What medicine does chronic rhinitis take
summary
Now many places develop their economy at the expense of the environment, leading to many people suffering from rhinitis, some chronic rhinitis. Let's share with you the drugs suitable for chronic rhinitis.
What medicine does chronic rhinitis take
Drug 1: antihistamines: allergic rhinitis and the release of chemicals after mast cells of nasal mucosa contact with allergens again, and the most important chemical substance is histamine. It causes vasodilation, increased permeability, and secretion of large amounts of nasal fluid. Antihistamines can compete with histamine for receptors on cell membrane; there are two kinds of receptors, H1 and H2. Antihistamines for rhinitis are antagonists against H1 receptor, while H2 receptor antagonists are mainly used for digestive ulcer.
Drug 2: mast cell stabilizer: by stabilizing the cell membrane, it can inhibit the degranulation of mast cells, that is, inhibit the release of active chemicals from mast cells (including histamine) to prevent the occurrence of allergic reaction. This kind of drug is called "mast cell stabilizer", and its effect is similar to that of antihistamine drugs. Ketotifen is the main mast cell stabilizer, which can treat asthma and allergic rhinitis. But the effect of nasal congestion caused by nasal congestion is not good, and there will be adverse reactions of drowsiness. Its efficacy can be maintained for 12 hours, so it can be taken orally once or twice a day. If you take this drug alone, the effect may not be significant. If you have allergic rhinitis, you'd better use antihistamines to enhance the effect.
Drug 3: vasoconstrictor: it belongs to sympathetic drugs, that is, to excite the α - and β - adrenergic receptors, so as to make the blood vessels constrict and achieve the effect of constricting blood vessels, so as to eliminate the symptoms of nasal congestion. Since sympathetic nerve stimulation may cause adverse reactions, such as elevated blood pressure, it should be avoided in elderly patients or patients with stroke, coronary artery disease and hypertension. It can also cause urethral sphincter contraction, making it difficult to urinate, so the symptoms of patients with prostatic hypertrophy will aggravate after use, which is not suitable for use.
