Formula Information

A small arrow pointing down

This unique compounding formulation combines Lidocaine, Misoprostol, Naltrexone HCl, and Phenytoin Sodium in a topical ointment base, designed to provide localized relief and therapeutic benefits directly to the affected skin area. Each milliliter of the ointment contains 40 mg of Lidocaine, a local anesthetic that helps to numb the skin, reducing pain and discomfort. This can be particularly beneficial for patients experiencing skin inflammation or wounds that are painful to the touch.

Misoprostol, present at 10 mcg per milliliter, is a prostaglandin analogue that has protective effects on the skin, promoting healing and helping to prevent ulcer formation. This can be especially useful in wound healing, as it may aid in the prevention of secondary infections and promote a conducive environment for tissue repair.

Naltrexone HCl, included at a concentration of 10 mcg per milliliter, is typically known for its systemic use in addiction treatment. However, in this topical formulation, it is used for its anti-inflammatory properties, which can help reduce local inflammation and may be beneficial in treating inflammatory skin conditions.

Phenytoin Sodium, at 20 mcg per milliliter, is an anticonvulsant that has been found to have wound healing properties when applied topically. It can promote tissue regeneration and is often used in the management of various skin conditions where skin repair is needed.

The ointment is compounded in a semi-solid base that provides an occlusive layer, protecting the skin and enhancing the absorption of the active ingredients. The greasy or oily nature of the base ensures that the medication stays in contact with the skin for an extended period, allowing for sustained release of the medication to the affected area. This can be particularly advantageous for conditions that require continuous delivery of medication for relief and healing.

Patients and prescribers considering the use of this compounded formulation should be aware of the potential interactions and contraindications associated with each active ingredient. It is important to use this medication under the guidance of a healthcare professional who can monitor its effectiveness and safety. For any questions or additional information regarding this formulation, please reach out to us at Bayview Pharmacy. Our team of knowledgeable compounding pharmacists is here to support and provide guidance tailored to each patient's unique needs.

Drug Interactions

A small arrow pointing down

The topical ointment formulation containing Lidocaine, Misoprostol, Naltrexone HCl, and Phenytoin Sodium is designed for localized treatment of various skin conditions. Lidocaine is a local anesthetic that provides temporary relief of pain by blocking nerve signals in the skin. Misoprostol is a prostaglandin analogue that can promote healing and is used off-label for its potential to increase blood flow and promote tissue repair. Naltrexone is an opioid antagonist that, in very low doses, may reduce inflammation and promote healing. Phenytoin is an anticonvulsant that has been used in wound healing due to its potential to stimulate fibroblast proliferation.

When using this multi-ingredient topical ointment, it is important to consider potential drug interactions. Lidocaine should be used with caution in patients taking antiarrhythmic drugs like amiodarone or sotalol due to the increased risk of cardiac effects. Concurrent use of other local anesthetics should be avoided to prevent additive systemic toxicity. Misoprostol may interact with antacids containing magnesium, as they can worsen diarrhea, a potential side effect of misoprostol. Naltrexone, even at low doses, can interfere with the effects of opioid medications; patients using opioid analgesics should avoid this ointment as it may precipitate withdrawal symptoms or reduce the analgesic effect of their medication. Phenytoin's interaction profile is extensive; it can affect the metabolism of certain drugs leading to either increased toxicity or decreased efficacy. For example, it may increase the metabolism of corticosteroids and decrease their effectiveness.

Patients should be advised to inform their healthcare provider of all medications they are taking, including over-the-counter drugs and herbal supplements, to avoid potential interactions. Prescribers should review the patient's medication profile for interactions before prescribing this ointment. It is also important to monitor for any signs of adverse reactions or unusual symptoms when using this formulation, especially if the patient has a history of drug sensitivities or is taking multiple medications for other conditions.

For any questions or concerns regarding the use of this topical ointment or its potential drug interactions, please reach out to us at Bayview Pharmacy. Our team of compounding pharmacists is available to provide the necessary guidance to ensure safe and effective use of this medication.

How Does it Work

A small arrow pointing down

The topical ointment you have been prescribed is a unique compound that combines four active ingredients, each with a specific role in treating various skin conditions. This semi-solid formulation is designed to be applied externally to the skin, where it provides a greasy or oily base that facilitates the delivery of the medication directly to the affected area. The ointment is dispensed in a tube for ease of application.

Lidocaine is a local anesthetic that works by blocking nerve signals in your body. When applied to the skin, lidocaine can reduce pain and discomfort by numbing the area. This can be particularly beneficial for painful inflammatory conditions or when pain relief is needed at the site of a wound.

Misoprostol is a medication that has protective effects on the skin and mucous membranes. It can help promote healing and provide relief from certain types of skin ulcers. Misoprostol's role in this compound is to aid in the healing process by encouraging tissue repair and reducing inflammation.

Naltrexone HCl is traditionally known for its use in treating addiction, but at very low doses, it has been found to have anti-inflammatory properties. In this formulation, naltrexone is included at a microdose level to help modulate the immune response and reduce inflammation, which can be beneficial in various dermatological conditions.

Phenytoin Sodium is an anticonvulsant that also has effects on promoting wound healing. When applied topically, phenytoin can help to stimulate the growth of new tissue and enhance the repair of damaged skin. This makes it a valuable component of the ointment for treating wounds or skin damage.

Together, these ingredients work synergistically to provide pain relief, reduce inflammation, protect the skin, and promote healing. This makes the ointment particularly suitable for treating conditions such as skin inflammation, infections, or aiding in the healing of wounds. It is important to apply the ointment as directed by your healthcare provider to ensure the best possible outcome. If you have any questions about how this formulation works or its suitability for your condition, please reach out to us at Bayview Pharmacy. We are here to support your treatment and provide the necessary information to ensure safe and effective use of your medication.

Other Uses

A small arrow pointing down

While the primary indication of this Lidocaine/Misoprostol/Naltrexone HCl/Phenytoin Sodium topical ointment is typically for the treatment of conditions such as skin inflammation, infections, or promoting wound healing, there are additional uses where this compound may prove beneficial. The presence of lidocaine, a local anesthetic, allows for this ointment to potentially be used for temporary relief of pain associated with minor burns, insect bites, or other localized painful skin conditions. The analgesic properties of lidocaine make the formulation suitable for applications where the reduction of local discomfort is desirable.

Misoprostol, a synthetic prostaglandin E1 analog, can provide anti-inflammatory properties and has been shown to aid in the healing of pressure sores and skin ulcers, potentially extending the use of this ointment to such conditions. Misoprostol's role in promoting mucosal protection and healing could also make the formulation worth exploring for off-label use in patients with other types of skin breakdown or ulcerative conditions, under the close supervision of a healthcare provider.

Naltrexone is classically known for its ability to block opioid receptors, but at microdoses, it might have anti-inflammatory effects that could contribute to the management of certain inflammatory skin disorders. It is worth noting, however, that naltrexone's inclusion in this formulation could necessitate caution for patients currently using opioid analgesics, as it may reduce their effectiveness.

The inclusion of phenytoin, an anticonvulsant, has been studied for its wound-healing properties, particularly in diabetic foot ulcers, by promoting fibroblast proliferation and collagen deposition. Therefore, this multi-ingredient topical ointment may be considered for use in complex skin ulcers where enhanced tissue regeneration is needed.

It is important to underscore that the varied therapeutic effects of this formulation's components allow it to have potential applications beyond its primary use, although any such off-label uses should be pursued only under professional medical advice. As is the case with any medication, patients with skin sensitivity or allergies to any component of the formulation should exercise caution. This ointment should be used as directed by a healthcare professional, and any adverse reactions should be reported immediately. As compounding pharmacists, we are available to address any specific questions or concerns about the potential uses of this product. For further inquiries and to discuss individual cases, please do not hesitate to contact us at Bayview Pharmacy.
