4.2 Posology and application form
Posology / application frequency and duration:
Adults / seniors:
The treatment starts with a single dose of 5 mg per day. The earliest clinical responses to treatment
and for achieving steady-state concentrations of donepezil hydrochloride 5
Dosage of mg / day should be maintained for at least one month. Dosage of 5 mg daily for one month
assessed the clinical response provided by DOZYL, the dose of 10 mg per day
It can be upgraded. The highest recommended daily dose is 10 mg. Doses above 10 mg / day
have not been examined in clinical trials.
If treatment is interrupted, a beneficial decrease in the beneficial effects of DOZYL is observed.
After a sudden interruption of treatment, any "rebound" effect or withdrawal effect
It was encountered.
Method of Application:
DOZYL should be taken orally once a day and just before bedtime.
Additional information on special populations
Renal insufficiency: Since the clearance of donepezil hydrochloride is not affected by these conditions,
a dose program similar to patients with renal impairment may be administered.
Hepatic insufficiency: possible exposure to mild to moderate hepatic insufficiency
dose adjustments should be made according to individual tolerability. Stable alcoholic cigar
In a study involving 10 patients, the DOZYL clearance, age and gender
compared to 10 healthy individuals who were mated.
Pediatric population: Donepezil hydrochloride reveals efficacy and safety in children
it is not recommended to use it in children.
Geriatric population: Originally the association of the pharmacokinetics of DOZYL with age
No study has been done to investigate. However, Alzheimer's
the mean plasma concentrations followed in elderly patients are higher in young healthy volunteers
is comparable to what is seen.
DOZYL donepezil hydrochloride, piperidine derivatives or derivatives thereof
is contraindicated in patients known to be hypersensitive to any substance.
4.4 Special warnings and precautions for use
The treatment establishes a diagnosis of Alzheimer type dementia and is experienced in treating the disease
be initiated and guided by a physician. Diagnosis is based on accepted guidelines (eg,
DSM IV, ICD 10). Donepezil therapy is the only treatment
should be initiated when there is a responsible person (patient relatives, caregiver etc) who can check.
As long as the patient benefits from the medication, the treatment should continue. Therefore,
the clinical benefits of donepezil should be reassessed for a period of time. Therapeutic effect
when there is no evidence of its existence it should be decided to stop the medicine. the people
the response they will give to the donepezil is unpredictable.
Donepezil hydrochloride can be used for other dementia types and other memory disorders (eg Amnesty
Mild cognitive impairment).
Anesthesia: Donepezil hydrochloride, a cholinesterase inhibitor,
succinylcholine type may increase muscle relaxation.
Cardiovascular states: Cholinesterase inhibitors cause heart disease due to pharmacological effects
may cause vagotonic effects (such as bradycardia) on the pulse. Potential to see this effect
"sick sinus syndrome", other supraventricular disorders such as sinoatrial or atrioventricular block
may be particularly important for patients with impaired cardiac conduction.
Reports of syncope and convulsions are available. When these patients are examined, heart block or
should be considered on the long sinus pause.
Gastrointestinal conditions: Cholinomimetics can increase gastric acid production. Ulcer
story or non-steroidal anti-inflammatory drug (NSAID) sites such as ulcers
Patients with high developmental risk should be closely monitored in terms of the indication. With this
In clinical studies comparing donepezil hydrochloride with placebo, peptic ulcer
or no increase in the incidence of gastrointestinal bleeding.
Genitourinary system: Donepezil hydrochloride can not be observed in clinical trials
Together, cholinomimetics can lead to bladder outlet obstruction.
Central nervous system: Seizures: Cholinomimetics leading to generalized convulsions
are believed to be carrying potential. However, seizures are also indicative of Alzheimer's disease
can. Cholinomimetics have the potential to induce or enhance extrapyramidal indications
Pulmonary system: Depending on the cholinomimetic effects, cholinesterase inhibitors
should be used with caution in patients with a history of obstructive pulmonary disease.
Donepezil hydrochloride, with other acetylcholinesterase (AChE) inhibitors, cholinergic system
agonist or antagonist should be avoided.
Mortality in vascular dementia clinical trials: High-probability or possible vascular
6-month 3-month study of individuals who meet the NINDS-AIREN criteria for dementia (VaD)
clinical trial was conducted. NINDS-AIREN criteria, dementia completely vascular
to identify patients caused by causes and Alzheimer's disease patients
out of work.
When the mortality rates in these three VaD studies are combined, donepezil hydrochloride
mortality rate (1.7%) in the placebo group as numerical value
(1.1%) compared to the previous year. However, this result was not statistically significant.
Mortality in patients using donepezil hydrochloride or placebo may be due to various vascular
of the underlying vascular diseases, such as the elderly
is an expected result for the population.
Analysis of vascular events, both fatal and non-fatal, was performed in the donepezil hydrochloride group
compared with placebo.
When Alzheimer's disease trials were combined (n = 4146), these studies showed that vascular dementia
(n = 6888) were included in the placebo group
the mortality frequency in the donepezil hydrochloride group was calculated numerically
Neuroleptic malignant syndrome (NMS): NMS is a disease threatening life and hyperthermia, muscle
rigidity, autonomic instability, variable consciousness status, serum creatinine phosphokinase levels
characterized by ascension; in addition to myoglobinuria (rhabdomyolysis) and acute renal
failure may also be seen. NMS associated with donepezil use, particularly concurrent antipsychotic
reported in infrequent cases. If the patient points to the NMS
when symptoms are present or when there is no other clinical manifestation of NMS
If unexplained high fever occurs, donepezil treatment should be discontinued.
This drug contains lactose. Rare hereditary galactose intolerance, Lapp lactose insufficiency or
patients with glucose-galactose malabsorption problems should not use this drug.
4.5 Interactions with other medicinal products and other forms of interaction
Simultaneous use of donepezil hydrochloride and other cholinesterase inhibitors
It should be avoided.
Donepezil hydrochloride and / or any of its metabolites may be administered to humans in the presence of theophylline,
cimetidine, digoxin, thioridazine, risperidone and sertraline.
Donepezil hydrochloride metabolism, digoxin, cimetidine, thioridazine, risperidone, and
is not affected by simultaneous use with sertraline.
In a study of patients with Parkinson's disease who received optimal treatment with L-Dopa / carbidopa, 21
day of donepezil hydrochloride administration L-Dopa or carbidopa blood levels
it has no effect. No effect was seen on motor activity in this study. In vitro
Studies have shown that in donepezil metabolism, cytochrome P450 isoenzyme CYP3A4 and less
has also shown that isoenzyme CYP2D6 is involved. In vitro drug interaction studies,
Ketoconazole, a CYP3A4 inhibitor, and quinidine, a CYP2D6 inhibitor, donepezil
metabolism. For this reason, this and other CYP3A4 inhibitors
(such as itraconazole and erythromycin) and CYP2D6 inhibitors (such as fluoxetine)
metabolism. In a study of healthy volunteers, ketoconazole
the average donepezil concentrations increased by 30%. These increases,
than the increase in ketoconazole on other agents sharing the CYP-3A4 system
and it is unlikely that there will be clinical interest. Donepezil administration ketoconazole
has no effect on pharmacokinetics.
Enzyme inducers such as rifampicin, phenytoin, carbamazepine and alcohol, donepezil levels
It may decrease. Since the prophylactic effect of the inhibiting or inducing effect is unknown,
combinations should be used with caution. Donepezil hydrochloride anticholinergic activity
have the potential to interact with medicines they have. At the same time, succinylcholine, other
neuromuscular junction blocking agents or cholinergic agonists or cardiac delivery
synergistic activity with concurrent therapy with drugs such as beta-blocker agents
There is also potential.
