Nonclinical Toxicology

Route of Administration

Choosing the appropriate route of administration is a critical step in the design of any nonclinical toxicology study. The selection depends on regulatory guidelines, the physicochemical properties of the compound, its intended use, and the most likely route of human exposure. At Vivotecnia, we perform studies using both conventional and non-conventional administration routes, ensuring that exposure accurately reflects clinical or real-world conditions.

Established – 2000

We have the expertise and infrastructure to carry out administration procedures in rodents and non-rodents, always under GLP standards. Our experience guarantees consistency, safety, and reproducibility, while maintaining the highest standards of scientific rigor and animal welfare.

What we offer at Vivotecnia

Systemic Administration Routes

  • Oral
    Standard route for most regulatory studies. Suitable for systemic exposure and subacute to chronic toxicity evaluations.

 

  • Intravenous (bolus and infusion)
    Used for parenteral formulations, bioavailability studies and precise dose control. Catheterization available when required.

 

  • Subcutaneous and intramuscular
    Commonly used for depot formulations, vaccines and biologics, allowing evaluation of both local and systemic exposure.

Respiratory Administration Routes

  • Inhalation
    Fully integrated inhalation platform for aerosols, vapors and gases, supporting acute to chronic studies in rodents and non-rodents.
  • Intranasal and intratracheal
    Precise administration for localized respiratory delivery or absorption studies, frequently used in vaccine and respiratory research.

Topical and Local Administration Routes

  • Topical and dermal
    Applied in cosmetic, chemical and dermatological testing, including occlusive and non-occlusive models.

 

  • Ocular and intrarectal
    Available upon request for specific study designs, using adapted techniques to ensure accurate and reproducible delivery.

Customized and Specialized Administration Methods

  • Special administration methods
    Development of custom techniques such as osmotic pumps, implantable devices or formulation-adapted delivery systems, designed in close collaboration with sponsors.

WHY VIVOTECNIA

Specialized long-term study capabilities

Full regulatory compliance

We guide clients in using 6-month sata within ICH S1B frameworks for possible waiver of the 2-year study when justifiedAll procedures are performed under GLP conditions and in line with EMA, FDA, OECD and ICH guidelines.

Regulatory expertise

Cross-species expertise

Our teams is trained in rodent and non-rodent administration, including large-volume dosing, repeated administration, and dose escalation protocols.

Validates SOPs and consistent delivery

Validates SOPs and consistent delivery

Each administration route follows validated protocols for volume, frequency, needle size and animal restraint, ensuring safety and data integrity.

Committed to animal welfare and sustainability

Animal welfare

Minimally invasive techniques, analgesia protocols and 3Rs implementation are central to all our administration procedures.
