Everyone’s skin is different – skincare solutions should be too. Compounding has long been recognized as a productive treatment avenue for addressing skin. Our pharmacy can formulate several new solutions designed to help make a difference for your individual skin challenges. We also carry our own skincare line. Ask about our RX Formulations products.

Per a prescription order, a formulatio`11n can be compounded to contain the proper combination of active ingredients, in the most appropriate base, to treat a specific type of wound. We customize medications to meet each individual’s specific needs.

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.

In the following study, the effects of topical 0.01% estradiol and 0.3% estriol compounds were measured in preclimacteric women with skin aging symptoms. After treatment for 6 months, elasticity and firmness of the skin had markedly improved; wrinkle depth and pore sizes had decreased by 61 to 100%; skin moisture had increased; and wrinkle depth decreased significantly.

Abnormal dermal scarring which affects a large number of people is aesthetically disfiguring and can be functionally disabling. Existing medical and surgical strategies to prevent or to treat scars are frequently disappointing and more effective therapies are needed. Tamoxifen, which has been used extensively in the treatment of breast cancer over the last 20 years has recently been shown to inhibit the proliferation of fibroblasts cultured from keloid biopsies. Successful treatment of retroperitoneal fibrosis and desmoid tumours with tamoxifen has also been reported. We have investigated the potential of tamoxifen as an inhibitor of wound contraction, using fibroblast-populated collagen lattices as an in vitro model.

From these studies we postulate that tamoxifen may have potential clinical significance in the treatment of abnormal scarring. Normal adult human skin fibroblasts were embedded within type I collagen, then medium either with or without addition of tamoxifen was added to the collagen lattices. Lattice diameters were measured at intervals to assess the influence of tamoxifen on the lattice contraction. The reversibility of the inhibitory effect of tamoxifen on lattice contraction was investigated by ‘washing out the tamoxifen’ at different time-points. To visualise changes in the morphology of fibroblasts MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide] was added to the lattices. Tamoxifen at 1 and 5 microM had no significant influence on lattice contraction but higher concentrations of 50 and 100 microM completely inhibited contraction. At intermediate concentrations from 10 to 20 microM the degree of lattice contraction was dose-dependent. The reversibility of the inhibition was both dose- and time-dependent. Both the inhibition of contraction and the reversibility of inhibition appeared to correlate with changes in fibroblast morphology.

The dose- and time-dependent inhibition of contraction by fibroblasts suggests that tamoxifen could be investigated as a novel potential therapeutic agent in treating abnormal dermal scarring.

Topical anesthesia is needed for common procedures such as suturing, wound cleaning, and injection administration. The ideal topical anesthetic would provide complete anesthesia following a simple pain-free application, not contain narcotics or controlled substances, and have an excellent safety profile.  The combination of topical anesthetics lidocaine and tetracaine and the vasoconstrictor epinephrine has been used successfully for anesthesia prior to suturing linear scalp and facial lacerations in children. A triple-anesthetic gel containing benzocaine, lidocaine, and tetracaine (“BLT”) has also been reported to be effective when applied prior to laser and cosmetic procedures. Convenience of application without need for occlusion is an advantage of these topical anesthetics.

The following article concludes: “LAT gel (4% lidocaine, 1:2000 adrenaline, 0.5% tetracaine) worked as well as TAC gel (0.5% tetracaine, 1:2000 adrenaline, 11.8% cocaine) for topical anesthesia in facial and scalp lacerations. Considering the advantages of a noncontrolled substance and less expense, LAT gel appears to be better suited than TAC gel for topical anesthesia in laceration repair in children.”

The following article reported that a triple-anesthetic gel containing benzocaine, lidocaine, and tetracaine (“BLT”) applied prior to treatment with a 532-nm KTP laser resulted in significantly lower pain scores than with 3 other topical anesthetics at 15, 30, 45, and 60 minutes after application.

Rosacea is a very common skin disease that affects people over the age of 30. It causes redness on your nose, cheeks, chin, and forehead. Some people get little bumps and pimples on the red parts of their faces. Rosacea can also cause burning and soreness in your eyes.

The following article stated: “among many important physiological functions played by NADH (the reduced form of beta-nicotinamide adenine dinucleotide) its antioxidative properties are remarkable. Acting directly as an antioxidant, NADH can effectively protect the cell and its membrane from destruction by free radicals. NADH can be stabilized as a suspension in hydrophobic ointments prepared in a way that prevents contact with atmosphere containing oxygen and water. We present the first report of NADH as a treatment for some inflammatory dermatoses. It was found that topical application of 1% NADH diluted in Vaseline ointment can be very effective in the treatment of rosacea and contact dermatitis. Since no adverse effects were observed, therapy with NADH can be viewed as a potential alternative to other established treatments.”

Plantar warts and Palmer warts are common, especially in children. These warts are named for where they appear on the body. Palmer warts occur on the hands, and plantar warts on the bottom of the foot.

Virtually everyone will have a wart (or several) someplace at some time in their lives.

Plantar warts and palmer warts are noncancerous skin growths, caused by a viral infection in the top layer of the skin. The culprit is a strain of virus called human papillomavirus or HPV. Many strains of the virus exist, and those that cause common warts on the hands and feet are not the same strains of HPV that cause genital warts.

The following article concluded: “sodium salicylate iontophoresis appeared to compare favorably with other office-based interventions in diminishing the size of plantar warts and their associated pain. Application of iontophoresis to weight-bearing surfaces in some subjects appeared to decrease the pain and scarring associated with freezing and electrocautery and the fixation problems associated with medicated patches.”

Management of onychomycosis, a fungal infection of the fingernails and toenails, usually consists of systemic antifungal medications, topical therapy (e.g., urea ointment, desiccating solutions, keratolytics, vital dyes), or surgical intervention (e.g., nail plate avulsion, laser therapy). Topical prescription antifungal preparations, containing the active ingredient of your choice, may be less likely to cause the serious systemic side effects that can occur with oral antifungal therapy and can provide a more economical alternative, as lower doses are needed when the medication is applied topically at the site. Penetrant enhancers can be included in the preparation to improve the effectiveness of topical antifungals.

Although surgical excision is the most popular method for removing nails, the use of concentrated urea plasters applied under occlusion may be superior. The use of urea plasters has inherent advantages – they are inexpensive, several nails can be treated in one session, and the procedure is essentially painless. Various synergistic combinations and topical medications with penetrant enhancers can be compounded for antifungal therapy. Topical medications usually have a lower adverse drug-reaction profile than systemic medications.
