Drugs are supposed to make us better, but sometimes they actually harm us.
The word 'pharmaceutical' derives from the Greek 'pharmakon', which means 'medicine' or perhaps 'toxin'. These might seem including complete opposites, but in fact medicines and toxins are extremely similar - they both affect our body chemistry. And quite a few medicines have been developed via toxins, such as the center drug digoxin.
Any compound that interferes with our internal biochemistry can possess powerful effects. All medicines possess side-effects, but they are applied because their benefits outweigh their harmful effects. The safety involving medicines is assessed by comprehensive testing and clinical trials. But clinical trials cannot get rid of the risks and, unfortunately, some people will be made ill, perhaps even mortally wounded, by their medication.
Adverse drug reactions (ADRs) are surprisingly frequent. A study carried out involving nearly 20 000 admissions to help hospital in Merseyside in 2004 identified that 1225 (6. 5%) were on account of adverse drug reactions. They accounted for 4% of hospital bed capacity and the annual cost to the NHS of ADRs was estimated for being £466 million.
This suggests of which, at any one time, the same as up to seven 800-bed hospitals may be occupied by patients admitted with ADRs.
The figures also claim that ADRs leading to hospital admission cause around 5700 deaths annually - so all fatal ADRs, including those occurring while patients have been in hospital, may exceed 10 000 annually.
It is not experimental new drugs which are the main problem. The biggest reason for hospital admissions is aspirin, which can cause bleeding in the instinct. Reactions to diuretics and the actual blood thinner warfarin were additionally common.
ADRs are thus a major health problem - in fact, one of the leading causes of death in the united states. This is why there is this kind of the intensive research effort to name the genetic factors linked to adverse reactions, and so prevent patients from receiving drugs that could seriously harm them.
