Calcium Dobesilate + Lidocaine + Dexamethasone

Introduction

Calcium Dobesilate + Lidocaine + Dexamethasone is a combination medication used topically to treat conditions involving inflammation, pain, and impaired circulation. Each component provides a specific therapeutic effect: Calcium Dobesilate acts as a venotonic and anti-inflammatory, Lidocaine is a local anesthetic, and Dexamethasone is a potent corticosteroid that reduces inflammation.

Uses

This combination is used for:

Treating localized inflammation and pain, often associated with conditions like hemorrhoids, varicose veins, and other venous disorders.
Managing symptoms of superficial inflammatory conditions, including pain and swelling.
Providing symptomatic relief in conditions requiring anti-inflammatory and analgesic effects.

Mechanism of Action

Each component works through different mechanisms:

Calcium Dobesilate: Enhances capillary resistance and reduces inflammation by stabilizing cell membranes and decreasing the permeability of capillaries.
Lidocaine: Provides local anesthesia by blocking sodium channels in the nerve cells, preventing the propagation of nerve impulses and thus alleviating pain.
Dexamethasone: A corticosteroid that reduces inflammation by inhibiting the release of inflammatory mediators and suppressing the immune response.

How Long Does It Take to Work?

Calcium Dobesilate typically takes a few days to show noticeable effects on capillary function and inflammation. Lidocaine provides rapid pain relief, usually within minutes of application. Dexamethasone begins to reduce inflammation within hours, with full effects observed over several days of consistent use.

Absorption

When applied topically, the absorption of Calcium Dobesilate, Lidocaine, and Dexamethasone is minimal. Lidocaine is absorbed through the skin and mucous membranes and can have systemic effects if used excessively. Dexamethasone is absorbed in small amounts and its systemic effects are generally limited. Calcium Dobesilate's systemic absorption is negligible.

Route of Elimination

For the components used topically:

Calcium Dobesilate: Minimal systemic absorption; primarily metabolized locally.
Lidocaine: Metabolized primarily in the liver and excreted via the kidneys.
Dexamethasone: Metabolized in the liver and excreted in the urine.

Dosage

2-3 times daily. Apply in the morning and bedtime and if possible after defecation. If the ointment is preferred, use the applicator by screwing it to the tube. Insert the applicator as deep as possible in the anus then press the tube gently while withdrawing it. In this case, the tube is sufficient for 8 applications. In case of external hemorrhoids or anal pruritus, apply a thin layer of the ointment several times a day. The duration of the treatment is generally of some days. The doctor must be informed if, after 1 to 2 weeks of treatment, the symptomatology has not improved or has worsened.

Calcium Dobesilate, Lidocaine HCI & Dexamethasone Acetate Ointment should be applied 2-3 times daily preferably in the morning and at bedtime, if possible apply after defecation. In the case of internal hemorrhoids apply the ointment by the applicator. In cases of external hemorrhoids and anal pruritus, apply a thin layer of the ointment several times a day. The duration of the treatment is generally of some days. The physician must be informed if, after 1 to 2 weeks of treatment the symptomatology has not improved or has worsened.

Method of use of this ointment:
For internal use-

Before use remove the cap from the tube.
Pierce the tube membrane by inverting the cap.
Attach the applicator (supplied) to the tube.
Squeeze the tube to fill the applicator and lubricate the tip with ointment for smooth insertion.
Insert the applicator gently and to full extend into the anus and squeeze once again from the end of the tube to force the required amount of ointment into the anal canal.
Remove the applicator after application and discard it.
Try not to have defecation for a couple of hours after an internal application.

For external use-

Squeeze the tube of ointment and apply a small amount to the finger.
Apply the ointment around the outside of the anus with a finger.
Wash the hands thoroughly with warm water and soap after each application.
Reattach the cap to tube.

The dosage depends on the specific formulation and the condition being treated. Typical recommendations include:

Apply a thin layer of the cream or ointment to the affected area 1-3 times daily.
Do not apply more frequently than directed to avoid potential side effects.

Administration

Apply the medication topically to the affected area. Clean and dry the area before application. Use a clean applicator or your fingers to apply a thin layer of the cream or ointment. Avoid applying to large areas of broken skin or open wounds unless directed by a healthcare provider.

Side Effects

Common side effects may include:

Skin irritation or rash at the site of application
Itching or burning sensation
Dryness or redness of the skin

Serious side effects could include:

Allergic reactions such as hives, swelling, or difficulty breathing
Signs of systemic absorption, such as increased blood pressure or mood changes

Toxicity

Topical application generally minimizes the risk of systemic toxicity. However, excessive use or application to large areas of broken skin may lead to systemic effects, especially with Lidocaine and Dexamethasone. Symptoms of toxicity might include severe skin reactions or systemic effects like dizziness or palpitations.

Precautions

Precautions include:

Avoid use on large areas of broken or irritated skin.
Monitor for potential allergic reactions or skin irritation.
Use with caution in patients with cardiovascular disorders, diabetes, or other systemic conditions that could be exacerbated by systemic absorption.

Interaction

Drug interactions are minimal with topical application, but caution should be exercised when used with other topical products that might cause additional irritation or have systemic effects.

Disease Interaction

Special consideration is needed for individuals with:

Pre-existing skin conditions, such as eczema or psoriasis, where topical medications may exacerbate the condition.
Cardiovascular or renal disorders due to potential systemic absorption effects.

Drug Interaction

Potential drug interactions include:

Other topical agents that could cause additive effects or increase the risk of skin irritation.
Systemic medications that may interact with Lidocaine or Dexamethasone if absorbed in significant amounts.

Food Interactions

Food interactions are not typically significant for topical use. However, it is advisable to avoid consuming large amounts of grapefruit juice, which can affect the metabolism of medications metabolized by the liver.

Pregnancy Use

During pregnancy, this combination should be used only if clearly needed. Calcium Dobesilate is generally considered safe, while Lidocaine and Dexamethasone should be used with caution. Consult a healthcare provider to weigh the benefits and risks.

Lactation Use

The use of this combination during lactation should be done with caution. Minimal amounts of Lidocaine and Dexamethasone may be excreted in breast milk. It is advisable to use the medication sparingly and consult a healthcare provider for guidance.

Acute Overdose

Acute overdose from topical application is rare. Symptoms of overdose may include severe skin reactions, systemic effects such as dizziness, or palpitations. In case of suspected overdose, seek immediate medical attention. Treatment may involve supportive care and monitoring.

Contraindication

This combination is contraindicated in individuals with:

Known hypersensitivity to Calcium Dobesilate, Lidocaine, or Dexamethasone
Severe systemic infections or conditions where topical corticosteroids are contraindicated

Use Direction

Apply a thin layer of the cream or ointment to the affected area as directed. Avoid excessive use and do not apply to large areas of broken skin. Discontinue use if severe irritation or allergic reaction occurs and consult a healthcare provider if symptoms persist.

Storage Conditions

Store the product at room temperature, between 15°C and 30°C (59°F and 86°F). Keep it in a dry place away from direct sunlight and moisture. Keep out of reach of children.

Volume of Distribution

The volume of distribution for topical medications like Calcium Dobesilate, Lidocaine, and Dexamethasone is generally localized to the application site with minimal systemic distribution. Specific values are not well-documented for topical formulations.
