How the medicine works (mode of action)?
- Rivastigmine is responsible for improving the mental function such as memory and thinking (cognitive deficits) in dementia associated with Alzheimer’s disease and Parkinson’s disease via
- Increasing the quantity of some natural substance like acetylcholine in the brain.
- Facilitating cholinergic neurotransmission.
- Memory loss and cognitive deficits associated with Alzheimer’s are mainly due to lack of acetylcholine. The deficiency of acetylcholine is principally due to selective loss of cholinergic neurons in the nucleus basalis, cerebral cortex, and hippocampus part of the brain.
- Acetylcholine is a chemical that is responsible for thinking, memory and perception.
- The precise mechanism of action of Rivastigmine is not known but it is postulated that the drug exerts its therapeutic effect by enhancing cholinergic function.
- Rivastigmine belongs to the class of medications known as cholinesterase inhibitors that binds reversibly with cholinesterases (both butyrylcholinesterase and acetylcholinesterase).
- The Rivastigmine interaction with its target enzyme i.e. acetylcholinesterase results in a covalently bound complex that brings about the temporary inactivation of the enzyme.
- As a result, Rivastigmine inactivates cholinesterase (eg. acetylcholinesterase, butyrylcholinesterase), and prevents the hydrolysis of acetycholine. This results in an increased concentration of acetylcholine at cholinergic synapses, which facilitates the cholinergic neurotransmission at the junctions between nerve cells.
- The anti-cholinesterase activity of Rivastigmine is mostly specific for brain acetylcholinesterase and butyrylcholinesterase as compared with those in peripheral tissues.
What are the recommended doses of Rivastigmine?
The doses of Rivastigmine vary depending upon the diseased state, response to treatment, interruption period and specific population.
- Dosing in Alzheimer’s disease: The drug should be taken twice a day (morning and evening) with meals. The recommended dosage of drug as solution and capsules varies from 6 mg to 12 mg per day, administered twice a day.
- Initial Dose: A dose of 1.5 mg twice a day is recommended.
- Dose Titration: The dose of the drug can be increased to 3 mg twice a day only if the drug is well tolerated and after a period of 2 weeks with subsequent increase to 4.5 mg twice a day and 6 mg twice a day only after a minimum of 2 weeks at the previous dose and if well tolerated. The maximum recommended dose is 6 mg twice a day (12 mg once a day).
- Dosing in Parkinson’s disease dementia: The drug should be taken with food in the morning and evening in divided doses. The drug dosage recommended in dementia associated with Parkinson’s disease is 3 mg to 12 mg once a day that is to be administered twice daily (daily doses of 1.5 mg to 6 mg twice a day).
- Initial Dose: A dose of 1.5 mg twice a day is recommended.
- Dose Titration: The dose of the drug can be increased to 3 mg twice a day only if the drug is well tolerated and after a period of 4 weeks with subsequent increase to 4.5 mg twice a day and 6 mg twice a day only after a minimum of 4 weeks at the previous dose and if well tolerated. The maximum recommended dose is 6 mg twice a day (12 mg once a day).
- Interruption of treatment: The treatment is discontinued for several doses (for a period of 3 days or less) in case the patient encounters the side effects such as abdominal pain, vomiting, nausea, loss of appetite etc. The drug treatment is then reinitiated either at the same drug dose or at a lower drug dose level. In case the interruption is for more than 3 days, the treatment should be restarted at 1.5 mg twice daily and titration is carried out as in described for Alzheimer’s disease or Parkinson’s disease.

Does Rivastigmine have any interaction with drugs?
It has been observed that Rivastigmine may interact with or increase or decrease the effect of following drugs. Caution should be taken when co administrating Rivastigmine with one of the following drugs. It is advisable to inform your health care provider if you are taking any of the following medication.
- Beta-adrenergic receptor antagonists (beta-blockers): These are a family of medication that is widely used to treat hypertension, migraine prophylaxis, anxiety, essential tremor, hyperthyroidism, angina pectoris and cardiac arrhythmias. When used in combination with Rivastigmine these drugs have additive bradycardic effects that may increase the heartbeat (especially cardioselective beta-blockers including atenolol). Some of the most common beta blockers which interacts with Rivastigmine are acebutolol, atenolol, labetalol, betaxolol, bisoprolol, nadolol, carvedilol, penbutolol, pindolol, esmolol, metoprolol, nebivolol, propranolol, sotalol, or timolol. Coadministration of Rivastigmine is highly contraindicated and recommended when signs of bradycardia including syncope are present.
- Dopamine-receptor antagonists: These are group of medications that are used to treat stomach and esophageal problems such as nausea and vomiting (especially metoclopramide). Since coadministration of metoclopramide increased the risk of uncontrolled body due to the additive extra-pyramidal adverse reactions.
- Aspirin and Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): The risk of gastrointestinal bleeding (stomach or bowel bleeding) increases when Rivastigmine is coadministered with NSAIDs.
- Cholinomimetic and Anticholinergic Medications: Coadministration of Rivastigmine with other Cholinomimetic medications (e.g., bethanechol, donepezil) potentiate the cholinergic effects and interfere with the activity of anticholinergic medications (e.g., oxybutynin, tolterodine).
This list is not a complete list and there can be many more drugs that can interact with Rivastigmine. It is advisable to ask your health care provider if Rivastigmine may interact with other medicines that you take.
Does Rivastigmine have any interaction with diseases?
Before you begin to take Rivastigmine, it is necessary to discuss any medical condition or allergies you have or any other significant fact. It has been observed that following medical conditions (disease) may interact with Rivastigmine:
- Gastrointestinal Adverse Reactions: It has been observed that use of Rivastigmine can cause gastrointestinal adverse reactions, including significant nausea, anorexia/decreased appetite, vomiting, diarrhea, and weight loss. Prolonged vomiting or diarrhea can be associated with dehydration and other serious outcomes. The incidence and fatal outcome are associated in dose-dependent fashion.
- Allergic Dermatitis: Post-marketing reports of Rivastigmine use have reported the occurrence of disseminated allergic dermatitis irrespective of the route of administration (oral or transdermal). Therefore, it is advisable to stop the treatment immediately if disseminated allergic dermatitis occurs.
- Neurologic Effects: Rivastigmine is principally a cholinomimetics that may potentiate or induce extrapyramidal symptoms such as tremors and deterioration of parkinsonian symptoms. Apart from this, Rivastigmine use may also exacerbate the incidence of seizures, although, seizure activity may also be due to manifestation of Alzheimer’s disease.
- Peptic Ulcers/Gastrointestinal Bleeding: The use of Rivastigmine is associated with increased gastric acid secretion due to its cholinergic activity. Therefore, it is advisable to monitor the patients (especially who have increased risk for developing ulcers) for symptoms of active or occult gastrointestinal bleeding.
- Cardiac Conduction Effects: Because Rivastigmine increases cholinergic activity, use of Rivastigmine may hyper the excitability of the vagus nerve (Vagotonic effect) that can produce bradycardia, decreased heart output, and faintness. The occurrence of bradycardia is more in patients with sick sinus syndrome or other supraventricular cardiac conduction conditions.
- Genitourinary and Pulmonary Effects: It has been speculated that Rivastigmine cholinergic activity may cause urinary obstruction. Furthermore, Rivastigmine use should be under care in patients with a history of asthma or obstructive pulmonary disease.
Where can I get more information?
Your pharmacist can provide more information about Rivastigmine.
Clinical research and current scenario of the drug.
- Clinical studies performed under both in vitro and in vivo conditions suggested that cholinergic activity of Rivastigmine (inhibition of cholinesterase) is not affected by the concomitant administration of N-methyl-D-aspartate receptor antagonist i.e. memantine.
- Toxicity and metabolic studies using animal model suggested the minimal involvement of major cytochrome P450 isozymes in Rivastigmine metabolism. These studies were in accordance with previous observations in humans that suggested no drug interactions related to cytochrome P450.
- Clinical studies using Rivastigmine in North American trial in patients with mild to moderate Alzheimer disease, showed dose-dependent treatment benefit on cognition, function, and activities of daily living.
- Experimental trials have been performed to evaluate the effect of Rivastigmine for dementia with lewy bodies and Parkinson’s disease dementia, delirium, traumatic brain injury, down’s syndrome, supranuclear palsy, and cocaine dependence.
- Clinical trials conducted to analyze the effect of Rivastigmine therapy in AD patients with hallucinations showed better response to Rivastigmine treatment than those without
- Clinical investigation on Rivastigmine transdermal patch suggested that transdermal patches provide continuous drug delivery and, reduce the fluctuations in plasma and central nervous system drug concentrations.
