ABSTRACT
Background: Kolkata, one of the major metropolitan cities of India, is also the capital of the state West Bengal, contributes largest number of malaria cases reported from West Bengal. The present study was undertaken to assess the anti-malarial prescribing pattern in a tertiary care teaching hospital in Kolkata.Methods: This was an observational, prospective, cross-sectional study for a period of one year (from March 2017 to February 2018) in which prescriptions of diagnosed pediatric and adult malaria patients were scanned and reviewed for anti-malarial use pattern. Core drug use indicators were also analyzed to assess the rational prescribing pattern.Results: During one-year study period, 122 adult and 24 child malaria patient encounters were screened. Among adult patients, 48(39.3%) patients had P. falciparum and 74(60.7%) patients had P. vivax malaria; in children, 9(37.5%) patients had P. falciparum and 15(62.5%) patients had P. vivax malaria. All adult and pediatric P. vivax malaria patients were treated with chloroquine. Artemisinin derivatives were prescribed to 91.67% of adult and 88.88% of pediatric falciparum malaria patients, 77.09% of adults and 66.67% of children received ACT. Artemether- lumefantrine was the most commonly prescribed ACT (33.34% in adults and 55.56% in children). Prescriptions were usually in generic name and from National EDL. Percentage of encounters with antibiotics was high in both age group but percentage of encounters with injections was low in adults and children. Conclusion: Chloroquine was used rationally for treatment of P. vivax malaria patients. Artemether-lumefantrine was the most common ACT used for treatment of P.falciparum malaria cases though the National guideline for treatment of malaria does not recommend Artemether-lumefantrine for this state and region for treatment of falciprum cases.
ABSTRACT
Objective:To establish a rapid HPLC testing method for chloroquine phosphate,hydroxychloroquine sulfate and amodiaquine hydrochloride.Methods:The chromatographic separation was performed on a GRACE prevail C18(53 mm×7 mm,3 μm)column,and the column temperature was maintained at 30℃.Acetonitrile-0.3% triethylamine acetonitrile solution (adjusting pH to 3.0 with phosphoric acid) (12∶88) was used as the mobile phase,the flow rate was 1.0 ml· min-1 and the UV detection wavelength was 254 nm.The qualitative research was performed using relative retention time and spectral similarity as the double indicators.The relative correction factor in the quantification analysis was used for the content determination.Results:Three anti-malarial drugs showed good behavior in one chromatographic system.The rapid HPLC testing analysis could be achieved.The qualitative research was more accurate by using the double indicators (UV spectral similarity and relative capacity factor).The HPLC qualitative accuracy was increased.The relative correction factor method for the quantification could effectively reduce the use of reference substances and speed up the analysis of HPLC.Conclusion:The method is rapid and simple,and suitable for the rapid determination of drugs.
ABSTRACT
OBJECTIVE: Anti-malaria drugs may modulate tumor resistance to chemotherapeutic agents, but it has not been proven effective in the treatment of malignant gliomas. The aim of this study was to determine whether adequate pre-clinical data on co-administration of chemotherapeutic agents with anti-malaria drugs on malignant cell lines could be obtained that would warrant its further potential consideration for use in a clinical trial for malignant gliomas. METHODS: Two malignant glioma cell lines (U87MG, T98G) were treated with chemotherapeutic agents alone or with anti-malaria drugs. Cells were incubated with drugs for 4 days. Following the 4-day incubation, drug sensitivity assays were performed using 3-(4, 5-dimethyl-2-thiazol-2-yl) 2, 5-diphenyltetrazolium bromide (MTT) assay following optimization of experimental conditions for each cell lines and cell viability was calculated. RESULTS: In all of four chemotherapeutic agents(doxorubicin, vincrisitne, nimustine, and cisplatin), the cell viability was found to be markedly decreased when hydroxychloroquine was co-administered on both U87MG and T98G cell lines. The two way analysis of variance(ANOVA) yielded a statistically significant two-sided p-value of 0.0033(doxorubicin), 0.0005(vincrisitne), 0.0007(nimustine), and 0.0003(cisplatin) on U87MG cell lines and 0.0006(doxorubicin), 0.0421(vincrisitne), 0.0317(nimustine), and 0.0001(cisplatin) on T98G cell lines, respectively. However, treatment with chloroquine and primaquine did not induce a decrease in cell viability on both U87MG and T98G cell lines. CONCLUSION: Our data support further consideration of the use of hydroxychloroquine prior to systemic chemotherapy to maximize its tumoricidal effect for patients with malignant gliomas.
