• Residue Studies

Vetspin conducts residue studies to determine drug residue levels in tissues, milk, and eggs. These studies are essential for establishing withdrawal times and ensuring regulatory compliance for veterinary medicinal products — a key requirement for product registration and consumer safety.

Residue studies are performed at Vetspin across all food-producing species, including cattle and other ruminants, pigs, poultry, and rabbits.

Our bioanalytical assessment begins with method development and GLP validation, followed by the analysis of tissue samples collected during the study. This process guarantees accurate, reliable, and traceable data in full accordance with international regulatory standards.

• Tolerance Studies

Vetspin performs safety and tolerance studies in both target and non-target species, including overdose and margin-of-safety assessments.
Data from target animal safety studies are a regulatory requirement for the registration of veterinary medicinal products in countries adhering to VICH guidelines.

At Vetspin, tolerance studies are conducted on all food-producing animals, including ruminants (such as cattle and sheep), swine, poultry (chickens, turkeys, and guinea fowl), and rabbits.
All studies are carried out by qualified veterinary surgeons and trained technicians, under the supervision of an experienced Study Director, ensuring compliance with GLP and animal welfare standards.

• PK / BEQ (Bioequivalence) Studies

Pharmacokinetic / Bioequivalence (PK–BEQ) Studies

Vetspin conducts pharmacokinetic (PK), bioequivalence (BEQ), and bioavailability studies to evaluate drug absorption, distribution, metabolism, and elimination in target species.
These studies provide essential data for dossier submission and regulatory approval of veterinary medicinal products.

Vetspin performs PK studies in food-producing animals, including cattle, swine, poultry, and rabbits.
All studies are conducted by qualified veterinary surgeons and trained technicians, under the supervision of an experienced Study Director, and in full compliance with GLP procedures.

We carry out single- and multiple-dose PK, bioavailability, and bioequivalence studies, with data analyzed using non-compartmental pharmacokinetic methods.
All analyses are performed by trained data analysts under the supervision of an experienced pharmacokineticist, ensuring scientific accuracy and regulatory consistency.

• Clinical Studies

Vetspin conducts clinical and efficacy studies in accordance with Good Clinical Practice (GCP) guidelines to evaluate the safety and performance of veterinary medicinal products under practical field conditions.
