Drug resistance limits the therapeutic uses of antibacterial agents in animals and man. Antibacterial drug resistance develops in bacteria rapidly due to their short generation time and easy genetic exchange mechanisms. Drug resistance is also observed with protozoa, helminthic parasites and malignant cells. Resistance in bacteria spreads from animals to animals or from bacterium to bacterium by plasmids and from [...]
After reading this article we will learn about the various drugs acting on skin and mucous membrane of an animal. Classification: 1. Demulcents: (i) Gum acacia (ii) Gum tragacanth (iii) Glycyrrhiza (liguroice) (iv) Glycerine (v) Propylene glycol (vi) Methyl cellulose (vii) Glycerine of starch (8.5% starch and 74.5% glycerine in D.W.). (viii) Mucilage of starch (2.5.% starch). 2. Emollients: (i) [...]
Sulfonamides are synthetic chemotherapeutic agents. They were in common use as antimicrobial drugs prior to the advent of antibiotics. Frequent development of cross drug resistance in bacteria isolated from animals has now-a-days reduced their clinical values. Recently their use in combination with trimethoprim or orimethoprim is favoured on account of synergistic action and prevention of emergence of resistant bacteria. In [...]
