Pharmaceutical companies invest massively in research and development, production and marketing of new medicines. Legally, a patent lasts for 20 years, but for pharmaceutical patents it is about 16-18 years, as they must pass FDA regulations before they can be marketed. After the patent expires, the generic manufacturer produces a generic version of the same drug compound stability profile and sells it in the market at a much lower price. In order to remain competitive, innovative companies want to extend the life of medicines. A particular drug is extended to last longer. A medicine is thus not protected by any specific patent, but is covered by several patents, including patent blocking. Patents don’t protect substances, they protect “inventions”.
It is important for patent practitioners involved in pharmaceutical research to better understand the various pharmaceutical patents and the ways in which pharmaceutical patents can be extended. Medical patents fall into the following categories:
- Product form
- Withdrawal from medication
- Physical shape
- Particle size
A composition patent describes one or more active ingredients (known or novel) and pharmaceutically acceptable combinations or combinations of solvents, buffers, excipients, binders, disintegrates and lubricants. Selected combinations of molecules and their innovative functions have been used in the discovery of these patents.
In India, an active ingredient (known or new) in a new drug product cannot be patented as there is no synergy between the ingredients. An active component and an inactive carrier.
A formulation patent refers to the manufacture of a particular formulation in a specific form for improved effect, appearance or release.
Mode of release: any new or previously known dosage form of the drug or formulation of the drug, preferably by active release of the drug. The same active ingredient can be formulated in different forms, such as tablets, capsules or for parenteral administration in aqueous solution. For example, anti-inflammatory creams that contain A to control diabetes are different from pills that contain “A”. It is a new cream because it was not developed in this form before “A” and would have been invented if “A” had not been used in its proper form before. “It has been
A Brief History of Prescription Pharmacy
Although compounding may seem like a relatively new trend with the popularity of specialty drugs, compounding has long been rooted in traditional drug administration.
Thousands of years ago, hunter-gatherers relied primarily on the medicinal properties of natural ingredients, such as animals, plants and fungi. They knew that in most cases, if an ingredient had similar medicinal properties, it was possible to combine several ingredients to create multi-effect products. While some of the “medicines” he created were effective, many had no proven medicinal properties, and some even worsened certain health problems! Primary care physicians and physicians struggled to effectively treat the disease because they misunderstood the cause. For many pharmacists, drug development used to be a process of trial and error. The first commercial pharmacy is believed to have opened in Baghdad in the eighth century, and Islamic pharmacists were influential in developing better methods of making medicines.
The development of pharmaceutical products
Has not only led to the preclinical formulation developmentof sophisticated drugs. Although early chemists were often motivated by a desire to create commercial dyes, perfumes, or cosmetics, many were the result of accidental preparations that functioned as successful drugs. Alchemists seeking to transmute base metals into gold or create the emerald of life may also have contributed to the development of medicinal chemistry through experimental methods.
During the 20th century, pharmacists began to experiment more and more with chemical compounds and synthetic ingredients to make drugs. To some extent they were able to produce crude medicine. As doctors learned more about the nature of the disease and the virus, they were able to increase their knowledge in order to successfully treat the disease. Chemists were then able to isolate and isolate the active components of crude drugs and use these components to create more effective drugs.
