The major issue with active pharmaceutical ingredients (APIs) is their slow dissolution rate and solubility. This makes them less likely to get into the body bioavailable. About 40 % of drugs already on market 90 being made have APIs that do not dissolve well in water. To deal this problem, authors designed eutectic mixture (EMs) different (danazol, griseofulvin, mefenamic acid, tolfenamic acid...

The inclusion of certain polymers within solid dispersion or lipid-based formulations can maintain drug supersaturation after dispersion and/or digestion of the vehicle, leading to improvements in bioavailability and variability in exposure. This review presents an overview of the fundamental principles that underpin drug precipitation mechanisms, describes the mechanisms by which precipitation...

OBJECTIVE Immune thrombocytopenic purpura (ITP) is also known as idiopathic thrombocytopenic purpura. Increased platelet destruction and insufficient platelet production are both responsible for its etiopathogenesis. ITP can be diagnosed after excluding other possible causes of thrombocytopenia. MATERIALS AND METHODS One hundred forty-three cases of chronic ITP that were monitored in a hemato...

Prof Şinasi Özsoylu, MD, Department of Pediatrics, Hematology Unit, Faculty of Medicine, Hacettepe University, Ankara 06100 (Turkey) I have read with interest the article by Mazzucconi et al. [1] entitled ‘Danazol Therapy in Refractory Chronic Immune Thrombocytopenic Purpura’ in the recent issue of the journal. I would like to bring to the authors’ attention that marked improvement of platelet ...

-Gonadotrophins, oestradiol, androstenedione, testosterone and dehydroepiandrosterone sulphate (DHAS) were measured sequentially in 72 patients with advanced breast cancer receiving endocrine therapy of various types. Tamoxifen significantly reduced gonadotrophins but did not effect other hormones. Danazol also reduced gonadotrophins. Aminoglutethimide (AGT) reduced oestradiol and DHAS but had ...
