These are preparations for applying volatile drugs to the air-passages for the purpose of deodorising, disinfecting, stimulating or soothing. The drug is mixed with water and the vapour inhaled. If the drug be not readily volatile, warm water is used, as in the vapor creasoti, or the water is warmed during inhalation, as in the vapor iodi. In the vapor olei pini sylvestris, light carbonate of magnesium is added, to aid the suspension of the drug in the water.

The vapours of chlorine, creasote, and iodine may be used for deodorising in cases of ozaena or in cases of chronic bronchitis with offensive sputa.

Antiseptic inhalations, such as those of creasote and iodine, as well as non-officinal inhalations of iodoform and oil of pine, have been recently used in the treatment of phthisis, with the object of destroying the tubercle bacillus. For this purpose a special form of inhaler is used, which fits over the mouth and nose. It contains a sponge which is soaked with the drug to be inhaled either pure or dissolved in spirit or water.

They are probably also useful even in simple catarrh, by destroying organisms which may have found their way into the air-passages and occasion or keep up inflammation. The vapours of hydrocyanic acid and conium are useful for the purpose of allaying irritability, as in spasm of the glottis, violent coughing, or spasmodic asthma.

Vina. Wines. - These are made in the same way as tinctures, sherry or orange wine (B.P.) or stronger white wine (U.S.P.) being employed instead of spirit.
