| Popis: | Age by itself is not an important risk factor for ADRs. Age-related changes are the consequence of a number of individual factors, for example morbidity associated with polypharmacy, decline in renal or liver function in the elderly, hypoalbuminaemia, reduced body weight, etc. The relationship between gastrointestinal bleeding and non-steroidal anti-inflammatory drugs can be assessed globally in large cohort studies with access to computerized data, but complete accuracy requires access to the original patient records. The increase in the risk of GI bleeding in users of NSAIDs and aspirin was 50% above that in non-users. About a quarter of ADRs in hospitalized patients seem not to arise from purely pharmacological mechanisms. They are mainly due to allergic, anaphylactoid, or idiosyncratic reactions and to intolerance. In such non-pharmacological reactions, the time of exposure, reaction time, and even dosage may be important factors in identification of the causal drug. The use of benzodiazepines can be optimized by taking into account potency, time of action and the different syndromes encountered after withdrawal. Following long-term use problems of relapse and rebound are being increasingly recognized, in addition to organic withdrawal symptoms. In psychiatric patients extrapyramidal disorders due to neuroleptics are common. The rates of these ADRs differ markedly between various drugs, even after dosages and co-medications are taken into account. Epidemiological screening for potentially carcinogenic drugs can only be done in large cohorts of patients with pre-recorded full information sets as may be found in an HMO (Health Maintenance Organization). The findings of several such studies have been published in specialist cancer journals.(ABSTRACT TRUNCATED AT 250 WORDS) |
