Soritene
Soritene Uses, Dosage, Side Effects, Food Interaction and all others data.
Soritene is a retinoid prodrug which is converted to its active form, the cognate carboxylic acid of tazarotene, by rapid deesterification in animals and man. In cell culture and in vitro models of skin, tazarotene suppresses expression of MRP8, a marker of inflammation present in the epidermis of psoriasis patients at high levels. In human keratinocyte cultures, it inhibits cornified envelope formation, whose build-up is an element of the psoriatic scale.
Following topical application, tazarotene undergoes esterase hydrolysis to form its active metabolite, tazarotenic acid. When treating acne tazarotene may be taken in conjunction with an oral antibiotic. Soritene has been shown in peer-reviewed double blinded studies to reduce: mottling and hyperpigmentation, sallowness, fine wrinkling and coarse wrinkling in sun damaged skin. Histological studies have shown that long term (greater than 1 year) use of Soritene is associated with a significant reduction in atypical melanocytes and keratocytes - cells considered to be precursors of skin cancer. Some studies have shown long term use of Soritene to be associated with increased collagen production and better organization of skin collagen bundles.

Uses
Soritene is used to treat plaque psoriasis of the skin. It also works to treat acne on the face.
Soritene is also used to associated treatment for these conditions: Psoriasis Vulgaris (Plaque Psoriasis), Benign facial lentigines, Facial fine wrinkling, Facial hyperpigmentation, Facial hypopigmentation, Mild Acne vulgaris, Moderate Acne vulgaris
How Soritene works
Although the exact mechanism of tazarotene action is not known, studies have shown that the active form of the drug (tazarotenic acid) binds to all three members of the retinoic acid receptor (RAR) family: RARa, RARb, and RARg, but shows relative selectivity for RARb, and RARg and may modify gene expression. It also has affinity for RXR receptors.
Dosage
Soritene dosage
For psoriasis: Soritene cream should be applied once per day, in the evening, to psoriatic lesions, using enough (2 mg/cm2) to cover only the lesion with a thin film. If a bath or shower is taken prior to application, the skin should be dried before applying the cream. If emollients are used, they should be applied at least one hour before application of Soritene cream.
For acne: Cleanse the face gently. After the skin is dry, apply a thin layer (2mg/cm2) of Soritene cream 0.1% once per day, in the evening, to the skin areas where acne lesions appear. Use enough to cover the entire affected area.
Side Effects
The most frequent adverse events reported with Soritene cream were limited to the skin. Those occurring in 10 to 23% of patients, in descending order, included pruritus, erythema and burning. For acne treatment, in 10 to 30% patients, it is reported desquamation, dry skin, face pain, irritation and stinging sensation.
Toxicity
Excessive topical use may lead to marked redness, peeling, or discomfort. Oral ingestion of the drug may affect liver function causing hypertriglyceridemia. Other symptoms may include conjunctival irritation, hair loss, headache, edema, fatigue, dermatitis, nausea, and visual disturbances. Oral administration of this material to rats and rabbits at doses of 0.20 mg/kg/day (rabbits) and 0.25 mg/kg/day (rats) resulted in developmental toxicity. A no effect level of 0.05 mg/kg/day was established. Similar teratogenic effects have been reported for other retinoid compounds.
Precaution
Soritene cream should be applied only to the affected areas. For external use only. Avoid contact with eyes, eyelids and mouth. If contact with eyes occurs, rinse thoroughly with water. Retinoids should not be used on eczematous skin, as they may cause severe irritation. Patients must be warned to use sunscreens and protective clothing when using Soritene cream. Some individuals may experience excessive pruritus, burning, skin redness or peeling. If these effects occur, the medication should either be discontinued until the integrity of the skin is restored, or the dosing should be reduced
Interaction
Concomitant dermatologic medications and cosmetics that have a strong drying effect should be avoided. It is also advisable to "rest" a patient’s skin until the effects of such preparations subside before use of Soritene cream is begun. Topical steroid may be hazardous in psoriasis; careful patient supervision is important. Consider if infection spreads. Do not use near a naked flame.
Food Interaction
No interactions found.Elimination Route
Minimal systemic absorption of tazarotene occurs due to its rapid metabolism in the skin to the active metabolite, tazarotenic acid, which can be systemically absorbed and further metabolized. Gender had no influence on the systemic bioavailability of tazarotenic acid.
Half Life
The half-life of the active form of the drug, tazarotenic acid, is approximately 18 hours in normal and psoriatic patients.
Elimination Route
Soritene and tazarotenic acid were metabolized to sulfoxides, sulfones and other polar metabolites which were eliminated through urinary and fecal pathways.
Pregnancy & Breastfeeding use
Pregnancy: Soritene is not recommended during pregnancy. It has been shown to cause serious birth defects and problems in animals. Be sure you have discussed this with your doctor.
Nursing Mothers: It is not known whether tazarotene passes into breast milk. However, Soritene is not recommended during breast-feeding because it may cause unwanted effects in nursing babies.
Contraindication
Retinoids may cause fetal harm when administered to a pregnant woman. Soritene cream is contraindicated in women who are or may become pregnant. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, treatment should be discontinued and the patient should be apprised of the potential hazard to the fetus. Women of childbearing potential should be warned to the potential risk and use adequate birth-control measures when Soritene cream is used.
Special Warning
Pediatric Use: Studies of this medicine have been done only in adult patients, and there is no specific information comparing use of Soritene in children up to 12 years of age (gel) and up to 18 years of age (cream) with use in other age groups.
Elderly Use (Over 65 year): There is no specific information comparing the use of Soritene in the elderly with use in other age groups.
Acute Overdose
Excessive topical use cause marked redness, peeling or discomfort. Accidental oral ingestion produces similar adverse effects as those associated with excessive oral intake of Vitamin A or other retinoids. Monitor and take supportive measures as necessary.
Storage Condition
