Intervet/Schering-Plough has launched Vectin chewable tablets, an ivermectin wormer for horses which is administered as a treat straight from the hand rather than in the traditional paste or granule formulation. 

According to the company, syringe handling, horse acceptance and the tendency to spit out some or all of the paste are common problems reported by owners when worming their horses, and more than 55% admit that these issues can result in a mixture of emotions, including frustration, anxiety and upset.

Field studies with Vectin showed more than 70% spontaneous acceptance by horses and the simple calculation of one tablet for every 110kg of a horse or foal's bodyweight helps to reduce wastage as unused tablets can be stored away for future use.

Pharmacokinetics studies have demonstrated improved bioavailability (AUC) and maximal concentration (Cmax) when compared with an equivalent competitor ivermectin paste formulation. Trials have also shown that a more consistent blood concentration of ivermectin when given as a chew which could potentially limit the chance of inducing resistance.

Intervet/Schering Plough says that used as part of a strategic worming plan, Vectin chewable tablets control potentially a wide range of endoparasites including small and large strongyles, stomach worms, cutaneous worms and stomach bots.

Vectin chewable tablets are available as a seven-tablet blister pack, perfect for treating a horse or a couple of ponies. For yards, a tub of 60 tablets is available, containing enough to dispense product for worming approximately 12 horses.

Vectin chewable tablets are recommended for use alongside Pyratape P and Panacur in Intervet/Schering-Plough Animal Health's Active3 worming plan, a strategic three-year approach to rotating wormers in order to minimize the risk of resistance developing.  Visit http://www.intervet.co.uk/ for a copy of the three-year plan.
