Toxicity Testing in Animals

Toxicity Testing in Animals

Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...

Drug Toxicity: Dose-Dependent Reactions

Drug Toxicity: Dose-Dependent Reactions

Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...

Oral Hypoglycemic Agents: α-Glucosidase Inhibitors

Oral Hypoglycemic Agents: α-Glucosidase Inhibitors

α-glucosidase inhibitors, including acarbose (Precose), miglitol (Glyset), and voglibose (Voglib) (primarily available in Asia), are drugs that control blood sugar levels by delaying the digestion of starch and disaccharides. They achieve this by inhibiting α-glucosidase enzymes in the intestine, which slow the absorption of carbohydrates in the intestine, which in turn leads to a prolonged release of the glucoregulatory hormone GLP-1 from intestinal L-cells.
Acarbose and miglitol are typically...

Drug toxicity: Drug–Drug Interaction

Drug toxicity: Drug–Drug Interaction

Drug–drug interactions can precipitate toxicity through multiple mechanisms. Absorption interactions alter how drugs enter the body, exemplified when ranitidine increases the absorption of basic drugs, while cholestyramine decreases the levels of propranolol. Protein binding interactions occur when drugs share the same binding sites on plasma proteins. Drugs like aspirin and warfarin, when bound in excess, can lead to increased free drug concentrations, enhancing the potential for...

Drug Toxicity: Overview

Drug Toxicity: Overview

Drug toxicity quantifies the harm a compound causes to an organism, varying by dose and potentially impacting whole systems or specific organs like the liver. Toxic reactions may arise from venomous insect or spider bites, with effects ranging from mild symptoms to severe outcomes such as brain damage or death. Common forms of acute poisoning include ethanol intoxication and overdose of pain or fever medications, with substances like GHB and heroin being particularly lethal at doses close to...

Diabetic Ketoacidosis l: Introduction

Diabetic Ketoacidosis l: Introduction

DefinitionDiabetic ketoacidosis (DKA) is an acute, life-threatening complication of diabetes mellitus, characterized by a triad of hyperglycemia (blood glucose >250 mg/dL), ketonemia or ketonuria, and metabolic acidosis (arterial pH <7.30 and serum bicarbonate <18 mEq/L). It results from insulin deficiency combined with elevated levels of counterregulatory hormones—glucagon, catecholamines, cortisol, and growth hormone—leading to increased lipolysis, hepatic ketone production, and...

Summary

Xylitol is toxic to dogs, causing hypoglycemia and liver failure. Early treatment is crucial for a better prognosis, but severe cases remain risky.

Area of Science:

Veterinary Toxicology
Small Animal Medicine
Toxicology

Background:

Xylitol, a popular sugar substitute in human products, is increasingly common.
While safe for humans, xylitol poses significant health risks to dogs.

Purpose of the Study:

To summarize the toxic effects of xylitol ingestion in dogs.
To outline the clinical signs, treatment, and prognosis associated with xylitol toxicosis.

Main Methods:

Review of existing literature on xylitol toxicosis in canines.
Analysis of dose-dependent effects and clinical outcomes.

Main Results:

Ingestion of >0.1 g/kg xylitol can cause hypoglycemia in dogs.
Doses >0.5 g/kg are associated with acute liver failure (hepatotoxicosis).

Treatment involves dextrose for hypoglycemia and intensive care for liver damage.

Conclusions:

Xylitol ingestion is a serious veterinary emergency.
Prognosis is good for uncomplicated hypoglycemia but guarded to poor for severe hepatotoxicosis.
