Ingredients
The active ingredient of Capstar, nitenpyram, is a novel molecule belonging to the chemical class of neonicotinoid compounds, which bind with and inhibit insect specific nicotinic acetylcholine receptors; however, it does not inhibit acetylcholinesterase. It interferes with normal nerve transmission and leads to the death of the fleas.
Nitenpyram is very rapidly and almost completely absorbed from the gastrointestinal tract of cats and dogs; feeding does not influence absorption. On average, the maximum blood concentration is reached 1 hour (range: 15 to 90 minutes) after administration in both species, and the elimination half-life is about 3 hours in dogs and 7.5 hours in cats. More than 90% of the active ingredient is eliminated in the urine within one day in dogs and two days in cats, mainly as unchanged nitenpyram.
Nitenpyram starts working rapidly after dosing and kills >98% of the fleas on the pet within 6 hours; all adult fleas are eliminated 24 hours after a single treatment.
