Alzepil, 10 mg 28 pcs.

A selective and reversible inhibitor of acetylcholinesterase, which is the main predominant type of cholinesterase in the brain. In vitro, donepezil inhibits this enzyme more than 1,000 times stronger than butyrylcholinesterase, an enzyme that is mainly outside the CNS.

A single dose of 5 mg or 10 mg in equilibrium is accompanied by a 63.6% and 77.3% inhibition of cholinesterase activity (assessed in the erythrocyte membrane model), respectively. The ability of donepezil hydrochloride to inhibit erythrocyte cholinesterase activity correlates with changes in ADAS-cog scores, which is a sensitive tool for assessing changes in cognitive function. The ability of donepezil hydrochloride to alter the course of concomitant neurological changes has not been investigated. Thus, donepezil cannot be considered to affect disease progression.

The efficacy of donepezil has been investigated in four placebo-controlled studies, two six-month and two one-year studies.

The six-month clinical trial was analyzed using three efficacy criteria after donepezil was completed. They used the ADAS-Cog scale (a measure of cognitive function); the clinician’s impression of change scale based on interviews and data from caregivers (a measure of overall level of function); and the daily activity subscale of the clinical dementia assessment scale (a measure of the patient’s ability to participate in society, perform household chores, favorite activities, and self-care).

Patients who achieved the criteria below were considered to have responded to treatment.

Response = improvement of at least 4 points on the ADAS-Cog scale, no worsening on the CIBIC scale, no worsening on the Daily Activity subscale of the Clinical Dementia Rating Scale.

*p< 0.05, **p< 0.01

Donepezil hydrochloride caused a dose-dependent, statistically significant increase in the percentage of patients who were found to respond to treatment.
