Yes. There is experience of the efficacy of the pulse itraconazole (200 mg twice daily, 1 week on, 3 weeks off, for 12 weeks) vs. continuous terbinafine (250 mg once daily for 12 weeks) oral therapies in the treatment of dermatophyte toenail distal and lateral subungual onychomycosis (DLSO) in normal patients and in the diabetic population. 

Dear Venkata, in case of onychomycosis, if toe nails also affected it is recommended to give Itraconazole pulse therapy twice a day in a dose of 200mg for 7 days then a lapse for 21 days and repeat for another 2 successive cycles i.e. 3 pulse doses 21 days in between.

single weekly dose of 400 mg itraconazole used instead of 200 mg twice day for seven days for tinea( pityriasis) versicolor. single dose appear to be  better for improving compliance and decreased cost of treatment.. for further information please go through article..

Single dose (400 mg) versus 7 day (200 mg) daily dose itraconazole in the treatment of tinea versicolor: a randomized clinical trial.

Most data indicate the use of itraconazole twice a day in a dose of 200mg for 7 days then a lapse for 21 days and repeatition for another 2 successive cycles. However, the possibility of a weekly administration appears very promising especially to improve the compliance and reduce the costs. Probably, it is necessary to perform other randomized trials.

Yes I agree as patients compliance is an important issue.
