Landex (Donepezil Hydrochloride Monohydrate)

Donepezil reversibly blocks acetylcholinesterase, the enzyme that degrades acetylcholine, thereby increasing acetylcholine levels in the brain and enhancing cholinergic neurotransmission, which is reduced in Alzheimer’s disease.

The dosage of Landex is determined individually by the prescribing clinician based on the patient’s clinical condition, response, and tolerability. No fixed regimen is provided here.

Safety of donepezil in pregnancy or lactation has not been established. It should only be used if the potential benefit justifies the potential risk to the fetus or infant, and under medical supervision.

To order Landex, submit an enquiry on the product page at gnhindia.com specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any required import documentation.

Landex (donepezil) belongs to the acetylcholinesterase inhibitor class, similar to rivastigmine and galantamine. Compared with these agents, donepezil is often preferred for its once‑daily dosing and a well‑characterized safety profile, though individual response varies.

Landex should be stored at ambient temperature, below 25 °C, in its original packaging to protect from moisture and light. Keep the product out of reach of children and do not use after the expiry date.

Landex is taken orally, usually with water. It can be taken with or without food, but consistent administration with respect to meals helps maintain steady drug levels. Follow the prescriber’s instructions for timing and any dose adjustments.

Serious risks include bradycardia, heart block, severe liver injury, seizures, and gastrointestinal bleeding. Patients should be monitored for cardiac symptoms, liver function abnormalities, and any signs of bleeding while on therapy.

Landex is contraindicated in patients with known hypersensitivity to donepezil or any excipients, those with severe cardiac conduction disorders, and individuals taking strong anticholinergic medications that could negate its effect.
