RESUMEN

The advent of HIV-Integrase inhibitors (IN) has marked a significant impact on the lives of HIV patients. Since the launch of the first anti retro-viral drug "Azidothymidine" to the recent advances of IN inhibitors, about 27.4 million people benefit by antiretroviral therapy (ART). The path had been challenging due to many crossroads, leading to the discovery of newer targets. One such recent ART target is Integrase. Use of Integrase inhibitors has surpassed the usage of all other ART owing to a strong barrier to resistance and have been reported to be the first-line therapy. Raltegravir, Elvitegravir, Dolutegravir and Bictegravir are US FDA approved IN inhibitors. The high usage of ART created an opportunity to study various analytical techniques for IN inhibitors. Hitherto, no review encompassing all IN inhibitors is presented. Herein, this review describes the analytical techniques employed for IN inhibitors estimation and quantification reported in the literature and official compendia. Literature suggests that most studies focus on LC-MS/MS and HPLC methods for drug estimation, and few reports suggest spectrophotometric, spectrofluorimetric and electrochemical methods. Furthermore, the review presents the techniques that describe the quantification of integrase drugs in various matrices. Although, antiretroviral drugs are extensively used but data suggests that limited studies have been conducted for determination of impurity profile and stability. This therefore, presents a scope to detect and validate impurities in order to meet ICH guidelines for their limits and further to improve the quality and safety of antiretroviral drugs.

RESUMEN

Radiopharmaceutical preparations are the important pharmaceutical dosage forms used for the diagnosis and therapeutic purposes. Various pharmacopoeias are having methods for the quality control of these preparations in the form of monographs. Indian Pharmacopoeia (IP) also included these monographs in IP 2014 first time with the help of an experts' group on radiopharmaceutical, drawing expertise from elite stakeholder institutions and the core team of Indian Pharmacopoeia Commission. Since then, these standards are regularly updated through the IP addendum and bringing out new edition of IP. IP is a book of official methods as per Drugs and Cosmetic Act, 1940. These standards can be used in government laboratories, private laboratories, or academia in India and abroad. This review provides an overview of the journey of radiopharmaceuticals' standard setting in IP. A comprehensive comparative information of regulatory perspectives of radiopharmaceuticals in different jurisdictions such as the US, EU, and India is also presented.

RESUMEN

BACKGROUND: The National Coordination Centre-Pharmacovigilance Programme of India (NCC-PvPI), Indian Pharmacopoeia Commission works under the aegis of Ministry of Health and Family Welfare, Government of India. It promotes patient safety in India and also supports postmarketing surveillance programs. Currently, almost hundred thousand case reports are submitted to NCC-PvPI each year through its 250 ADR Monitoring Centers (AMCs) located across India, and India is the one of the top ten contributor countries under WHO-Uppsala Monitoring Centre since 2012 and start issuing drug safety alerts from March 2016. AIM: This study aims to highlight the drug safety alerts issued by NCC-PvPI from March 2016 to June 2017 and urgent need for further monitoring by adopting targeted spontaneous reporting (TSR) methodology at AMCs and its impact on the NCC's drug safety database, i.e., VigiFlow in India. METHODOLOGY: A retrospective analysis was done for the reported unlisted ADRs by various AMCs to PvPI through VigiFlow, i.e., individual case safety report (ICSR) management system at NCC, where these unlisted drug-ADR combinations considered and issued as drug safety alerts for further reporting these to NCC, if any detected at healthcare settings during routine clinical practice by healthcare professionals. RESULTS: From July 2011 to June 2017, NCC-PvPI was collated 250,787 ICSRs and contributed to WHO international drug safety database, i.e., VigiBase, from these ICSRs; NCC-PvPI was issued 56 drug safety alerts from March 2016 to June 2017. CONCLUSION: In India, spontaneous reporting of ADRs existed since 1998 under passive surveillance method, but there is an urgent need to initiate TSR, which is a complementary method to spontaneous reporting on these drug safety alerts for further regulatory action by Central Drugs Standard Control Organization.

RESUMEN

OBJECTIVE: To study the case series for intussusception associated with the vaccination of rotavirus vaccine in children. METHODS: The study of spontaneous adverse event monitoring such as intussusception due to rotavirus vaccine was carried out from the year 2011 through 2015. The individual case safety reports (ICSRs) of this event were collated, assessed and recorded as per the requirement of Suspected Adverse Drug Reactions Reporting form of Pharmacovigilance Programme of India (PvPI). RESULTS: In the present study, 10 ICSRs of intussussception due to rotavirus vaccine were reported to PvPI. Of which 3 ICSRs were found to be causal relationship with rotavirus vaccine, as evidenced by the adequate information provided in ICSRs. CONCLUSIONS: Since intussusception, the emerging safety as one of the important safety concern, healthcare professionals are advised to monitor and report to the concerned authority for appropriate action.

RESUMEN

Mammalian spermiogenesis is of considerable biological interest especially due to the unique chromatin remodeling events that take place during spermatid maturation. Here, we have studied the expression of chromatin remodeling factors in different spermatogenic stages and narrowed it down to bromodomain, testis-specific (Brdt) as a key molecule participating in chromatin remodeling during rat spermiogenesis. Our immunocytochemistry experiments reveal that Brdt colocalizes with acetylated H4 in elongating spermatids. Remodeling assays showed an acetylation-dependent but ATP-independent chromatin reorganization property of Brdt in haploid round spermatids. Furthermore, Brdt interacts with Smarce1, a member of the SWI/SNF family. We have studied the genomic organization of smarce1 and identified that it has two splice variants expressed during spermatogenesis. The N terminus of Brdt is involved in the recognition of Smarce1 as well as in the reorganization of hyperacetylated round spermatid chromatin. Interestingly, the interaction between Smarce1 and Brdt increases dramatically upon histone hyperacetylation both in vitro and in vivo. Thus, our results indicate this interaction to be a vital step in the chromatin remodeling process during mammalian spermiogenesis.
