Interindividual variability in drug response is a major clinical problem. Polymedication and genetic polymorphisms modulating drug-metabolising enzyme activities (cytochromes P450, CYP) are identified sources of variability in drug responses. We present here the relevant data on the clinical impact of the major CYP polymorphisms (CYP2D6, CYP2C19 and CYP2C9)(More)
Polypharmacy in the elderly complicates therapy, increases cost, and is a challenge for healthcare agencies. In the context of the evolving role of the pharmacist, this systematic review examines the effectiveness of interventions led by pharmacists in reducing polypharmacy. A computerised search was conducted using Medline, Embase geriatrics and(More)
Non-steroidal anti-inflammatory drugs (NSAIDs) are the most frequently used drugs, either on prescription or over-thecounter (OTC). Their daily dosage is based on randomised controlled trials and an empirical clinical assessment of their efficacy and toxicity that allows dose adjustment. The individual response can however be altered by environmental and(More)
The use of analgesics is based on the empiric administration of a given drug with clinical monitoring for efficacy and toxicity. However, individual responses to drugs are influenced by a combination of pharmacokinetic and pharmacodynamic factors that can sometimes be regulated by genetic factors. Whereas polymorphic drug-metabolizing enzymes and drug(More)
Vitamin K antagonists (VKAs) are prescribed worldwide and remain the oral anticoagulant of choice. These drugs are characterized by a narrow therapeutic index and a large inter- and intra-individual variability. P-glycoprotein could contribute to this variability. The aim of this study was to investigate the involvement of P-gp in the transport of(More)
BACKGROUND AND OBJECTIVE Oral fixed drug combination analgesics have potential advantages over monotherapy, but these can only be attained through careful design. RESULTS The main reasons for developing combination analgesics are to gain efficacy and to reduce toxicity. Analgesic combinations interact pharmacokinetically, or pharmacodynamically, or both,(More)
Adverse drug reactions (ADRs) represent an important risk for patients and have a significant economic impact on health systems. ADRs are the fifth most common cause of hospital death, with a burden estimated at 197,000 deaths per year in the EU. This has a societal cost of <euro>79 billion per year. Because of this strong impact in public health,(More)
BACKGROUND Bisphosphonate drugs can be used to prevent and treat osteoporosis and to reduce symptoms and complications of metastatic bone disease; however, they are associated with a rare but serious adverse event: osteonecrosis of the maxillary and mandibular bones. This condition is called bisphosphonate-related osteonecrosis of the jaw or BRONJ. BRONJ is(More)
The objective of this study was to identify the most clinically relevant drug–drug interactions (DDIs) at risk of affecting acenocoumarol safety in our tertiary care university hospital, a 2,000 bed institution. We identified DDIs occurring with acenocoumarol by combining two different sources of information: a 1-year retrospective analysis of acenocoumarol(More)
Skin atrophy is an adverse effect of topical corticosteroids (TCs) which, as an established non-life-threatening effect, has been poorly reported by trials involving these drugs. Atopic dermatitis and psoriasis are example of disorders that require repeated therapies with TCs; however, assessing the atrophogenic activity of TCs is still an issue. This study(More)
