None (7) · '"`UNIQ--vote-000009FD-QINU`"' Active against gram-positive cocci including MRSA; the unique target underlies the absence of cross-resistance with other antibiotic classes. High-level resistance (plasmid-mediated mupA) is rising and limits prolonged or repeated use'"`UNIQ--ref-000009FE-QINU`"'. (1) · '"`UNIQ--vote-00000D11-QINU`"' Same mechanistic family as amphotericin B but with prohibitive systemic toxicity at therapeutic doses, hence restriction to topical and luminal-gut indications.

(1) · '"`UNIQ--vote-00001233-QINU`"' Onychomycosis cure rates with nail lacquer are modest (mycologic cure ~30-50%, complete cure ~5-12% at 48 weeks); oral terbinafine remains substantially more effective when systemic therapy is acceptable'"`UNIQ--ref-00001234-QINU`"'. (1) · '"`UNIQ--vote-00001302-QINU`"' Renally cleared; accumulation in advanced CKD can produce neuromuscular and cardiac depression. Hypomagnesemia frequently co-exists with hypokalemia and is often the reason refractory potassium loss does not correct until magnesium is repleted. (1)
