Rivastigmine 1.5 mg capsule plays a crucial role in slowing down the progression of memory loss and confusion associated with dementia. Many patients and caregivers prefer this medication for its effectiveness and manageable dosage form. Produced by Steris Healthcare, PYRITIGMIN RIVA 1.5 ensures high-quality standards, providing patients with a reliable treatment option.

What is Rivastigmine 1.5 mg Capsule?

Rivastigmine 1.5 mg Capsule is a medicine that belongs to the class of drugs known as cholinesterase inhibitors. It works by increasing the levels of certain brain chemicals (acetylcholine) that are involved in memory, thinking, and reasoning.

This medicine is commonly prescribed for:

  • Mild to moderate Alzheimer’s disease

  • Parkinson’s disease-related dementia

By improving communication between nerve cells, Rivastigmine 1.5 mg helps slow down the progression of memory loss and improves quality of life.

Rivastigmine Mechanism of Action

The mechanism of action of Rivastigmine is based on its ability to block the enzymes acetylcholinesterase and butyrylcholinesterase. These enzymes normally break down acetylcholine, a neurotransmitter essential for memory and cognition.

By inhibiting these enzymes, Rivastigmine increases acetylcholine levels in the brain, which helps improve nerve communication and reduces symptoms of dementia.

Rivastigmine Structure – A Scientific Insight (For the Curious Minds)

The rivastigmine structure is a carbamate derivative chemically known as (S)-N-ethyl-3-[(1-dimethylamino)ethyl]-N-methylphenyl-carbamate. This molecular structure allows it to cross the blood-brain barrier efficiently and bind to the cholinesterase enzymes in the brain, offering targeted action.

While the structure may not be something patients interact with directly, it's good to know that the design of the molecule contributes to its therapeutic effectiveness.
