Topical Pracaxi Oil Base for Scar and Wound Therapy
The objective of a case series by Banov et al. was to evaluate the utility of fatty acids found in pracaxi oil for wound and scar therapy. Initially, 21 patients with various surgical, traumatic, or burn wounds and scars were enrolled. A topical anhydrous silicone base containing pracaxi oil was applied alone, or was compounded to include one or more additional medications tailored to the specific needs of each patient, such as 1% pentoxifylline, 1% caffeine, 1% tranilast, or 2% mupirocin. Patients were advised to apply the compounded topical medication to new or existing scar or wound areas by lightly massaging the compound into and around the scar or wound. The recommended application frequency was two to four times daily based on the attributes of the scar or wound. The mean duration of application of the compounded topical anhydrous base containing pracaxi oil was 11 days and ranged from 48 hours to 3 weeks based on the size and severity of the wound or scar.
The study found that the application of a compounded anhydrous silicone base containing pracaxi oil alone or in combination with other active substances led to considerable improvements in wound healing and scar attributes and is a potentially useful option in the treatment of burns or surgical, or traumatic wounds and scars.

Topical Sildenafil: Potential Benefits for Wound Healing
A clinical study evaluated the effects of topical sildenafil on Pressure ulcer (PrU)-related healing in human subjects. Enrolled patients were randomly allocated to receive topical sildenafil (10%) ointment or placebo daily. Wound healing was assessed visually and photographically by the change in wound score according to two-digit Stirling scale. Decreases in grades of the PrUs were significantly higher in sildenafil group compared with placebo group. In addition, surface areas of ulcers in sildenafil group were significantly reduced compared to the control group at day 14 of intervention. It appears that these effects may be mediated by improvement of microvascular reperfusion in the skin and soft tissue.

Occlusive, Water-Soluble Gel for Wound Management
Polyethylene Glycol (PEG) based occlusive, water-soluble gels specifically formulated for wound management promote a moist environment allowing for optimal healing. These gels contain organic Meadowsweet Extract with phenolic glycosides and flavonoids that potentially provide germicidal, anti-inflammatory and healing properties along with the ability to deliver Active Pharmaceutical Ingredients (APIs) topically to sensitive wound sites.
Benefits:
• Adherent
• Occlusive
• Water-washable allowing for easy cleaning and debridement
• Maintains a moist wound site
Ideal for:
• Wounds
• Diabetic skin ulcers, insufficiency (stasis) ulcers, stage I-IV pressure ulcers
• First and second degree burns
• Post-surgical incisions
• Cuts & Abrasions
• Dermatological applications where a water-washable base would be of benefit
A moist wound environment allows the possibility of increased macrophage and fibroblast activity, re-epithelialization and the production of collagen, and decreased pain. Water washable bases are very important in wound care since wounds need to be cleaned/debrided on a regular basis. Ointments that are not water soluble can disrupt the healing process when the wound is cleaned.
NOTE: Polyethylene glycol (PEG) based vehicles should not be used where absorption of large quantities of polyethylene glycol is possible, such as on extensive burn areas and large surface areas, particularly in patients with moderate or severe renal impairment.
Topical Insulin Accelerates Re-epithelialization
Insulin, when topically applied to wounds, accelerates re-epithelialization and stimulates maturation of the healing tissue, and has significant potential for the treatment of chronic wounds in which re-epithelialization is impaired. Because of its long history of safe use in humans for decades, insulin may prove to be a powerful therapy without major adverse effects.
The study strongly suggests that insulin improves wound healing through an integrated effect not only on re-epithelialization but also on the underlying granulation tissue. Compared with other growth factors used to promote wound repair, insulin treatment is likely to be much less expensive and more readily available. When choosing a concentration of insulin for wound therapy, it is important to determine a dose that does alter blood glucose levels in vivo.

A randomized control study in India evaluated the effect of topical phenytoin on healing in diabetic foot ulcers. One hundred patients with grade I/II diabetic foot ulcers were randomly divided into two equal groups with the study group treated with topical phenytoin dressings and the control group receiving normal saline wound dressings. Discharge and slough from wound reduced significantly by day 14 in phenytoin group and within 21 days in control group. Mean duration of hospital stay in phenytoin group was 20 days, whereas in control group, it was 26 days.

Decubitus Ulcers; Venous Stasis and Diabetic Ulcers; Traumatic Wounds; Skin Autograft Donor Sites; and Burns
Phenytoin has been used topically to speed the healing of decubitus ulcers, pressure sores, venous stasis and diabetic ulcers, traumatic wounds, skin autograft donor sites, and burns. Ketoprofen may be used to control inflammation and pain, lidocaine provides topical anesthesia, and pentoxifylline may improve microcirculation at the wound margins and promote healing of the injured area. Misoprostol, a prostaglandin analog, is often included in wound care formulations to promote healing. Debridement of necrotic eschar with 40% urea paste may also speed healing. Medications which improve capillary blood flow can be added to a compounded medication to enhance circulation at the wound margins and promote healing of the injured area.
Topical Phenytoin for Wound Healing
The stimulatory effect of orally administered phenytoin on gingival tissue prompted its assessment in wound healing. Phenytoin may promote wound healing by a number of mechanisms, including stimulation of fibroblast proliferation, facilitation of collagen deposition, glucocorticoid antagonism, and antibacterial activity. Phenytoin has been used topically in the healing of pressure sores, venous stasis and diabetic ulcers, traumatic wounds, skin autograft donor sites, and burns.
Rhodes et al compared the healing of stage II decubitus ulcers with topically applied phenytoin and two other standard topical treatment procedures in 47 patients in a long-term care setting. Ulcers were examined for the presence of healthy granulation tissue, reduction in surface dimensions, and time to healing. Topical phenytoin therapy resulted in a shorter time to complete healing and formation of granulation tissue when compared with DuoDerm dressings or triple antibiotic ointment applications. The mean time to healing in the phenytoin group was 35.3 +/- 14.3 days compared with 51.8 +/- 19.6 and 53.8 +/- 8.5 days for the DuoDerm and triple antibiotic ointment groups, respectively. Healthy granulation tissue in the phenytoin group appeared within 2 to 7 days in all subjects, compared to 6 to 21 days in the standard treatment groups. The phenytoin-treated group showed no detectable serum phenytoin concentrations.
Anstead et al. described a patient with a massive grade IV pressure ulcer that was unresponsive to conventional treatment, yet responded rapidly to treatment with topical phenytoin. Song and Cheng reported phenytoin improved wound breaking strength in normal and radiation-impaired wounds. The results of their study indicated that topical phenytoin accelerated normal and irradiation-impaired wound healing by increasing the number of wound macrophages and improving the macrophage function. Pendse et al evaluated the effectiveness of topical phenytoin in healing chronic skin ulcers in a controlled trial of 75 inpatients. At the end of the fourth week, 29 of 40 phenytoin-treated ulcers had healed completely versus 10 of 35 controls. They concluded: "topical phenytoin appears to be an effective, inexpensive, and widely available therapeutic agent in wound healing."
The effectiveness of topical phenytoin as a wound healing agent was compared with that of OpSite and a conventional topical antibiotic dressing (Soframycin) in a controlled study of 60 patients with partial-thickness skin autograft donor sites on the lower extremities. Mean pain scores were lower and mean time to complete healing (complete epithelialization) was best in the phenytoin-treated group (6.2 +/- 1.6 days). Topical phenytoin compared very favorably with, and in some aspects was superior to, occlusive dressings.
The efficacy of topical phenytoin in the treatment of diabetic foot ulcers was evaluated in a controlled inpatient study. Fifty patients were treated with topical phenytoin, and 50 patients received dry sterile occlusive dressings. Both groups improved, but the ulcers treated with topical phenytoin healed more rapidly. Mean time to complete healing was 21 days with phenytoin and 45 days with control.
No study reported any significant adverse effects secondary to topical phenytoin therapy.

Benzoyl Peroxide for Treatment of Decubitus Ulcers
Benzoyl peroxide is a powerful oxidizing agent with broad spectrum germicidal activity and good liposolubility. Therefore, it may represent a good agent for prevention of wound infection in areas with high density of sebaceous glands. Topical treatment of pressure sore with 20% benzoyl peroxide in O/W emulsion yielded very satisfactory results. In another study, 10% benzoyl peroxide gel was used prophylactically once a day for 7 days before surgery. The researchers concluded that topical benzoyl peroxide is an efficacious, harmless, and inexpensive agent for prevention of wound infections in seborrheic regions.
