A-Cal is used for the treatment or prevention of calcium depletion in various conditions, including:
- Calcium Deficiency: Hypoparathyroidism, vitamin D deficiency, pregnancy and lactation, menopause, chronic diarrhea, renal failure, etc.
- Hyperphosphatemia: Particularly in patients with chronic renal failure or on dialysis (CAPD and hemodialysis).
- Gastrointestinal Issues: Provides short-term relief from dyspepsia but is not recommended for long-term treatment of peptic ulcers.
- Calcium carbonate reacts with gastric acid to produce calcium chloride, water, and carbon dioxide, which raises gastric pH and decreases pepsin activity. Approximately 30% of oral calcium may be absorbed.
