What if scientists could make better use of technology to predict which drugs will work and pinpoint Now you need to know something about genetic polymorphisms (gene variants) that each individual may carry. Screening for polymorphs is crucial for drug research and development, since the crystal form of the active pharmaceutical ingredient (API) directly correlates with its pharmacokinetic properties. Thus, in the pharmaceutical industry, terahertz technology can be used to identify particular molecules. Q: Is genomic sequencing also part of the picture? Despite its value, accurate and robust analysis of HLA genes has not been possible due to technical challenges related to repeated segments and pseudogenes significantly longer than the typical NGS read length of 150 to 250nt, a combination of extremely polymorphic exons and conserved regions, a haplotype structure, and phasing issues. It is well-known that calcium atorvastatin (ATV), C66H68CaF2N4O10•3H2O, presents polymorphism. The increasing recognition of the importance of polymorphism to the pharmaceutical drug industry has generated a great deal of interest and the field has been evolving rapidly [1]. _ Naturally, polymorphisms in drug-metabolizing enzymes is an important factor that is well known, described, and included in the Medical Compendium designed for physicians; yet, these polymorphisms are not widely taken into consideration targets, including rhodopsin-like G protein– coupled receptors (GPCR), protein kinases, ion channels, proteases, and enzymes, as they have classically been used by the pharmaceutical industry before the use of novel genomic technologies. Considering the amount of substrates it deals with, it is surprising that the pharmaceutical industry probably neglect the enzyme when testing new drugs for bad reactions. To overcome these challenges, the pharmaceutical industry is urgently searching for 2 solutions: “validated” gene targets and biomarkers that predict cardiovascular outcomes in a clinical trial (1,2). Polymorphism of drugs has been the subject of intense interest in the pharmaceutical industry for over forty years. In his painstakingly 275-page decision, the single judge, Justice Manmohan Singh opined that the generic product Erlocip manufactured and sold by Cipla contains polymorphic B variant of Erlotinib hydrochloride as active ingredient and hence do not infringed the compound per se claims of the It is likely that the reasoning of this decision may add yet another disappointment and further dismay for the pharmaceutical companies in enforcing their patents in India . He points out that pioneer companies, those who first create the pharmaceutical product widely claim that patent claims for novel crystal forms is an important component of their intellectual property position, but that it significantly delays the entry of generic versions of drugs once “There are numerous instances where innovator companies have acquired patents on a particular polymorphic form,” says Vure, “which extend beyond the expiry of basic molecule's patent. In addition, longer Terahertz spectral features of the drug ranitidine hydrochloride, polymorphic forms I and II. Every year, the pharmaceutical industry invests billions of dollars in testing drugs that are eventually abandoned because they don't work or cause side effects. €�Omixon has “Thus, pharmaceutical companies can shorten the time to approval and reduce the risk of late-stage failures. Polymorphism – is your pharmaceutical company in good shape? Over the last twenty years, an enormous amount of effort has been expended by both the pharmaceutical industry and academia towards developing more powerful techniques and screening assays to identify the metabolic profiles and enzymes involved in drug These efforts are made in order to avoid latestage drug failure due to such factors as undesirable metabolic instability, toxic metabolites, drug-drug interactions, or polymorphic and saturation metabolism. Even in the US, generic companies successfully launched generic products having different polymorphic forms from the drug substances in the respective RLD (e.g., ranitidine, cefadroxil, terazosin etc.).
