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.
Between 1998 and 2007, 33 serious adverse drug or device reactions have been reported by RADAR investigators. The toxicities involved multiple biological system and included thrombotic thrombocytopenic purpura (TTP) (ticlopidine and clopidogrel), thromboembolism (thalidomide and lenalidomide), liver failure (gemtuzumab and nevirapine), hypersensitivity (drug eluting coronary arterial stents ...
Steady state (plateau) levels of the drug are attained after two weeks of administration with a dosage of 150 mg twice daily (300 mg/day total). [82] It is metabolized by CYP2C19, with at least five metabolites. [5] Virtually all of the antiandrogenic activity of nilutamide comes from the parent drug (as opposed to metabolites). [83]
This type of adverse effect that results from pharmaceutical drug exposure is commonly due to interactions of the drug with its intended target. In this case, both the therapeutic and toxic targets are the same. To avoid toxicity during treatment, many times the drug needs to be changed to target a different aspect of the illness or symptoms.
The Naranjo algorithm, Naranjo Scale, or Naranjo Nomogram is a questionnaire designed by Naranjo et al. for determining the likelihood of whether an adverse drug reaction (ADR) is actually due to the drug rather than the result of other factors. Probability is assigned via a score termed definite, probable, possible or doubtful.
The CDC began supplying doses to the SNS in 2007 under a now $427 million contract with the DHHS, according to a Cangene press release. In 2010, the CDC replaced the licensed bivalent botulinum antitoxin AB (BAT-AB) and the investigational monovalent botulinum antitoxin E (BAT-E) with BAT when the former two products indications expired. This ...
Adverse reaction reporting is an important component of New Zealand's pharmacovigilance activities. The Centre for Adverse Reactions Monitoring (CARM) in Dunedin is New Zealand's national monitoring centre for adverse reactions. It collects and evaluates spontaneous reports of adverse reactions to medicines, vaccines, herbal products and ...
Adverse drug reactions – unwanted effects of the drug that the individual experiences (e.g. a sore throat because of a reduced white cell count or an attack of gout because of an increased serum uric acid concentration) Toxicology – the discipline that deals with the adverse effects of chemicals
