VI. Autonomic Nervous System Drugs (ANS)

These drugs are designed to influence the functions of the autonomic
nervous system or involuntary nervous system. The autonomic nervous
system functions to sustain homeostatic mechanisms within an organism just as
importantly assists in internal bodily reactions to stressful conditions. The
autonomic nervous system regulates such functions as respiration, heart rate,
blood pressure, gastrointestinal motility and secretion, urinary output as well as
many other body functions.

 Epinephrine
 Atropine
 Neostigmine

VII. Digestive System Drugs

Digestive system drugs and/or substances are used to treat digestive disorders,
just as the name implies. They are made up of stomachic (which are drugs or
substances which are beneficial to digestion in the rumen of a cow), ruminators
which basically do the same thing, carminatives which control flatulence,
antizymotics which arrest fermentation, antacids such as sodium bicarbonate and
magnesium hydrochloride which counteract stomach acid, laxatives which induce
movement in the intestine and loosens the stool, and purgatives which cause
cleansing of the digestive tract and colon. The chart below shows some very
common digestive system drugs.
