Generic Symmetrel (Amantadine 100 mg) guide:
What is the medication called Generic Symmetrel?
Symmetrel is a brand name of an antiviral medication used to treat some forms of flu. It is also used for Parkinsonism. However, it is not the only drug with this composition suitable for both conditions. The active substance of the medicine is Amantadine which is known since 1967. Since the exclusive patent for the preparation production has expired long ago, the same preparation can be manufactured by different pharmaceutical companies. Collectively, these drugs are called Generics of Symmetrel. Although this is not a registered name and all of the medications have their own registered names, when you want to purchase the medication cheaper than the branded drug, you can simply tell the pharmacist that you want to buy Generic Symmetrel, and he or she will understand what you want. This collective name was introduced to help people find the medication they need at a cheaper price because it is made by another manufacturer without knowing all of the registered names of the medication. This is an initiative of the World Health Organization that even promotes generics as they make essential medications affordable for more people.
Is Generic Symmetrel inferior to the branded medicine because it is cheaper?
You may have doubts about the efficiency of the generic because of its lower price but you should not worry – all generics are made using the same formula and substances that are used for the branded preparations. Moreover, they never appear on the market if their identity to the branded medication wasn’t proved. So, why they are cheaper then? The thing is that their manufacturers do not develop new formulas but wait till the exclusive patent of the drug developer is no longer valid and then start producing their preparations. Generic drug makers also do not advertise their medications or promote them through rewarding to the doctors for prescription of namely their trademark medications as the manufacturers of branded medicines do. Therefore, you don’t need to worry as the quality of the medication doesn’t depend on the manufacturer. You can order Generic Symmetrel and as long as the active substance of the medication is Amantadine, you can rest assured that you are using the right medication and can follow the instructions for the best effect.
