Should not be triturated with acetanilid, anti-pyrine, camphor, monobromated camphor, hydrated chloral, menthol, phenol, phenyl salicylate, quinine sulphate or prescribed with spirit of nitrous ether or gold salts.
Antiseptic, 2 grains (0.125 Gm.); anthelmintic, 15 grains (1 Gm.) per day.
Eng., Thymol Iodide. Synonyms, Thymol Di-iodide, Aristol.
A brown or yellowish powder, almost odorless and insoluble in water. Sometimes used as a dusting powder for cutaneous lesions. Seldom employed.
Antiseptic, anthelmintic.
Principally employed for hookworms; also used in solution with other agents as a mouth-wash, nasal spray, gargle, etc., in the treatment of such conditions as nasal catarrh, stomatitis, pharyngitis and pyorrhoea alveolaris.
While Thymol is a constituent of some ointments, antiseptic solutions, etc., its more common employment is for intestinal parasites, particularly hookworm. For this purpose it is usually administered in doses of from 30 to 80 grains. It may be prescribed in a powdered state suspended in water by means of Acacia, but is more commonly administered in capsules, either alone or with sugar of milk. When well triturated with an inert powder, as sugar of milk, it is supposed to be less irritating to the gastric mucosa, and less apt to form concretions when the gelatin of the capsule is dissolved.
Not more than 5 to 7 grains of the powder should be prescribed to the capsule. As the safety of large doses depends on the comparative insolubility of the drug in the normal intestinal juices, care should be exercised that the patient has and keeps the intestinal tract free from alcoholics, oils and fats.
The drug should be eliminated promptly, as it is slightly soluble even in water. A common method of employment is as follows:
| or | ||
Thymolis, | |||
