What is antacid pharmacology?
Pharmacology. Antacids are basic compounds which neutralize hydrochloric acid in the gastric secretions. For this purpose, the following are used: sodium hydrogen carbonate, aluminum hydroxide, aluminum phosphate, algeldrate, calcium carbonate, magnesium(hydr)oxide, magnesium carbonate, and magnesium trisilicate.
How does an antacid work?
Antacids help to treat heartburn (indigestion). They work by neutralizing the stomach acid that causes heartburn. You can buy many antacids without a prescription. Liquid forms work faster, but you may like tablets because they are easy to use.
What is an antacid in chemistry?
Abstract. Antacids are relative simply assembled salts and salt-like compounds which neutralize acids. This neutralization reactions lead to several products (other salts, water, and possibly carbondioxid), resulting in steps, like hydrolysis and precipitations of insoluble compounds.
What is antacid and its classification?
Antacids are a class of medicines that neutralize acid in the stomach. They contain ingredients such as aluminum, calcium, magnesium, or sodium bicarbonate which act as bases (alkalis) to counteract stomach acid and make its pH more neutral.
How do antacids affect drug absorption?
Antacids interfere with gastrointestinal drug absorption by either increasing or decreasing the rate at which a drug is absorbed, or the total quantity absorbed. Antacids influence drug absorption by alteration of ionization state or solubility, factors dependent upon pH.
Why do antacids cause drug interactions?
Antacids that contain magnesium trisilicate and magnesium hydroxide when taken with some other medications (such as tetracycline) will bind to the drugs, and reduce their absorption and effects.
