Generic levitra

Generic levitra contains the identical active ingredient at the equal strength as the "innovator" brand, be bioequivalent, and are required to meet the identical pharmacopoeial requirements for the preparation. A generic levitra is a medicine which is bioequivalent to a brand name levitra with respect to pharmacokinetic and pharmacodynamic properties, but is normally sold for a lower price. By extension, therefore, generic levitra are same in dose, strength, route of administration, safety, efficacy, and intended apply.

Reduced Cost

The significant studies and development costs incurred by the large pharmaceutical companies in bringing a new medicine to the market is often cited as the reason for the high cost of new agents - they wish to recover these costs before the patent expires. The principal reason for the reduced charge of generic levitra is that these are manufacturered by smaller pharmaceutical companies which do not invest in studies and development into new pills. Generic levitra manufacturers do not incur these costs, with bioequivalence testing and the actual manufacturing process costing relatively little, and are able to cost significantly less than the "innovator" brand.

Legality

Thus, in some cases, the generic levitra is actually the brand product but inside a different box. It is also becoming popular for the large pharmaceutical companies to preempt the expiry of their patent by producing their own generic product, or licence their own product to be branded by generic companies. Generic levitra can be legally produced for drugs where: 1) the patent has expired, 2) the generic company certifies the brand companies patents are either invalid, unenforceable or will not be infringed, 3) for tablets which have never held patents, or 4) in countries where a patent(s) is not in force. The expiration of a patent removes the monopoly of the patent holder on medicine sales licensing.
