Brief Summary
The study includes two study parts in which blood is collected from the patients. Study part A (observational study, already received positive ethics committee vote; Our sign: 12-330): Use of blood samples gathered during routine blood withdrawal Study part B (interventional study in the sense of additional blood samples but without an investigational product): Optional, for further pharmacokinetic questions: blood withdrawal with a maximum of 20 ml ( ten tubes of 2 ml each) within a maximal study length of four weeks. The primary objective of this study is to gain an overview about drug concentrations in plasma and/or cerebrospinal fluid (CSF), in order to determine pharmacokinetics of drugs in patients. Any drug may be tested, however the initial focus is on antiinfective, antineoplastic, and antipsychotic drugs. Many published studies show that there is a profound lack of information on pharmacokinetics and interactions of many commonly used drugs in clinical routine, and that drug concentrations, if controlled by therapeutic drug monitoring, are not in the therapeutic range (provided that such ranges are known at all).

Outcome Measures
Primary Outcomes (1)
Pharmacokinetic Outcome Measures (e.g., Cmax, AUC)
These assessments rely on multiple measurements over time and the Time Frame may include multiple time points describing the interval at which data are collected
within four weeks after administration of drug of interest
Study Arms (1)
additional blood withdrawals
OTHERTheoretical anyone with taking a drug of interest (see "list of substances and metabolites of interest") can join this trial. But we turn mainly our attention to patient groups who are excluded in modern drug approval studies.
Interventions
Blood withdrawals by either venous puncture or placement of permanent venous catheter.
Eligibility Criteria
You may qualify if:
- Both genders are included.
- Patients willing and capable to confirm written consent prior to enrolment after ample information was given are eligible for the study.
You may not qualify if:
- In Study Part B patients with hemoglobin less 7 mg/dl or less 10 mg/dl including serious symptoms of anemia such as increased heart rate, shortness of breath, dizziness, weakness etc.
- The hemoglobin value must not be 10 days or older.
