For example, the choice of cream, ointment, or gel can be clinically significant. Each time a wound needs to be cleaned, there is the potential for disruption of new tissue growth. Gels, which are more water soluble than creams or ointments, may be preferable for wound use because a gel can be rinsed from the wound by irrigation. Ointments may contain polyethylene glycol (PEG), which can be absorbed from open wounds and damaged skin. If the wound is quite large and too much PEG is absorbed, it can lead to renal toxicity.
Another useful dosage form is the "polyox bandage" - which can be puffed onto a wound and will adhere even if exudate is present. A polyox bandage can be compounded to contain the active ingredient(s) of your choice.
