Information from a comprehensive drug surveillance programme is analysed to provide details of antibacterial drug use in medical wards. Some 28% of patients received antibacterial therapy, usually for the treatment of respiratory or urinary tract infections. The agents most frequently prescribed were ampicillin, co-trimoxazole and tetracyclines. Overall, 11% of recipients experienced one or mo...

Seven-membered heterocyclic [1,2,5]triazepane and [1,2,5]oxadiazepane derivatives were synthesized as candidate structures for application in drug discovery in place of conventional piperazine or morpholine moieties, offering multiple sites for modification with functional groups. We first synthesized the N-protected heterocycles, and then confirmed their utility by synthesizing analogues of th...

Nearly all clinically used antibiotics have been (1) discovered from microorganisms (2) using phenotype screens to identify inhibitors of bacterial growth. The effectiveness of these antibiotics is attributed to their endogenous roles as bacterial warfare agents against competing microorganisms. Unfortunately, every class of clinically used antibiotic has been met with drug resistant bacteria. ...

Nitrofurazone is one of the antibacterial nitrofuran agents used topically for skin infections. The drug is effective on the majority of infectious microorganisms. Because of the importance of this drug in clinic, in this study various methods of synthesis of nitrofurazone were examined and the most appropriate method, applicable to pharmaceutical industry was chosen and optimized from the poin...

In this paper, we attempt to summarize developments ofimportance for practising hospital clinicians and for primary care doctors who must be aware of the ever-widening spectrum of recognized pathogens. This article is restricted to considerations of pathogenic bacteria and antibacterial drugs that have obliged us to change our strategies or policies in the last decade or so. There have been man...

The present study describes the preparation of a carrier system based on zinc-alginate beads and to evaluate its potential for the controlled release of rifampicin, the poorly water soluble drug using ionic gelation technique. The surface topology of the developed beads were analyzed by Scanning Electron Microscopy and the crosslinking process was investigated by Fourier Transform. Infrared spe...

A well known anti-cancer lignan arctiin has not been studied for its antibacterial activity based on our literature search. In the present work, the antibacterial and general toxicity of the arctiin from the seeds of Centaurea sclerolepis is studied. Arctiin did not show any significant antibacterial activity against both Gram-positive and Gram-negative bacteria when compared with the positive ...

Silver nanoparticles have been prepared by a one-pot synthetic technique using the antibacterial drug, Ciprofloxacin (Cp), under optimized conditions. Several techniques are used to characterize the free and nanoparticle bound states of Cp. The time dependent release of the drug molecules from the nanoparticles proves its importance in drug delivery.
