Deapril-ST - General Information

Deapril-ST is a dihydrogenated ergot (Claviceps purpurea) derivative alkaloid used as a vasodilator agent. Ergoloid Mesylate is the only vasodilator that has shown mild benefits in the treatment of vascular dementia.


Pharmacology of Deapril-ST

Ergoloid Mesylate may increase cerebral metabolism and blood flow. The role of this medication in the therapy of dementia is controversial. A recent controlled study in patients with Alzheimer's disease found that there was no advantage to the use of ergoloid mesylates compared to placebo, suggesting that ergoloid mesylates may lower scores on some cognitive and behavioral rating scales. Further study is needed to determine the risk-benefit profile of ergoloid mesylates in the treatment of dementia.

Additional information about Deapril-ST

Deapril-ST Indication: For use as an adjunct therapy for patients with dementia
Mechanism Of Action: Deapril-STs act centrally, decreasing vascular tone and slowing the heart rate, and acts peripherally to block alpha-receptors. One other possible mechanism is the effect of ergoloid mesylates on neuronal cell metabolism, resulting in improved oxygen uptake and cerebral metabolism, thereby normalizing depressed neurotransmitter levels.
