9.4.3 Repeat Dose Dermal Studies in Rabbits (TSCATS 1988)

In a repeat dose dermal study, rabbits, 5/sex, received topical application of 2 mL per kg bwt per day of Varisoft 475 at dose levels of 3 or 27 mg active compound per kg bwt per day for 13 weeks (91 days). Animals at both doses had slight to moderate erythema, oedema and desquamation. There were no treatment related changes in body weight. No treatment related changes were observed in clinical pathology, bone marrow smears, organ weights, microscopic changes in skin or histopathological changes to internal organs. The reported NOEL for systemic toxicity was 27 mg active compound per kg bwt per day. In other repeat dose studies of 14 day or 91 day duration (no other details provided), no effects other than skin irritation were reported for Varisoft 475 (FSQSC 1988). The NOELs from the studies on Varisoft 475 are tabulated below.

 

Exposure Duration	Highest Dose Tested	NOEL (systemic effects)
14 days 7 hours, 5 days/week*	600 mg/kg bwt	600 mg/kg bwt/day
91 days 7 hours, 5 days/week**	27 mg/kg bwt	27 mg/kg bwt/day
91 days 7 hours, 5 days/week*	300 mg/kg bwt	300 mg/kg bwt/day
91 days 7 hours, 5 days/week*	400 mg/kg bwt	400 mg/kg bwt/day
