Assessment of Potential Drug–drug Interaction in Stroke Patients

AbstractBackgroundClinically relevant potential drug-drug interactions are considered preventable adverse drug reactions.ObjectiveThe aim of this study was to ascertain the frequency of potential drug-drug interactions in acute ischemic stroke patients and to explore factors associated with occurrence of potentially contraindicated drug-drug interactions.MethodsThis observational retrospective cohort and nested case-control study was carried out among patients treated for acute ischemic stroke at the Neurological Intensive Care Unit in the Clinical Centre Kragujevac, Serbia. The potentially drug-drug interactions for each day of hospitalization were identifi ed using Micromedex® soft ware. Based on the existence or absence of potentially contraindicated drug-drug interactions, the participants were divided into a group of cases (n=111) and the control group (n=444).ResultsA total of 696 patients were analysed. All patients had a minimum of one potential drug-drug interaction during hospitalization. The most common drugs involved in potential drug-drug interactions were aspirin (8.02%), diclofenac (7.49%) and warfarin (7.14%). The number of medications prescribed for simultaneous use during hospitalisation and the use of antipsychotics in therapy signifi cantly increased the likelihood of potentially contraindicated drug-drug interactions aft er adjustment by means of logistic regression for 1.2 and 3 times, respectively.ConclusionsThis study suggests that patients with acute ischemic stroke are frequently exposed to potential drug-drug interactions. It is essential to identify potentially drug-drug interactions in these patients as early as possible in order to prevent adverse drug reactions and ensure safe recovery. Besides, full attention should be paid when adding each new medication in therapy, particularly when a neurologist decides to prescribe antipsychotics, such as risperidone.

Our aim was to determine the prevalence of potential drug-drug interactions (pDDIs) and to identify relevant factors associated with the occurrence of the most dangerous or contraindicated pDDIs (pCDDIs) in hospitalized patients with spontaneous intracerebral hemorrhage (sICH). A retrospective cross-sectional study was performed enrolling all consecutive patients with sICH treated at the Neurological Intensive Care Unit, Clinical Center in Kragujevac, Serbia, during the three-year period (2012)(2013)(2014). The inclusion criteria encompassed patients aged 18 years and over, those diagnosed with ICH, and those prescribed at least two drugs during hospitalization, while we did not include patients whose hospitalization lasted less than 7 days, those who were diagnosed with other neurological diseases and patients with incomplete medical files. For each day of hospitalization, the online checker Micromedex® software was used to identify pDDIs and classify them according to severity. A total of 110 participants were analysed. A high prevalence of pDDIs (98.2%) was observed. The median number of pDDIs regardless of severity, was 8.00 . The pairs of drugs involving cardiovascular medicines were the most commonly identified pDDIs. Twenty percent of the total number of participants was exposed to pCDDIs. The use of multiple drugs from different pharmacological-chemical subgroups and the prescribing of anticoagulant therapy significantly increase the chance of pCDDI (aOR with 95% CI 1. 19 (1.05-1.35) and 7.40 (1.13-48.96), respectively). This study indicates a high prevalence of pDDIs and pCDDIs in patients with sICH. The use of anticoagulant therapy appears to be the only modifiable clinically relevant predictor of pCDDIs.
