this is a tract that includes the mouth, stomach, small intestine, large intestine, rectum, anus, and its accompanying exocrine glands.
Gastrointestinal tract
is secreted by the stomach to kill harmful organisms, aid digestion and active digestive enzymes
hydrochloric acid
cause gastric reflux, gastritis, upset stomach, and heartburn
hyperacidity
are weak alkaline compounds used ti neutralize hydrochloric acid in the stomach
antacids
(neutralizes acid for indigestion relief) work by counteracting, or neutralizing, any excess stomach acid
antacids
occurs due to excessive secretion of HCl in the stomach due to various reasons
gastric acid
creates protective reflux barrier
Alginate
what are the criteria of an ideal antacid preparation
> Antacid
Alginate
Combination products
show the most rapid onset of action and provide faster relief symptoms, however may cause “acid rebound”
absorbable antacid
less prone to cause a rebound effect: are more potent and effective on a semi liquid or liquid form than in a capsule or table
Non Absorbable Antacid
their anionic group neutralizes H+ ions in gastric acid
non systemic antacid
have cationic group that does not form insoluble compounds
systemic antacid
its side effects are metabolic alkalosis edema due to sodium overload, hypernatrimia, hypertension due to increased sodium
sodium bicarbonate
its side effects are constipation and osteomalacia
aluminum hydroxide
used for short time to treat occasional constipation
magnesium hydroxide
are chemical agents applied to the skin and mucous membranes for localized effects within skin or membrane
topical drugs
it is any agent that isolates the exposed surface of the skin or other membranes from harmful stimuli
protectives
used in reducing or preventing infection due to microorganism
local anti-infectives
are protein precipitates with limited penetration power.
Astringents
used as a protective, dusting powder, glidant and should not be applied to the skin when the epidermal barrier is missing
Talc
is used as an astringent, topical protective, antiseptic and its side effect is itching when added too much
Zinc oxide
is used as topical protective, used in lotions & ointments, as soothing agent and used in sunburns
Calamine
used as an anti-septic for washing wounds, teeth and ears
Hydrogen Peroxide
used as antiseptic, antioxidant and for cleaning wound and dermatitis
potassium permanganate
is a stable chemical complex of polyvinylpyrrolidone and elemental iodine
povidone Iodine
the substances used to produce effect on teeth and in dental cavity
dental products
prevents tooth decay
anticaries agent
materials used to clean the accessible surface of the teeth using preferable a toothbrush
dentrifices
an agent that gives polishing effect on the clean teeth
polishing agents
an agent used to reduce sensitivity of teeth to heat/cold
desensitizing agent
used as an anticaries agent and prophylaxis of dental caries
sodium flouride
is made of complex silicates of Al, K and Na. Is used as a polishing agent
pumice
is used as a polishing agent, manufacture of dental products and is also used as a dentrifice
calcium carbonate
is used as an astringent, mild antiseptic, desensitizing agent
zinc chloride
