Calcitriol is a synthetic derivative of the active metabolite of vitamin D. It is primarily used in the treatment of various skin conditions. As a topical treatment, it is specifically indicated for use in conditions like psoriasis where it helps regulate abnormal skin cell growth.
Calcitriol (topical) is often prescribed when other treatments have failed or when a more localized treatment is required. Its unique properties make it one of the key drugs in controlling chronic dermatological conditions that are mainly linked to the overproduction of skin cells.
Using calcitriol topical is not a very complicated process, but it does require careful adherence to instructions to ensure maximum effectiveness while minimizing the risk of side effects. Here are the steps typically involved in using calcitriol:
Clean the Affected Area: Before applying the medication, wash and gently dry the affected skin areas. This helps to ensure that the skin is clean, which can improve the absorption of the drug.
Use just a thin layer: One or two grams of the ointment or cream must be placed onto the affected area of skin. Do not use an excess amount, as thicker layers do not guarantee an effective result.
Massage Gently: Massage the calcitriol into your skin until it is well absorbed. Never apply any form of this medication over damaged, inflamed, or infected skin because of possible reactions.
Avoid Sensitive Areas: Be cautious when applying calcitriol near sensitive areas like the face, groin, or armpits unless directed by a healthcare provider.
Wash Hands After Application: After applying the medication, wash your hands thoroughly to avoid transferring the drug to other parts of the body, particularly sensitive areas like the eyes.
The mechanism of action of calcitriol is linked to regulating gene expression through interaction with a vitamin D receptor (VDR). Interaction of calcitriol with skin cells VDRs determines the expression and production of proteins that take part in cell differentiation, proliferation, and apoptosis, or the process of programed death. By binding to the VDR, calcitriol promotes normalization of the cell cycle in skin cells, reducing excessive production and turnover of cells responsible for the thick, scaly lesions characteristic of psoriasis.
This happens, more specifically, by counteracting excessive production of keratinocytes-the outermost layer’s skin cells. In cases of psoriasis, it triggers over proliferation and leads to abnormal build-ups on the skins and this process calcitriol retards while inducing some level of antiinflammatory response. It’s very mildly immunosuppressive hence further contributing to the alleviation of inflammation in diseases such as these.
While calcitriol topical is generally well tolerated, any medication can cause side effects.
Skin Irritation: The most common side effect is mild irritation at the application site. This may include redness, itching, or a burning sensation.
Photosensitivity: Calcitriol may cause the skin to become more sensitive to sun exposure, leading to phototoxicity and potential sunburn. Patients should avoid prolonged sunlight exposure or apply sunscreen to all treated areas.
Hypercalcemia (Rare): Occasionally, excessive topical calcitriol use can lead to hypercalcemia, a clinical condition characterized by elevated circulating calcium levels. Symptoms can include nausea, vomiting, confusion, or fatigue.
Allergic Reactions: In extremely rare cases, the users may experience allergic reaction which can be rash, swelling, or difficulty in breathing. It is a case requiring immediate medical attention.
Overuse: Topical calcitriol should not be applied to extensive areas of the skin for a long period as this increases the chances of systemic absorption that can cause hypercalcemia.
Avoid Contact with Eyes: Avoid contact of calcitriol around the eyes, nose, mouth, and mucous membranes. In case of contact, flush thoroughly with water.
Pregnancy and Breastfeeding: Although topical calcitriol poses less risk, a consultation with a doctor is essential before its use during pregnancy or breastfeeding.
Avoid Use on Broken Skin: Calcitriol should not be applied to broken, irritated, or infected skin as it may worsen these conditions or increase the risk of systemic absorption.
Sun Exposure: Since calcitriol can increase the skin’s sensitivity to sunlight, it is essential to protect treated areas from direct sunlight or use a sunscreen with high SPF.
Topical Corticosteroids: The combination of calcitriol (topical) and corticosteroids (e.g., hydrocortisone) used on the same area of skin may enhance the absorption of both medications. This could increase the risk of side effects like skin thinning or systemic effects due to increased absorption.
Calcium Supplements: Calcitriol increases calcium absorption from the gut, and when combined with calcium supplements (e.g., Calcium 500 + D), it may lead to hypercalcemia (elevated calcium levels). Monitoring calcium levels is important to avoid potential complications.
Thiazide Diuretics: When used with thiazide diuretics (e.g., hydrochlorothiazide), calcitriol may increase the risk of hypercalcemia due to both its effect on calcium absorption and thiazides’ tendency to retain calcium. Careful monitoring of blood calcium levels is recommended.
Phenytoin and Barbiturates: Medications like phenytoin and barbiturates may increase the metabolism of vitamin D, including calcitriol, potentially reducing its effectiveness. This could lead to insufficient calcium absorption and lower serum calcium levels.
The typical dosage for topical calcitriol is as follows:
Initial Dose: Use the thin layer of calcitriol cream or ointment once or twice a day on the affected areas of the skin.
Maintenance Dose: Your physician will adjust the frequency depending on the response to the treatment and any side effects that may occur. Some may reduce the frequency of the application to once per day, while others may have the treatment applied only several times a week for maintenance purposes.
It is also important to take the recommended dosage and schedule given by your physician. If you miss a dose, apply the medication as soon as you remember, except if it is nearly time for your next dose. You should not apply extra medication to make up for the missed doses.
Calcitriol is available only by prescription, and a doctor will determine if this is appropriate based on the patient’s skin condition and medical history. The doctor will evaluate the severity of the condition and possible contraindications, such as allergies or other medical conditions, before prescribing.
The patients should closely follow the prescription guidelines and report any changes in symptoms or side effects to the healthcare provider promptly.
Topical calcitriol is a prescription medication that contains calcitriol, the active form of vitamin D3, and is used to treat skin conditions like psoriasis.
Topical calcitriol works by slowing the growth of skin cells and reducing inflammation, which helps to alleviate the symptoms of conditions like psoriasis.
Topical calcitriol is primarily used to treat plaque psoriasis and other related skin disorders.
Topical calcitriol is applied directly to the affected skin areas, typically twice daily, as directed by a healthcare provider.
Common side effects may include skin irritation, itching, burning sensation, redness, and rash at the application site.
