5 PHARMACOLOGICAL PROPERTIES

5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Anti-acne, ATC code: D10A F52

Erythromycin is known to be efficacious, at 4%, in the topical treatment of acne vulgaris. Zinc, topically, is established as an aid to wound healing. The zinc acetate is solubilised by complexing with the erythromycin, and delivery of the complex is enhanced by the chosen vehicle.

5.2 Pharmacokinetic properties

Absorption

The complex does not survive in the skin, and erythromycin and zinc penetrate independently. The erythromycin penetrates, and is partially systemically absorbed (0 - 10% in vitro, 40 - 50% in animal studies); that portion absorbed is excreted in 24 - 72 hours. The zinc is not absorbed systemically.

5.3 Preclinical safety data

Non-clinical data from repeated dose toxicity and reproduction and developmental toxicity studies reveal no additional hazard other than those described elsewhere in the SPC.
