Property Insights of Flezelastine

The XLogP value of 5.8 indicates that Flezelastine is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 35.9 Ų, Flezelastine exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Flezelastine has 0 hydrogen bond donor(s) and 4 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
