Generic versus innovator: Analysis of the pharmaceutical qualities of paracetamol and ibuprofen tablets in the Nigerian Market

Abstract 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...

Antimicrobial and Pharmaceutical Properties of The Seed Oil of Leucaena l eucocephala (Lam.) De Wit (Leguminosae)

ABSTRACT The seed oil of Leuconia leucocephala was investigated for its antimicrobial activity and the pharmaceutical properties of its lotion formulation determined. The oil was extracted from the pulverised dried seeds of the Leuconia leucocephala plant by cold maceration in n-hexane.  The oil was tested against four bacteria (Staphylococcus aureus, Esherichia coli, Bacillus subtilis and Pseudomonas aeruginosa) and four fungi (Aspergilus niger, Rhizopus stolon, Penicillum no...

Evaluation of Mucoadhesive Properties of Native and Modified Starches of the Root Tubers of Cocoyam ( Xanthosoma sagittifolium )

ABSTRACT The purpose of this study was to evaluate the bioadhesive properties of native and modified cocoyam (Xanthosoma sagittifolium) starches. The methods of modification were by pregelatinisation and acetylation. The starch particles  were evaluated for characteristics like particle size, swelling ability, viscosity, and mucoadhesion.  The mucoadhesive evaluation of the starches were done using the rotating cylinder methods in 0.1M HCl  and Phosphate buffer (pH ...

Design of Bilayer Tablets Using Modified Dioscorea Starches as Novel Excipients for Immediate and Sustained Release of Aceclofenac Sodium

Abstract Bilayer tablets of aceclofenac sodium were developed using carboxymethylated whit yam (Dioscorea rotundata) starch (CWY) for a fast release layer (2.5, 5.0, and 7.5% w/w), and acid-hydrolyzed bitter yam (Dioscorea dumetorum) starch (ABY) for a sustaining layer (27% w/w). Sodium starch glycolate (SSG) and hydroxypropyl methyl cellulose HPMC)were used as standards.The starches were characterized using Fourier Transform Infrared spectroscopy (FT-IR), particle size, swelling pow...

Incidence, Molecular Characterization And Sensitivity To Buchholzia Coriacea Leaf Extract Of Methicillin Resistant Staphylococcus Aureus Nasal Isolates From Tertiary Institution Students In D

ABSTRACTThis study investigated the incidence, molecular characters and sensitivity to Buchholziacoriacea leaf extract, of methicillin-resistant Staphylococcus aureus (MRSA) nasal isolatesfrom tertiary institution students in Delta State. Nasal swabs were collected with sterile swabsticks from nine hundred (900) apparently healthy students in the study areas and cultured onmannitol salt agar. The bacterial isolates (S. aureus) were Gram-stained, and the Gram positiveisolates subjecte...

Formulation And Characterization Of Novel Pegylated Selfnanoemulsifying Formulations (Snefs) For Oral Delivery Of Gentamicin And Its Possible Use In The Treatment Of Pneumococcal Meningitis.

ABSTRACTThe solubility of gentamicin in various formulation vehicles (oils, surfactants and co-surfactants)was determined using the shake flask method. Emulsifying ability of the surfactants for theselected oil was screened. Different SNEF prototypes were developed following the constructionof ternary phase diagrams using water titration method. The effect of drug and other additives onthe ternary phase diagrams were studied and the selected formulations were optimized.Optimized formulat...

Optimization of Formulations of Metoprolol Succinate Tablets Containing Ofada Rice Starch Acetate as Tablet Matrix for Sustained Release Using Response Surface Methodology

Abstract Background: Release-retarding polymers in matrix tablets play a vital role in controlling drug release from tablets. Objectives: To prepare metoprolol succinate tablets by direct compression using Ofada rice (Oryza glaberrima Steud) starch acetate, degree of substitution (DS) 2.22, as a matrix for sustained release.  Materials and methods: The central composite design and response surface methodology were applied to evaluate the interactive effects of three variables: ...
