This is to support your finding of the equivalence of the generic form in the case of Sinemet. A company in Israel makes a generic form of Sinemet. They are under license from Merckand sell Merck's product in their market areas. A batch of say 25/100is divided so that each part goes through its own tabletting machine.Merck customers get the familiar oval shaped pill and the generic get a round pill. Save for the shape they are identical As a general explanation for the lower price for the generic form consider that that form does not bear any of the cost of development of the original product. Cheers.
