Grapefruit juice is an inhibitor of the cytochrome P450 (CYP) 3A4 enzyme system, one of the enzyme systems responsible for the metabolism of colchicine. This study will evaluate the effec...
CP-945,598 is eliminated primarily by enzyme CYP3A. Grapefruit juice may affect the activity of CYP3A and alter the amount of CP-945,598 in the blood. This study will therefore compare the...
In this prospective pharmacokinetic we investigate the following topics: - The influence of grapefruit juice and orange juice on the steady-state pharmacokinetics of sunitinib in ...
Similar to the well publicized "grapefruit juice effect", ongoing studies are evaluating the interaction potential of other dietary substances on drug disposition. This study is designed t...
The purpose of this study is to find out about the safety and effectiveness of the study drug, sirolimus, in patients with uveitis and to utilize the potential effectiveness of sirolimus, ...
Perivascular epithelioid cell tumor (PEComa) is a family of mesenchymal tumors. Conventional chemotherapy has little activity in this disease, but case reports are available on the activity of mammali...
Cirrhosis is often associated with portal hypertension and portal-systemic collateral vessels formation attributed to angiogenesis, which leads to severe complications as hepatic encephalopathy. Sirol...
Therapeutic drug monitoring (TDM) of sirolimus is essential in transplant recipients. We evaluated the performance of a new electrochemiluminescence immunoassay (ECLIA) for measuring sirolimus concent...
Recent epidemiological studies have suggested that phenolic compounds present in grapefruit play an important role in the bioactive properties of this fruit. However, the consumption of fresh grapefru...
Grapefruit and lime cutins were analyzed and compared in order to obtain information about their cutin architecture. This was performed using a sequential hydrolysis, first with trifluoroacetic acid t...
A plant species of the genus CITRUS, family RUTACEAE that provides the familiar grapefruit. There is evidence that grapefruit juice inhibits CYTOCHROME P-450 isoform 3A4, resulting in delayed metabolism and higher blood levels of a variety of drugs.
A macrolide compound obtained from Streptomyces hygroscopicus that acts by selectively blocking the transcriptional activation of cytokines thereby inhibiting cytokine production. It is bioactive only when bound to IMMUNOPHILINS. Sirolimus is a potent immunosuppressant and possesses both antifungal and antineoplastic properties.
A serine threonine kinase that controls a wide range of growth-related cellular processes. The protein is referred to as the target of RAPAMYCIN due to the discovery that TACROLIMUS (commonly known as rapamycin) forms an inhibitory complex with TACROLIMUS BINDING PROTEIN 1A that blocks the action of its enzymatic activity.
Retrograde flow of gastric juice (GASTRIC ACID) and/or duodenal contents (BILE ACIDS; PANCREATIC JUICE) into the distal ESOPHAGUS, commonly due to incompetence of the LOWER ESOPHAGEAL SPHINCTER.
A plant genus of the family RUTACEAE. They bear the familiar citrus fruits including oranges, grapefruit, lemons, and limes. There are many hybrids which makes the nomenclature confusing.
