- Pharmacodynamics
Isothipendyl, an azaphenothiazine derivative, competitively binds to histamine (H1) receptors, resulting in inhibition of the pharmacological effects of histamines. It also has some sedative, anticholinergic and antiserotoninergic effects.
- Mechanism of action
Isothipendyl is a selective histamine H1 antagonist and binds to the histamine H1 receptor. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine.

- General Function
- G-protein-coupled receptor for histamine, a biogenic amine that functions as an immune modulator and a neurotransmitter (PubMed:33828102, PubMed:8280179). Through the H1 receptor, histamine mediates the contraction of smooth muscles and increases capillary permeability due to contraction of terminal venules. Also mediates neurotransmission in the central nervous system and thereby regulates circadian rhythms, emotional and locomotor activities as well as cognitive functions (By similarity)
