Ketoconazole 2%/Terbinafine HCl 1% Topical Cream is a specially compounded medication designed to treat fungal skin infections. This cream combines the antifungal properties of two active ingredients, ketoconazole and terbinafine hydrochloride, to provide a broad-spectrum approach to managing dermatophytic infections and yeast infections of the skin. Ketoconazole is an imidazole antifungal agent that works by disrupting the fungal cell membrane, leading to the death of the fungus. Terbinafine HCl, on the other hand, is an allylamine antifungal that inhibits the enzyme squalene epoxidase, which is a key component in the fungal cell wall synthesis pathway. By inhibiting this enzyme, terbinafine HCl causes the fungal cell to become deficient in ergosterol, an essential component of fungal cell membranes, leading to fungal cell death.

The cream is formulated as a semisolid preparation, which allows for a smooth and uniform application to the affected area. The inclusion of a pump mechanism in the packaging is designed to provide patients with a convenient and controlled method of application, ensuring that the correct dose is administered each time. This is particularly beneficial for maintaining consistent treatment and improving patient adherence to the medication regimen. The cream is intended for topical use only and should be applied to clean, dry skin as directed by a healthcare provider.

This compounded formulation is particularly useful for treating localized fungal infections such as tinea pedis (athlete's foot), tinea cruris (jock itch), tinea corporis (ringworm), and cutaneous candidiasis. The dual-action of ketoconazole and terbinafine HCl makes this cream an effective option for infections that may be resistant to single-agent therapy. It is important for patients to follow the prescribed treatment duration, even if symptoms improve before the medication is finished, to prevent recurrence of the infection.

Patients should be advised of potential side effects, which may include local irritation, redness, or itching at the application site. Serious side effects are rare when the cream is used as directed. Prescribers should consider the patient's medical history, including any known allergies to the active ingredients or excipients in the formulation, before recommending this treatment. Additionally, prescribers should monitor for signs of improvement and any adverse reactions throughout the course of treatment.

The combination of ketoconazole and terbinafine hydrochloride in a topical cream formulation is designed to treat fungal skin infections by leveraging the antifungal properties of both active ingredients. Ketoconazole is an imidazole derivative that works by inhibiting the synthesis of ergosterol, a key component of fungal cell membranes, leading to increased membrane permeability and ultimately cell death. Terbinafine hydrochloride, a member of the allylamine class, primarily acts by inhibiting squalene epoxidase, another enzyme important for ergosterol synthesis. This dual-action approach enhances the antifungal efficacy against a broad spectrum of dermatophytes and yeasts.

When considering drug interactions for this topical cream, it is important to note that systemic absorption of both ketoconazole and terbinafine is minimal with proper topical application. However, certain factors such as the use of occlusive dressings, application to large surface areas, or use in patients with a compromised skin barrier could potentially increase systemic absorption. In such cases, the potential for drug interactions similar to those seen with oral administration may arise.

Ketoconazole, when absorbed systemically, is known to inhibit cytochrome P450 3A4 (CYP3A4) enzymes and can increase plasma concentrations of drugs metabolized by this pathway. This could potentially lead to increased risk of adverse effects or toxicity when used concomitantly with drugs such as certain statins, calcium channel blockers, and benzodiazepines. Additionally, ketoconazole may interact with drugs that prolong the QT interval, increasing the risk of cardiac arrhythmias.

Terbinafine, when absorbed systemically, can also affect the metabolism of other drugs. It may decrease the effectiveness of drugs metabolized by CYP2D6, such as certain antidepressants and beta-blockers. Conversely, drugs that induce or inhibit CYP2D6 may alter the metabolism of terbinafine, affecting its efficacy and safety profile.

It is also important to consider the potential for additive irritant or sensitization effects when using this combination cream with other topical agents. Patients should be advised to inform their healthcare provider of all topical products they are using to avoid potential interactions.

Patients should be instructed to apply the cream as directed and to avoid the use of occlusive dressings unless advised by a healthcare provider. They should also be aware of signs of systemic side effects, such as nausea, dizziness, or skin rash, and report these to their healthcare provider immediately. Prescribers should evaluate the patient's current medication list for potential interactions, especially if there is a concern for increased systemic absorption of the topical agents.

The Ketoconazole 2%/Terbinafine HCl 1% Topical Cream is a specially compounded medication that combines the antifungal properties of two active ingredients, ketoconazole and terbinafine hydrochloride, in a cream base. This formulation is designed to treat fungal skin infections by providing a dual mechanism of action against the fungi responsible for conditions such as athlete's foot, jock itch, ringworm, and other dermatophyte infections.

Ketoconazole is an imidazole antifungal agent that works by disrupting the fungal cell membrane. It inhibits the synthesis of ergosterol, a key component of the fungal cell membrane, leading to increased membrane permeability and ultimately cell death. Ketoconazole is effective against a broad spectrum of fungi, including dermatophytes and yeasts.

Terbinafine hydrochloride, on the other hand, is an allylamine antifungal that primarily acts by inhibiting squalene epoxidase, an enzyme involved in the biosynthesis of ergosterol in fungi. This leads to a deficiency in ergosterol and causes an accumulation of squalene within the cell, which is toxic to the fungal cell. Terbinafine HCl is particularly effective against dermatophytes and has fungicidal activity, meaning it can kill the fungal cells.

The combination of these two antifungal agents in a single cream enhances the spectrum of antifungal activity and may improve the overall efficacy of the treatment. The cream is formulated to be applied topically, directly to the affected area. The semisolid preparation is dispensed in a pump mechanism, which allows for convenient, controlled, and hygienic application. This delivery system helps to ensure that a consistent dose is applied each time, which is important for the effectiveness of the treatment.

When applied to the skin, the cream creates a local environment that is inhospitable to the growth and survival of the fungi. With regular application as directed by a healthcare provider, the cream can reduce the fungal load, alleviate symptoms, and promote healing of the infected skin. It is important to use the medication for the full prescribed duration, even if symptoms improve before the end of the treatment period, to prevent recurrence of the infection.

Patients and prescribers should be aware that while this compounded formulation is designed to maximize therapeutic outcomes, it is essential to follow the specific instructions for use and to monitor for any potential side effects. If there are any questions or concerns regarding the use of Ketoconazole 2%/Terbinafine HCl 1% Topical Cream, or if additional guidance is needed, please reach out to us at Bayview Pharmacy. Our team of compounding pharmacists is here to support and provide the necessary information to ensure safe and effective treatment.

Ketoconazole and terbinafine hydrochloride are established antifungal agents commonly employed in the treatment of various dermatophytic infections such as athlete's foot, ringworm, and jock itch. The combination of these two active ingredients in a 2% ketoconazole and 1% terbinafine HCl topical cream may offer a broader spectrum of antifungal activity, given the complementary mechanisms of action of these agents. While these are the primary indications, there may be other potential uses for this topical formulation.

Aside from the aforementioned dermatophyte infections, this cream could potentially be used off-label for the treatment of other fungal skin conditions that have not responded to monotherapy with either ketoconazole or terbinafine alone. For example, certain cases of cutaneous candidiasis and seborrheic dermatitis might benefit from the combined potency of the two antifungals. Moreover, certain yeast infections of the skin, especially those caused by Malassezia species which may be associated with conditions such as pityriasis versicolor, can be targets for this compounded formulation.

It is important to highlight that off-label uses should only be considered when a healthcare provider has determined that the benefits of such treatment outweigh the risks, and when other approved therapeutic options have been exhausted or are not feasible. It is also essential to observe caution in the use of this combination cream, as it may not be suitable for individuals with known hypersensitivity to either active ingredient or for use in areas with open wounds or mucous membranes. The pump mechanism is designed to provide controlled dosage, but patients should always follow the prescribed amount and duration of treatment to minimize the risk of side effects.

Lastly, while not extensively studied, there may be additional investigational uses of this cream based on emerging antifungal research, but such applications would require further scientific validation before recommending this formulation for those purposes.
