Mechanism of action

Acriflavine exerts its antimicrobial effects primarily through intercalation into DNA, which inhibits nucleic acid synthesis. This mechanism disrupts the replication of bacterial cells and may also affect protozoal organisms, thereby contributing to its therapeutic effects.

Pharmacodynamics

Acriflavine displays bactericidal activity against a range of gram-positive and gram-negative bacteria. It is also effective against certain protozoa, making it useful in treating infections caused by these organisms. The drug's efficacy is influenced by concentration and exposure time, with higher concentrations generally leading to increased antimicrobial activity.

Pharmacokinetics

Acriflavine is poorly absorbed when administered orally, leading to minimal systemic exposure. However, when applied topically, it can exert local effects at the site of application. The elimination half-life and detailed metabolic pathways of acriflavine are not well characterized in the available literature, and further studies may be required to elucidate these aspects.

Contra-indications

• Hypersensitivity to acriflavine or any of its components
• Severe renal impairment

Adverse effects

• Local irritation at the application site
• Allergic reactions including rash and pruritus
• Nausea and vomiting

Interactions

Precautions

• Avoid contact with eyes and mucous membranes
• Use with caution in patients with liver impairment

Pregnancy

Acriflavine should be used in pregnancy only if the potential benefit justifies the potential risk to the fetus, as adequate studies in pregnant women are not available.

Breast-feeding
