RESUMO
Background: Cardiovascular disease is very prevalent in India. So, use of cardiovascular drugs is also more. So, it is very important to keep watch on adverse drug reactions. Aim of this study was to assess the pattern of adverse drug reactions (ADRs) reported with cardiovascular drugs in a tertiary care institute.Methods: The study was carried out in medicine department of a tertiary care hospital over a period of one year. Each ADR was analysed for demographic data, causality, relationship between frequency of ADRs and the number of drugs used etc. In statistical analysis Microsoft excel 2013, SPSS software was used.Results: A total of 136 patients, 58 (43%) men and 78 (57%) women, using cardiovascular medications reported ADRs during the entire study period. Total 168 ADRs were reported out of which, Amlodipine (causing headache and edema feet) was the most common drug with 51 (30.3%) ADR’s followed by Enalapril, Aspirin and Isosorbide Dinitrate with 37 (22%), 24 (14.2%), 23 (13.6%) ADRs respectively. Most common ADR was headache (due to amlodipine and Isosorbide di nitrate) affecting 38 (22.62%) cases followed by dry cough 37 (22.02%) cases, edema feet 36 (21.43%), gastritis 24 (14.29%) and 10 (5.95%) of nausea.Conclusions: Monitoring ADRs in patients using cardiovascular drugs is a matter of importance since this class of medicines are mostly used as multidrug therapy and always prone for ADRs.
RESUMO
Background : Cefpodoxime is a semisynthetic third generation cephalosporin analogue with a relatively broader spectrum of antimicrobial activity against gram negative and gram positive organisms. This is attributed to their somewhat increased resistance to degradation by the betalactamase. Cefpodoxime shows good activity against Klebsiella pneumonia, many members of enterobactericeae and almost all strains of Escherichia coli. It is extensively used in human beings against infections caused by susceptible organisms for a prolonged period and even without its judicious indication. Though various researchers have worked on the pharmacokinetic aspects of the drug, its effects on biochemical parameters and spermatozoa activity are scarcely available in literature. Aim : To determine the oral kinetic ( blood and tissue) after single therapeutic dose of cefpodoxime proxetil (20mg/kg oral bid 7 days) in rats of either sex on tissue half life and certain biochemical parameters such as glucose, hemoglobin, protein, ALT, AST and other parameters like tissue residue, sperm count and spermatozoa motility in male rats. Materials and Methods : For kinetic studies,24 Wister rats of either sex, 3 months of age, (180-210 gm) were used.(Group I-IV; n=6) Blood samples collected from each animal of Group IV through heart puncture at 0 hour to serve as predrug control. All the group (I-IV) received cefpodoxime proxetil 20 mg/kg once orally as a single dose. At the end of 1,4,12 and 24 hour post oral administration, GroupI,II,III and IVwere utilized for kinetic studies. Blood samples were collected from each animal and vital organs viz brain, lung, liver, spleen, kidney and heart were dissected out for drug analysis and determination of weight. For biochemical parameters, tissue residue and spermatozoa motility, twelve male rats were randomly divided into Groups A and B (n=6) Group B received cefpodoxime (20mg/kg orally bid 7 days) while Group A served as control. Biochemical parameters [Blood glucose, protein, Aspartate transaminase(AST), Alanine transaminase(ALT)and hemoglobin] were measured at 0 and 7 th day while sperm count (total,live and dead)and mean organ weight (study and control group) and tissue residue of drug were evaluated at the end of treatment. Absorption of cefpodoxime was observed at 2 hour and reached a maximum at 4 hour and persisted in blood till 24 hour. Elimination half life in lung was highest followed by heart, liver, kidney and spleen while t½ k in plasma was very low suggesting more affinity of cefpodoxime for tissues than blood. Results and Conclusion : Blood glucose, protein, AST and ALT activities were not significantly altered but the hemoglobin level and total and live sperm count decreased significantly in the study group compared to the control group. Residual level of cefpodoxime was highest in liver followed by kidney and other study organs. Therefore, the drug should be used in human beings judiciously and further study on human subjects is warranted.
