Preclinical Toxicology CRO Services

We understand the importance of in vivo safety pharmacology assessments for evaluating the safety of drug products.

Our preclinical toxicology research services form a crucial foundation for drug development processes. We evaluate a range of biological systems and uncover valuable insights into the toxicodynamics and toxicity profiles of new compounds.

Our team employs cutting-edge techniques and methodologies to reveal potential risks and guide decision-making in pharmaceutical research. Check out the toxicology services that we offer at AniLocus:

Toxicity Testing Services

  • Acute Toxicity Testing

    • Single-Dose Toxicity Study: Administer a high dose of the test substance to mice and observe for signs of acute toxicity over a short duration, typically 24-72 hours.

    Subacute Toxicity Testing:

    Subchronic Toxicity Testing:

    Chronic Toxicity Testing:

    • Chronic Toxicity and Carcinogenicity Study: Administer the substance over an extended period (usually 1-2 years) to assess chronic toxicity and carcinogenic potential.

    Reproductive Toxicity Testing:

    Developmental Toxicity Testing:

    Genotoxicity Testing:

    • Ames Test: Use bacterial strains to assess the substance’s mutagenic potential.
    • Micronucleus Test: Assess the substance’s ability to induce micronuclei in the mouse’s bone marrow cells.
    • Comet Assay: Examine DNA damage in mouse tissues following exposure to the substance.

    Dermal Toxicity Testing:

    • Dermal Irritation Study: Apply the substance to the skin to assess its irritant potential.
    • Dermal Sensitization Study: Evaluate the potential for the substance to induce skin sensitization.

    Inhalation Toxicity Testing:

Toxicokinetics ADME Studies

Pharmacokinetics (PK) Studies:

  • Bioavailability Assessment: We can determine the extent and rate at which a substance is absorbed into the bloodstream following different routes of administration (e.g., oral, intravenous).
  • Plasma Concentration Profiling: We can measure the concentration of the test substance in blood plasma over time to understand its pharmacokinetic profile.

Absorption Studies:

  • Permeability Assessments: We measure the permeability of the substance across biological membranes (e.g., intestinal, blood-brain barrier) using in vivo models.
  • GI Tract Absorption: We study the absorption of oral medications in the gastrointestinal (GI) tract to understand factors affecting bioavailability.

Tissue Distribution Studies:

  • Tissue Sampling: We collect and analyze samples from various tissues to assess the distribution of the substance throughout the body.
  • Metabolite Identification: We identify and characterize metabolites in different tissues to understand where the substance is metabolized.

Metabolism Studies:

  • In Vivo Metabolism: Evaluate in vivo metabolism by administering the substance to animal models and analyzing metabolites in biological samples.

Excretion Studies:

  • Renal Excretion: We evaluate the excretion of the substance and its metabolites through the urine to assess the renal clearance.
  • Biliary Excretion: We assess the excretion of the substance into bile and its subsequent elimination through the feces.

Stability Studies:

  • Stability Assessment: We determine the stability of the substance in various biological matrices (e.g., plasma, tissue homogenates) under different storage conditions.
  • Formulation Stability: We evaluate the stability of drug formulations to ensure shelf-life and administration reliability.

Mass Balance Studies:

  • Total Recovery Studies: We conduct mass balance studies to account for the total recovery of the administered substance and its metabolites in various excreta (urine, feces).

Pharmacokinetic Modeling and Simulation:

  • PK/PD Modeling: We perform pharmacokinetic/pharmacodynamic modeling to understand the relationship between drug exposure and effects, aiding in dose optimization.

Analytical Services

  • Analytical Method Development: We create robust analytical methods for quantifying the substance and its metabolites in biological samples.
  • Bioanalysis: We can perform quantitative bioanalysis using validated analytical methods.

Consultation and Regulatory Liaison:

  • Scientific Expertise: We offer expert guidance and consultation on ADME study design, execution, and interpretation.
  • Regulatory Interactions: We assist clients in interactions with regulatory agencies, addressing inquiries and ensuring compliance.
