What is the medication called Sinemet and when is it used?
Sinemet is a brand name of a combination medication based on two active substances Levodopa and Carbidopa. These are two substances used together for the therapy of the symptoms of Parkinson’s disease. Unfortunately, they cannot completely cure the disease as it is incurable to date but they can greatly reduce the manifestation of it.
The first substance used in the medication, Levodopa, was discovered in the 1950s. After the discovery that the Parkinson’s disease is associated with the lowered dopamine levels in certain parts of the brain, scientists started working on the medications that could compensate this deficit. After many years of studies, it was discovered that the use of dihydroxyphenylalanine, a natural amino acid, an intermediate product of the biosynthesis of dopamine, norepinephrine, epinephrine, and melanin can be of great help. This is the substance on which Levodopa is based.
Another substance, Carbidopa, has another role, it slows down the peripheral metabolism of the first preparation making it possible for the larger dose of the substance penetrate the blood-brain barrier and provide the more potent effect.
Your doctor can tell you to buy Sinemet if you are diagnosed with Parkinson’s disease or syndrome.
What is the medication marketed as Generic Sinemet? Why is it cheaper?
Generic medications with the same active substances as the branded preparations have the same effect and indications for use. They are no way inferior to the branded medications but cost much cheaper. Generics are started to be manufactured when the exclusive patent of the drug creator’s expires so their makers do not pay for the research but rather enjoy someone else’s discoveries. This practice is used to make the medications affordable for people from the developing countries while the majority of medical preparations are discovered or synthesized in the developed countries where all medications are quite expensive. Besides, the owners of the well-known and advertised brand medications set the high prices even if they already returned the investment in the research because they are able to do so for the countries where people have the possibility to pay more money for drugs. But if you don’t have enough money to use the branded medication or simply do not see the point of paying more money for the recognized name on the package of pills, you can buy Generic Sinemet instead. However, make sure to read this medication guide carefully and consult your doctor before you start using the pills even though you can get them without a prescription from this webpage.

- The combination with anesthetics can cause arrhythmia.
- Anticholinergics can act in synergy with the medication for the reduction of tremor but in some cases, they can only worsen the uncontrolled movements. In high doses, they can also lower the positive effect of Levodopa through the prevention of its absorption.
- The therapeutic efficiency of Levodopa can be lowered also by Phenothiazines, benzodiazepines, isoniazid, butyrophenones, Phenytoin, iron medications, anticonvulsants, and papaverine.
The diet high in protein can cause the lower the amount of the active substance that is active in the body.
The combined therapy with selegiline can cause the occurrence of pronounced orthostatic hypotension.
Sympathomimetic medications can enhance the cardiovascular adverse effects of Levodopa.
Metoclopramide increases the level of Levodopa in the blood plasma.
The bioavailability of Levodopa can be increased in the combination of the preparation with inhibitors of catechol-o-methyltransferase (e.g. tolcapone, entacapone).
What adverse reactions can you expect from the use of Sinemet?
When you buy Generic Carbidopa + Levodopa, you should be ready that the medication can be unsuitable for you because it would cause adverse reactions.
The negative symptoms caused by the medication are commonly associated with the neuropharmacological activity of dopamine. Usually, they disappear with the reduction of the daily dosage. The most common adverse effects are dyskinesia (abnormal sudden involuntary movements in different muscle groups). The spasms of muscles and blepharospasm (the twitch of the eyelid) indicate that the daily dosages must be lowered.
The other serious adverse reactions can be mental state changes, including paranoid thinking and psychosis, depression with or without suicidal tendencies. Some cases of pathologically increased libido and hypersexuality were reported, but they also tend to fade away in the reduction of the dosages or the withdrawal of the drug. In any case, if you start suffering from any adverse reactions from the medication use even from the effects not listed here, inform your doctor immediately.
