A review of novelistic method used for formation pharmaceutical Cocrystals and Marketed available formulation

Pharmaceutical cocrystallization is a potential method for improving the solubility of BCS Classes II & IV
drugs that are poorly soluble. The majority of scientists are ignorant of this method and the advantages of
cocrystallization on the stability and pace of drug dissolution. Approach: Evidence was systematically and
concisely gathered from a variety of publications using Medline, Pubmed, Embase, Scopus, Google Scholar,
and Web of Science. This study covers cocrystallization technologies, goods that have been sold using this
approach, and issues related to these procedures. Finding: The novelistic or current techniques used for the
production of cocrystals are hot melt extrusion, spray evaporation, super critical fluid dynamic technology and
laser irradiation which is the most trending and effective method for cocrystal formation. This paper also
includes the various in-vitro evaluation parameters that are carried out for evaluating the cocrystals and their
drug release. It also defines the reasons for the interest of cocrystals by a researcher and pharmaceutical
industries, various novelistic and traditional method of manufacturing of pharmaceutical cocrystal.
Conclusion: Pharmaceutical crystals are now seen as a significant medicinal or research need. This is evident
in the numerous reviews and research papers that have been published in different publications over the
previous ten years. Various pharmaceutical businesses have been enforcing patents internationally in recent
years. These businesses are expanding quickly as a result of the legislation and intellectual property
connection. Pharmaceutical crystals are a crucial and effective method for increasing a drug's bioavailability,
stability, and melting point.

药物共结晶（Pharmaceutical cocrystallization）是改善难溶性生物药剂学分类系统（Biopharmaceutics Classification System, BCS）II类与IV类药物溶解度的潜在方法。当前多数科研人员对该方法，以及共结晶在药物稳定性与溶出速率方面的优势仍知之甚少。研究方法：本研究通过Medline、Pubmed、Embase、Scopus、Google Scholar及Web of Science等多个学术数据库，系统且简洁地收集了相关研究证据。本文涵盖了共结晶技术、采用该技术获批上市的药品，以及该工艺相关的各类问题。研究结果：当前用于制备共晶的新型或主流技术包括热熔挤出（hot melt extrusion）、喷雾蒸发（spray evaporation）、超临界流体动力学技术（super critical fluid dynamic technology）与激光辐照（laser irradiation），其中激光辐照是当下最热门且高效的共晶制备方法。本文还涵盖了用于评估共晶及其药物释放行为的各类体外评价参数，阐明了科研人员与制药行业关注共晶的动因，以及制备药物共晶的各类新型与传统工艺方法。结论：药物共晶现已成为重要的医药研发刚需。近十年来，各类学术期刊发表的大量综述与研究论文均可印证这一点。近年来，多家制药企业已在全球范围内布局共晶相关专利。依托相关立法与知识产权保护体系，这类企业正实现快速扩张。药物共晶是提升药物生物利用度、稳定性与熔点的关键且高效的技术手段。
