On each gram of it, the drug includes erythromicine thiocyanate in the amount equivalent to the 200 mg erythromicine activity. It includes Erythrosine E 127 as a coloring substance. It is in the form of fine homogenous powder having pink color.

Erythromicine is an antibiotic having toxicity whose macrolide group produced during the development of microorganisms called "Streptomyces erythreus" is low. Its antibacterial effect occurs in order to block the formation of peptide bond on bacteria at the end of the peptide chain that gets bigger by connecting to the ribosomal sub units of 50 S, and therefore in order to prevent the protein synthesis. Erythromicine is basically a bacteriostatic. It has bactericide effect at high concentration levels.
Gram – positive aerobes (Bacillus sp, Corynebacterium sp., Erysipelotrix rhusiopathiae, Staphylococcus sp., Streptococcus sp. (including those which secrete beta – lactamase resistant to penicilline), Gram – negative aerobes (Actinobacillus sp., Campylobacter sp., Leptospira sp), Anaerobic bacteria (Actinomyces sp., Bacteroides sp. (except for B.fragilis), Clostridium sp, some of Fusobacterium sp., anaerobic coccuses) are sensitive to eythromicine.
Enterococcus sp., some of Bordetella sp., Haemophilus sp., Legionella sp., Erlichia sp., Pasteurella sp.. show sensitivity at intermediate level.
Resistant Bacterias: They are Nocardia sp., Pseudomonas sp., Chlamydia psittaci, Mycobacterium sp., Enterobacteriaceae, B. fragilis, E.coli, Klebsiella sp.
Erythromicine absorbed from digestive tract reaches to the highest blood concentration level within 1 – 2 hours, and its concentration level decreases rapidly within 4 – 6 hours following its application. Most part of it is extracted by saffron and some part of it is extracted by urine.

It is indicated in the treatment of infections caused by the bacterias sensitive on hens, and especially in the treatments of Chronic Respiratory Tracts Diseases (PPLO), Coryza, synovitis and sinusitis.

Unless otherwise is recommended by the veterinary surgeon, it is applied at 20 – 25 mg / kg live weight / day dose.
It is practically used on hens by mixing up20–25 gram Erivet® to the daily fresh water of the hens per 200 kg live weight. It is recommended not to give water to the animals 2 – 3 hours before the application of the lotion. The treatment lasts 3 – 5 days. Lotion must be prepared every day as fresh.

It is offered for sale in plastic bottles of 100 gr and 1000 gr.
