Desoximetasone: A Breakthrough Treatment for Eczema

What Is Desoximetasone?

Desoximetasone is an effective medicine that helps in managing conditions like eczema. Eczema can make the skin cracked, rough, scaly, and very itchy. The United States Food and Drug Administration (FDA) has approved the use of Desoximetasone for eczema. This medicine is sold in different forms and with different brand names. Desoximetasone can also help with other skin problems, not just eczema.

Is Desoximetasone Approved by the FDA?

Desoximetasone was approved by the FDA (Food and Drug Administration) in 1977 for the topical treatment of skin conditions such as psoriasis and eczema.

Drug Group:

Desoximetasone falls under the primary synthetic corticosteroid drug class. These corticosteroids elicit functions that mimic those of one of the hormones secreted by the adrenal gland, called cortisol. The corticosteroid drug class is known for its potent anti-inflammatory activity, which helps resolve active inflammatory conditions in the body.

Available Doses and Dosage Forms:

• Dosage Forms: Desoximetasone is specifically indicated for topical use, and therefore, it is formulated and marketed in four distinct forms: gel, cream, spray, and ointment.

• Available Doses: Formulations contain concentrations ranging from 0.05 to 0.25 percent. Gels, creams, and ointments are available in 0.05 percent concentration, in which a single gram of the formulation contains 0.5 milligrams of Desoximetasone. 0.25 percent Desoximetasone is generally marketed in spray form, in which a single gram of spray formulation contributes 2.5 milligrams of active drug molecules.

For Patients:

How Does Desoximetasone Work?

Desoximetasone works for eczema by reducing inflammation and other troubling manifestations. The mechanism by which Desoximetasone works for eczema needs to be clarified and made more specific. As a corticosteroid, Desoximetasone is known to trigger the production of an inhibitory protein that can inhibit the synthesis of bodily substances that facilitate inflammation. Those substances are referred to as inflammatory mediators that enhance the inflammatory response by eliciting symptoms such as swelling, soreness, itching, and more.

What Is the Dosage of Desoximetasone?

Desoximetasone's topical composition in cream, gel, and ointment is marketed in a 0.05 percent concentration. Being a topical formulation, it has to be applied to the affected skin area as a thin film twice daily. It is the most widely preferred dosage of Desoximetasone for tackling eczema.

How Effective Is Desoximetasone?

The efficacy and potency of Desoximetasone have been evaluated in various clinical trials, in which it was tested in subjects with eczema. The trial results were on par with those of other standard eczema treatments. Desoximetasone alleviated symptoms such as itching and skin cracking. In addition to eczema, it has demonstrated efficacy in treating other skin issues, including rashes, blisters, and skin bumps.

What Are the Things to Inform the Doctor Before Taking the Drug?

Before using Desoximetasone, it is important to tell your doctor some important things. This helps the doctor make sure the medicine is safe for you.

• Tell your doctor if you have ever had an allergy to Desoximetasone or other corticosteroid medicines.

• Inform your doctor about all your past and present health problems. Conditions like high blood sugar (diabetes) or Cushing’s syndrome can increase the risk of side effects.

• Tell your doctor about all medicines you are taking. This includes prescription, over-the-counter, and herbal products, as well as vitamins and supplements. This helps prevent harmful drug interactions.

• Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding. Some medicines may affect the baby, so your doctor will decide if it is safe.

How Is Desoximetasone Administered?

Desoximetasone is available in formulations that can be applied to the skin. These formulations are not intended for oral intake.

• Take out an appropriate amount of the formulation (gel, cream, or ointment) onto the fingertip, then gently apply it to the affected area and stroke it in.

• Vigorous rubbing can further damage eczematous skin, so care should be taken to ensure the medicine is evenly coated.

• Only a thin film of the medicine must be coated over the skin. Over-application of Desoximetasone can worsen side effects, while under-application can significantly reduce effectiveness.

• After application, the hands should be washed immediately to assess the uptake of the topical formulations.

• While applying Desoximetasone, care should be taken not to allow the medicine to come into contact with the mouth, eyes, or other private parts where it is not intended to be applied.

• After application, the treated area should be left open unless the concerned doctor advises otherwise. Protecting the skin area with an occlusive dressing can enhance the medicine's uptake into the bloodstream, leading to toxicity.

What Are the Side Effects of Desoximetasone?

Desoximetasone is usually safe when used as directed. However, some people may experience side effects, especially with long-term use.

• Allergic Reactions: Patients undergoing Desoximetasone topical therapy often report sudden skin irritation, intense itching, and a burning sensation with pain and heat over the treated area.

• Hair Growth: Unusual hair growth may occur in the area where the medicine is applied.

• Acneiform Eruptions: The development of acne and other skin bumps is another potential side effect manifested following topical therapy.

• Eczema Breakouts: Though Desoximetasone is advised for treating eczema manifestations, at times the topical formulation itself can trigger eczema, leading to sudden worsening of eczematous reactions. Dryness and a prickling sensation worsen the condition.

• Perioral Dermatitis: Numerous small pinpoint bumps encircling the mouth are also reported following topical Desoximetasone therapy.

• Hypopigmentation: The skin loses its natural color following long-term topical therapy using Desoximetasone. Skin patches with compromised coloration that stand out from the surrounding skin create aesthetic concern for the patient.

• Grave Reactions: Extensive skin rashes with bleeding areas rarely occur with Desoximetasone. Pus-releasing points and bleeding points are indications of severe skin reactions underneath, which entail immediate medical attention.

Dietary Considerations:

No specific dietary instruction must be followed while undergoing Desoximetasone topical therapy. However, each patient's medical condition and health status differ, and the doctors analyze each case individually. The patient will be advised to follow certain dietary instructions to support treatment in such cases.

Missed Dose:

• The topical formulations are generally advised to be applied twice daily.

• It is better to follow a specific application period throughout the treatment.

• However, at times, the patient may need to remember to apply at the specified time; in such cases, it is advised to apply once the patient becomes aware of the missed dose.

• If the patient recalls it only at the time of subsequent application, it is best to skip the missed dose.

• Never apply additional topical formulations to compensate for an overlooked dose, as this can lead to adverse side effects.

Overdose:

• Since Desoximetasone is made available in topical formulations, overdose issues can arise with either over-application or frequent application of the medicine.

• Overdosing can increase the risk of skin adverse reactions.

• It can bring severe burning and prickling sensations to the skin.

• Oral intake of the topical formulation can also bring in potential overdose issues and other systemic complications.

• In such cases, immediate medical care should be made available to the patient to tackle the overdose issues.

Storage:

• Room temperature is ideal for cream, gel, and ointment formulations of Desoximetasone.

• At the same time, the spray formulation of Desoximetasone should be kept within the temperature range of 20 to 25 degrees Celsius (68 to 77 degrees Fahrenheit).

• All these topical formulations should be protected from exposure to heat, particularly the spray form, as it can catch fire easily.

• These formulations should be made inaccessible to small kids to check inadvertent ingestion or application of the medicine.

• Medicines beyond the expiration date should be disposed of as advised by the pharmacist or the medical professional.

For Doctors:

Indications:

• Eczema.

• Psoriasis (plaque type).

• Inflammatory dermatoses.

• Pruritic dermatoses.

Dosing Considerations:

To keep the dosage consistent, a specific time for the topical application of Desoximetasone is always instructed. This ensures that drug concentration in the blood remains consistent throughout the treatment course, thereby ensuring the availability of the medicine at the required concentration.

What Are the Pharmacological Aspects of Desoximetasone?

Mechanism:

• The mechanism behind the action of Desoximetasone is more or less similar to that of other corticosteroids.

• Desoximetasone exerts its actions through specific properties, such as anti-pruritic, vasoconstrictive, and anti-inflammatory.

• Once Desoximetasone reaches the cellular cytoplasm, it interacts with the cytoplasmic receptor proteins. This interaction results in a steroid-receptor complex that associates with the genetic material in the cellular nucleus. This complex alters transcription, thereby enhancing lipocortin production.

• The lipocortin glycoprotein can influence the function of the enzyme phospholipase A2.

• Major mediators of inflammation are triggered and activated by the enzyme arachidonic acid. Phospholipase A2 is imperative for arachidonic acid formation.

• The enhanced production of lipocortin inhibits phospholipase A2.

• Once there is a potent inhibition of phospholipase A2, it is reflected in reduced arachidonic acid formation. Thereby eliciting anti-inflammatory actions.

Pharmacodynamics:

Desoximetasone also inhibits interleukin-1 production by binding to the corresponding messenger RNA (mRNA). It enhances the immunosuppression and anti-inflammatory properties.

Pharmacokinetics:

• Once Desoximetasone comes into contact with the skin surface, it is taken up by the cells.

• The rate of uptake is often guided by factors such as the integrity of the skin, the vehicle of the topical formulation, the type of topical formulation, and the occlusive dressing on the skin surface.

• Desoximetasone appreciably penetrates the inflamed skin and reaches the systemic circulation.

• The distribution of the drug is aided by plasma proteins that form complexes.

• Certain liver enzymes are responsible for the metabolism and breakdown of the Desoximetasone drug molecules, while the elimination occurs through the kidneys. However, biliary excretion is also reported with certain corticosteroids.

Toxicity:

• Numerous non-clinical studies were conducted to assess the toxicities associated with the use of topical formulations of Desoximetasone.

• However, none of the animal studies could establish any mutagenic potential for Desoximetasone.

• A 13-week animal study with topical Desoximetasone concluded the medicine's potential to precipitate severe immunosuppression and adrenal atrophy.

• Therefore, long-term exposure to Desoximetasone is likely to influence carcinogenesis.

• Non-clinical studies failed to demonstrate a safer dose of Desoximetasone with no side effects.

Clinical Studies:

Randomized clinical trials were conducted to evaluate and demonstrate the potency of Desoximetasone in tackling eczema. It was concluded that subjects treated with Desoximetasone exhibited a significant reduction in pruritus compared with other standard topical eczema treatments. In addition, various post-marketing surveillance studies have validated the efficacy and safety of topical Desoximetasone.

What Are the Contraindications of Desoximetasone?

There are no reports of absolute contraindications for the topical formulation of Desoximetasone. However, patients with a history of hypersensitivity or exaggerated reactivity towards Desoximetasone or any other topical corticosteroid medications are advised to refrain from using Desoximetasone in any form. Similarly, patients with allergic reactions to any of the components in the topical formulations of Desoximetasone are advised not to use the medicine.

Warnings and Precautions:

• Glucocorticosteroid Insufficiency: Desoximetasone may suppress the HPA (hypothalamic-pituitary-adrenal) axis, leading to manifestations of glucocorticosteroid insufficiency. The risk is higher at the beginning and end of treatment. Patients with diabetes or Cushing’s syndrome have a higher risk. Regular check-ups may be needed during treatment.

• Allergic Contact Dermatitis: Some people may develop an allergic skin reaction to Desoximetasone. This can cause redness, itching, and rash. If this happens, stop using the medicine and inform your doctor.

• Local Skin Reactions: Desoximetasone may cause local skin reactions. Some widely reported local reactions include acneiform eruptions, telangiectasias, perioral dermatitis, folliculitis, atrophy, and hypopigmentation.

• Secondary Infections: Using Desoximetasone for a long time can weaken the skin’s defense. This may increase the risk of infections. If the infection does not improve, your doctor may stop the medicine.

• Occlusal Dressing: Do not cover the treated area with bandages or tight dressings unless your doctor tells you to. Covering the area can increase the amount of medicine absorbed into the body and increase side effects.

What Are the Drug Interactions of Desoximetasone?

Simultaneous use of certain medicines can precipitate adverse reactions. At times, such interactions may influence the efficacy of one or both medicines. Simultaneous use of Desoximetasone's topical formulation and another topical formulation of the same class (corticosteroid) is not advisable, as it can increase systemic exposure to corticosteroids. It can bring in various side effects and, at times, can result in toxicity issues.

Topical corticosteroid formulations of Triamcinolone, Prednisone, and Betamethasone are widely reported to have significant interactions with Desoximetasone, leading to unwanted and adverse effects. Hence, patients should be instructed not to combine different eczema medicines. Before using any other medicines while undergoing therapy using Desoximetasone, it is better to seek expert advice from specialist doctors to ensure the safety and effectiveness of the combination.

Specific Considerations:

• Desoximetasone During Pregnancy: Desoximetasone is generally not recommended during pregnancy. It falls into category C of pregnancy medications. Animal studies have shown harm to the unborn baby at high doses. There is no clear proof in humans, but it should be used only if the doctor advises it.

• Desoximetasone During Lactation: It is not known if Desoximetasone passes into breast milk when applied to the skin. However, there may be a risk to the baby. Breastfeeding mothers should use this medicine only if prescribed by a doctor.

• Desoximetasone in the Pediatric Population: There is insufficient information on the safety of Desoximetasone in children under 18 years. Children may have a higher risk of side effects. Therefore, it should be used in children only under medical supervision.

• Desoximetasone in the Geriatric Population: Older adults usually tolerate Desoximetasone well. However, extra care is needed because they may have kidney, liver, or heart problems or other health conditions.
