- Such substances are, for example, described in US Patents 3,950,360 and 4,199,569. It has often been proposed to combine parasiticides with the aim of broadening the antiparasitic spectrum and we have already mentioned, among many others, the combination of the above-mentioned derivatives of 1-N-phenylpyrazoles with avermectins, iver ectins and milbemycin, without, however, determining the particular interest that such an association could have, taking into account the numerous and complex host-parasite interactions.
- Patent application AU-A-16 427/95 mentions the association of a substituted 1-N pyrazole derivative of this type with avermectins, ivermectin or moxydectin, among a very large number of insecticides or parasiticides of different types, including fipronil, without, however, giving an indication of a composition comprising such an association, and without establishing a distinction concerning the targets likely to be targeted by particular associations, among the innumerable parasites which can potentially be affected.
