WHAT _MACMENTA _IS USED FOR
_Macmenta _
contains the active
substance memantine hydrochloride. It
belongs to a group of medicines known
as anti- dementia medicines.
_Macmenta _
is used for the treatment of patients

HOW _MACMENTA _WORKS
Memory loss in Alzheimer’s disease is
due to a disturbance of message signals
in the brain. The brain contains so-

receptors that are involved in
transmitting nerve signals important in
learning and memory.

_Macmenta _
acts on these NMDA-
receptors improving the transmission
of nerve signals and the memory.

PHARMACOLOGICAL ACTION:
PHARMACOKINETICS:
Absorption
Memantine has an absolute bioavailability of approximately 100%. Tmax
is between 3 and
8 hours. There is no indication that food influences the absorption of
memantine.
Distribution
Daily doses of 20 mg lead to steady-state plasma concentrations of
memantine ranging
from 70 to 150 ng/ml (0.5 - 1 µmol) with large interindividual
variations. When daily doses
of 5 to 30 mg were administered, a mean cerebrospinal fluid
(CSF)/serum ratio of 0.52 was
calculated. The volume of distribution is around 10 l/kg. About 45% of
memantine is bound
to plasma-proteins.

Biotransformation
In man, about 80% of the circulating memantine-related material is
present as the parent
compound. Main human metabolites are N-3,5-dimethyl-gludantan, the
isomeric mixture of
4- and 6-hydroxy-memantine, and 1-nitroso-3,5-dimethyl-adamantane.
None of these
metabolites exhibit NMDA-antagonistic activity. No cytochrome P 450
catalysed
metabolism has been detected in vi
