Turns antacids

Iron absorption occurs predominantly in the duodenum and upper jejunum. The physical state of iron entering the duodenum greatly influences its absorption. At physiological pH, ferrous iron is rapidly oxidized to the insoluble ferric form. Gastric acid lowers the pH in the proximal duodenum, enhancing the solubility and uptake of ferric iron. When gastric acid production is impaired, iron absorption is reduced substantially. Ascorbic acid enhances iron absorption. Ascorbic acid mobilizes iron from iron-binding proteins in vivo, which in turn could catalyze lipid peroxidation. Iron absorption is inhibited by antacids, phytates, phosphates and tetracyclines. 

All the materials are in a powdered condition except the No 1 mixture, where half of die K chlorate is powdered and half of it is granular. The sulfur, which is contd in No 2 and No 3 mixts, makes them more sensitive, but also may make them turn sour after wetmixing of the components. In order ro prevent this, small amts of antacids (such as Ca... 

Calcium carbonate(eg, Turns, Os-Cal) is less soluble and reacts more slowly than sodium bicarbonate with HC1 to form carbon dioxide and CaCl2. Like sodium bicarbonate, calcium carbonate may cause belching or metabolic alkalosis. Calcium carbonate is used for a number of other indications apart from its antacid properties (see Chapter 42 Agents That Affect Bone Mineral Homeostasis). Excessive doses of either sodium bicarbonate or calcium carbonate with calcium-containing dairy products can lead to hypercalcemia, renal insufficiency, and metabolic alkalosis (milk-alkali syndrome). 

Besides the active ingredients, antacid tablets also contain inactive ingredients, such as starch, which act as a binder or filler. The efficacy of an antacid tablet is its ability to neutralize HC1. The more HC1 that is neutralized, the more effective the antacid pill. (You must have heard the competing advertisement claims of different commercial antacids Turns neutralizes one-third more stomach acid than Rolaids. )... 

Harry Mann is the 64-year-old owner of a furniture removal business, Kwik Move. Kwik Move provides a good income, but Harry is ambitious. He is not a patient man his quick temper makes his relationships with employees tricky. He has recently been stressed out by his van driver s frequent, unexplained absences. Harry works 12 hours a day, smokes continually, hasn t had a day off in 30 years and has no time for anyone with problems. On Monday, he arrives at work early after his usual greasy breakfast fry-up and a long wait in traffic. The van driver has not turned up again and Harry is furious. He decides to drive the van and move the client s furniture himself. Arriving at the client s house, Harry soon feels very unwell. He is weak and breathless, has a sharp pain in his chest and nausea two antacid tablets do not help. He moves a couple of packing cases and his chest pain worsens. Fortunately, the house owner insists on taking Harry to the local hospital. 

Add vinegar dropwise to the antacid solution and monitor the solution by using another piece of blue litmus paper. Record the number of drops needed to turn the litmus paper bright red.

Turns and Di-Gel represent another type of antacid. The active ingredient in these is ordinary calcium carbonate, CaC03, a compound present in enormous quantities on the earth in the form of seasheUs, corals, and limestone. Calcium carbonate reacts with acids to produce water and carbon dioxide, as well as a calcium salt. 

Diuretics, by increasing kidney output, deplete calcium, magnesium, potassium, and zinc. This, in turn, depletes energy and lowers immune function. Over-the-counter antacids, as well as the peptic ulcer medication cimetidine, reduce iron and calcium assimilation, vitamin Bj , and intrinsic factor (without which Bi2 can t be absorbed). Drugs prescribed for heart disease reduce libido, and some of them render men impotent. 

The TG curves of the antacids are given in Figure 4.36. As expected, the TG curves are not so helpful for qualitative identification purposes as are the DSC curves. Similar features, such as the % values, were observed for Alka Seltzer, Bromo-Seltzer, and Citrocarbonate. Likewise, 7] values for Phillips, Turns, and Rolaids were similar. There were enough differences in the TG curves of Alkaid, Rolaids, Kolancyl, and Triactin to be useful for qualitative identification purposes. 

Prehospital. Do not induce vomiting because of the risk of abrupt onset of seizures and arrhythmias. Administer an antacid containing calcium (eg, calcium carbonate [Turns, Rolaids]) orally to raise gastric pH and complex free fluoride, reducing absorption. Foods rich in calcium (eg, milk) can also bind fluoride. Magnesium-containing antacids have also been recommended but there are little data for their effectiveness. 

Molecules are the fundamental components of matter. They are made up of atoms, which in turn are composed of even smaller particles called protons, neutrons, and electrons. Perhaps it isn t really surprising that people have misconceptions about molecules, since molecules are almost inconceivably small — much too small to be seen. So, how do we know that they exist The simplest answer may be that our ideas about molecules must be correct because we can predict and explain the behavior of matter based on the concept that everything is made up of molecules. Examples range from explanations for why taking an antacid helps heartburn to why adding an acid to milk causes it to curdle. 

Red cabbage contains a material that makes an acid-base indicator. Place two cups of chopped red cabbage in a blender, cover with boiling water, and blend. Use a coffee filter to filter out the plant material. Add the indicator to materials like lemon juice, baking soda, antacids, and seltzer water. The indicator will turn red/purple/violet in the presence of acids and blue/green/yellow for bases. 

The properties of bases are bitter taste, slippery feel, and the ability to turn red litmus paper blue. Some common substances that contain bases are ammonia, Drano, baking soda, and antacids.
