Effect of Cyclandelate on Dementia

The treatment of cerebrovascular insufficiency and its many symptoms in the ever-increasing numbers of the aged, is of major concern to physicians engaged in such care. Despite past skepticism as to the degree of efficacy of cerebral vasodilators, there is renewed interest in this form of therapy. Our investigation was designed to assess the effectiveness of cyclandelate, under strict double-blind conditions, in 58 geriatric patients. The cyclandelate and placebo groups (32 and 26 patients respectively) received either 1,600 mg/day of cyclandelate in fractional doses, or identical-appearing placebo capsules--over a period of 12 weeks. During the initial examination and every four weeks thereafter, patients were assessed for possible changes in vital signs and for evidence of adverse reactions. In addition, the Sandoz Clinical Assessment-Geriatric (SCAG) and the Nurses Observation Scale for Inpatient Evaluation (NOSIE) were completed, with particular attention to symptom clusters. A final global assessment was made in which the physician rated patients according to their overall clinical condition. The results of our study and analysis indicate that cyclandelate is a safe and effective agent for treating certain symptoms of senility in properly selected patients, provided the therapy is carried on for at least eight weeks and, if indicated, for a longer period. Clinical evidence suggests that the prudent use of this drug may definitely delay deterioration.

The Safety and Lack of Efficacy of Vinpocetine in Alzheimer's Disease

Thal

Salmon

Lasker

et al. 1989

Fifteen Alzheimer patients were treated with increasing doses of vinpocetine (30, 45, and 60 mg per day) in an open-label pilot trial during a one-year period. Patients were assessed seven times both on and off drug with: the Buschke Selective Reminding Task, a letter fluency test, a category fluency test, the Boston Naming Test, a cognitive capacity screening examination, and a clinical global impression. Vinpocetine failed to improve cognition on psychometric testing or overall functioning, as measured by the clinical global impression, at any dose tested. Patients showed significant decline in most measures during the course of the study, at the same rate as a matched control group, consistent with progressive dementia. There were no significant side effects from drug therapy. We conclude that vinpocetine is ineffective in improving cognitive deficits and does not slow the rate of decline in individuals with Alzheimer's disease.

“…One such drug, cyclandelate (Cyclospasmol, Ives Laboratories Inc), has a clearly demonstrated effect on the cerebral circulation (1–3). However, clinicians have had difficulty in relating these physiologic effects with clinical improvement, and the results of several clinical studies have varied from strongly positive (4–6) to equivocal (7) or even negative (8).…”

Cyclandelate in the Treatment of Senility: A Controlled Study

Capote

Pakikh

1978

Elderly patients often manifest a variety of symptoms (e.g., depression, memory loss, irritability, hostility), categorized as "senility" or "senile dementia," which are difficult to treat and represent a major therapeutic challenge to the geriatrician. This investigation was designed to assess, under double-blind conditions, a drug often prescribed for these symptoms--cyclandelate. In a 16-week study, 58 elderly patients were randomly assigned to two groups and received either 1600 mg of cyclandelate daily or identical-appearing placebo capsules. Initially, the every four weeks thereafter, the patients were examined for changes in vital signs and for adverse reactions, also, the Sandoz Clinical Assessment-Geriatric (SCAG) Scale and the Nurses Observation Scale Inpatient Evaluation (NOSIE) were completed. At the final evaluation, a physician's global rating was obtained. Our data suggest that cyclandelate is a safe and moderately effective treatment for certain symptoms of senescence in carefully selected patients.
