[Polymedication among elderly patients Preventing drug related problems and inappropriate medication].

Polypharmacy is a common phenomenon among elderly patients. A simultaneous intake of a large number of drugs can possibly lead to drug-related problems due to an increased risk of drug interactions, medication errors, contra-indications, but also a lack of patient compliance. Elderly patients are particularlyvulnerable because of physiological and pathological aging. Therefore we need to be particularly attentive to their medication, especially in case of polypharmacy. A systematic review of the medication for elderly patients should regularly be performed to prevent the occurrence of potentially drug-related problems. In view of his central role in the dispensing of medicines, the pharmacist can carry out this medication review in consultation with the treating physician.
