Generic medicines are generally copies of brand-name drugs. They include the same chemical substance as the brand drug. When a drug comes with a new active
ingredient, it is originally protected by chemical patents. Generic versions of these drugs are only allowed for sale after the patents on the brand drug expire. Generic Medicines have the same dosage, intended use, effects, and side effects compared to brand drugs. In other words, these drugs have the same pharmacological effects as brand-name drugs.
Generic drugs are substantially cheaper than brand-name drugs.
However, these drugs are safe and effective as brand-name drugs and approved by FDA (U.S. Food and Drug Administration).The ED generic medicines are cheaper because the manufacturers have not many expenses as compared to a new drug. For example, they do not have the expenses of developing and marketing a new drug. Therefore, generic drugs are easily available and affordable as compared to brand drugs.
