Zindaclin

Zindaclin is a prescription-only gel containing the active ingredient clindamycin, a lincosamide antibiotic. It is used for the topical treatment of mild to moderate inflammatory acne vulgaris.

Clindamycin works against Cutibacterium acnes, the bacteria that cause acne, and reduces the inflammatory response in the skin. Ideally, it should be used in combination with benzoyl peroxide or a retinoid to prevent the development of resistance.

Zindaclin is applied once daily and is approved for adults and adolescents aged 12 years and older.

Clindamycin has an antibacterial effect:

Mechanism of action:

• Inhibits bacterial protein synthesis (50S subunit of the ribosomes)
• Bacteriostatic against Cutibacterium acnes
• Reduces the concentration of free fatty acids on the skin
• Anti-inflammatory side effect

Additional effects:

• Reduces neutrophil chemotaxis
• Inhibits complement activation
• Acts indirectly against comedones by reducing inflammation

Time course:

• First improvement: 2-4 weeks
• Optimal effect: 6-8 weeks

Zindaclin is suitable for:

• Mild to moderate inflammatory acne
• Papulopustular acne
• Adults and adolescents aged 12 years and older

Important:

• Best used in combination with benzoyl peroxide (to counter resistance)
• Or in combination with a retinoid

Not suitable for:

• Severe acne (systemic therapy required)
• Non-inflammatory acne (comedones only)
• Monotherapy over a longer period (risk of resistance)
