broad-spectrum

A term most commonly applied to antibiotics implying that the drug is effective over a wide range of organisms. Widely applicable or effective. Prolonged use of broad-spectrum antibiotics, such as AMPICILLIN or the CEPHALOSPORINS, will usually destroy most of the normal organisms of the bowel and these will tend to be replaced by resistant species. It is therefore considered better practice to use narrow-spectrum drugs so long as these are known to be effective against the organism concerned.
