly related to treatment) (42 vs. 36) as well
as the numbers of patients experiencing such events
(22 vs. 22) were similar in the Amlodipine and nifedipine
retard treated groups, respectively, but with a greater
incidence of headaches in response to nifedipine retard
and of oedema in response to Amlodipine. Five patients
in each treatment group discontinued therapy due to
such events. Overall the results showed once daily
Amlodipine as equivalent to twice daily nifedipine
retard in the management of mild to moderate hypertension.

The aim of the study was to evaluate,
in a population of elderly hypertensives, the efficacy
for 24 hours, the safety and the effects on carbohydrates
and lipids metabolism of Amlodipine (A) and nitrendipine
(N). After a 3-week placebo wash-out, 50 patients
with mild to moderate essential hypertension (HBP)
or isolated systolic hypertension (ISH), were randomized
in 4 groups treated with once-daily A 5,10mg or N
10,20mg increasing until patients responded to treatment.
All subjects were submitted to a 24-hour non invasive
ambulatory blood pressure monitoring (ABPM) at the
start of the study (t0) and after four weeks of therapy
(t4). It was registered a mean daily reduction in
the pressure load of 15.0% in group A, 14.1% in group
B, 13.9% in group C and 15.6% in group D; (p <
0.001). 82% of the patients treated with A and 85%
treated with N resulted "responder". The
metabolic parameters considered showed no significant
changes. The overall incidence of adverse effects
were temporary and extremely limited (2%). As monotherapies,
Amlodipine and nitrendipine are both suitable for
the management of mild to moderate hypertension in
elderly.
