Nitenpyram (Capstar) is a nicotinic acetylcholine receptor agonist used for flea control in dogs.

There is little residual effect of this antiparasiticide beyond a 24 hour period compared with imidacloprid and is mainly used for immediate knockdown effect[1].

This drug should also be considered in cases of myiasis due to fly larvae, e.g. Cochliomyia hominivorax[2].
