Nasal spray

Applying inside the nasal cavities drugs in "spray" form either for preventive purpose or for curative purpose, for example to treat diseases of the nasal cavities (rhinitises, sinusitises, and so on) and/or to make the patient take by the nasal mucosas drugs assigned to carry out their action in other body regions is a well known and widely consolidated practice. Common nasal sprays contain, almost obligatorily, vessel-constricting substances for reducing the swelling of the mucous membrane, often also cortisone. While cortisone has known negative side effects, the medications, which simply reduce the swelling of the mucous membrane, can result in regeneration breakdowns of the nasal mucous membrane and physical dependency. Ailments of the upper respiratory tract, such as the common cold, frequently involve sore throats. Various types of vaporizing ointments are widely used in relieving the discomfort accompanying colds and sore throats. An example is Vicks VapoRub. Vaporizing ointments are generally applied to the throat and chest of the patient. These ointments typically include ingredients which open the pores and make the throat and chest feel warm. The warmth helps the patient to feel more comfortable. Vaporizing ointments also include various vaporizing ingredients. The vaporizing ingredients may have a decongestant effect so that the patient feels he is breathing easier. The vaporizing ingredients may also include perfumes of various sorts, which help to distract and relax the patient. Typical ingredients of a vaporizing ointment include menthol, camphor, eucalyptus oil, and spirits of turpentine.
