Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to microtubule-associated proteins and disrupts fungal mitotic spindle formation, thereby inhibiting fungal cell division. It also interferes with fungal nucleic acid synthesis.
Myhibbin is a selective inhibitor of inosine monophosphate dehydrogenase (IMPDH), thereby blocking the de novo synthesis of guanosine nucleotides. This inhibits T- and B-lymphocyte proliferation and antibody production.
500 mg orally once daily (non-microsize formulation) or 250 mg twice daily; typical duration is 4-8 weeks for tinea capitis, 2-6 weeks for tinea corporis, 4-6 weeks for tinea pedis.
