Fawar Lemon Effervescent Salt Sachet contains highly palatable and pleasant tasting sugar-free formulation for flatulence, indigestion, urine alkalinization and hyperchlorhydric dyspepsia. When added to water, the contents of each sachet interact to give carbon dioxide, sodium tartrate and sodium citrate. The administration of such mixture during effervescence results in immediate and rapid antacid action due to neutralization of HCI in the stomach, with a rapid improvement of dyspepsia caused by hyperchlorhydria. The gentle pressure induced by carbon dioxide stimulates intestinal peristalsis while the produced sodium tartrate causes mild laxation due to its poor absorption. Sodium citrate, on the other hand, is metabolized in the body to sodium bicarbonate which is excreted in the urine causing mild increase in its pH to the alkaline side. This is useful in reducing imitation in inflamed urinary tract and when long-term maintenance of an alkaline urine is desirable as in patients with urinary urate and cysteine calculi and during treatment with sulfonamides. Moreover, being sugar-free, Fawar lemon effervescent Granules are the drugs of choice for patients on a low carbohydrate regimen.
