| sodium iodide | <chemical> Sodium iodide (nai). A compound forming white, odourless deliquescent crystals and used as iodine supplement, expectorant or in its radioactive (I-131) form as an diagnostic aid, particularly for thyroid function determinants. Chemical name: Sodium iodide (NaI) (12 Dec 1998) |
| sodium iodide iodine-131 | Prepared from radioactive iodine (131I); practically carrier-free, with a half-life of 8.0 days; used as a diagnostic agent in suspected thyroid disease and in the treatment of selected thyroid diseases. (05 Mar 2000) |
| sodium isotopes | Stable sodium atoms that have the same atomic number as the element sodium, but differ in atomic weight. Na-23 is a stable sodium isotope. (12 Dec 1998) |
| sodium lactate | The sodium salt of racaemic or inactive lactic acid. It is used intravenously in a one-sixth molar solution as a fluid and electrolyte replenisher to combat acidosis. (12 Dec 1998) |
| sodium lauryl sulfate | CH3(CH2)10CH2OSO3Na;a surface-active agent of the anionic type. (05 Mar 2000) |
| sodium levothyroxine | 3,3',5,5'-tetraiodothyronine pentahydrate;Sodium salt of the natural isomer of thyroxine, a thyroid hormone. It is twice as effective as the racaemic form. Used in the treatment of hypothyroidism in humans and animals and to treat lowered fertility in bulls and to stimulate lactation in animals. (05 Mar 2000) |
| sodium liothyronine | Sodium l-triiodothyronine, the physiologically active isomer of triiodothyronine, twice as active as the racaemic form; used in the treatment of thyroid deficiency syndromes. (05 Mar 2000) |

| sodium methicillin | Sodium 2,6-dimethoxyphenylpenicillin monohydrate;a semisynthetic penicillin salt for parenteral administration; restriction of its use to infections caused by penicillin G-resistant staphylococci is recommended; it is less effective than penicillin G in infections caused by haemolytic streptococci, pneumococci, gonococci, and penicillin G-sensitive staphylococci. Synonym: sodium methicillin. (05 Mar 2000) |
| sodium methylarsonate | Ch3H5O(ONa)2-5H2O; disodium monomethyl arsonate;formerly used in tuberculosis, chorea, and other affections in which the cacodylates were used. (05 Mar 2000) |
| sodium methylprednisolone succinate | Sodium 6-methylprednisolone 21-succinate;it has the same metabolic and anti-inflammatory actions as the parent compound, methylprednisolone; because of its solubility it can be administered in small volumes. (05 Mar 2000) |
| sodium morrhuate | <chemical> The sodium salts of the fatty acids in cod liver oil; an irritant and sclerosing agent used to treat varicose veins and arthritic joints. Pharmacological action: sclerosing solutions. Chemical name: Sodium morrhuate (12 Dec 1998) |
