A well - make out erectile disfunction drug might just have added benefits for dogs , too . A recent study intimate that liquid sildenafil , the fighting component in Viagra , may help treat dog with an enlarged oesophagus that makes them unable to eat solid food easily and can sometimes prove fatal . More research will be needed to substantiate the drug ’s benefits for these frank , however .
The condition is know asmegaesophagus . It can affect many mammals , world and bounder include , and can be because of other diseases . The gorge , the vacuum tube that carries solid food from the mouth to the belly , not only becomes enlarged but also loses its power to push down solid food . This leads to food and body of water getting stuck in the esophagus , and dogs will often sick a repast before it can reach the stomach . Because afflicted dogs are n’t let much actual nutrition , the shape can lead to slow starvation . Other times , mo of nutrient will go down the windpipes to the lungs instead , get a var. of pneumonia that can work deadly if untreated .
Vets usually stress to handle megaesophagus by treating the underlie consideration if possible . dietetical change orfeeding dogs uprightcan also sometimes reduce the risk of vomiting , and in more life-threatening case , Canis familiaris may be given a eating subway instantly to their stomach . But there are no specific drugs useable that are recollect to help regenerate the oesophagus ’s power to do work as usual .

Sildenafil primarily affects the body by relaxing , or dilating , descent vessels . Though this avail men with cavernous disfunction , it ’s also used to treat a shape of high blood pressing in both man and dogs . The drug ’s dilation gist made the authors of this recent study , publishedlast calendar month in the American Journal of Veterinary Research , question if it could help with megaesophagus too .
Their small study demand 10 favored dogs with the status . For two weeks each , the dogs were randomize to receive a course of liquid sildenafil and a course of instruction of placebo ( if a hot dog was given the placebo first , for example , they would get the sildenafil subsequently after a week - longsighted break , and frailty - versa ) . Before and at the start of either discussion , the authors measured via X - ray how well the esophagus functioned at move food for thought down to the venter . They demand owner to keep track of how many episodes of regurgitation the dogs had at home over the next two weeks .
The writer did n’t find a pregnant remainder in how tight the esophagus moved food along in either scenario . But when the dogs were on sildenafil , the owners reported few bouts of regurgitation compared to baseline and to when they were on placebo . The hot dog also advance some system of weights back ( about 2 pounds on average ) while on sildenafil , and there did n’t appear to be any major side effects report .
“ If you look at the literature , there are no drugs we can practice to manage megaesophagus . Sildenafil is the first to target these mechanism and boil down vomiting , which is bad because that ’s what at long last vote out these Canis familiaris , ” co - author Jillian Haines , a veterinarian at Washington State University , toldlocal sensitive outlet KOIN . “ It opens the lower esophageal sphincter muscle for 20 minute to an hour , which works really well for dogs because we only require that to open when they are eating . ”
Haines says that she ’s since prescribed sildenafil to some of the owners involve in the study , who are keep on to use it with their dogs . But more enquiry will have to be done to validate the potential benefits seen in this small study , and the drug may not operate well for all unnatural dogs . In the survey itself , sildenafil reached the dogs ’ stomachs only 70 % of the sentence , and it seemed to be less effective for dogs that were more frequently sick to get going with .
Still , give the limited options available for this condition , the team hopes that more veterinary research worker will be able to stick with up on their work .
“ I think sildenafil will be life - commute and life - saving for a lot of dogs , ” Haines say . “ This inquiry serve bear out its utilisation and hopefully will encourage more people to practice it . ”
