Atherosclerosis is one of the cardiovascular diseases which often lead to a blood clot. This can cause a heart attack or stroke. This lethal disease seems to be a point of inflexion between generic and brand name drugs. Generic medicines are the class of medicines that are both identical and structurally symmetrical to brand-name drugs. The difference between them lies in the time period for which the patent was held.  Correspondingly, the cardiovascular diseases have shown an evolving trend in the recent years.

A direct relation exists between disease incidence and the time scale or the time period of its existence. Hence the drug patented in the 1970s, has the potential to cure the cardiovascular disease pertaining to that period only. By this way, it has been evident that the brand name drugs prove to be highly efficient during the patent period. When this patent period expires, the local drug manufacturers take over the market in the name of generic drugs. These are in most cases the exact copy of brand name medicine. Apart from the time period and the structural composition, generic medicines' manufacturing also takes place on a wide scale. Generic drugs do not monopolize the market of brand name drugs. This helps to cure highly endemic cardiovascular diseases.

Generic medicines are less costly or in other words economically feasible. This is due to that the fact that brand name drug utilizes heavy R&D to discover a drug, whereas generic drug manufactures just need the relevant information to produce it.
