The drugs have many kinds of influence on an organism of the sick person.
However the most significant and widespread is the pharmacotherapy - influence by medicinal substances or we usually say drugs.
In such distribution of drugs, there are both positive and negative sides.
Presently in connection with opening of set of individual pharmaceutical factories, the enterprises, drugs stores rash purchase of drugs, their irrational reception, self-treatment by very widespread fact.
Taking drugs without medical prescription entails the extremely negative consequences and even lethal outcomes.
The pharmacotherapy is based on use of combinations of
drugs. It is dictated by symptomatic action of the majority of known
drugs. Representation about symptomatic action of
drugs was included into a medical practice, what even the modern pharmacology calls the whole groups of
drugs on them anti-symptom to diseases effect: anti-cough
drugs, analgesic
drugs, anti-inflammatory
drugs, hypotensive
drugs, etc. Meanwhile neither the inflammation, nor cough, neither a pain, nor increase of arterial pressure in itself are not illness; they only demonstrate its separate displays, symptoms. As each illness has a lot of symptoms, and the doctor has no means for causal pharmacotherapy, he is forced to create a composition from several
drugs to capture a maximum quantity of symptoms of illness. Exception in this respect, apparently, should make antimicrobial preparations (sulfanilamides, antibiotics) which are really etiotropic action
drugs. But as a pure mono infection drugs, all less often here again it is necessary to resort to a combination of
drugs. And the complicating phenomena (for example, from heart at pneumonias) demand additional purpose of
drugs.
