Generic drugs are non-branded products functioning the same as reference-listed drugs and are of the same attributes. They also have the same administration and dosage; they are generally cheaper because they do not take less time, research, and development to produce.
Biosimilars are medical products similar to original versions of the product manufactured by a different entity. They are approved and can often be produced and sold upon expiration of the patent of the original product.
Biosimilars are different from generic drugs primarily on the basis of contents. Generic drugs have an identical composition as the original drug of reference. Biosimilars, on the other hand, are similar to their reference drugs in biologics but not identical.
