CKET

CKET is a topical anti-dandruff/antifungal combination shampoo indicated for:

• Established/first-line use: Treatment and control of dandruff (pityriasis capitis).
• Established/guideline-supported use: Treatment of seborrheic dermatitis of the scalp.
• Adjunct/supportive use: Management of mild scalp fungal (Malassezia-associated) conditions as an adjunct to, not a replacement for, physician-directed antifungal therapy when infection is more than superficial.

CKET is not indicated for systemic fungal infections, and it is not a substitute for oral antifungal therapy when that is clinically required.

Each application of Ketoconazole, Zinc Pyrithione, Aloevera, and Glycerin shampoo contains:

• Ketoconazole - an imidazole antifungal agent.
• Zinc Pyrithione - an antifungal/antibacterial and cytostatic agent.
• Aloevera (Aloe vera extract) - a soothing and moisturizing agent.
• Glycerin - a humectant/moisturizing agent.

CKET is a combination medicated shampoo formulated for topical use on the scalp. It combines two antifungal agents (ketoconazole and zinc pyrithione) that target the yeast Malassezia species implicated in dandruff and seborrheic dermatitis, together with aloe vera and glycerin, which are added to soothe the scalp and reduce the dryness/irritation that can accompany dandruff and its treatment.

CKET is intended for external scalp use only and is available as an over-the-counter/prescription medicated shampoo depending on local labeling.

CKET belongs to the therapeutic class of topical antifungal and anti-dandruff scalp preparations (medicated shampoos).

Ketoconazole, Zinc Pyrithione, Aloevera, and Glycerin combines agents with complementary mechanisms:

• Ketoconazole is an imidazole antifungal that inhibits fungal cytochrome P450-dependent 14-alpha-demethylase, blocking conversion of lanosterol to ergosterol, an essential component of the fungal cell membrane. This disrupts membrane synthesis and integrity, producing activity against Malassezia (Pityrosporum) species associated with dandruff and seborrheic dermatitis.
• Zinc Pyrithione has antifungal and antibacterial activity and is cytostatic, slowing the abnormally rapid turnover of scalp skin cells that contributes to flaking; it also reduces Malassezia colonization.
• Aloevera provides a soothing, anti-irritant, moisturizing effect on the scalp skin.
• Glycerin acts as a humectant, drawing and retaining moisture in the skin to counter dryness.

With topical scalp application as directed, systemic absorption of the active antifungal components is minimal.

CKET is for external topical (scalp) use only:

• Wet hair and scalp thoroughly.
• Apply an adequate amount of CKET and massage gently into the scalp to work up a lather.
• Leave in place for 3-5 minutes (or as directed) to allow contact time.
• Rinse thoroughly with water.
• Avoid contact with eyes; if contact occurs, rinse with plenty of water.
• Do not swallow. Not for use on broken, inflamed, or infected skin beyond the labeled scalp use.

Because CKET is applied topically to the scalp with minimal systemic absorption, clinically significant drug-drug interactions are unlikely when used as directed. However:

• Concurrent use of other irritant or medicated topical scalp products (e.g., other keratolytics, topical corticosteroids, other antifungal shampoos) may increase local irritation; space out use or consult a physician before combining products.
• Avoid combining with other harsh chemical hair treatments (e.g., permanent wave solutions, hair dyes, relaxers) around the same time, as this may increase scalp irritation or affect treatment efficacy.

Inform your physician or pharmacist about all other topical or systemic medicines and products you are using.

Most side effects of CKET are local and mild, related to skin/scalp contact:

• Scalp itching, burning, or stinging
• Dryness or irritation of the scalp
• Redness of the scalp or skin
• Changes in hair texture, or increased hair loss/oiliness/dryness of hair (uncommon)
• Contact dermatitis or allergic skin reaction (uncommon)

Seek medical attention if severe irritation, rash, swelling, or signs of an allergic reaction occur; discontinue use and consult a physician if excessive irritation develops.

CKET is applied topically to the scalp, and systemic absorption of its active ingredients is minimal when used as directed, so it is generally considered low risk in pregnancy and lactation. However, as with any medicine, CKET should be used during pregnancy and breastfeeding only if clearly needed, and only as directed; consult a physician before use if pregnant, planning pregnancy, or breastfeeding.

Observe the following precautions when using CKET:

• For external scalp use only; avoid contact with the eyes and other mucous membranes.
• Discontinue use and consult a physician if excessive scalp irritation, burning, or an allergic reaction occurs.
• Do not use on broken, inflamed, or actively infected skin beyond the labeled scalp application, unless directed by a physician.
• Use exactly as directed and for the recommended duration; do not stop, extend, or use more/less frequently than directed without medical advice, and do not share this product with others without medical advice.
• If symptoms of dandruff or seborrheic dermatitis do not improve within 2-4 weeks of regular use, or if they worsen, consult a physician.
• Keep out of reach of children.

CKET is intended for topical scalp use, and overdose in the systemic sense is unlikely with correct use. If accidental ingestion or significant accidental exposure (e.g., large-area misuse) occurs, or if severe irritation or an allergic reaction develops, seek immediate medical attention or contact a poison control center/emergency services rather than attempting home treatment.

Store at room temperature (below 30°C), away from light and moisture. Keep out of reach of children.

Use in Special Populations

Pediatric use: Safety and efficacy of CKET in young children have not been well established; use in children should be under medical supervision, and it should generally be avoided in infants unless specifically directed by a physician.

Elderly: No specific dose adjustment is generally required for topical use in elderly patients; use as directed.

Renal/hepatic impairment: Because systemic absorption from topical scalp use is minimal, no specific dosage adjustment is established for renal or hepatic impairment; use as directed.

Pregnancy and lactation: See Pregnancy and Lactation section.

Typical duration for CKET is twice-weekly use for 2-4 weeks to control dandruff or seborrheic dermatitis, followed by less frequent maintenance application (e.g., every 1-2 weeks) as needed and as directed by a physician or the product label. Do not extend or shorten the recommended course without medical advice.

Topical antifungal / anti-dandruff combination (medicated shampoo containing an imidazole antifungal, an antifungal/antibacterial cytostatic agent, and skin-conditioning agents).

Ketoconazole, Zinc Pyrithione, Aloevera, and Glycerin works through complementary mechanisms: ketoconazole inhibits fungal ergosterol synthesis (via 14-alpha-demethylase inhibition), disrupting the fungal cell membrane of Malassezia species; zinc pyrithione exerts direct antifungal/antibacterial and cytostatic effects that slow excessive skin cell turnover on the scalp; aloe vera soothes and moisturizes irritated scalp skin; and glycerin acts as a humectant to reduce dryness. Together these actions reduce the fungal burden and flaking associated with dandruff and seborrheic dermatitis while conditioning the scalp.

Safety and efficacy of CKET have not been well established in young children and infants. Use in pediatric patients should be under the guidance of a physician, who will weigh the potential benefit against any risk before recommending use.
