Generic Exelon (Rivastigmine 1.5 mg) guide:
Exelon pills – what are they?
Exelon is one of the trade names of the medication substance Rivastigmine that was developed and patented in the early 1990s. Nowadays it is sold under a variety of trade names because the formula isn’t protected by the patent anymore. It means that basically any pharmaceutical company can make the drugs with the same formula as Exelon but they have to name their products differently. Fortunately, you can easily obtain a cheaper version of the medication without even knowing its other trade names if you buy Generic Exelon. This is a standard name used by sellers, pharmacists, and doctors to talk about the other versions of the medications which are sold under other names but have the same composition as the brand-name drug which name is contained in this “code” name.
The active substance of the medication Exelon and its generics is an acetylcholinesterase inhibitor used in the treatment of Alzheimer's disease and dementia in Parkinson's disease. Read further to know when exactly the medication is prescribed and how does it render its effect.
What is the principle of action of Exelon?
The active substance of the preparation marketed under the brand name Exelon is a selective inhibitor of acetylcholinesterase of the brain of the carbamate type. It is considered that it promotes the cholinergic transmission, slowing down the degradation of acetylcholine released from cholinergic neurons with unbroken function. It selectively raises the level of acetylcholine in the cerebral cortex and hippocampus. Thus, it improves the cognitive function impaired due to the failed cholinergic transmission that is present in dementia related to Alzheimer's or Parkinson's disease.
Rivastigmine interacts with target enzymes and forms a covalent binding with them which temporarily deactivates the enzymes. The inhibition of cholinesterase can lead to a delay in the formation of fragments of the protein beta-precursor of amyloid and the formation of amyloid plaques that are characteristic for Alzheimer's disease.
In healthy young men, taking a dose of 3 mg orally reduces the activity of acetylcholinesterase in the cerebrospinal fluid by approximately 40% during the first 1.5 hours. The enzyme activity returns to the initial values at about 9 hours after reaching the maximum inhibition effect. In patients with Alzheimer's disease, the inhibition depends on the dose.
The medication is well-absorbed when taken by mouth. Its bioavailability is around 30-40%. The maximum concentration in the blood is achieved within one hour of intake. The active substance is metabolized by the hydrolysis with the participation of esterases. Then, it is mainly excreted in urine (around 99%) and feces.

The pills should be taken twice a day – one dose in the morning and another one in the evening during meals. The pills must be swallowed entirely without chewing.
The initial treatment dose is 1.5 mg two times a day. If the drug is well-tolerated not sooner, in two weeks the dose can be raised to 3 mg taken twice a day. The further rise of the dose to 4.5 and 6 mg taken twice a day is possible only in well-tolerance of the dose and not sooner than with 2-week intervals.
In the occurrence of negative reactions such as nausea, vomiting, pain in the abdomen, loss of appetite or body mass, worsening of extrapyramidal symptoms such as tremor, it is advised to skip one or two doses. If the adverse effects do not fade away, it is advised to lower the dose back to the previous one if it was well-tolerated or suspend the treatment.
If the treatment had been suspended for more than three days, it is needed to resume it with the dose of 3 mg split into two 1.5 mg intakes. Then dose elevation should be made as described above.
The optimal maintenance dose is selected individually and is usually in the range between 3 and 6 mg taken twice a day.
To achieve the maximum effect, it is recommended to take the highest well-tolerated dose. The maximum recommended daily dosage is 12 mg split into two intakes.
The therapy can continue as long as it provides the beneficial effect. A doctor responsible for the patient must regularly assess the effectiveness of the medication. If after three months of the therapy the symptoms of dementia do not diminish, the treatment must be discontinued.
