"Most interesting, a recent report (Bucchi et al., 2006) indicates that ivabradine blocks HCN1 in a use dependent manner via the closed state, but HCN4 via a voltage dependent, open state mechanism."

reach
"Ivabradine inhibits HCN1 either in the closed state or in a transitional state between closed and open, and the direction of current flow has little effect on block."

reach
"Nevertheless, it was interestingly shown that, on the contrary to HCN4 and native I f, ivabradine is able to block HCN1 in the closed state (Bucchi et al., 2006)."

reach
"53 However, the HCN1 antagonist ivabradine, approved in Europe for angina, does not cross the blood-brain barrier."
