What are the side effects of rivastigmine?

The main adverse effects associated with the use of rivastigmine are gastrointestinal. The primary symptoms are nausea and vomiting. These acute effects primarily occur during the initial dose-escalation phase of therapy upward dose titration of the drug to achieve a therapeutic dose. These events can be minimized using a slow titration schedule and taking the medication with food if prescribing an oral formulation. In a study done to analyze the safety and tolerability of cholinesterase inhibitors used to treat Alzheimer dementia, researchers found rivastigmine to be the drug to have the highest rate of gastrointestinal side effects. [8]

How to follow up on rivastigmine?

Patients on rivastigmine, and other anticholinergic medications, should have close follow-up with the primary physician taking care of them. Clinicians should work closely with nurses to keep a proper follow-up on patients to ensure optimal therapy and be aware of the potential for adverse effects. Physicians can also work closely with pharmacists to help optimize treatment and prescribe the best regimen to their patients to achieve optimal therapy for their diagnoses; the pharmacist can consult on whether rivastigmine is best suited for the patient at hand or not. Nursing and pharmacy must both emphasize the importance of strict compliance to patients, as a lack of compliance can be devastating to therapy and, subsequently, their life. Concerns about compliance need to be brought to the prescribing clinician's attention immediately. All members of the interprofessional healthcare team are responsible for providing the best care to their patients as well as being on the lookout for adverse effects. An interprofessional team employing strategies, like those outlined here, will result in the best outcomes. [Level 5]

What are the two enzymes that hydrolyze acetylcholine?

In the brain, two different cholinesterase enzymes hydrolyze acetylcholine. These two enzymes are acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). AChE is mainly present at the synaptic nerve junctions, as well as areas that have high activity in the cerebral cortex. BuChE is found in the glial cells of the brain and helps mediate cholinergic activity. As humans age, the activity of both of these cholinesterase enzymes increases. In pathologic states like Alzheimer disease and Parkinson disease, the upregulation of cholinesterase enzymes is much higher than normal. Unlike other cholinesterase inhibitors, rivastigmine has been shown to inhibit both of these enzymes, causing an overall increase in acetylcholine . [5]

The numbers were impressive: seven unconfounded, double-blind, randomised, controlled trials (comprising a total of 3450 patients); the data was at low risk of bias for randomisation and allocation; all dementia included was of the Alzheimer’s type; pills, patches and placebo were compared in various combinations; all trials assessed rivastigmine use for at least 12 weeks – a useful time period since rivastigmine use can be associated with a 12 week titration period as patients develop tolerance and minimise adverse events such as nausea.

What tests were used to test rivastigmine?

More subtle ways would be needed to test rivastigmine; questionnaires and psychometric tests were used aplenty. For cognitive effects, the Alzheimer’s Disease Assessment Scale (ADAS-Cog), the Mini-Mental State Examination (MMSE), the Severe Impairment Battery (SIB) questionnaire were among those used; for behavioural effects, tools included the Cohen-Mansfield Agitation Inventory (Cohen-Mansfield, 1995) (commonly used in nursing homes to assess agitation). Clinicians were also asked to give a ‘global rating’ of patients’ change in function after receiving rivastigmine. I’ve done that with Cyril, and I’ve seen total decline. But these patients were different: of the seven trials included in the final analysis (n=3450), six recruited patients with mild to moderate dementia – could rivastigmine provide a rescue in this cohort?

What is the enzyme that breaks down acetylcholine?

Donepezil, rivastigmine and galantamine all prevent an enzyme called acetylcholinesterase from breaking down acetylcholine. This means there is a higher concentration of acetylcholine in the brain, which leads to better communication between nerve cells. This may ease some symptoms of Alzheimer’s disease for a while.

Why does acetylcholine get lost?

Acetylcholine helps to send messages between certain nerve cells. In Alzheimer’s disease some of the nerve cells that use acetylcholine are also lost. Because of these changes in the brain, symptoms of Alzheimer’s disease get worse over time.

All three cholinesterase inhibitors work in a similar way. However, one drug might be better for someone than another. For instance, a person may have fewer side effects from one drug.
