Enzymes – a drug that binds to the

physiological response.
b) Rapid-Ligand-Gated Ion Channels
– the drug spans the cell membrane
& with this type of receptor, the
channel opens, allowing for the flow
of ions into & out of the cells. The
ions are primarily sodium & calcium

systems – there are 3 components to
this receptor response: the receptor;
G protein that binds with guanosine
triphosphate (GTP); the effector that
is either an enzyme or an ion channel

the drug binds to the transcriptase
factor to undergo a physiological
change.

Categories of Drug Action (MTC).
 Drugs are categorized by the type of
action it causes on the body. There
are four types of responses:
a) Stimulation or depression – these
are drugs that either increase or
depress cellular activity
b) Replacement – these are drugs that
replace an essential body compound
such as insulin or estrogen
c) Inhibition – these drugs interfere
with bacterial cell & limit bacterial
growth or eliminate the bacteria
d) Irritation – these drugs irritate cells
