Tapinor30 gm

Tapinor cream is a non-steroidal topical medicine used for the following skin conditions:

Established / Approved Uses

• Plaque psoriasis (adults): Topical treatment of plaque psoriasis in adult patients.
• Atopic dermatitis (adults and children aged 2 years and older): Topical treatment of mild, moderate, or severe atopic dermatitis (eczema).

Tapinor is not approved for use in children below 2 years of age or for plaque psoriasis in the pediatric population, as safety and efficacy have not been established for these uses.

Tapinor is a first-in-class, non-steroidal topical small-molecule that works as an aryl hydrocarbon receptor (AhR) agonist. It is formulated as a 1% cream for once-daily topical application and is used in the management of plaque psoriasis and atopic dermatitis. As a non-steroidal option, Tapinor does not carry the skin-thinning (atrophy) or hypothalamic-pituitary-adrenal (HPA)-axis suppression risks associated with long-term topical corticosteroid use, although it has its own distinct side-effect profile that patients should be counseled about. Tapinor is available in Bangladesh as a 1% cream under several brand names.

Topical Aryl Hydrocarbon Receptor (AhR) Agonist; non-steroidal topical anti-inflammatory agent for dermatologic use.

Tapinarof is an agonist of the aryl hydrocarbon receptor (AhR), a ligand-activated transcription factor expressed in skin cells. By binding and activating AhR, Tapinarof is thought to help normalize skin barrier function (including upregulation of genes such as filaggrin), reduce production of pro-inflammatory Th17-pathway cytokines (including interleukin-17), and exert antioxidant effects through activation of the NRF2 pathway. The precise mechanism responsible for the clinical benefit of Tapinarof in psoriasis and atopic dermatitis has not been fully established.

Following topical application, systemic absorption of Tapinarof is minimal; plasma concentrations are frequently below the limit of quantification in adults. Tapinarof is highly protein-bound (~99%) and is metabolized via oxidation, glucuronidation, and sulfation. It does not clinically inhibit or induce the major cytochrome P450 (CYP) enzymes at recommended topical doses, and does not prolong the QTc interval.

• For topical (external) use on the skin only. Tapinor is not for oral, ophthalmic (eye), or intravaginal use.
• Apply a thin, even layer of Tapinor cream to the affected skin areas once daily.
• Wash hands with soap and water after application, unless the hands are being treated.
• Avoid contact with the eyes, lips, mouth, and vaginal mucosa; rinse thoroughly with water if accidental contact occurs.
• Do not apply Tapinor under occlusive dressings unless specifically directed by a physician.

No clinically significant systemic drug-drug interactions have been established for Tapinor cream. Laboratory studies show that Tapinor does not clinically inhibit or induce major cytochrome P450 (CYP) enzymes (including CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, and CYP3A4/5) at the systemic exposure levels achieved with topical use, so meaningful drug interactions are considered unlikely.

As a general precaution, avoid applying other topical products (including other medicated creams, strong irritants, or exfoliants) to the same skin area at the same time as Tapinor, since this may increase local skin irritation. Inform the physician or pharmacist of all other topical or systemic medicines being used.

The side-effect profile of Tapinor differs somewhat by indication.

Folliculitis (inflammation of hair follicles) is the most frequently reported local skin reaction with Tapinor and is usually mild to moderate and self-limiting, though it occasionally requires stopping treatment. Contact dermatitis, application-site irritation, and, rarely, urticaria (hives) or other hypersensitivity reactions can also occur. If a severe or worsening skin reaction, or signs of an allergic reaction, develop while using Tapinor, treatment should be stopped and a physician consulted promptly.

Pregnancy: There are limited human data on the use of Tapinor in pregnant women. Animal reproduction studies did not show fetal harm at systemic exposures well above those achieved with recommended topical human use. Because human safety data remain limited, Tapinor should be used during pregnancy only if clearly needed and if the potential benefit to the mother justifies the potential risk to the fetus; a physician should be consulted before use.

Lactation: There are no data on the presence of Tapinor in human milk or its effects on the breastfed infant or on milk production. In animal studies, Tapinor was detected in the offspring of treated lactating animals, suggesting transfer into milk is possible. The developmental and health benefits of breastfeeding should be weighed against the mother's clinical need for Tapinor and any potential risk to the infant; a physician should be consulted, and applying the cream directly to the breast/nipple area should be avoided.

Tapinor is for external (topical) use only and should not be applied to the eyes, lips, mouth, or vaginal mucosa.

• Folliculitis and local skin reactions: Folliculitis is a commonly reported reaction with Tapinor (see Side Effects); contact dermatitis, irritation, or urticaria can also occur. Discontinue and seek medical advice if a reaction is severe, worsening, or associated with signs of a serious allergic reaction (e.g., swelling, difficulty breathing).
• Not for use with strong CYP1A2 substrates without medical advice: Although Tapinor has low systemic absorption and clinically insignificant effects on CYP enzymes at recommended doses, patients on medicines with a narrow therapeutic index that depend heavily on CYP1A2 metabolism should mention Tapinor use to their physician as a precaution.
• Non-steroidal profile: Unlike topical corticosteroids, Tapinor is not associated with skin atrophy (thinning) or hypothalamic-pituitary-adrenal (HPA)-axis suppression, which can make it a suitable option for long-term or sensitive-area use; however, it carries its own distinct risk of folliculitis and local irritation that should be discussed with the physician.
• Avoid unnecessary sun exposure or use of tanning equipment on treated skin areas.
• Keep away from open flame; the cream base may be flammable before it dries.

Topical overdose of Tapinor is unlikely to cause serious systemic toxicity given its minimal systemic absorption, but excessive or prolonged application beyond the recommended area and frequency may increase the risk of local skin irritation, folliculitis, or contact dermatitis. If Tapinor cream is accidentally ingested, or if signs of a severe skin or allergic reaction occur after use, seek immediate medical attention or contact a poison control center/emergency services rather than attempting home treatment.

Store at room temperature (20°C to 25°C; brief excursions between 15°C and 30°C are permitted), away from light, excessive heat, and moisture. Do not freeze. Keep the tube tightly closed and out of reach of children.

Renal and hepatic impairment: Tapinor has not been specifically studied in patients with renal or hepatic impairment; however, because systemic absorption after topical use is minimal, clinically significant accumulation is not expected. Use with the usual precautions and physician guidance.

Elderly (geriatric) patients: Clinical trials of Tapinor included patients aged 65 years and older, and no overall differences in efficacy, safety, or tolerability were observed compared with younger adults; no dose adjustment is required based on age alone.

Pediatric patients: See Pediatric Uses for details specific to children.

The duration of Tapinor treatment should be individualized by the treating physician based on response and tolerability. In clinical trials, Tapinor was studied for continuous use of up to 12 weeks in plaque psoriasis and up to 8 weeks in atopic dermatitis, with longer-term intermittent use also studied. If the skin condition has not improved after 8-12 weeks of regular use, or if it worsens at any time, the patient should follow up with the physician rather than continuing treatment indefinitely on their own.

Aryl hydrocarbon receptor (AhR) agonists; non-steroidal topical anti-inflammatory/dermatologic agents used for plaque psoriasis and atopic dermatitis.

Tapinarof acts by binding to and activating the aryl hydrocarbon receptor (AhR), a receptor and transcription factor present in skin keratinocytes and immune cells. Activation of AhR by Tapinarof is thought to help restore normal skin barrier gene expression, downregulate pro-inflammatory Th17-related cytokines such as interleukin-17 (IL-17), and activate the NRF2 antioxidant response pathway, together reducing the inflammation and skin barrier dysfunction seen in plaque psoriasis and atopic dermatitis. The full mechanism by which this translates into clinical improvement has not been completely elucidated.

Atopic dermatitis: Tapinor is approved for use in children aged 2 years and older with atopic dermatitis, using the same once-daily application as in adults. In clinical trials, the overall safety profile in this age group was generally similar to adults, though upper respiratory tract infections and ear infections were reported somewhat more frequently in younger children. Safety and efficacy of Tapinor for atopic dermatitis in children below 2 years of age have not been established.

Plaque psoriasis: The safety and efficacy of Tapinor for plaque psoriasis have not been established in pediatric patients (below 18 years), and it should not be used for this indication in children outside of a physician's specific direction.
