Why medications cause more adverse effects is seniors

The main reason for this is, as we grow older our major organs such liver and kidney function less efficiently. The liver is the major organ for metabolism and kidney is major organ for excretion of drugs from our body. While, other organs being the lungs and skin, and colon through feces. The physicians need to be careful in prescribing the medications, and it would be better if the peak level in the blood and the organs metabolizing and excreting the medications are not the same if possible. At least the timing of medication should be such that two drugs have the same possible side-effect and the same organ of metabolism be prescribed at different timings of the day. Most physicians are not very proficient in deciding these factors. The ObamaCare EHR has the drug-drug interaction and drug-allergy space, which is very helpful. The Stage 2 EHR would also include Data Analytics and Clinical Support so these physicians would be prevented from defaulting the system.
