Question
Answer
show Sodium Bicarb: systemically absorbed, and excessive amounts can cause metabolic alkalosis. Because of the systemic absorption, sodium bicarbonate is rarely used for the treatment of peptic ulcers. Calcium Carbonate: can lead to hypercalcemia.  
🗑
Non-Systemic Antacids   show
🗑
show agents that neutralize stomach acidity (hydrochloric acid), lower pepsin activity, and raise the gastric pH (do not protective barrier or coating over the ulcer)  
🗑
show aluminum compounds, magnesium compounds, calcium compounds, and sodium compounds  
🗑
show can cause constipation,  
🗑
show can cause diarrhea
