| carbonate dehydratase | <enzyme> A zinc-containing enzyme of erythrocytes with molecular weight of 30 kD. It is among the most active of known enzymes and catalyses the reversible hydration of carbon dioxide, which is significant in the transport of co2 from the tissues to the lungs. The enzyme is inhibited by acetazolamide. Chemical name: Carbonate hydro-lyase Registry number: EC 4.2.1.1 (12 Dec 1998) |

| carbonate dehydratase inhibitor | An agent, usually chemically related to the sulfonamides, that inhibits the activity of carbonate dehydratase, producing a general decrease in the formation of H2CO3 in the tissues. See: acetazolamide, dichlorphenamide. Synonym: carbonic anhydrase inhibitor. (05 Mar 2000) |

| magnesium carbonate | Used in gastric and intestinal acidity and as a laxative. (05 Mar 2000) |
| precipitated calcium carbonate | CaCO3;used as an antacid in the management of peptic ulcers and other conditions of gastric hyperacidity. (05 Mar 2000) |
| sodium acid carbonate | <chemical> Carbonic acid monosodium salt (CHNaO3). A white, crystalline powder that is used as an electrolyte replenisher and systemic alkaliser. It is applied topically in solution to wash the nose, mouth, or vagina, and as a cleansing enema. Pharmacologic action: Acid neutralization. Uses: Preexisting metabolic acidosis, hyperkalemia, tricyclic or phenobarbital overdose. Dose in mEq: 0.3 * (base deficit) * (wt in kg). Potential complications: Metabolic alkalosis, hypercarbia, hyperosmolar state. Note: Since HCO3- does not cross cell membranes and CO2 does, the administration of bicarbonate may actually make tissues more acidotic. Chemical name: Carbonic acid monosodium salt. (12 Mar 2000) |
| sodium carbonate | Na2CO3-10H2O;used in the treatment of scaly skin diseases; otherwise rarely used in medicine because of its irritant action. Synonym: sal soda, soda, washing soda. (05 Mar 2000) |
| sodium hydrogen carbonate | <chemical> Carbonic acid monosodium salt (CHNaO3). A white, crystalline powder that is used as an electrolyte replenisher and systemic alkaliser. It is applied topically in solution to wash the nose, mouth, or vagina, and as a cleansing enema. Pharmacologic action: Acid neutralization. Uses: Preexisting metabolic acidosis, hyperkalemia, tricyclic or phenobarbital overdose. Dose in mEq: 0.3 * (base deficit) * (wt in kg). Potential complications: Metabolic alkalosis, hypercarbia, hyperosmolar state. Note: Since HCO3- does not cross cell membranes and CO2 does, the administration of bicarbonate may actually make tissues more acidotic. Chemical name: Carbonic acid monosodium salt. (12 Mar 2000) |
| dihydroxyaluminum sodium carbonate | Aluminum sodium carbonate hydroxide;a gastric antacid. (05 Mar 2000) |
| lead carbonate | A heavy white powder that is insoluble in water; occasionally, it is used to relieve irritation in dermatitis, but it is used largely in the manufacture of paint and in the arts and is thus productive of lead poisoning. Synonym: ceruse, white lead. (05 Mar 2000) |
