Fourier transform infrared spectroscopy (FTIR) and (DSC) Differential scanning calorimetry were used to test the compatibility of the drug-polymer. The diverse formulations were prepared and tested using Design Expert® ver 8.0.1 software to optimize the experiment technique and employ the response surface. The tissue compatibility of the test verified the existence of non-irritants in the established formulation. All preparations contained the drug content from approximately 97.98 to 99.88%. Viscosities are ideal for injection in the optimized formulation (1,55 percent w/w in water). The optimized formula was monitored, and up to 156hours, it was found to be 95.7%. The result was that ISFI can effectively monitor and control the delivery of several powerful drug products.","PeriodicalId":8332,"journal":{"name":"Annales pharmaceutiques francaises","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142456832","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}

Investigations for new antimalarial drugs from traditional medicine have proven to be more effective and less expensive. The medicinal plants that have been used for treatment of malaria, generally known as types of fevers in traditional medicine, can be suitable candidates for evaluating antimalarial effects. The aim of the present study was to evaluate the in-vitro mechanism of antimalarial action of selected medicinal plants by inhibition test of heme detoxification (ITHD).Material and methods: The methanol extract and fractions were prepared through maceration of the dry powdered plants. The ITHD method was carried in 96-wells plate and the percentage of heme polymerization inhibition was determined. The cytotoxicity of the effective plants were examined on MDBK cell line by MTT assay. Bioassay guided fractionation was performed exposing to size exclusion column chromatography and liquid-liquid fractionation and was assayed by the ITHD method for the sample with the least IC50 value and lowest cytotoxic effect.Results: The methanol fraction of Viola odorata whole plant showed the most considerable results among the tested plants with IC50 171.8 μg.mL-1 beside the lowest cytotoxic effects. This fraction by the bioassay guided fractionation led to fraction SB2 and this fraction demonstrated the most effective result with lowest IC50 = 14.8 ± 3µg.mL-1 in ITHD assay.Conclusion: Regarding the results of the present study and the traditional use of V. odorata for overcoming fever in Iranian traditional medicine, the final fraction of the plant could be proper candidate for further phytochemical and antimalarial studies.","PeriodicalId":8332,"journal":{"name":"Annales pharmaceutiques francaises","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142456831","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}

The objective is to conduct a risk analysis to evaluate the impact of various actions taken. The lung transplantation team was convened to carry out a failure mode effect analysis. The process was divided into stages where different risks were identified. The risk priority number (RPN) (severity, frequency, detectability) and risk level of criticality (frequency, severity) were established before implementation of actions (before 2009) and then after (in 2022) to classify risks according to four levels of criticality. The implemented actions included the establishment of a quality assurance process, computerization of monitoring, and double analysis by a physician/pharmacist pair. Thirty-two risks were identified during the four stages of the process: biological sampling (n=13), reception (n=3), analysis and treatment of levels (n=5), transmission of information/prescriptions to the patient (n=11). The total raw RPN (before 2009) was 839, with 12 major risks. The current total RPN (in 2022) was 452 (a decrease of 46.1%), with 7 major risks identified. The analysis enabled the objective evaluation of the effectiveness of the actions taken. The most secure stage of the process is the reception of residual level results. Efforts should focus on empowering and involving patients, as well as engaging local stakeholders in collaboration with the specialized transplantation team.","PeriodicalId":8332,"journal":{"name":"Annales pharmaceutiques francaises","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142364229","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}

The market for natural gums like hupu gum (gum kondagogu) is growing globally, driven by increasing consumer preference for natural and sustainable ingredients. This review covers botanical origin, geographical distribution, chemical constituents, identification tests, toxicology studies and potential applications of hupu gum in novel drug delivery systems. Emphasis is placed on its traditional uses in indigenous medicine and current research findings and patents that highlight its emulsifying, stabilizing, film forming, and thickening properties. Hupu gum is a tree exudate from Cochlospermum religiosum belonging to the family Bixaceae. It is traditionally used for various medicinal and industrial purposes as it has a unique chemical composition and physical properties. Moreover, the current research and use of hupu gum as a biopolymer in the formulation and stabilization of nanoparticles (NP) is expanding the application spectrum of hupu gum.

These therapeutic virtues are mainly due to the plant essential oil. The chemical components of this oil were identified using GC-MS, and the variability in these components' levels was examined in nine samples that were taken at different times from two locations in Algeria's northern Sahara. The contents of the essential oil were found to consist of eight components, varying in concentrations: beta-thujone (46.80%), 1-Methyl-2-(1' methylethenyl) -3'- ethenylcyclopropylmethanol (14.59%), 1,8-Cineole (12.63%), limonen-10-ol (9.47%), 1(7),3,8 o Menthatriene (3.45%), and (-)-Camphor (2.11%). Toxicity studies were conducted in order to assess the safety of the essential oil, namely: LD50 estimation and biochemical blood parameters evaluation. The results showed an LD 50 of 507.5mg/kg close to the LD50 of Beta-thujone (442mg/kg): the main component of the essential oil, making it accountable for the major toxicity. The apparition of seizures as toxic manifestations for higher concentrations confirmed that. The essential oil of Brocchia was noted to be classified as slightly, weakly toxic, and the Beta-thujone contents showed to be within the regulatory accepted values, which makes the use of Brocchia safe within the indicated standards.","PeriodicalId":8332,"journal":{"name":"Annales pharmaceutiques francaises","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142279855","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}
