Pharmacology

đŸ”Ŧ

Mechanism of Action

Lidocaine stabilizes the neuronal membrane by inhibiting the ionic fluxes required for the initiation and conduction of impulses, thereby effecting local anesthetic action. Hydrocortisone is a corticosteroid that exerts anti-inflammatory, antipruritic, and vasoconstrictive actions. It induces phospholipase A2 inhibitory proteins, thereby controlling the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes.
📊

Pharmacokinetics

Absorption:

Bioavailability: Low (topical); Systemic absorption varies with skin integrity, area of application, duration of exposure, and occlusion. For lidocaine, up to 36% can be absorbed from intact skin, higher from mucous membranes or denuded skin. For hydrocortisone, systemic absorption is generally low but can increase with extensive use or damaged skin.
Tmax: Variable (topical); For lidocaine, systemic peak concentrations typically occur within 1-4 hours after topical application.
FoodEffect: Not applicable (topical formulation)

Distribution:

Vd: Not applicable for topical use; for systemic lidocaine, approximately 0.7-2.7 L/kg.
ProteinBinding: Lidocaine: 60-80% (primarily to alpha-1-acid glycoprotein); Hydrocortisone: ~90% (to corticosteroid-binding globulin and albumin).
CnssPenetration: Limited (for topical application; significant systemic absorption could lead to CNS effects for lidocaine).

Elimination:

HalfLife: Lidocaine: Approximately 1.5-2 hours (systemic); Hydrocortisone: Approximately 1.5-2 hours (systemic, but biological half-life is longer).
Clearance: Not applicable for topical use; for systemic lidocaine, approximately 10-20 mL/min/kg.
ExcretionRoute: Renal (primarily as metabolites for both lidocaine and hydrocortisone)
Unchanged: Lidocaine: Less than 10% (systemic); Hydrocortisone: Less than 10% (systemic)
âąī¸

Pharmacodynamics

OnsetOfAction: Lidocaine: Rapid (within 3-5 minutes for local anesthetic effect); Hydrocortisone: Variable (anti-inflammatory effects may take hours to days).
PeakEffect: Lidocaine: Variable, depends on absorption; Hydrocortisone: Variable.
DurationOfAction: Lidocaine: 30-60 minutes (local anesthetic effect); Hydrocortisone: Several hours to days (anti-inflammatory effect).
Confidence: Medium

Drug Interactions

🟡

Moderate Interactions

  • Antiarrhythmics (Class I antiarrhythmics like tocainide, mexiletine): Increased risk of additive cardiac effects if significant systemic lidocaine absorption occurs.
  • Beta-blockers (e.g., propranolol): May reduce lidocaine clearance, increasing systemic levels if significant absorption occurs.
  • CYP3A4 inhibitors (e.g., ketoconazole, ritonavir): May increase systemic levels of hydrocortisone if significant absorption occurs, leading to potential for systemic corticosteroid effects.
  • Other local anesthetics: Increased risk of systemic toxicity if used concurrently with other lidocaine-containing products or other local anesthetics.

Monitoring

đŸ”Ŧ

Baseline Monitoring

Assessment of affected area (e.g., hemorrhoids, anal fissures)

Rationale: To establish baseline severity and identify any contraindications (e.g., infection, open wounds).

Timing: Prior to initiation of therapy.

Patient history (allergies, cardiac conditions, liver disease)

Rationale: To identify potential risks for systemic toxicity or hypersensitivity reactions.

Timing: Prior to initiation of therapy.

📊

Routine Monitoring

Symptom improvement (pain, itching, inflammation)

Frequency: Daily during treatment

Target: Reduction in severity of symptoms

Action Threshold: Lack of improvement after 7 days, or worsening symptoms, warrants re-evaluation by physician.

Local adverse reactions (e.g., irritation, burning, rash, atrophy)

Frequency: Daily during treatment

Target: Absence or mild, transient reactions

Action Threshold: Persistent or severe local reactions, or signs of allergic contact dermatitis, require discontinuation.

Special Patient Groups

🤰

Pregnancy

Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Lidocaine is Pregnancy Category B, but topical corticosteroids are generally Category C. Systemic absorption is low with proper topical use, but extensive use or use on broken skin could increase risk.

Trimester-Specific Risks:

First Trimester: Avoid if possible, or use with caution, due to general concerns with drug exposure during organogenesis.
Second Trimester: Use with caution; monitor for systemic effects if extensive use.
Third Trimester: Use with caution; monitor for systemic effects. Prolonged or extensive use of corticosteroids near term may theoretically affect fetal adrenal development.
🤱

Lactation

Use with caution. Lidocaine is excreted in breast milk in small amounts; hydrocortisone is also excreted in breast milk. The amount absorbed systemically from topical application is generally low, making infant exposure minimal. However, avoid applying to areas where the infant may ingest the cream.

Infant Risk: Low risk with proper, limited topical use. Monitor infant for unusual drowsiness or feeding difficulties (for lidocaine) or signs of adrenal suppression (for hydrocortisone), though unlikely.
đŸ‘ļ

Pediatric Use

Not recommended for routine use in children, especially infants, without specific medical guidance. Children have a larger skin surface area to body weight ratio and less developed skin barrier, increasing the risk of systemic absorption of both lidocaine (leading to CNS/cardiac toxicity) and hydrocortisone (leading to adrenal suppression, growth retardation). Use lowest effective dose for shortest duration if absolutely necessary.

👴

Geriatric Use

No specific dose adjustments are typically needed. However, elderly patients may have thinner skin, which could increase systemic absorption. Monitor for systemic adverse effects, especially if extensive or prolonged use. Use with caution in patients with pre-existing cardiac or hepatic conditions.
