Chapter 3, Problem 3CT
Summary Introduction
To discuss:
The possible ways that a new chemotherapeutic drug may act selectively on bacterial cells not humans.
Introduction:
A German physician, Paul Ehrlich, observed that chemicals with selectively toxic affect kills only pathogens and do not harm the cells of humans. He identifies a toxic molecule (magic bullet) that specifically binds to pathogens and destroys them.

Broad-spectrum drugs target a wide variety of bacterial pathogens. Even when the broad-spectrum drug is capable of killing a target pathogen, it may not be the best treatment.
Which statement best explains why a broad spectrum drug might be an undesirable treatment choice?
Broad-spectrum antimicrobials are usually toxic to the host cells.
Broad-spectrum antimicrobials only work if they are used shortly after the infection begins.
Broad-spectrum antimicrobials may kill much of the normal microbiota.
Broad-spectrum antimicrobials are not able to kill bacteria that are in their log phase of growth.
Broad-spectrum antimicrobials may stimulate excess growth of the normal microbiota.

- Read this article and answer the following question There are 3 different Metformin ER products available: Glucophage XR Glumetza ER Fortamet ER All 3 formulations are available generically but they are not interchangeable as they all use different release mechanisms. Glucophage XR uses a dual hydrophilic polymer system. The drug is slowly released by diffusing through a gel matrix, also known as GelShield diffusion system. Once the tablet is swallowed, the outer layer of the tablet forms a gel layer and the metformin contained within is slowly released. Due to this release mechanism, Glucophage XR can not be cut or split. Glumetza ER uses a mechanism known as gastro-retentive technology (also known as 'Modified Release'). The tablets are designed to remain in the stomach and deliver metformin to the upper GI tract over an extended period of time. Like Glucophage XR, Glumetza ER can not be cut or split. Fortamet ER uses single-composition osmotic technology (SCOT).
