Amifsotine, a hydrophilic and extremely short half-life cytoprotective agent, was loaded based on chelating complex micelles (CCM) in order to provide the protection from radiation exposure. The preparation of amifostine-loaded CCM (CCM-Ami) was simply mixing ferrous chloride, poly(ethylene glycol)-block-poly (glutamic acid) (PEG-b-PGA) and amifostine in an aqueous solution without using any organic solvent. The resulting CCM-Ami monodispersed with a mean particle size 25 nm and showed a slow release behavior as compared to amifostine. Furthermore, CCM-Ami pretreatment improved survival rates and median survival in C57BL/6 mice than did treatment with a corresponding dose of amifostine. These results point to a potential use of CCM as a novel drug carrier. Drug molecules that may act as ligands can be considered delivering by this platform technology.","PeriodicalId":16958,"journal":{"name":"Journal of Pharmacovigilance","volume":"238 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79421242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But when they no longer needed their disposal become necessary because drug is a chemical and once it expires it will become a toxic agent. The people may have expired drugs, unused or unwanted medicines which may occur as a result of non-adherence, excessive storage of OTC medication or disuse of drugs. The USFDA initiated ‘drug take back programme’ to prevent the entry of these medication into environment. But in India drug take back programmer is not functional. The country is now facing the numerous problems due to improper drug disposal methods such as burning, flushing into toilet and throwing somewhere or into waste-basket which may lead to environmental contamination and pollution, contamination of water supplies and other local sources used by community and wildlife which will results in serious environmental and health hazards like toxicity, accidental poisoning and drug abuse, development of drug resistance problems and even death. Since the drug take back programme is not functional in the developing countries like India several cases of toxicity and accidental exposure are seen day by day. So an online survey was conducted in general population in order to check the knowledge of people regarding safe drug disposal system. From the data, 73% of 214 people are not aware of safe and effective disposal of drugs without causing any harmful effect to nature and public.","PeriodicalId":16958,"journal":{"name":"Journal of Pharmacovigilance","volume":"9 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79095287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Patients with head and neck cancer (148 patients) were treated by three–dimensional radiotherapy in the Center of Oncology and Nuclear Medicine, Military Medical 103 Hospital from February 2014 to April 2016. All patients underwent an ear examination (otoscopy), audiometry, and tympanometry test. Those who developed otitis media with effusion and tympanosclerosis were then treated by tympanostomy or myringotomy. Results: The most common complication after the radiotherapy was found to be Eustachian tube dysfunction, especially otitis media with effusion and tympanosclerosis. Thus, carefully examining and closely monitoring need to be performed to detect patients with secondary middle-ear damages, to successfully cure post-radiotherapy otitis media with effusion, and to minimize possible injury to the middle ear and Eustachian tube. Also, tympanostomy and myringotomy were reported to be the preferable treatments due to their simplicity, high quality, and patients’ compliance. Conclusion: Eustachian tube dysfunction after radiotherapy treatment was the cause for otitis media with effusion and tympanosclerosis. Furthermore, tympanostomy and grommet insertion were convenient, efficient, and desirable treatments for secondary middle-ear damages in patients with head and neck cancer.","PeriodicalId":16958,"journal":{"name":"Journal of Pharmacovigilance","volume":"46 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84065326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: This study included 74 MG patients treated with tacrolimus (n=65) or CyA (n=22). Genomic DNA was extracted and amplified with specific primers, and CYP3A5 alleles were confirmed by direct sequencing of PCR products on an automated AB13100 DNA sequencer. We measured blood trough level (C0) of tacrolimus and CyA. Clinical disabilities were evaluated with the MG-ADL scale. Results: For tacrolimus C0, the CYP3A5*3/*3 genotype was associated with higher levels than the CYP3A5*1/*3 genotypes (7.1 ng/ml versus 2.9 ng/ml; P<0.0001) and CYP3A*1/*1 (7.1 ng/ml versus 1.3 ng/ml; P<0.0004). The improvement in the mean MG-ADL scores tended to be better in MG patients with the CYP3A5*3/*3 or CYP3A5*1/*3 than those with CYP3A5*1/*1. For the CyA concentrations, CYP3A5 genotypes did not have significant effects. Conclusion: In MG patients, CYP3A5 polymorphism significantly affects serum levels of tacrolimus and thereby treatment effects, but not those of CyA. The maintenance dose of tacrolimus should be determined considering CYP3A5 polymorphism.","PeriodicalId":16958,"journal":{"name":"Journal of Pharmacovigilance","volume":"8 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84195231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pharmacovigilance (PV) is a scientific activity which keeps constant watch on the drug throughout its life cycle. In India, Indian Pharmacopoeia Commission (IPC) and National Coordination Committee (NCC) through the Central Drug Standard Control Organization (CDSCO) cordially regulate the PV activity. To build a potential PV system in India, Pharmacovilance Program of India (PvPI) have been proposed and implemented by the Indian government in 2010. The accurate detection and reporting of ADR is a heart of this system. Hence various regional, zonal and peripheral centres have been proposed for the smooth and effective reporting of ADR. Anyone can report ADR by filling the suspect ADR reporting form available online or offline to the nearest centre in suitable language. Considering Indian geographical distribution, huge population and mobile network connectivity, a toll free number and the mobile app is also provided for timely and effective reporting of ADR. The reported ADRs are collected and processed at the centres in Vigi-flow software. These centres detect signal which are reported to CDSCO and World Health Organisation (WHO) for the further regulatory action. CDSCO-WHO communicates their decision through a suitable media for the betterment of public health.","PeriodicalId":16958,"journal":{"name":"Journal of Pharmacovigilance","volume":"28 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84513543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prospective study of active pharmacovigilance during six months was performed. Each patient was followed for two months. The French method was used to determine the causality assessment.Results: 86 inpatients or outpatients were enrolled. 65.12% experienced a side event (SE). Among them, 22.09% had insomnia, 17.44%, drowsiness; 5.81%, dyskinesia; 4.65%, an appetite increase and 4.65%, headaches. The percentages of patients with 1, 2, 3, 4 and 5 side events were 39.28%, 41.07%, 8.92%, 7.14% and 3.57% of the 65.12% respectively. The average number of side events per patient was similar in hospitalized patients and in those treated ambulatory (1.97 vs. 1.92). The causality assessment of the side events to the drugs prescribed to each patient is predominantly doubtful (52.29%). It is likely in 44.95%, very likely in only 1.83% of the cases and plausible in 0.92% of the patients. All SEs occurred during the first month, most during the first week. The management of adverse drugs reactions led to drug doses reduction only in 23% of the cases while responsible drugs were stopped in 5.77% of the cases.Conclusion: The relatively high frequency of typical antipsychotics of use and low daily dose of benzodiazepine among our patients merit further investigation and systematic efficacy and safety monitoring. Typical antipsychotics should be made more available and monotherapies should be encouraged. The pharmacovigilance should be developed in the country by installing a National Center and by training health professionals.","PeriodicalId":16958,"journal":{"name":"Journal of Pharmacovigilance","volume":"32 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2017-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87333710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods/Statistical analysis: Both raw and modified clay samples were used as catalysts under reaction conditions; 5wt% of catalyst to oil, molar ratio of methanol to oil of 27:1, 4 h reaction time and temperature of 67°C. The unmodified and modified clay samples were characterized by, thermogravimetric analysis-differential thermogravimetric (TGA-DTG), Brunauer-Emmett-Teller (BET), inductively coupled plasma-emission spectroscopy (ICP-ES), atomic absorption spectroscopy (AAS), X-ray powder diffraction (XRD), Fourier transform infra-red (FTIR) and field electron scanning emission microscopy (FESEM). Finding: Application/Improvement: BET analysis showed increase in specific surface area for both Jourdiqua and Jabbalmarra clays. Elemental analysis by ICP-ES showed decrease content in elements of Al, Mg, Na and K for both clays, due to the acid leaching.
