Semisynthetic Penicillins |
|
Definition
Developed in an attempt to overcome the shortcomings of natural penicillin.
Made from naturally produced penicillin which is altered and added to in the lab.
Examples: Methicillin (this was the original semisynthetic which was used for penicillinase producing Staphylococcus). The emergence of MRSA strains have decreased the use of methicillin.

Term
|
Definition
Narrow spectrum for Gram positive. For many years this drug has been the last line of treatment for resistant strains of Staphylococcus aureus. Considered very toxic for years, new purification methods have greatly decreased the toxic effects of this drug. The emergence of Enterococcus strains (VRE) and Staphylococcus aureus strains that are ________-resistant are considered a medical emergency.

Very broad spectrum of activity that works on a wide variety of bacteria and penetrates body tissues well. Side effects include gastrointestional upsets, opportunistic infections (both in part due to their broad spectrum of activity), teeth discoloration in children, and liver damage,as well as, other potential problems if taken by pregnant women. Widely used as additive in animal feeds for weight gain.

Term
|
Definition
Narrow spectrum for Gram positive bacteria since it can not penetrate the wall of most Gram negative bacteria. It is often given to children as a substitute for penicillin. Two other drugs in the same class of macrolides are Azithromycin and Clarithromycin, both of which have a broad spectrum of activity and penetrate tissues better.
