The most common sexual issues in males with diabetes are problems with erections and ejaculation: "With diabetes, blood vessels supplying the peniss erectile tissue can get hard and narrow, preventing the adequate blood supply needed for a firm erection. The nerve damage caused by poor blood glucose control can also cause ejaculate to go into the bladder instead of through the penis during ejaculation, called retrograde ejaculation. When this happens, semen leaves the body in the urine." Another cause of erectile dysfunction is reactive oxygen species created as a result of the disease. Antioxidants can be used to help combat this. Sexual problems are common in women who have diabetes, including reduced sensation in the genitals, dryness, difficulty/inability to orgasm, pain during sex, and decreased libido. Diabetes sometimes decreases estrogen levels in females, which can affect vaginal lubrication. Less is known about the correlation between diabetes and sexual dysfunction in females than in males.Oral contraceptive pills can cause blood sugar imbalances in women who have diabetes. Dosage changes can help address that, at the risk of side effects and complications.Women with type 1 diabetes show a higher than normal rate of polycystic ovarian syndrome (PCOS). The reason may be that the ovaries are exposed to high insulin concentrations since women with type 1 diabetes can have frequent hyperglycemia.
Bosutinib (rINN/USAN; codenamed SKI-606, marketed under the trade name Bosulif) is a small molecule BCR-ABL and src tyrosine kinase inhibitor used for the treatment of chronic myelogenous leukemia. Originally synthesized by Wyeth, it is being developed by Pfizer. Mechanism
It is an ATP-competitive Bcr-Abl tyrosine-kinase inhibitor with an additional inhibitory effect on Src family kinases (including Src, Lyn and Hck). It has also shown activity against the receptors for platelet derived growth factor and vascular endothelial growth factor. Bosutinib inhibited 16 of 18 imatinib-resistant forms of Bcr-Abl expressed in murine myeloid cell lines, but did not inhibit T315I and V299L mutant cells.Bosutinib is metabolized through CYP3A4. Medical uses
Bosutinib received US FDA and EU European Medicines Agency approval in September 2012, and March 2013, respectively for the treatment of adults with Philadelphia chromosome-positive (Ph+) chronic myelogenous leukemia (CML) with resistance, or intolerance to prior therapy. Contraindications
Bosutinib has two known absolute contraindications, which are: known hypersensitivity to bosutinib and liver impairment. Interactions
Bosutinib is both a substrate and an inhibitor of P-glycoprotein (P-gp) and CYP3A4. Hence P-gp and CYP3A4 inhibitors may increase plasma levels of bosutinib. Likewise CYP3A4 inducers may reduce plasma concentrations of bosutinib. It may also alter the metabolism and uptake (into the GIT by means of its P-gp inhibitory effects) of other drugs that are substrates for P-gp and CYP3A4. Notes
