DLB is considered to be one of the major types of dementia worldwide, alongside Alzheimer’s disease and vascular dementia.

Nearly 400,000 people in the Philippines are affected by dementia, the company said.

Earlier in 1999, Aricept was initially launched as a treatment for Alzheimer’s disease in the Philippines.

Later, the medication obtained approval to treat vascular dementia, and for other formulations including orally disintegrating tablets.

Developed by Eisai and Pfizer, Aricept acts as a centrally acting reversible acetylcholinesterase inhibitor.

The application was submitted in November 2015 to seek approval for DLB in the Philippines and is based on the clinical trial data from Japan. It was subsequently approved in February this year.

Additionally, a similar application is currently undergoing regulatory review in Thailand.
