Pastern Leukocytoclastic Vasculitis treatment with oral medication

My vet has supplied me with Trental 400 (oxpentifylline 400mg). This medication is used for treating Pastern Leukocytoclastic Vasculitis. 


Action of Trental 400 ...
Reduce blood viscosity, thus improving blood flow in the microcirculation and increasing tissue oxygenation.-Reduced blood viscosity may be due to improved red blood cell flexibility, decreased plasma fibrinogen and improved platelet deaggregation.


Archie weighs 540kg and we have had to give him 10 tablets in the morning and 10 tablets in the evening with his feed. We crush these tablets into a powder and mix it with molasses, barley flakes, chaff and a little bit of water. Archie will eat it this with no problems at all. He takes his medication for 3 days.

Day 1 of treatment after I removed the white ointment.

Day 3 of treatment. A big improvement

I have also been covering the area to protect the bare skin from UV light throughout Archie's treatment. I did not want the mesh wraps I made to rub the inflamed area so I used a disposable nappy as padding. I like this idea because the nappy wicks any moisture away from the sores and keeps the area dry. The outer plastic stops the rain from entering. I have secured the nappy on the hock with duct tape.

I then rugged Archie and put his mesh wraps over the top. The mesh boots are suspended from the leg straps of his rug. I have also duct taped the nappy to these leg straps. This stops the nappy from slipping down.

It's important to leave an opening at the back. So that the hock has room to move. This is easy to achieve because this is where the nappy's waistband is.

The mesh leg wraps strap over the top, hold everything together and shelter the rest of the leg from harmful UV light.

These mesh boots used to pull down on Archie's beige coloured rug. It made it hard for him to go to the toilet because he couldn't easily lift his tail. I would find him with a dirty mess of manure over his bottom and down his legs. Archie's new blue rug gives him more room to lift his tail. When I checked his bottom it was clean.

Unfortunately I found orange sores. There are about seven of them (pictured below). I'm not sure if these sores are side effect of the medication. I hope they heal easily.

Day 3, I noticed some unusual orange sores under Archie's tail.
I wonder if this may be a side effect of the medication.
The hair on his tail is a bit messed up so he has been rubbing.
