Larentine 5 Tablet contains Memantine 5 mg, an N-methyl-D-aspartate (NMDA) receptor antagonist used primarily in the management of moderate to severe Alzheimer's disease. Memantine works by modulating the activity of glutamate, a neurotransmitter involved in learning and memory, thereby helping to regulate abnormal brain activity associated with neurodegenerative conditions. Larentine 5 is indicated to improve cognitive function, memory, attention, and the ability to perform daily activities in patients with Alzheimer's disease. The medication is typically administered orally once or twice daily, with dosage adjustments based on clinical response and tolerability. Common side effects may include dizziness, headache, confusion, and constipation, though it is generally well tolerated. Caution is advised in patients with renal impairment, and dose modifications may be necessary. Larentine 5 should be used under medical supervision, particularly in individuals with a history of seizures or cardiovascular disease. It is not a cure for Alzheimer's disease but may help slow symptom progression and improve quality of life. Concomitant use with other NMDA antagonists or medications affecting renal clearance should be monitored to avoid potential interactions. Regular follow-up is recommended to assess therapeutic efficacy and adverse effects.
