Quinazolinone derivative that inhibits Cryptosporidium parvum development and suppresses prolyl-tRNA synthetase, preventing parasite protein synthesis.
Narrow safety margin — toxic dose is close to therapeutic dose. Avoid in dehydrated or debilitated animals. Do not exceed recommended dose.
Species-specific contraindications and adverse-reaction reports for chickens may differ from canine / feline reference data — consult the primary citations listed with each rule.
