Is donazepil problematic for patients with serious respiratory illness?

The only medication I can find is Donepezil which helps to improve mental function with people with Alzheimer's disease, and I can not find any match for Donazepil.

If Donepezil is the one you asking about, this is what the literature of Drugs.com states:

Before taking this medicine
You should not use donepezil if you are allergic to donepezil or certain other drugs. Tell your doctor if you are allergic to any medicines.

Tell your doctor if you have ever had:

a heart rhythm disorder;

a stomach ulcer;

urination problems;

asthma or other breathing disorder;

liver or kidney disease;

a seizure; or

trouble swallowing tablets.

Tell your doctor if you are pregnant or breast-feeding.
