Comparison of ivermectin, oxfendazole and levamisole for use as anthelmintics during the periparturient period in sheep.

Ewes synchronised with progestin impregnated sponges to reduce the spread of lambing were treated during the periparturient period with anthelmintic. The suppression of nematode egg output in faeces was measured in ewes given ivermectin either by subcutaneous injection or orally, or oxfendazole or levamisole orally. Ivermectin and oxfendazole reduced the output of eggs in the faeces of the ewes significantly (P less than 0.05) and the period of suppressed egg output was extended when ivermectin was given by subcutaneous injection. Plasma pepsinogen activity was estimated as a measure of abomasal damage. Pepsinogen values were significantly (P less than 0.001) lower in those animals treated with ivermectin by subcutaneous injection than in control animals. Levamisole showed a poorer response in terms of the output of eggs in faeces than either ivermectin or oxfendazole.

Pharmacokinetics of oxfendazole in goats: a comparison with sheep.

In goats, there was a linear correlation of area under the plasma concentration-time curve (AUC) with dose in the range 0-20 mg/kg as single dosages of oxfendazole (OFZ). The bioavailability of OFZ after oral administration was lower in goats than in sheep. The repetition of three administrations at 24 h intervals produced significant increase in the AUC in comparison with a single administration equivalent to the total dosage (1 X 5.0 and 3 X 1.7 mg/kg). Infection with O. circumcincta produced a 33% decrease in the bioavailability of OFZ.

Albendazole--objective evidence of response in human hydatid disease.

Thirty-two patients with cysts caused by Echinococcus granulosus were treated with albendazole in a dosage of 10 mg/kg/day. Reversible abnormalities in liver-cell function tests were seen in five patients. Some radiological evidence of remission (on serial computed tomographic or ultrasound scanning) was seen in 15 of 22 patients undergoing a therapeutic course of albendazole (as opposed to those treated before or after surgery). In five patients, the cysts virtually disappeared. Apart from reduction in size, the appearance of a halo around the cysts and the apparent disappearance of daughter cysts has been seen. Serological findings have not correlated well with radiological or clinical improvement. Serum and cyst concentrations of albendazole sulfoxide (the principal metabolite) have been measured.
