Adverse drug reactions (ADR) are much more common in the elderly. Most cases of ADR occur within the framework of commonly prescribed medications at commonly prescribed doses. The VA Center for Medication Safety says, “An adverse drug reaction is harm directly caused by the drug at normal doses, during normal use”. The question then is why does this occur, and why more often to senior adults?
Some doctors think it may be caused by seniors taking medications over long periods of time and often taking more than one prescription drug. A senior may even add in several over-the–counter drugs to that list. We know that as we age, the amount of water that our bodies hold is lower than that of younger people, and the amount of fat on our bodies increase. An older person’s body weight is different in composition than when they were younger. The liver slows down and does not clean out residual drugs like it once was able to. Neither do the kidneys work as well in eliminating drugs from the system. Poor circulation and low blood pressure can also affect the way a senior’s body processes the prescription drug.
While this can be all sound alarming, there are steps being taken to help prevent ADR from happening. The FDA is requiring, at least in part, that some of the testing being done on a drug represent the group that will most likely use it. Computerized systems in drugstores and hospitals are helping to keep track of all the drugs a patient is using. And lastly, increasing awareness by health care professionals is making a difference on how seniors are prescribed drugs and at what doses.
