Nasal sprays are one of the main drugs used in the treatment of rhinitis and sinusitis, and there are many different types and different mechanisms of action. So, how should we use them regularly while minimizing the adverse effects of the drugs on the human body? First of all, we are going to introduce the nasal hormone. This kind of medicine includes mometasone furoate nasal spray, fluticasone propionate nasal spray, budesonide nasal spray, etc.. As the first-line drugs for rhinitis and sinusitis, they have powerful anti-inflammatory and anti-metabolic effects, but have little effect on the systemic cortical axis due to their low bioavailability. Like Mometasone furoate nasal spray each amount of about 50 micrograms, if two sprays a day, less than two micrograms. The effect on the human body is very small. Usually can be used continuously for three months, no hit to the body. However, for patients with nasal bleeding, direct spraying of the drug on the nasal septum should be avoided as it may cause bleeding. The second type of nasal spray drugs are antihistamines. This includes levocabastine, azelastine nasal spray. These drugs are mainly used for mild to moderate allergic rhinitis and are effective in relieving itchy nose and sneezing symptoms. They are widely used in clinical practice because of their rapid onset of action and low side effects. Sometimes it is also afraid to be used with nasal hormones for severe allergic rhinitis. The third type of nasal drugs is nasal decongestant drugs, commonly used preparations are hydroxymetazoline and serozoline nasal spray. They are mainly used for acute rhinitis and severe nasal congestion by constricting the nasal mucosa blood vessels to improve nasal ventilation. Continuous medication should not be used for more than one week. Because of long-term constriction of blood vessels, local mucosal malnutrition, can cause drug rhinitis. The fourth type of nasal spray is a drug to reduce nasal secretions, ipratropium bromide, which reduces the symptoms of runny nose by inhibiting glandular secretion, but many hospitals do not have such nasal sprays. The fifth type of common nasal spray is a drug for cleaning the nasal cavity, commonly used drugs such as Bonnetsongbao, Nasalang, etc. It is mainly used for cleaning the nasal cavity, reducing nasal crusting and reducing allergen adsorption in the nasal cavity. For rhinorrhea, nasal vestibulitis, rhinitis, sinusitis and other diseases have some auxiliary treatment effect. Some hospitals also have some nasal drops containing ephedrine, which can help improve the nasal congestion effect. However, considering the side effects on the cardiovascular system, this type of medication is rarely used in pediatric patients nowadays. Well, through the above few short paragraphs, do you know more about the common nasal drugs? Do you still have a lot of concerns when using nasal medications?
