David Rendle presented his research Efficacy of a novel palatable pergolide paste formulation for the treatment of PPID in ponies at the BEVA conference in September 2018. Rendle suggested that the only form of pergolide currently licensed for horses in the UK, Prascend, is not always eaten readily and can be difficult to split and administer below half a tablet. A molasses-flavoured pergolide paste from BOVA UK that can be given in small doses was given to 19 ponies who had not responded well to Prascend, and their clinical records reviewed. They were considered to have PPID if their ACTH concentration was >50 pg/ml in July or >100 pg/ml from August to October. All the ponies were examined after 1 and 6 months of treatment and doses adjusted if necessary according to season. ACTH concentrations improved significantly and returned to normal in 74% of the ponies, clinical signs showed some improvement but some clinical signs either did not improve or became worse. 1 pony refused to eat the paste and 2 ponies went off their feed but this resolved when the dose was reduced.
The BOVA pergolide paste is currently not licensed, but may be used through the medicines cascade if Prascend (currently the only licensed form of pergolide) cannot be used (e.g. because it does not appear to be effective or causes significant side effects). The paste is available to horses in the UK through their vet. It may be possible to export to other countries if a vet in that country is prepared to import it (it cannot be distributed to anyone other than a vet).
