Contents of the package and additional information

For what it is usedDezipar

Dezipar is indicated as a substitute treatment in adult patients with moderate to severe Alzheimer's disease adequately controlled with a daily dose of 10 mg of donepezilo and 20 mg of memantina, taken as a free combination.

How it worksDezipar

Dezipar is a combination of an acetylcholinesterase inhibitor (donepezilo) and an NMDA receptor antagonist (memantina). Acetylcholinesterase inhibitors, such as donepezilo, increase the levels in the brain of a substance related to memory (acetylcholine), by means of the decrease in the rate of decomposition of this substance. Memantine hydrochloride, by inhibiting the activity of NMDA receptors, improves the transmission of nerve signals and memory.

Do not take Dezipar

• if you are allergic to hydrochloride of memantine, hydrochloride of donepezil, piperidine derivatives, or any other component of this medication (listed in section 6).
• if you are pregnant or think you may be pregnant.

Warnings and precautions

Consult your doctor before starting to take Dezipar if you have or have had:

• stomach or duodenal ulcers
• history of seizures
• recent myocardial infarction (heart attack), or if you have congestive heart failure or uncontrolled high blood pressure.
• cardiac condition (such as irregular or very slow heartbeats, heart failure, myocardial infarction)
• cardiac condition called "prolongation of the QT interval" or history of certain abnormal heart rhythms called torsade de pointes or if someone in your family has "prolongation of the QT interval"
• low levels of magnesium or potassium in the blood
• seizures
• asthma or chronic lung disease
• difficulty urinating or kidney problems
• liver problems, as Dezipar is not recommended for patients with severe liver insufficiency.

In the above situations, treatment should be closely monitored and your doctor should reevaluate the clinical benefit of Dezipar regularly.

If you have kidney problems, your doctor should closely monitor your renal function and if necessary, adjust the memantine dosage.

If you have renal tubular acidosis (ATR, excess of acid-producing substances in the blood due to renal dysfunction) or severe urinary tract infections, your doctor may need to adjust the medication dosage.

Inform your doctor if you have any liver disease. Dezipar can be used in patients with mild to moderate liver insufficiency. Patients with severe liver insufficiency should not take Dezipar.

You should avoid taking Dezipar with other acetylcholinesterase inhibitors and other cholinergic agonists or antagonists, with medications such as amantadine (for Parkinson's treatment), ketamine (a medication generally used for anesthesia), dextromethorphan (a medication for cough treatment), and other NMDA antagonists.
