Chapter 56: Dermatological Drugs – Skin Treatments & Wound Care

The chapter thoroughly classifies various common skin disorders, including bacterial infections like folliculitis and impetigo, fungal conditions such as tinea (ringworm) and candidiasis, inflammatory states like psoriasis and dermatitis, and parasitic infestations like pediculosis (lice) and scabies. A major focus is placed on topical dermatological drugs, outlining their diverse formulations—including occlusive ointments, water-based creams, and penetrating gels—and their therapeutic categories, such as antimicrobials (e.g., bacitracin, mupirocin), antiacne agents (e.g., benzoyl peroxide, tretinoin), powerful corticosteroids used for anti-inflammatory and antipruritic relief, and specific antineoplastic drugs like fluorouracil. Critical emphasis is placed on highly potent medications, such as the oral retinoid isotretinoin, highlighting its strict contraindication during pregnancy due to its teratogenic risk and the need for rigorous risk management programs. Finally, the nursing process for administering these drugs is detailed, stressing crucial steps like comprehensive skin assessment, adherence to proper application techniques (using gloves and thin layers), patient education regarding photosensitivity, managing adverse effects, and understanding potential systemic absorption, particularly in young children or when treating large surface areas.
