What is an example of a growth factor therapy?

1. Becaplermin gel

2. Hydrocolloid dressing

3. Silver sulfadiazine cream

4. Antibiotic ointment

The correct answer is: Becaplermin gel

Becaplermin gel is an example of a growth factor therapy because it contains platelet-derived growth factor (PDGF), which plays a critical role in wound healing. This gel is specifically formulated to promote granulation tissue formation and enhance the healing of chronic ulcers, particularly diabetic foot ulcers. By providing growth factors directly to the wound site, becaplermin gel encourages cell proliferation and migration, leading to improved outcomes in the wound healing process. Its application is particularly beneficial in cases where natural healing processes are impaired, showcasing its targeted approach to enhance tissue repair. Other options, such as hydrocolloid dressings, silver sulfadiazine cream, and antibiotic ointment, serve different purposes in wound management. Hydrocolloid dressings provide moisture retention and protection for wounds but do not directly influence growth factor levels. Silver sulfadiazine cream is an antibacterial treatment primarily intended for preventing or treating infections, especially in burn wounds, rather than promoting growth factor activity. Antibiotic ointments are also focused on infection control, not on stimulating growth factors. Therefore, becaplermin gel stands out as a specific therapeutic agent focused on enhancing the wound healing process through the use of growth factors.
