Dimenhydrinate functions as an antagonist of histamine H1 receptors. It acts by competitively inhibiting the binding of histamine to these receptors, thereby preventing the activation of the receptors and subsequent signaling cascades. At the molecular level, dimenhydrinate interacts with the histamine H1 receptors on target cells, blocking the binding of histamine and preventing the downstream effects of histamine signaling.
