Betaxolol 0.25% ophthalmic solution is an effective, safe, and pain-relieving treatment for patients suffering from EGFR inhibitor-induced paronychia with pyogenic granuloma-like lesions and deep fissures.
Common adverse events include diarrhea, skin rash, dry skin, and paronychia; however, because it spares wild-type EGFR, these toxicities appear to occur with less frequency and severity compared to other TKIs.
Although EGFR TKIs are commonly associated with skin-related (rash, xerosis and paronychia) and gastrointestinal-related (diarrhea and stomatitis) adverse events (AEs), these effects are usually mild.
EGFR-TKIs are frequently associated with acneiform rash, pruritus, xerosis, and paronychia; however, dAEs associated with third-generation EGFR-TKIs are lower in frequency and severity.
A consensus meeting of a UK-based multidisciplinary panel composed of medical and clinical oncologists with a special interest in lung cancer, dermatologists, gastroenterologists, lung cancer nurse specialists and oncology pharmacists was held to develop guidelines on prevention and management of cutaneous (rash, dry skin and paronychia) and GI (diarrhoea, stomatitis and mucositis) AEs associated with the administration of EGFR-TKIs.
