The (positive) effects of antihypertensive drugs in the cardiovascular risk management are undoubted. However, like all drugs, antihypertensive drugs also have negative side-effects. Especially the elderly, are more susceptible for these adverse effects. It's not clear whether the benefits outweight the risks. So is it possible to deprescribe antihypertensive drugs and minimise risks for adverse events, while maintining blood-pressure levels in accordance with guidelines?  

• A prospective observational PK/PD to study the target attainment for β-lactam antibiotics in critical ill patients and its associated risk factors.
• A multi-centre, randomised controlled trial to assess the efficacy and cost-effectiveness of model-based TDM of beta-lactam and fluoroquinolone antibiotics.

1. Optimasation of the flucloxacillin absorptiontest.
2. PK modeeling of cefotaxim in critically ill patients.
3. PK modeling of flucloxacillin in mice.

Part 1: Optimizing ribavirin therapy in transplant recipients with a chronic hepatitis E virus infection by devoloping a NONMEM model for ribavirin. Part 2: Improving immunosuppressive therapy in liver transplant recipients by performing 2 RCT's in which different immunosuppresive strategies will be compared to modify the tacrolimus related toxicity in this population. Part 3: Evaluate the contribution of an outpatient medication service for liver transplant recipients.

Outpatient Parenteral Antimicrobial Therapy (OPAT) service provides antimicrobial therapy by parenteral infusion without hospitalization. Vancomycin is a widely used antibiotic in OPAT, however a drawback of its application in OPAT is the need for traditional blood sampling at a blood sampling facility for therapeutic drug monitoring. By developing a dried blood spot sampling method (i.e. a finger prick), enabling patients to collect their own sample at home, the costs of OPAT may be further reduced and patient satisfaction may be increased.
