BACKGROUND There is relevant between individual variability in paracetamol clearance in young women. In this pooled study, we focused on the population pharmacokinetic profile of intravenous paracetamol metabolism and its covariates in young women. METHODS Population PK parameters using non-linear mixed effect modelling were estimated in a pooled dataset of plasma and urine PK studies in 69 y...

BACKGROUND As part of the Oxford Family Planning Association study, we compared mortality in relation to oral contraceptive use and smoking to highlight the differences between them from the perspective of public health. METHODS The study consisted of 17032 women, aged 25-39 years at entry, recruited between May 1, 1968, and July 31, 1974, who had used oral contraceptives, a diaphragm, or an ...

Combined oral contraceptives, oral hormone replacement therapy and thrombophilias are recognised risk factors for venous thromboembolism in women. The objective of this study was to assess the risk of thromboembolism among women with thrombophilia who are taking oral contraceptives or hormone replacement therapy, conducting a systematic review and metaanalysis. Of 201 studies identified, only n...

To assess the effects of oral contraceptives on anticoagulant treatment the prothrombin times of 12 patients were measured while they were taking both drugs simultaneously and while they were taking only anticoagulants. The mean prothrombin time ratio was significantly higher when patients were taking both drugs than when they were taking only anticoagulants and their doses of anticoagulant wer...

Adverse effects of hormonal contraceptives usually diminish with continued use of the same method. Often, physi- cians only need to reassure patients that these symptoms will likely resolve within three to five months. Long-acting injectable depot medroxyprogesterone acetate is the only hormonal contraceptive that is consistently associated with weight gain; other hormonal methods are unlikely ...

Data on the return of fertility after discontinuing various methods of contraception were collected from among the women taking part in the Oxford-Family Planning Association contraceptive study. Return of fertility was measured as the time taken to give birth to a child. The fertility of both nulligravid and parous women who stopped taking oral contraceptives was initially impaired in comparis...

Holding oral presentations in a university course is perceived as stressful and can increase stress hormone concentrations and state anxiety. In such a naturalistic setting, further attention should be paid to the relationship between psychological and hormonal measures of acute stress, as well as women's intake of hormonal contraceptives as a potential moderating variable. In the present study...

Background and objectives: Hypericum perforatum L., commonly known as St. John’s wort (SJW) from the family Hypericaceae is a famous medicinal plant used to treat mild to moderate depression; so, it might affect the pharmacokinetics of numerous drugs. Due to widespread herb-drug interactions of SJW, this study was designed to review the clinical evidences regarding the...
