Each tablet for oral use contains ergoloid mesylates USP; a mixture of the methanesulfonate salt of the following hydrogenated alkaloids.
A proportion of individuals over sixty who manifest signs and symptoms of an idiopathic decline in mental capacity (i.e., cognitive and interpersonal skills, mood, self-care, apparent motivation) can experience some symptomatic relief upon treatment with ergoloid mesylates preparations. The identity of the specific trait(s) or condition(s), if any, which would usefully predict a response to ergoloid mesylates therapy is not known. It appears, however, that those individuals who do respond come from groups of patients who would be considered clinically to suffer from some ill-defined process related to aging or to have some underlying dementing condition (i.e., primary progressive dementia, Alzheimer's dementia, senile onset, multi-infarct dementia).
Before prescribing ergoloid mesylates, the physician should exclude the possibility that the patient's signs and symptoms arise from a potentially reversible and treatable condition. Particular care should be taken to exclude delirium and dementiform illness secondary to systemic disease, primary neurological disease, or primary disturbance of mood. Ergoloid mesylates preparations are not indicated in the treatment of acute or chronic psychosis, regardless of etiology (see).
The decision to use ergoloid mesylates in the treatment of an individual with a symptomatic decline in mental capacity of unknown etiology should be continually reviewed since the presenting clinical picture may subsequently evolve sufficiently to allow a specific diagnosis and a specific alternative treatment. In addition, continued clinical evaluation is required to determine whether any initial benefit conferred by ergoloid mesylates therapy persists with time.
The efficacy of ergoloid mesylates was evaluated using a special rating scale known as the SCAG (Sandoz Clinical Assessment-Geriatric). The specific items on this scale on which modest but statistically significant changes were observed at the end of twelve weeks include: mental alertness, confusion, recent memory, orientation, emotional lability, self-care, depression, anxiety/fears, cooperation, sociability, appetite, dizziness, fatigue, bothersome(ness), and an overall impression of clinical status.

Ergoloids and ischaemic strokes; efficacy and mechanism of action. [1995.05]
In this double-blind, randomized study the efficacy of the ergoloid compounds, co-dergocrine mesylate and nicergoline, in the rehabilitation of patients with ischaemic stroke was investigated. A group of 30 patients was treated daily with 60 mg nicergoline, orally, and a second group of 27 patients was given 1.8-6 mg co-dergocrine mesylate, orally or intramuscularly, daily (depending on the time since the initial ischaemic insult) for 6 months...
Ergoloid mesylates ('Hydergine') in the treatment of mental deterioration in the elderly: a 6-month double-blind, placebo-controlled trial. 
A double-blind, placebo-controlled trial was carried out in 97 elderly patients with age-related mental deterioration to assess the efficacy of ergoloid mesylates in improving their symptoms. Patients were allocated at random to receive either 4.5 mg ergoloid mesylates per day or a matching placebo tablet and were followed-up for 6 months after the start of treatment...
