From ChatGPT:
Ethacridine (also known as ethacridine lactate) is an antiseptic compound that belongs to the acridine dye group. It has a bright yellow color and is chemically related to acriflavine. Its full chemical name is 2-ethoxy-6,9-diaminoacridine lactate monohydrate.
Chemical and Pharmacological Profile

• Chemical Formula: C₁₈H₂₁N₃O₄
• Form: Usually available as the lactate salt (ethacridine lactate) in aqueous solution.
• Properties:
  • Yellow crystalline powder
  • Soluble in water and alcohol
  • Exhibits antimicrobial and antiseptic properties

Uses of Ethacridine

1. Antiseptic for Wound Care

• Traditionally used as a topical antiseptic for:
  • Cleansing wounds
  • Treating ulcers
  • Preventing infection in burns and cuts
• Its activity is mainly bacteriostatic (prevents bacterial growth) against Gram-positive bacteria such as Staphylococcus aureus, and to a lesser extent, Gram-negative bacteria.

2. Obstetric Use (Medical Abortion)

• In some countries (especially in Asia and Eastern Europe), ethacridine lactate is used for inducing abortion in the second trimester.
  • The procedure is known as Ethacridine Instillation Abortion (EIA).
  • A diluted solution (commonly 0.1–0.2%) is injected intra-amniotically to induce uterine contractions and fetal expulsion.
  • It is considered safer and less systemically toxic compared to hypertonic saline methods.

3. Veterinary and Laboratory Use

• Occasionally employed as an antiseptic in veterinary medicine.
• Used in biological research for its fluorescent properties and DNA intercalation ability.

⚠️ Safety and Side Effects

• Topical use: Generally well-tolerated; may cause mild irritation or skin staining (yellow discoloration).
• Intra-amniotic use: Requires medical supervision—potential complications include infection, uterine rupture, or incomplete abortion.
• Systemic absorption is minimal, but not used orally or intravenously due to toxicity risks.
