Robenidinum (Robenidine) API Manufacturers & Suppliers

Robenidine (CAS Number 25875-51-8) is an antimicrobial agent classified primarily as a coccidiostat used in veterinary medicine. Its primary application is in the control and prevention of coccidiosis, a protozoal infection caused by coccidian parasites, which presents a significant health risk and economic burden in poultry production. Robenidine acts by inhibiting the growth and reproductive cycles of these parasites, thereby slowing disease progression and reducing parasitic load in affected animals.

Chemically, robenidine is a chlorobenzene derivative belonging to the class of amidines and guanidines. Although detailed pharmacodynamics and the precise molecular mechanism of action remain to be fully elucidated, its antiparasitic efficacy is linked to interference with metabolic or replicative processes specific to coccidia.

Pharmacokinetic data for robenidine are limited; however, its absorption, distribution, metabolism, and excretion (ADME) parameters are consistent with compounds administered in feed to achieve localized antiparasitic activity in the gastrointestinal tract. Oral administration in poultry is the common route, optimizing exposure at the site of coccidian infection while minimizing systemic circulation.

Safety considerations include its use exclusively in veterinary contexts with appropriate withdrawal periods to prevent residual drug presence in edible tissues. Toxicological profiles indicate that while generally well tolerated in target species at recommended doses, improper use or overdose may pose risks. Monitoring is required to mitigate development of resistance. To address this, robenidine is often used intermittently or rotated with other antimicrobials to delay emergence of resistant strains and sustain therapeutic efficacy.

Robenidine is approved for veterinary use in various regions, although specific registration status varies. It plays a strategic role in integrated coccidiosis control programs within poultry farming.

From an API sourcing perspective, it is important to ensure pharmaceutical-grade quality consistent with veterinary medicinal standards. Suppliers should demonstrate compliance with relevant regulations and provide certificates of analysis confirming identity, purity, and absence of contaminants. Given its widespread veterinary use, robust supply chain reliability and adherence to Good Manufacturing Practice (GMP) are critical for consistent product performance and regulatory compliance.
