A retrospective analysis of haematological side effects of olaparib in excess-weight and normal BMI patients with ovarian cancer.

Background: Olaparib is the first poly(ADP-ribose) polymerase inhibitor approved in Europe for the treatment of platinum-sensitive patients with newly diagnosed or recurrent platinum-sensitive ovarian cancer with a confirmed BRCA mutation or homologous recombination deficiency (HRD). Epidemiological studies have shown an incompatible association between ovarian cancer and obesity, but there have also been scientific reports indicating that obesity, especially severe obesity, increases the risk of ovarian cancer. Olaparib has a wide range of side effects, especially anaemia and neutropenia, which may lead to dose reduction or therapy discontinuation.

The oxidation and hypoglycaemic effect of sorafenib in streptozotocin-induced diabetic rats.

Background: Diabetes reduces the activity of CYP3A4 and may increase the exposure for the drugs metabolized by the isoenzyme. Sorafenib is a multi-targeted tyrosine kinase inhibitor (TKI), used for the treatment of advanced renal cell carcinoma, hepatocellular carcinoma and radioactive iodine resistant thyroid carcinoma. The TKI undergoes CYP3A4-dependent oxidative transformation, which may be influenced by hyperglycaemia.

The influence of a single and chronic administration of venlafaxine on tramadol pharmacokinetics in a rabbit model.

Background: The combined use of tramadol with selective serotonin and norepinephrine reuptake inhibitors e.g. venlafaxine may be associated with serotonin syndrome.

Effects of Low-Dose Escherichia coli Lipopolysaccharide-Induced Endotoxemia on Morphine Pharmacokinetics in an Animal Model.

Objective: Systemic inflammation may change the bioavailability and pharmacokinetics of opioids. However, there are insufficient data on morphine pharmacokinetics in mild inflammatory conditions. This study aimed to determine the pharmacokinetics of morphine during low-dose endotoxemia in rabbits.

In vitro - in vivo evaluation of a new oral dosage form of tramadol hydrochloride--controlled-release capsules filled with coated pellets.

The aim of this study was an in vitro - in vivo evaluation of a new oral dosage form of tramadol hydrochloride (TH), controlled-release capsules filled with coated pellets, 100 mg (TC), compared to the sustained release tablets, Tramal Retard, 100 mg (TR). In vitro release study of both formulations showed a similar release profile of TH over 8 h (f2 was 52). In vivo study (single oral, 100 mg dose administration in 8 rabbits) showed that the amount of TH absorbed into the systemic circulation after TC and TR administration was also similar (90% CI for AUC(0-t) and AUC(0-infinity) were 90-124% and 97-109%, respectively).

Stability of calcium folinate (Teva) in concentrate after re-use and in dilute infusions in 0.9% NaCl in polyethylene bags.

The study concerned the stability of calcium folinate in concentrate in glass vials and diluted in polyethylene (PE) bags stored at 15-25 degrees C and 2-8 degrees C for up to 34 days. Original vials of calcium folinate injection (10 mg/mL, Teva) were stored at room and refrigerator temperatures and subjected to re-piercing at 1, 2, 3, 7, 14, 22, 28, 30 and 34 days following the initial piercing. Calcium folinate infusions at nominal concentrations of 0.

Sunitinib in combination with clarithromycin or azithromycin - is there a risk of interaction or not?

Background: Macrolides are the most widely prescribed antibiotics. Clarithromycin is a well-known inhibitor of cytochrome P450 CYP3A4 and causes numerous drug interactions that are not found for azithromycin. CYP3A4 is involved in the metabolism of the new oral multikinase inhibitor sunitinib and its active N-desethyl metabolite (SU012662).

The physical and chemical stability of cisplatin (Teva) in concentrate and diluted in sodium chloride 0.9%.

Aim Of The Study: The subject of study was the stability of cisplatin in concentrate in glass vials and diluted in polyethylene (PE) bags stored at 15-25°C for up to 30 days.

Material And Methods: Original vials of cisplatin injection (1 mg/ml, Teva) were stored at room temperature and subjected to re-piercing after 1, 2, 3, 7, 14, 21, 28 and 30 days following the initial piercing. Cisplatin infusions at nominal concentrations of 0.
