Generic versus innovator: Analysis of the pharmaceutical qualities of paracetamol and ibuprofen tablets in the Nigerian market
(2009) Okunlola, A.; Adegoke, O. A.; Odeku, O. A.
The physicochemical equivalence of twenty-two brands of paracetamol and nine brands of ibuprofen tablets sourced from retail Pharmacy outlets in the Nigerian market to their respective innovator brands were investigated. The uniformity of weight, friability, crushing strength, disintegration and dissolution times and assay of active paracetamol ingredient were used as assessment parameters. All the brands of paracetamol and ibuprofen tablets complied with the official specifications for uniformity of weight. However, five brands of paracetamol failed the friability test, one brand of paracetamol and two brands of ibuprofen failed the disintegration test and three brands of paracetamol and four brands of ibuprofen failed the assay of active ingredients. The study shows that not all the brands of paracetamol and ibuprofen tablets are physico-chemically equivalent to their innovator brands. There is therefore the need for constant market surveillance to ascertain their compliance with official standards and equivalence to the innovator products.
Multidrug resistant and extended-spectrum beta-lactamase (ESBL) producing proteus mirabilis from tertiary hospitals in four states in Southwest Nigeria
(Nigeria Association of Pharmacists in Academia (NAPA), 2015) Alabi, O. S.; Adeleke, O. E.; Adegoke, O. A.; Gbadeyan, O. F.; Ejilude, O.
Background: Multidrug resistant (MDR) and extended-spectrum beta-lactamase (ESBL) producing Gram-negative bacteria pose great threat to antibiotic treatment of life threatening infections worldwide. Objectives: This study investigated the occurrence and distribution of MDR and ESBL producing Proteus mirabilis among clinical isolates collected from tertiary hospitals in four states in Southwest Nigeria. Materials and Methods: One hundred and eight (108) none-duplicated P. mirabilis collected from microbiology units of tertiary hospitals in four states in Southwest Nigeria namely; Oyo, Osun, Ogun and Lagos state, after authentication with standard bacteriological method, were subjected to antibiotic susceptibility test against ten selected antibiotics using disc-diffusion method. Presumptive production of ESBL was determined by double disc synergy test among isolates with MDR phenotype that showed resistance to any of the third generation cephalosporin antibiotics. Results: Of the 108 clinical isolates of P. mirabilis collected from Oyo (39.8%), Osun (25.9%), Ogun (21.3%) and Lagos (13%) states, 60 (55.6%) showed MDR phenotype. Among the 60 MDR isolates collected in Oyo (50%), Lagos (10%), Ogun (21.7%) and Osun (18.3%), 66.7%, 66.7%, 30.8% and 9.1% of the isolates produced ESBL, respectively. Conclusion: This study recorded the occurrence of ESBL and MDR P. mirabilis in all the four states but higher percentage of ESBL-production among MDR P. mirabilis in two of the states, Oyo and Lagos. Hence, there is need for adequate monitoring of antibiotic use to prevent increased rate of ESBL-positive MDR P. mirabilis in these states and others in the nearest future.
