In this season, from March to May, it is a season of frequent allergic diseases. Common are allergic rhinitis or allergic conjunctivitis. Because the eyes and nose are connected through the lacrimal passage and can interact with each other, the symptom is itching.
There are several kinds of eye drops commonly used in hospitals.
1 antihistamine/decongestant compound preparation
The so-called antihistamines are the most common antiallergic drugs, such as chlorpheniramine, which is well known.
This kind of eye drops takes effect quickly, has obvious decongestant effect, has certain antihistamine effect, and is mostly used to relieve all kinds of pressure or non-infectious envy and itching, such as swimming, smoke, dust, sandstorm, overuse of eyes, chemicals and so on.
This is the kind of eye drops you mentioned. Let's look at the composition of naphthalene.
Contains naphazoline hydrochloride 0.2 mg, chlorphenamine maleate 2 mg, and vitamin B 12 1 mg.
Among them, chlorpheniramine maleate is the scientific name of chlorpheniramine, naphazoline is used to relieve eye congestion and envy, vitamin B 12 is used to nourish corneal nerves, and some potions also add a little sodium hyaluronate as artificial tears to relieve dry eye.
2. Mast cell stabilizer: Stabilize mast cells to prevent them from degranulation and release inflammatory mediators. There is no effect on the released inflammatory mediators, and the clinical efficacy will not be shown until the released inflammatory mediators are metabolized. The clinical effect is relatively slow, but it is safe to use, can be used for a long time, and is suitable for prevention or early treatment and drug maintenance treatment.
The most common and cheapest is cromoglycate eye drops.
Glucocorticoid: Non-specific control of allergic reaction, characterized by rapid onset, good effect, but large side effects, only suitable for short-term treatment of critically ill patients.
The eye drops commonly used in clinic include iodophor, Belide, Flumerone, etc.
According to your situation, you can choose two kinds of eye drops, Naminwei eye drops and cromoglycate sodium eye drops, which are used at intervals of half an hour, so that antihistamines and mast cells can work stably at the same time, and any drug has adaptability and inadaptability. The above eye drops are cheap, clinically universal, safe and reliable. However, due to different personal qualities, a small amount can be used first, and it can be used for a long time without discomfort.
The first medicine is a little more expensive, Nastar eye drops and Emmedine eye drops.
The second medicine is more expensive, which is eye drops.
Of course, there is a new kind of eye drops that can play two roles at the same time, that is, Patanro eye drops, which are imported, very expensive and not worth using!
Second, when wearing contact lenses, of course, it is best not to drip, because you can't completely contact your eyes. Look at the water on the contact lens for at least 15 minutes before wearing it!
The composition of eye drops is the highest in purity and accuracy among all drugs, so eye drops can be used in the nose, but the water used in the nose can't be used in the eyes, so it is definitely no problem to use a little eye drops in the nasal cavity, not to mention the lacrimal passage of the eyes and the nasal cavity are connected, and whoever orders the medicine will get some into the nasal cavity.
If you have severe allergic rhinitis, you should also take oral antiallergic drugs, not lightly.
Houttuynia cordata Thunb Or all kinds of eye drops to improve vision are only used for mild symptoms and adjuvant treatment. If you want to stop itching, you should also use the above professional potions.
