Tenilapine is an atypical antipsychotic which has never been marketed in the US.

Pharmacodynamics

Tenilapine has a relatively high affinity for the 5-HT2A receptor, and relatively low (micromolar) affinities for dopamine receptors.

Binding affinities
Receptor Ki (nM)
D2 1584[1]
D4 721±300[1]
5-HT2A 40[1]

The ratio of D2 to D4 bonding is similar to that of clozapine.[1] Like many other atypical antipsychotics, it is a potent 5-HT2C antagonist.[2]
