Nepezil (Donepezil Hydrochloride)

Donepezil reversibly inhibits the enzyme acetylcholinesterase, which normally breaks down the neurotransmitter acetylcholine. By blocking this enzyme, the drug raises acetylcholine levels in the central nervous system, helping to restore communication between nerve cells that is compromised in Alzheimer’s disease.

The specific dose of Nepezil is determined by the prescribing clinician based on the patient’s clinical condition, response, and tolerability. Dosage adjustments are made individually, and patients should follow the prescriber’s instructions without self‑adjusting the amount.

Donepezil is classified as a pregnancy category where use is only recommended if the potential benefit justifies the potential risk to the fetus. It is also excreted in breast milk, so breastfeeding mothers should discuss risks and alternatives with their healthcare provider.

To request Nepezil, submit an enquiry on the product page at gnhindia.com, specifying the required quantity.

Nepezil (Donepezil) belongs to the acetylcholinesterase inhibitor class, similar to rivastigmine and galantamine. Compared with these agents, Donepezil generally offers once‑daily dosing and a broader evidence base for mild to moderate disease, though individual response and tolerability vary.

Nepezil tablets should be stored at ambient temperature, below 25 °C, in the original packaging to protect from moisture and light. Keep the product out of reach of children and avoid storing in humid or excessively hot environments.

Nepezil is taken orally, usually once daily, with or without food. The tablet should be swallowed whole with a glass of water. Patients should follow the exact schedule prescribed by their healthcare professional to maintain consistent drug levels.

Serious risks include bradycardia or heart block, severe gastrointestinal bleeding, liver injury, seizures, and rare but life‑threatening skin reactions such as Stevens‑Johnson syndrome. Patients should seek immediate medical attention if they experience fainting, severe abdominal pain, jaundice, or rash.

Nepezil is contraindicated in patients with known hypersensitivity to Donepezil or any tablet excipients, those with severe hepatic impairment, and individuals with a history of significant cardiac conduction disorders unless closely monitored. It should also be used with caution in patients with active peptic ulcer disease.
