Sveppalyf

Sveppalyf is the Icelandic term for antifungal medications, a group of drugs used to treat infections caused by fungi. They can be applied topically to skin or nails, taken orally, or given by injection for systemic infections. Antifungals act by inhibiting fungal growth or killing fungi, often by targeting fungal membranes, cell walls, or DNA synthesis.

The major drug classes include azoles (for example fluconazole, itraconazole, ketoconazole, voriconazole), which disrupt ergosterol synthesis in the fungal membrane; polyenes (such as amphotericin B and nystatin), which bind ergosterol and form pores in the membrane; allylamines (like terbinafine), which inhibit squalene epoxidase and disrupt membrane synthesis; echinocandins (caspofungin, micafungin, anidulafungin), which block synthesis of beta-1,3-glucan in the cell wall; and antimetabolites such as 5-flucytosine, which interferes with fungal DNA synthesis.

Indications vary by agent and include superficial infections such as dermatophytosis and candidiasis, as well as systemic infections such as cryptococcal meningitis, histoplasmosis, and aspergillosis. Choice of drug depends on the site of infection, the responsible organism, patient factors, potential drug interactions, and toxicity risks. Side effects range from mild gastrointestinal symptoms to liver or kidney injury, infusion reactions, or hematologic effects, depending on the drug. drug interactions are common, especially with azoles and certain immunosuppressants.

Resistance can develop through mutations or efflux mechanisms, underscoring the importance of appropriate diagnosis, susceptibility testing when available, and adherence to recommended treatment durations and monitoring. In clinical practice, sveppalyf require careful selection and monitoring to maximize efficacy and minimize adverse effects and resistance.
