Life after the women's health initiative: evaluation of postmenopausal symptoms and use of alternative therapies after discontinuation of hormone therapy.

STUDY OBJECTIVE: To determine the number of women who have menopausal symptoms after discontinuing hormone therapy, to determine how many of these women subsequently require nonhormonal alternatives to manage their symptoms, and to assess the effectiveness of those therapies. DESIGN: One-year retrospective study. SETTING: Department of Family Medicine outpatient clinic at a university medical center. PATIENTS: From 378 postmenopausal women who discontinued hormone therapy between August 1, 2002, and August 31, 2003, we randomly selected 78 using electronic medical records to provide a sample with a 95% confidence interval and a 10% margin of error. MEASUREMENTS AND MAIN RESULTS: Reasons why the women discontinued therapy and any nonhormonal alternative therapies that they may have used to manage subsequent menopausal symptoms were recorded. The primary investigator contacted the 78 women to complete a telephone survey. In most women, at least one menopausal symptom recurred. Vasomotor symptoms (hot flashes) were most common and occurred in 41 (53%) women. In addition, 59 (76%) women reported using nonhormonal alternative therapies, and 40 (68%) of this group deemed the alternatives helpful. CONCLUSION: We strongly believe that health care providers, including pharmacists, must continue to communicate with and educate women regarding treatment options for menopausal symptoms. Clinical pharmacists are ideally suited to contribute to ongoing research in this area.

Parathyroid hormone (1-84) and treatment of osteoporosis.

OBJECTIVE: To present the chemistry, pharmacology, and pharmacokinetics of parathyroid hormone (PTH) (1-84) and review the available clinical trials that evaluate its efficacy and safety; clinical applicability of this agent and its relationship to other Food and Drug Administration (FDA)-approved medications for treatment of osteoporosis are also discussed. DATA SOURCES: A MEDLINE search (1996-December 2004) was completed, along with a review of information obtained from the manufacturer, NPS Pharmaceuticals. Key search terms included parathyroid hormone, PTH (1-84), and ALX 111. STUDY SELECTION AND DATA EXTRACTION: Studies were selected based on their relevance and availability. Pertinent information, including objectives, design, demographics, outcomes, adverse events, dosing strategies, and therapeutic controversies, was extracted. DATA SYNTHESIS: PTH (1-84) is being developed for treatment of osteoporosis. Recent studies have shown that, when administered intermittently as a subcutaneous injection, PTH (1-84) produces an increase in bone mineral density and prevents vertebral fractures. The fact that this agent contains the C-terminal region of PTH may differentiate it from PTH (1-34), teriparatide, which is approved by the FDA for treatment of osteoporosis. Further trials are necessary to determine the role of PTH (1-84) in combination with other treatments for osteoporosis and/or the order in which PTH (1-84) is given with these other agents. There are currently no comparative trials with other osteoporosis treatment modalities. CONCLUSIONS: PTH (1-84), when given intermittently as a subcutaneous injection, appears to be a safe and efficacious treatment option for osteoporosis. Further trials are needed to determine its specific place in therapy compared with other treatment options.

Azithromycin and warfarin interaction.

A 57-year-old Caucasian woman came to the clinic with symptoms of an upper respiratory tract infection. She was treated with a 5-day course of oral azithromycin 500 mg on day 1, then 250 mg/day for 4 days. During this period, the patient decreased her cigarette smoking from 1 pack/day to 1 pack every 3 days. No additional confounding variables were present. Two days after the completion of therapy, her international normalized ratio (INR) was 8.32. Six case reports documented in the literature have suggested an azithromycin-warfarin interaction with a resultant increase in INR. Many confounding variables existed in each of these cases, such as hepatic dysfunction, poor appetite, and concomitant drugs that resulted in an increased anticoagulant response. We report a case that involved only one potential confounding variable. Continued documentation of azithromycin-warfarin interactions is valuable considering no mention of this drug interaction exists in most tertiary references and in the package insert for azithromycin, the demonstration that no drug interaction occurred in a retrospective review of 52 cases, and the widespread use of azithromycin in the community. Clinicians should be mindful when prescribing azithromycin in combination with warfarin, and INR values should be monitored.
