Adverse effects, like therapeutic effects of drugs, are a function of dosage or drug levels at the target organs, so they may be avoided or decreased by means of careful and precise pharmacokinetics, the change of drug levels in the organism in function of time after administration. Adverse effects may also be caused by drug interaction. This ...
Type A: augmented pharmacological effects, which are dose-dependent and predictable [5]; Type A reactions, which constitute approximately 80% of adverse drug reactions, are usually a consequence of the drug's primary pharmacological effect (e.g., bleeding when using the anticoagulant warfarin) or a low therapeutic index of the drug (e.g., nausea from digoxin), and they are therefore predictable.
Adverse effects at targets other than those desired for pharmaceutical treatments often occur with drugs that are nonspecific. If a drug can bind to unexpected proteins, receptors, or enzymes that can alter different pathways other than those desired for treatment, severe downstream effects can develop.
Acute toxicity describes the adverse effects of a substance that result either from a single exposure [1] or from multiple exposures in a short period of time (usually less than 24 hours). [2] To be described as acute toxicity, the adverse effects should occur within 14 days of the administration of the substance. [2]
An adverse side effect of calcium EDTA is renal toxicity. Succimer (DMSA) is the preferred agent in mild to moderate lead poisoning cases. This may be the case in instances where children have a blood lead level >25 μg/dL. The most reported adverse side effect for succimer is gastrointestinal disturbances. [7]
Food poisoning symptoms can vary widely in severity, as can the length of time one feels sick. Many people feel better after several hours, but it is not uncommon for symptoms to persist for 24 to ...
A toxicologist working in a lab (United States, 2008)Toxicology is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms [1] and the practice of diagnosing and treating exposures to toxins and toxicants.
But some research has noted rare but serious side effects of once-weekly, 2.4-milligram (mg) semaglutide injections, such as pancreatitis, acute kidney injury, gallbladder issues, and thyroid cancer.
