About NAMENDA XR®
NAMENDA XR (memantine HCl) extended release capsules are a higher dose, once-daily formulation of NAMENDA immediate release indicated for the treatment of moderate to severe dementia of the Alzheimer's type. Its mechanism of action focuses on the glutamate pathway, a target for the treatment of Alzheimer's disease. The efficacy and safety of NAMENDA XR was established in a 24 week, randomized, double-blind, placebo-controlled trial of 677 outpatients on a stable dose of acetylcholinesterase inhibitors (AChEl).
NAMENDA XR 28 mg plus an AChEI demonstrated statistically significant improvement in cognition and global function compared to placebo plus an AChEI. Cognition was measured by the Severe Impairment Battery Scale (2.6 unit mean difference). Global function was measured by the Clinician's Interview-Based Impression of Change Scale (0.3. unit mean difference).
There is no evidence that NAMENDA XR or an AChEI prevents or slows the underlying disease process in patients with Alzheimer's disease.
IMPORTANT SAFETY INFORMATION
- NAMENDA XR is contraindicated in patients with known hypersensitivity to memantine hydrochloride or to any excipients used in the formulation.
Warnings and Precautions
- NAMENDA XR should be used with caution under conditions that raise urine pH (including alterations by diet, drugs, and the clinical state of the patient). Alkaline urine conditions may decrease the urinary elimination of memantine, resulting in increased plasma levels and a possible increase in adverse effects.
- The most commonly observed adverse reactions seen in patients administered NAMENDA XR (28 mg/day) in a controlled clinical trial, defined as those occurring at a frequency of at least 5% in the NAMENDA XR group and at a higher frequency than placebo were headache (6% vs 5%), diarrhea (5% vs 4%), and dizziness (5% vs 1%).
- NAMENDA XR has not been systematically evaluated in patients with a seizure disorder.
- No drug-drug interaction studies have been conducted with NAMENDA XR, specifically. The combined use of NAMENDA XR with other NMDA antagonists (amantadine, ketamine, or dextromethorphan) has not been systematically evaluated and such use should be approached with caution.
Dosing and Administration
- The recommended starting dose of NAMENDA XR is 7 mg once daily. The recommended target dose is 28 mg once daily. The dose should be increased in 7 mg increments to 28 mg once daily. The minimum recommended interval between dose increases is one week and only if the previous dose has been well tolerated. The maximum recommended dose is 28 mg once daily.
- It is recommended that a patient who is on a regimen of 10 mg twice daily of NAMENDA tablets be switched to NAMENDA XR 28 mg once-daily capsules the day following the last dose of a 10 mg NAMENDA tablet. There is no study addressing the comparative efficacy of these 2 regimens.
- It is recommended that a patient with severe renal impairment who is on a regimen of 5 mg twice daily of NAMENDA tablets be switched to NAMENDA XR 14 mg once-daily capsules the day following the last dose of a 5 mg NAMENDA tablet.
- NAMENDA XR should be administered with caution to patients with severe hepatic impairment.
- A target dose of 14 mg/day is recommended in patients with severe renal impairment (creatinine clearance of 5-29 mL/min, based on the Cockcroft-Gault equation).
