The Lidocaine HCl 27%/Phenylephrine HCl 0.05%/Tetracaine HCl 7% Topical Cream is a compounded medication specifically designed to provide localized relief from various conditions. This cream combines the anesthetic effects of both lidocaine and tetracaine, which are amide and ester-type local anesthetics, respectively. Lidocaine works by blocking sodium channels and, consequently, the transmission of nerve impulses, which helps to numb the treated area. Tetracaine, being more potent than lidocaine, enhances the anesthetic effect, allowing for deeper and more prolonged numbness. The addition of phenylephrine HCl, a vasoconstrictor, helps to reduce swelling and bleeding by constricting blood vessels in the applied area. This can be particularly beneficial in procedures where minimizing bleeding is desired.

The cream is formulated as a semisolid preparation and is dispensed in a pump mechanism container. This delivery system allows for a convenient, hygienic, and controlled application, ensuring that the correct dose is administered each time. The pump mechanism also helps to prevent contamination of the product, maintaining its integrity throughout its use. The topical application of this cream is indicated for the temporary relief of pain and discomfort associated with conditions such as minor skin irritations, insect bites, minor cuts, and burns. It may also be used as a local anesthetic for minor surgical procedures where surface anesthesia is appropriate, such as laser hair removal or superficial dermatological procedures.

For patients, it is important to apply the cream as directed by a healthcare provider. The area of application should be clean and dry, and patients should be advised to avoid contact with eyes and mucous membranes. The duration of effect and onset of action can vary depending on the site of application and individual patient factors. For prescribers, it is crucial to consider the patient's medical history, including any known allergies to local anesthetics or sympathomimetic amines, before prescribing this formulation. Additionally, the maximum dosage and duration of application should be tailored to the patient's needs to minimize the risk of systemic toxicity.

The topical cream formulation containing Lidocaine HCl 27%, Phenylephrine HCl 0.05%, and Tetracaine HCl 7% is a potent combination used for localized treatment, providing both anesthetic and vasoconstrictive effects. Lidocaine and tetracaine are local anesthetics that work by blocking sodium channels, thereby reducing the sensation of pain. Phenylephrine is a vasoconstrictor that can reduce swelling and prolong the duration of the anesthetic effect by decreasing blood flow to the area of application.

When considering drug interactions, it is important to note that although the systemic absorption of these agents is generally low when applied topically, there is still potential for interaction with other medications. Lidocaine is metabolized by the liver's cytochrome P450 3A4 (CYP3A4) enzymes. Therefore, drugs that inhibit or induce CYP3A4 may affect the metabolism of lidocaine. Strong CYP3A4 inhibitors, such as some azole antifungals (ketoconazole, itraconazole), macrolide antibiotics (erythromycin, clarithromycin), and protease inhibitors (ritonavir), could potentially increase lidocaine levels, leading to systemic toxicity. Conversely, CYP3A4 inducers, such as rifampin and phenytoin, could potentially decrease lidocaine levels and reduce its efficacy.

Phenylephrine's vasoconstrictive action could be potentiated by other sympathomimetic drugs, leading to increased blood pressure and potential cardiovascular effects. Caution is advised when using this formulation in patients taking monoamine oxidase inhibitors (MAOIs), as these can prolong and intensify the effects of phenylephrine. Additionally, patients on antihypertensive medications or those with pre-existing hypertension should be monitored closely, as phenylephrine can counteract the effects of some antihypertensive drugs.

Tetracaine, like lidocaine, is a local anesthetic and has the potential for systemic toxicity, particularly in cases of overuse or accidental ingestion. It is important to consider the total dose of local anesthetics when using combination products to avoid additive systemic effects. Patients on antiarrhythmic drugs, which can have additive cardiac effects with local anesthetics, should be monitored for cardiac function.

Given the high concentration of local anesthetics in this formulation, there is a risk of methemoglobinemia, a condition where hemoglobin is modified such that it cannot release oxygen effectively to body tissues. Drugs that induce methemoglobinemia, such as sulfonamides, acetaminophen, and nitrates, should be used with caution in patients receiving this topical cream.

It is also important to consider the potential for allergic reactions or cross-sensitivity among patients who are allergic to amide-type local anesthetics. In such cases, alternative treatments should be considered.

Patients should be advised to apply the cream only to intact skin and avoid application to large areas or broken skin, which could increase systemic absorption. Additionally, the use of occlusive dressings over the application site should be avoided unless directed by a healthcare provider, as this may also increase systemic absorption of the active ingredients.

This formulation is designed for the treatment of localized conditions where anesthetic and vasoconstrictive actions are beneficial, such as minor surgical procedures, laser therapy, or as part of a pain management strategy. It is not intended for widespread use or for treatment of systemic conditions.

For any questions or concerns regarding the use of this formulation or potential drug interactions, please reach out to us at Bayview Pharmacy. We are here to provide guidance and support to ensure the safe and effective use of this medication.

The Lidocaine HCl 27%/Phenylephrine HCl 0.05%/Tetracaine HCl 7% Topical Cream is a compounded medication that combines the properties of three active pharmaceutical ingredients (APIs) to provide localized relief from various conditions. This semisolid preparation is dispensed in a pump mechanism, which allows for convenient and controlled application on the skin. The pump ensures that each dose is consistent, reducing the risk of over- or under-dosing and facilitating ease of use for patients.

Lidocaine and tetracaine are both local anesthetics that work by blocking sodium channels in the neuronal cell membrane. This action inhibits the initiation and conduction of nerve impulses, thereby providing a numbing effect to the applied area. Lidocaine, with a concentration of 27%, acts quickly to provide rapid onset of anesthesia, while tetracaine, at 7%, has a longer duration of action, which prolongs the anesthetic effect. The combination of these two anesthetics allows for both immediate and sustained relief from pain and discomfort.

Phenylephrine HCl, present at 0.05%, is a vasoconstrictor. It works by stimulating alpha-adrenergic receptors in the vascular smooth muscle, leading to vasoconstriction. This action reduces blood flow to the area of application, which can help to decrease swelling and bleeding. This is particularly useful in procedures where minimizing bleeding is important, such as during minor surgical interventions or the treatment of hemorrhoids.

The formulation is designed to treat localized conditions that require both an anesthetic and vasoconstrictive effect. It can be used for procedures such as skin biopsies, laser therapy, or as pre-procedural anesthesia to minimize discomfort. Additionally, it may be used in the management of minor skin irritations, anorectal disorders, or other conditions where a combination of anesthetic and vasoconstrictive actions is beneficial.

It is important for both patients and prescribers to understand that this topical cream should be used as directed by a healthcare professional, and it is intended for external use only. The specific dosing and duration of treatment will depend on the condition being treated and the patient's response to therapy. As with any medication, there may be potential side effects, and it is essential to monitor the patient for any adverse reactions.
