Vistagen is developing the spray as a hormone-free option for managing women’s health issues including vasomotor symptoms associated with menopause, premenstrual dysphoric disorder, dysmenorrhea and migraine.

Pherines represent a new class of compounds aimed at treating psychiatric and neurological disorders through neurocircuitry-focused mechanisms.

The neuroscience-focused biopharmaceutical company is engaged in the development and commercialisation of therapies for psychiatric and neurological disorders.

Its pherine drug candidates have demonstrated favourable safety profiles in all studies completed.

In 2023 the company obtained a Notice of Allowance from the Canadian IP Office for a patent related to the use of AV-101 in Parkinson’s disease (PD) patients.

The treatment reduces the sudden uncontrolled movements, or dyskinesia, caused by using the PD medication levodopa.
