Ketotifen is an anti-allergic drug commonly used in clinical practice, generally used to treat allergic diseases such as allergic rhinitis, and has a good preventive effect on asthma attacks, especially for children's asthma prevention. Ketotifen can inhibit the central nervous system, and some adverse reactions may occur after taking it, such as nausea, vomiting, and dry mouth.
Ketotifen tablets are anti-allergic drugs. On the one hand, this drug has a certain antagonistic effect on histamine receptors because histamine is closely related to allergic reactions. Ketotifen fumarate also acts on the pathway of histamine, thus achieving anti-allergic effects. In addition, it can also inhibit the release of allergic reactions and mediators, and also has a certain anti-allergic effect. This drug not only has a strong anti-allergic effect, but also has a strong duration of effect. It can be used to prevent the onset of various bronchial asthma and exogenous asthma. Precautions for taking Ketotifen:
1. This drug has a slow onset, and the relieving effect on bronchial asthma generally appears gradually after continuous use for 2-4 weeks. Therefore, patients should be clearly explained before medication to cooperate with treatment.
2. This drug has a certain synergistic effect with sedative hypnotics and alcohol preparations. Concurrent use can enhance symptoms such as drowsiness and fatigue, which should be avoided.
