What is the use of this drug?xasten

It appears to be a "trade name" of a drug and not the active ingredients. But I am sure someone with more knowledge of drugs will be able to help.

Using the BNF [British National Formulary] the closest match is Zasten, and it is a trade name for a drug with the active ingredients of "ketotifen fumarate". It is also listed as "Antihistamine" so it may be some sort of allergy/hypersensitivity drug.

Please this is just my understanding and not in anyway the correct answer. as drug are a bit more complex than that.

A quick check also shows that there are contra indication I.e. Some nasty side effect and if you have certain existing conditions, using this drug may cause severe or fatal damage. E.g Adrenal suppression and possible psychiatric reactions. The information is a lot, but I just thought I should post this for you.
