RESUMO

The microbial and chemical analysis of illicit drug samples from different areas of Pakistan i.e. Quetta, Karachi, Lahore and Islamabad was conducted in a cross-sectional study at National Institute of Health, Islamabad. The drug samples were confiscated by Anti Narcotics Force [ANF], Pakistan. Microbial analysis was done by estimating bioburden which revealed the presence of gram negative and positive bacteria's, fungus, Streptococcus, Staphylococcus species. Trypton soya agar was used for total aerobic count, MacConkey agar for gram-negative bacteria, Sabouraud dextrose agar for fungus and Vogel-Johnson agar for Streptococcus and Staphylococcus species. Colour tests were applied to identify the drug samples. Qualitative and quantitative analysis of suspected samples of Heroin, morphine, cocaine and acetic anhydride was made by employing different chromatographic techniques i.e. Thin-layer chromatography [TLC] and High-performance liquid chromatography [HPLC]. The samples were found to be adulterated with paracetamol, diazepam and Dextromethorphen. Acetic anhydride was adulterated with hydrochloric acid [HCl]. There is lack of information providing structured advice on responses to the consequences of illicit drug adulteration. Robust and rehearsed interventions and communication strategies would provide a basis for response for a wide variety of organisations. Research into the usefulness of media warnings about adulteration of illicit drugs is required

RESUMO

Medicinal plants are crucial for about 80% of the world population in developing and developed countries for their primary and basic health care needs owing to better tolerability, superior compatibility with human body and having lesser side effects. The present study was conducted on various solvent extracts of three plant samples of Indian and Nepali origin Swertia Chirayita [Roxb.] Buch-ham [Chiratia] collected from various places to establish their comparative phytochemical analysis, chromatographic profile, hepatoprotective and antioxidant activities. Nepali Swertia Chirayita was found to have finest Chromatographic profile [TLC]. Phytochemical analysis revealed Alkaloids, flavonoids, saponins, ascorbic acid, glycosides, steroids and triterpenoids in all samples. Different solvent fractions of the methanolic plant extracts of Swertia chirayita were assessed for hepatoprotective activity by carbon tetrachloride-induced liver damage in rats. The grade of protection was measured by using biochemical parameters such as serum glutamate oxalate transaminase [SGOT/AST], alkaline phosphatase [ALP], serum glutamate pyruvate transaminase [SGPT/ALT] and total bilirubin. The in-vitro antioxidant activity of the extracts was also evaluated by the 1, 1-diphenyl-2-picrylhydrazyl [DPPH] free radical scavenging assay. The methanolic and aqueous extracts, at a dose of 200 mg/kg and 300 mg/kg, produced significant [P<0.05] hepatoprotection by decreasing the activities of the serum enzymes and bilirubin while there were marked scavenging of the DPPH free radicals by the fractions. Decreased observed in the biochemical parameters suggests that the plant extracts possesses hepatoprotective as well as antioxidant activities without any significant variation amongst them. These activities reside mainly in the methanolic extract of whole plant

RESUMO

Tetanus is an acute illness represented by comprehensive increased inflexibility and spastic spasms of skeletal muscles. The poor quality tetanus toxoid vaccine can raise the prevalence of neonatal tetanus. WHO has taken numerous steps to assist national regulatory authorities and vaccine manufacturers to ensure its quality and efficacy. It has formulated international principles for stability evaluation of each vaccine, which are available in the form of recommendations and guidelines. The aim of present study was to ensure the stability of tetanus vaccines produced by National Institute of Health, Islamabad, Pakistan by employing standardized methods to ensure constancy of tetanus toxoid at elevated temperature, if during storage/transportation cold chain may not be maintained in hot weather. A total of three batches filled during full-scale production were tested. All Stability studies determination were performed on final products stored at 2-8 Degree C and elevated temperatures in conformance with the ICH Guideline of Stability Testing of Biological Products. These studies gave comparison between real time shelf-life stability and accelerated stability studies. The findings indicate long-term thermo stability and prove that this tetanus vaccine can remain efficient under setting of routine use when suggested measures for storage and handling are followed in true spirit

RESUMO

The astounding and exceptional growth of generic pharmaceutical Industry in Pakistan has raised certain questions for drug regulatory authorities contemplating their efficacy and quality. The current study focuses on assessing the in-vitro antimicrobial activity of 24 brands of Cephradine 500mg capsules against 4 different strains by employing standardized methods. Disk diffusion method was performed on all brands to look into the susceptibility and resistance patterns. Standard disk of 5 micro g Cephradine powder were used during evaluation. The zones of inhibitions were ranged from 24-40mm against S. aureus, 24-40mm against E. coli, 20-25mm against K. pneumonia and 19-23mm P. mirabilis. On the basis of mean value, the multinational brands were found to have better zone of inhibitions and were better than local Pharmaceutical companies but ANOVA cooperative study showed that all brands of Cephradine showed similar comparable results. Further investigations by employing MIC method, quality of raw material with special emphasis on the shelf-life, excepients and method of manufacturing will be needed to obtain more authenticated results. The price of National and Multinational brands ranges from Rs.156.00-212.00 for 10 capsules. It is concluded that Public health is at risk because of noticeable growing widespread curse of the manufacture and trade of sub-standard or below par pharmaceuticals. The pecuniary accountability of management of pharmaceutical agents is additionally apparent. The results of the study need to be made public to boost the confidence of medical profession about the quality of locally manufactured pharmaceuticals. It will succor the foreign exchange being incurred on the trade in of medicines

RESUMO

Niosomes has gained tremendous popularity as ultimate drug carrier. Lot of research work is being carried out on preparation of niosomes for ophthalmic use having no significant effect on vision and its sustained release pattern. Chloramphenicol niosomes were prepared using two different ratios of cholesterol, drug and surfactant, termed as EIN-1, EIN-2 by ether injection method and their entrapment efficiency, particle size. The in vitro drug release pattern was observed for ten hours. The EIN-2 showed 90% entrapment and released 81% of entrapped drug after 10 hours. Zeta potential and viscosity were determined and in vivo comparison was made with Chloramphenicol eye drops where it exhibited Cmax of 15 microg/ml. Stability studies were done to determine shelf life. MIC of selected strain of S. aureus was also determined. EIN 2 niosomal suspension was compared with Chloramphenicol eye drops in experimental conjunctivitis in albino rabbits. In vitro studies are encouraging as niosomes released about 75% of total entrapped drug by EIN-1 and 81% of total entrapped drug by EIN-2. In vivo study shows that niosomes released the drug in eye in acceptable range and showed a sustained release pattern without affecting the vision. Niosomes were found ultimate ophthalmic drug carriers capable to release drug in sustained and determined pattern
