Antacids: Calcium Carbonate and Magnesium Compounds Essay.
CLASSIFICATION OF ANTACIDS Antacids can be classified into two main classes based on the mechanism used to counteract the stomach’s acidity. One class works by chemical neutralisation of gastric acid (absorbable antacids) and the other class acts by absorption of the acid (non-absorbable antacids).
ANTACIDS - Classification and Mechanism of Action INTRODUCTION Antacids are defined as a substance, generally a base, which counteracts stomach acidity. The name antacid means anti-acid (against acid). Antacids are the primary treatment for ailments such as gastric reflux, gastritis, upset stomach and heartburn.
Antacids are medicines that counteract (neutralise) the acid in your stomach to relieve indigestion and heartburn. They come as a liquid or chewable tablets and can be bought from pharmacies and shops without a prescription. When antacids are used. Antacids may help if you have: indigestion.
Luckily, antacids being a weak base can help relieve the symptoms and pain. Antacids, such as Gelusil, Medi-Firs, Alka Seltzer, and Alcalak are neutralizing agents of acids that become helpful to the human body when heartburn occurs.
Calcium carbonate antacids are used in conditions of calcium deficiency such as postmenopausal osteoporosis since some of the calcium is absorbed into the body. Magnesium oxide antacids are used to treat magnesium deficiencies from either diets or medications that cause magnesium depletion.
Antacid medicines - Introduction. Antacids are a type of medication that can control the acid levels in your stomach. They're available over the counter from pharmacies and are often used to treat the symptoms of heartburn and indigestion. How antacids work.
Antacids are a type of medication, which corrects the pH balance in your stomach. A pH scale is a scale that ranges from 0-14, with 0 being the most acidic, 7 being neutral, and 14 being most basic. There are many types of antacids, such as sodium bicarbonate (contains baking soda), calcium carbonate, there is also aluminum and magnesium based antacids.
In general, antacids taken on an empty stomach have a duration of action of approximately 30 minutes, whereas antacids taken after a full meal may neutralize acid for 3 hours. Four primary compounds are currently used, alone or in combination, in antacid products: sodium bicarbonate, magnesium hydroxide, aluminum hydroxide, and calcium carbonate ( Table 28-4 ).

Are there different types of antacids? Yes, and in this eMedTV segment, we discuss three of the most common: sodium, calcium, and magnesium. This page covers the benefits and risks of each type, and gives several examples of brand names.
Equilibrium and Acid-Base Chemistry. Neutralisation of Stomach Acid by Magnesium Hydroxide Antacid. Abstract: An experimental investigation was conducted to examine the chemical concepts of acid-base chemistry and equilibria in the form of a neutralisation reaction, with real world applications of indigestion in the human body.Using an antacid with the active ingredient of magnesium hydroxide.
Some antacids are combined with an alginate (an insoluble substance that increases surface tension in liquid) to form a compound that floats on gastric fluids to protect the esophagus from acid exposure. Antacid tablets are slow acting and have less neutralizing power than a liquid form of antacid.
CLASSIFICATION OF ANTACID (a) Systemic (Absorbable) antacid These are soluble, readily absorbable and capable of producing systemic electrolytic alteration and alkalosis. Ex- Sodium Bicarbonate, Sodium citrate. (b) Non systemic (Non absorbable) antacids These are not absorbed to a significant extend thus do not exert on appreciable systemic effect.
An antacid used for the symptomatic relief of heartburn, acid indigestion, and sour stomach. Magaldrate: An antacid used to treat various conditions in the GI tract, such as esophagitis, duodenal and gastric ulcers, and gastroesophageal reflux. Aluminium: A metallic element that has the atomic number 13, atomic symbol Al, and atomic weight 26.98.
