Adverse Reactions
Significant: Increased risk of endometrial, breast, or ovarian cancer; endometrial hyperplasia, breakthrough bleeding and spotting; increased risk of venous thromboembolism (e.g. DVT, pulmonary embolism), ischaemic stroke, dementia; increased endometrial wall thickness; fluid retention; decreased HDL cholesterol, total triglyceride, lipoprotein, total cholesterol and VLDL-C; decreased (very minor) thyroid-binding globulin, total thyroxine, sex hormone-binding globulin (SHBG). Rarely, hypertriglyceridaemia resulting in pancreatitis.
Eye disorders: Visual disturbances (e.g. blurred vision).

Monitoring Parameters
Obtain a complete personal and family medical history prior to therapy; baseline mammography, blood glucose, serum Ca, triglycerides and cholesterol levels, LFTs. Perform routine physical examination that includes blood pressure, breast and pelvic exam, including a Papanicolaou smear; adequate diagnostic measures (e.g. endometrial sampling), if indicated. Monitor glycaemic control in diabetics, lipid profiles in patients with hyperlipidaemia, and thyroid function in patients undergoing thyroid hormone replacement therapy. Assess for signs of endometrial cancer in female patients with a uterus; signs and symptoms of thromboembolic disorders. Evaluate the need for continuation of therapy.
Symptoms: Nausea, vomiting, vaginal bleeding. Management: Symptomatic treatment.
Drug Interactions
Enhanced effect of anticoagulants (e.g. warfarin). May increase metabolism with CYP3A4 inducers (e.g. barbiturates, carbamazepine, hydantoins, rifampicin).
Food Interaction
May induce metabolism with St. John's wort.
Lab Interference
May impair coagulation, lipid, glucose tolerance, corticoid binding globulin, sex hormone-binding globulin, and thyroid function tests.
Description: Tibolone is a steroid that is rapidly converted into 3 active metabolites following administration which possess estrogenic, progestogenic, and androgenic properties. It substitutes for estrogen loss in postmenopausal women, reduces vasomotor symptoms of menopause, and prevents bone loss after menopause or ovariectomy.
Absorption: Rapidly and extensively absorbed. Time to peak plasma concentration: 1-2 hours (tibolone and active metabolites).
Metabolism: Rapidly converted in the gastrointestinal tract and liver into 3 active metabolites, with 2 (3α-OH-tibolone, 3β-OH-tibolone) having predominantly estrogenic property and 1 (delta-4-isomer of tibolone) with progestogenic and androgenic property.
Excretion: Mainly via faeces (as metabolites); partly via urine (as metabolites). Elimination half-life: 6-8 hours (3α-OH-tibolone, 3β-OH-tibolone).
