Introduction

Cognitive decline and dementia are some of the most challenging health conditions faced by patients and families worldwide. Disorders like Alzheimer’s disease and Parkinson’s disease dementia gradually affect memory, thinking, and the ability to perform everyday tasks, impacting overall quality of life.To help manage these symptoms, doctors often prescribe cholinesterase inhibitors, a class of medications that work by enhancing the levels of key brain chemicals involved in memory and learning.One such trusted medicine is Rivastigmine 3 mg Capsule, marketed under the brand name PYRITIGMIN RIVA 3 by Steris Healthcare.This medicine is especially important for patients in whom lower doses (like Rivastigmine 1.5 mg) are tolerated, and treatment needs to be stepped up for better control of dementia-related symptoms.

Composition of Rivastigmine 3 mg Capsule

• Active Ingredient: Rivastigmine 3 mg

• Brand Name: PYRITIGMIN RIVA 3

• Form: Capsule

• Category: Cholinesterase Inhibitor

• Manufacturer: Steris Healthcare

Each capsule of PYRITIGMIN RIVA 3 contains 3 mg of Rivastigmine as the active drug, along with carefully selected excipients (inactive ingredients) that ensure drug stability, absorption, and effectiveness.

What is Rivastigmine 3 mg?

Rivastigmine 3 mg is a central nervous system (CNS)-acting drug designed to manage dementia symptoms caused by Alzheimer’s disease and Parkinson’s disease.

• It belongs to the class of medicines called cholinesterase inhibitors.

• Rivastigmine works by blocking the breakdown of acetylcholine, an important neurotransmitter involved in learning, memory, and thinking.

• Increasing acetylcholine levels helps improve communication between brain cells, which can slow the progression of dementia and improve daily functioning.

PYRITIGMIN RIVA 3 is usually prescribed after the patient has adjusted well to lower doses (such as 1.5 mg twice daily). It provides a balance of higher efficacy while minimizing side effects.

Rivastigmine 3 mg Uses

Rivastigmine 3 mg capsules are widely prescribed for:

1. Alzheimer’s Disease Dementia

• Improves memory, judgment, attention span, and daily activity performance.

• Helps slow down the progression of symptoms.

2. Parkinson’s Disease Dementia

• Enhances attention and recall ability.

• Reduces confusion, hallucinations, and behavioral disturbances in Parkinson’s-related dementia.

3. Supportive Cognitive Therapy

• Maintains mental alertness in dementia patients.

• Improves the patient’s quality of life by supporting independence in daily tasks.

Rivastigmine Mechanism of Action (MOA)

Rivastigmine works through a dual enzyme inhibition mechanism:

1. Inhibition of Acetylcholinesterase

   • This enzyme normally breaks down acetylcholine, a brain chemical vital for memory and learning.

2. Inhibition of Butyrylcholinesterase

   • Provides an added effect, making Rivastigmine effective in a broader range of dementia symptoms compared to some other drugs in its class.

 By inhibiting both enzymes, Rivastigmine increases acetylcholine availability in the brain, improving nerve communication and supporting cognitive function.

Rivastigmine 3 mg Dosage and Administration

• Starting Dose: Patients generally begin with 1.5 mg twice daily.

• Titration: If tolerated, the dose is increased to 3 mg twice daily.

• Administration Tips:

  • Swallow capsules whole with a glass of water.

  • Take with meals to minimize gastrointestinal discomfort.

  • Do not crush or chew the capsules.

 Important: Dosage adjustments should only be made by a healthcare professional. Stopping suddenly can worsen dementia symptoms.
