The "International Go-operation on Harmonisation of Technical Requirements
for Registration of Veterinary Medicinal Products (VICH)" is an internation
al programme of co-operation between regulatory authorities and the animal
health industries of the European Union, Japan, and the United States of Am
erica which aims to harmonise the technical requirements for the registrati
on of veterinary medicinal products. Australia and New Zealand participate
as active observers. The objective of the present paper is to present the g
uidelines established by the working group on Anthelmintic Efficacy Guideli
nes: (1) efficacy of anthelmintics: general requirements (VICH GL7); (2) ef
ficacy of anthelmintics: specific recommendations for bovines (VICH GL12);
(3) efficacy of anthelmintics: specific recommendations for ovines (VICH GL
13); (4) efficacy of anthelmintics: specific recommendations for caprines (
VICH GL14). These guidelines do not consist of rigid stipulations, but make
clear recommendations on the minimal standards needed. To the veterinary p
rofession, livestock producers and animal owners, harmonisation should mean
quicker access to safer and more effective veterinary anthelmintics. In ge
neral, products should be relatively more affordable because of the reducti
on in registration costs and efficient use of resources by the regulatory a
uthorities. (C) 2001 Elsevier Science B.V. All rights reserved.
