Tolfenamic acid exhibits pharmacologic actions similar to those of aspirin. It is a potent inhibitor of cyclooxygenase, thereby inhibiting the release of prostaglandins. It also has direct inhibition of prostaglandin receptors. Tolfenamic acid has significant anti-thromboxane activity and is not recommended for use pre-surgically because of its effects on platelet function.
Toltrazuril is an antiprotozoal agent that may be considered as an alternative treatment for coccidiosis in dogs and cats, Hepatazoon infections, or for treating the oocyst shedding stage of toxoplasmosis in cats. It has also been used as a treatment for overwhelming parasitic loads in lizards (Bearded Dragons). Toltrazuril has activity against parasites of the genus _Hepatozoon_, but other drugs ( _e.g.,_ imidocarb, primaquine, doxycycline) are generally used. While toltrazuril has been used to treat equine protozoal myeloencephalitis (EPM) caused by _Sarcocystis neurona_, use of approved products now available ( _e.g.,_ nitazoxanide, ponazuril, pyrimethamine/sulfadiazine) is preferred. Toltrazuril has been used in some countries to treat _Isospora_ _suis_ in piglets.
