Standard operating procedure for pH meter

 1). pH meters -  Objective:                      To demonstrate how to use a standard pH meter in the TRACES Centre and undergraduate laboratories. This process explains how to accurately test a solution's pH.  2. Scope: Digital pH meters in the TRACES Centre and the UG Laboratory are affected. These devices include (but are not limited to) Sartorius, Oakton, and Mettler-Toldeo.  3. Responsibility :   Designated persons in the research lab are responsible for training employees and students on this protocol and ensuring that it is followed. It is the responsibility of selected persons (Staff or Students) to adhere to the procedure's guidelines.  4. Equipment :  • pH meter, digital  • Double-junction Ag/AgCl electrode pH electrode  • ATC probe (automatic temperature control) (if available)  • Transfer utensils, pipettes, spatula or capillaries  • Clean stir bars on a stir p...

What are Antacids

What are Antacids

Antacids are a class of medicines that neutralize acid in the stomach. They contain ingredients such as aluminum, calcium, or magnesium which act as bases (alkalis) to counteract the stomach acid and lower pH. They work quickly and are used to relieve symptoms of acid reflux, heartburn or indigestion (dyspepsia).

Antacids are available as liquids or tablets. Some mixtures contain sodium and may not be suitable for people on a sodium restricted diet. Some products combine antacids with alginates and are used in the treatment of Gastroesophageal Reflux Disease (GERD). Alginates are gum-like substances that float on top of the stomach contents, forming a raft that acts like a barrier, preventing gastric acid from escaping back up the esophagus.

Antacids are usually only used short-term or occasionally. Longer acting medicines that work by reducing or preventing the secretion of stomach acid over a 12 to 24-hour period may be more effective for some people.

IMPORTANT PHARMACOLOGICAL TERMS

 IMPORTANT PHARMACOLOGICAL TERMS: •Antagonism -The opposition between 2 or more medications ex. narcotics and Naloxone •Bolus -A single, often large dose of a drug. Often the initial dose •Cumulative action -An increased effect caused by multiple doses of the same drug. Caused by buildup in the blood. •Hypersensitivity -A reaction to a drug that is more profound than expected and which often results in an exaggerated immune response •Idiosyncrasy -A reaction to a drug that is significantly different from what is expected •Indication -The medical condition for which the drug has proven therapeutic value. •Parentral  -any route of administration other than digestive tract •Pharmacodynamics  - study the mechanism by which drugs act to produce biochemical or physiological changes in the body •Pharmacokinetics - study of how drugs enter in the body reach their site of action and are eliminated from the body
