- Brief Summary
This study is to demonstrate the safety, tolerability, pharmakokinetic and pharmacodynamic effect of a single oral dose of BAY63-2521 in patients with pulmonary hypertension due to chronic obstructive pulmonary disease (COPD).
- Detailed Description
In addition to the pharmacodynamic and pharmacokinetic variables, the following laboratory variables were assessed:
* Hematology: Leucocytes, erythrocytes, hemoglobin, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), platelets, white blood cell (WBC), partial thromboplastin time (PTT), prothrombin time (Quick), international normalized ratio (INR) (prothrombin time expressed in relation to normal value) ;
* Clinical chemistry: aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (AP), gamma glutamyl transpeptidase (GGT), creatine phosphokinase (CK), lipase, cholinesterase (CHE), glucose, creatinine, urea, uric acid, bilirubin, total protein, serum albumin, sodium, potassium, calcium, chloride.
And due to the small number of subjects analyzed at several local labs, no summary statistics were provided.
