In contrast, paracetamol is a safe and effective medication that is taken without complications by millions of people. [52] In addition, alternative pain relief medications such as aspirin are more toxic in overdose, whereas non-steroidal anti-inflammatory drugs are associated with more adverse effects following normal use. [53]
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.
[88] [90] Paracetamol is metabolized by the liver and is hepatotoxic; side effects may be more likely in chronic alcoholics or patients with liver damage. [ 87 ] [ 91 ] Until 2010 paracetamol was believed safe in pregnancy however, in a study published in October 2010 it has been linked to infertility in the adult life of the unborn. [ 92 ]
The minimum dosage at which paracetamol causes toxicity usually is 7.5 to 10g in the average person. [2] The lethal dose is usually between 10 g and 15 g. [citation needed] Concurrent alcohol intake lowers these thresholds significantly. Chronic alcoholics may be more susceptible to adverse effects due to reduced glutathione levels. [3]
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 ...
The mechanism of drug action and adverse drug reaction is either physiochemical property based and biochemical based. Adverse drugs reactions can be classified as either idiosyncratic (type B) or intrinsic (type A). Idiosyncratic toxicity is not dosage dependent and defy the mass-action relationship.
Most drugs and procedures have a multitude of reported adverse side effects; the information leaflets provided with virtually all drugs list possible side effects. Beneficial side effects are less common; some examples, in many cases of side-effects that ultimately gained regulatory approval as intended effects, are:
This decreases the possibility of using a higher dose of a single medication if the previous dose is ineffective in treating diseases or relieving symptoms. The significance of using drugs with optimal dose is lowering the occurrence of intolerable side effects, adverse reactions, and possible drug toxicity in patient's body. This increases the ...
