User: I have a question about the molecule with SMILES CN1CCC(=C2c3ccccc3CC(=O)c3sccc32)CC1.
Assistant: Sure, what is your question?
User: Please describe this drug.
Assistant: The answer is Ketotifen is a cycloheptathiophene derivative with anti-allergic activity. Ketotifen selectively blocks histamine (H1) receptors and prevents the typical symptoms caused by histamine release. This agent also interferes with the release of inflammatory mediators from mast cells involved in hypersensitivity reactions, thereby decreasing chemotaxis and activation of eosinophils.
