When the throat is scratching and the nose is running, sprays and aerosols are often used. Sprays are fast and accurate. They allow a very fine distribution of a drug. In addition to sprays with propellant there are pump sprays that release the drug through a pumping mechanism.
Advantages of sprays and aerosols
Although there are rinsing or gargling solutions with anti-inflammatory agents for sore throat and pharyngitis. But for those to be effective, the solution must have long-term contact with the mucous membrane: the patient has to gargle long enough.
For many patients it is very uncomfortable to gag up to half a minute. Some people even fear that they swallow the often spicy-tasting solution.
In this case, sprays and aerosols are used. Depending on whether the sprays are used as nasal or throat spray or as asthma aerosol, the different applications must be considered.
For nasal sprays, keep the head straight and the spray bottle vertical. Thus, the spray adheres optimally to the nasal mucosa and the active ingredient can be properly absorbed.
In throat sprays, the fine spray should not be inhaled, because then he can not stick to the almond in the mucous membrane. For this, the opening of the spray bottle should point to the suppository or slightly above it. Inhalation is prevented by saying "aaa" loudly while spraying deep into the mouth.
Even if the sprayed solution may initially leave a bad taste, you should never rinse immediately with a glass of water. This only achieves that the active substance is removed again and healing does not occur.
Dosing aerosols are small, high-pressure gas containers and effective for the Treatment of asthma essential. With each spray, a certain amount of drug is delivered by means of a propellant gas. In this way, a precisely dosed amount of active ingredient is released as a fine mist and absorbed by simultaneous inhalation.
Note the following tips for using dosing aerosols:
- Shake the spray vigorously before use
- Hold the box upside down and remove the protective cap
- The mouthpiece with the lips tightly enclose
- exhale deeply
- Take a deep breath while simultaneously triggering the spray
- Stop air for five to ten seconds
- then exhale slowly through the nose
If inhaled cortisone aerosols or children need to use the spray, so-called spacer be helpful in different designs and sizes. Spacers are large volume spacers that facilitate the inhalation of the spray. The sprayed into the spacer aerosol is inhaled in several breaths, the exhaled air is discharged through a special valve.
Cleaning the spacers
Because plastic charges electrically over time, spacers need to be cleaned regularly, even if they do not look dirty. If the spacer is electrostatically charged, the aerosol will stick to the wall of the spacer instead of entering the lungs. It is enough to unscrew the spacer and clean it with detergent. If it is rinsed with clear water, the spacer must then dry in the air.
When drying with a towel, the plastic surface of the spacer would recharge electrically due to the friction.
