Gel (suspension), containing 90 mg of phosphate aluminum per 1 mL.
Gefal — is a nonabsorbable antacid, based on phosphate aluminum gel. The preparation exhibits acid-neutralizing, adsorbing and coating action. It rapidly decreases intracavitary acidity of gastric juice to physiological pH values. It maintains normal stomach acidity level, not interfering with digestion for a prolonged period of time. Due to the complex surface of gel particles it can bind and eliminate toxic substances from the stomach. It forms protective film on the mucosa of gastro-intestinal tract, promotes restoration of mucosa cells and ulcer healing.
In clinical practice is used as ready to use white viscous suspension, with sweetish taste, with aromatic flavor odor.
Following oral administration aluminum phosphate practically does not enter systemic blood flow. It is eliminated with faeces.
Gefal is intended for the treatment of peptic ulcer disease, gastroesophageal reflux disease, erosive gastritis; as symptomatic agent during dyspepsia, eructation and heartburn, as well as for prevention of mucosa lesions during therapy with agents having ulcerogenic properties.
