monobasic sodium phosphate  the monohydrate, dihydrate, or anhydrous monosodium salt of phosphoric acid; used in buffer solutions. Used alone or in combination with other phosphate compounds, given intravenously as an electrolyte replenisher, orally or rectally as a laxative, and orally as a urinary acidifier and as an antiurolithic.

sodium monofluorophosphate  a dental caries prophylactic applied topically to the teeth.

sodium nitrite  an antidote for cyanide poisoning; also used as a preservative in cured meats and other foods.

sodium nitroprusside  an antihypertensive used in the treatment of acute congestive heart failure and of hypertensive crisis and to produce controlled hypotension during surgery; also used as a reagent.
