In Ayurved it is compared with Darunak falling under the category of kshudrarogadhikar and is caused due to the vitiation of vaat and kapha. Traditionally the treatment comprises of application of oil, steaming, applying packs, washing of hair etc. According to modern science dandruff is a non-treatable disease condition which is prevented by use of anti-dandruff shampoos, creams and hair masks. The available products are expensive and results are not very satisfactory and recurrence is common. Currently treatment available for dandruff is found to be expensive with unsatisfactory results in terms of recurrence of symptoms. \u0000Aim and objective: Pharmaceutical development, standardization and clinical evaluation of efficacy of a polyherbal Hair pack and Hair gel in dandruff  control \u0000Materials and methods: Hair pack will be made with selected drugs like Amalki, Bibhitaki, Haritaki, Japa, Yashtimadhu, Musta, Brahmi and it will be converted into gel form. Analytical study for standardization of powder and gel dosage form will be done. Clinical evaluation of both dosage forms for efficacy will be done. \u0000Observations and results: Observation will be done on the basis of photographic evaluation of the condition of pre and post severity of symptoms and duration of recurrence time of dandruff will be noted. Results will be drawn on the basis of observations and applying suitable tests. It will be noted and presented in form of table, charts, graphs etc. \u0000Conclusion: Currently available treatment for dandruff does not provide complete remission of symptoms for long duration and it is very expensive too. Thus the newly designed herbal formulation is aimed to provide significant result in controlling dandruff and its associated symptoms and modified dosage i.e. gel will overcome the limitation of powder and provide a cost effective cosmetic product in controlling dandruff.","PeriodicalId":16706,"journal":{"name":"Journal of Pharmaceutical Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41418145","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}

It is rich source of calcium & minerals. As per text it can be converted into two forms which are bhasma (calcinated ash) and pishti (powdered form without agni).These forms may have different rate of absorption. This needs to be studied. Aim: To study Pharmaceutico-analytical study of Muktashukti pishti & Muktashukti bhasma and comparative evaluation of their relative oral bioavailability. Materials and methods: The two formulations will be prepared from shukti (oyster). By triturating with Gulabjala Muktashukti pishti will be prepared and by traditional puta method Muktashukti bhasma will be prepared. The prepared formulations will be assessed for Bhasma Pariksha mentioned in Ayurveda.

The study was conducted for a period of six months, from June 2019 to November 2019. Methodology: A pre-designed data collection form was used to collect the data from the study participants. The required data was obtained from the patient case sheet, lab reports, treatment charts, daily nursing notes, daily physician notes, and direct patient interviews. The global trigger tool developed by IHI was used for the rapid review of inpatient medical records and to generate clues for the identification of ADEs. Descriptive statistics were used to represent the findings of demographics, clinical characteristics, ADE profiles, IHI triggers, and clinical alterations. ADE incidence was shown in a measure of ADE per 1000 patient days. IHI global trigger tool performance in detecting ADE was measured by sensitivity, specificity, positive predictive value, and negative predictive value. Results: A total of 192 patients were enrolled in the study. Among them, 225 triggers and 123 ADEs were detected. The incidence of ADEs in the inpatients estimated by the IHI method was estimated as; 20.2 ADEs per 1000 patient days,64.0ADEs per 100 admissions, 56.2percent of admissions with ADE. Majority of ADEs are shown possible relationship with drug (60; 48.7%), level-2 severity (49; 39.8%), and not preventable (52; 42.2%). Most IHI global triggers showed high sensitivity, specificity, positive predictive value, and negative predictive value for detecting ADEs. Conclusion: The study shows that most of the triggers in the IHI Trigger tool have shown good accuracy in identifying ADEs. Thus, using the IHI Trigger Tool to identify ADEs can help to improve patient safety. Therefore, the study recommends incorporating IHI global trigger tool in routine, conventional ADE screening techniques to improve the detection rate and promote drug safety.","PeriodicalId":16706,"journal":{"name":"Journal of Pharmaceutical Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47045941","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}
