The goal of treatment for tinea pedis is to clear the pathogenic bacteria, provide rapid relief and prevent recurrence. In principle, topical medications such as bifenoconazole cream, miconazole, econazole, ketoconazole, sertaconazole and terbinafine ointment are the main ones, but it is easy to find that they all have the word “azole” in their names. These two types of drugs are currently the most important drugs used to treat ringworm infections, so you can generally choose one. The common “Dakine” is miconazole nitrate ointment, which belongs to the azole class; some preparations with keratin exfoliation also have certain antifungal effects, such as salicylic acid and benzoic acid, etc. The common “Foot Light San” contains both of these preparations. So many people will react when using “the skin on the feet are off a layer”, it is because of its strong keratin exfoliation; there is another one that we often use is “Parezon”, professionally named tretinoin econazole cream, which is actually a compound This is actually a compounding agent. The so-called compound preparation is two or more different utility of the drug together, and “Parezon” is “tretinoin” and “Econazole” of the compound preparation, the former belongs to The former is a hormone and the latter is an azole antifungal. This combination can be used for the treatment of ringworm with heavy inflammation, but care should be taken to avoid the adverse effects of glucocorticoids, and it is recommended to apply it for a limited period of 1-2 weeks and then switch to a single antifungal drug until the lesions clear. A similar drug is “Dermacare”, which is a combination of ketoconazole and clobetasol propionate (also a hormone). Therefore, we should be careful when purchasing medication on our own, and not just look at the trade name, but also at the professional name. The selection of drugs and formulations for the local treatment of tinea pedis can be based on the following criteria: 1. blister type: milder solutions and cream preparations can be used, such as 1% terbinafine spray, 2% miconazole nitrate cream or 2% ketoconazole cream. 2, inter-rubbing erosion type: generally use the powder first, and then use the solution or cream preparation after the local lesions are dry, such as 2% miconazole nitrate bulk, 2% miconazole nitrate cream or 2% ketoconazole cream, etc. 3.scaly keratinized type: you can choose cream or ointment preparation, with keratin exfoliating agent if necessary. 4.Mixed type: treat separately according to different types, and bulking agent, cream or spray can be used in combination. The dispersant can be sprinkled in shoes and socks, and then combined with ointment or cream, both for synergistic treatment and to effectively prevent recurrence or reinfection. 5.Stubborn type: For patients with poor local treatment, extensive lesions or recurrent attacks, or lesions of the keratinized thickening type, macerated erosion type, or combined with other systemic diseases that are not conducive to the cure of tinea pedis, such as immune deficiency, in addition to topical medications, oral antifungal drugs such as itraconazole, terbinafine, fluconazole, etc. can also be considered for faster onset and better results. 6. Combined “gray nail”: “Gray nail” is tinea nail, and many patients who do not recover from tinea pedis often develop tinea nail, and the two are often causal, so if a patient has combined tinea pedis and tinea nail, they should be treated together.
