2. ANTACID Our stomach produce dilute hydrochloric acid
(HCL) helps in digestion to our food without
harming the stomach ,Sometimes the excess of
acid is produced in the stomach which cannot
treat with the dilute hydrochloric acid (HCL)that
will harm us in the stomach, to prevent from
acidity we use the bases called as “Antacid”.
Antacid reversibly reduce or block the
secretion of acid by gastric cells to reduce
acidity in the stomach.
3. ABOUT ANTACID
Chemical substances which remove the excess
acid and raise the pH to an appropriate level in
stomach are called “Antacid”.
Acid gastric is a very common aliment associated
with digestion and is caused by an excess of
Hydrochloric Acid(HCl) in the gastric juice. The
commonly used Antacids are;
Magnesium Hydroxide.
Magnesium Carbonate.
Magnesium Trisilicate.
Aluminium Hydroxide gel.
Sodium Bicarbonate.
Aluminium Phosphate.
4. COMPONENTS OF ANTACID
Antacids are weak bases that are used to
neutralize excess stomach acid
Most antacids are weak inorganic bases
Common examples include:
CaCO3 (CALCIUM CARBONATE )
NaHCO3 (SODIUM
BICARBONATE )
Al(OH)3 (ALUMINIUM
HYDROXIDE)
Mg(OH) (MAGNESIUM
5. INDICATIONS WHEN WE TAKE ANTACID
When heart burn is there then we take Antacid
to reduce the heartburn.
Treatment with antacids alone is symptomatic
and only justified for minor symptoms.
A typical feeling of restlessness.
Indigestion.
Feeling of nausea (wanting to throw up) and
actual vomiting.
6. CAUSES OF EXCESSIVE RELEASE
OF ACIDS IN THE STOMACH
Alcohol Consumption.
Eating Certain Foods.
Smoking.
Certain Drugs i.e. Aspirin.
Stress.
7. REACTION OF ANTACID
Antacids react with HCl in the stomach
Some common antacid reactions
include:
CaCO3 + 2 HCl CaCl2 + H2O +
CO2
NaHCO3 + HCl NaCl + H2O +
CO2
Al(OH)3 + 3 HCl AlCl3 + 3 H2O
Mg(OH)2 + 2 HCl MgCl2 + 2 H2O
MgO + 2 HCl MgCl2 + H2O
8. USES OF ANTACID
It bring down the percentage of Acidity
in our Stomach and prevent mucus
lining in the stomach.
It prevent from HEART BURN
It also prevent from the
ULCER(damage to lining of stomach
wall, resulting in loss of tissues and
inflammation).
9. SIDE EFFECT OF ANTACID
Magnesium Compounds may cause
diarrhea
Aluminum Compounds may cause
constipation and they also may interfere with
the adsorption of phosphates in the formation of
bones
Calcium compounds containing may also
increase calcium output in the urine, which
might be associated with kidney stones.
Sodium : Increased intake of sodium
may lead to heart failure and many renal
