Femlyv (Millicent), an orally disintegrating tablet containing ethinyl estradiol and norethindrone acetate, has been approved by the FDA for prevention of pregnancy in females with a body mass index (BMI) ≤35 kg/m². It is the first hormonal contraceptive to become available in an orally disintegrating tablet formulation. Traditional oral and chewable tablets containing ethinyl estradiol and norethindrone acetate in a wide range of doses, including those found in Femlyv, have been available in the US for years.

The primary symptoms of menopause are genitourinary and vasomotor. The genitourinary syndrome of menopause (GSM) includes symptoms such as burning, irritation, dryness, dyspareunia, dysuria, and recurrent urinary tract infection. Vasomotor symptoms (VMS; hot flashes, night sweats) often disrupt sleep.

Intrauterine devices (IUDs) and the etonogestrel implant are the most effective reversible contraceptive methods available. Hormonal oral contraceptives, patches, rings, and injectables are also effective in preventing pregnancy. When used alone, barrier and behavioral methods generally have higher failure rates than other methods (see Table 1). Selection of a contraceptive method is usually based on patient-specific factors and personal preference

The FDA has approved Phexxi (Evofem), a nonhormonal prescription-only vaginal gel containing lactic acid, citric acid, and potassium bitartrate, for prevention of pregnancy. The gel is intended for on-demand contraception; it is not effective when used after intercourse. It was previously approved for use as a vaginal lubricant (Amphora), but was never marketed.

In our article on Bijuva, the oral fixed-dose combination of estradiol and progesterone (Med Lett Drugs Ther 2019; 61:99), Table 1 should have included single-ingredient oral formulations of estradiol and progesterone (see below). They will be added to the table as it appears online, along with medroxyprogesterone (Provera, and generics), another single-ingredient progestin available for use in women with an intact uterus who take systemic estrogen for menopausal symptoms. Taking generic estradiol and progesterone separately may be less convenient than taking Bijuva, but they cost less and allow for more dosing flexibility.

The FDA has approved Bijuva (TherapeuticsMD), a fixed-dose combination of estradiol and progesterone, for oral treatment of moderate to severe vasomotor symptoms (hot flashes) due to menopause in women with an intact uterus. The manufacturer is marketing Bijuva as "the first and only FDA-approved combination of bio-identical estradiol and bio-identical progesterone in a single daily oral capsule".

Intrauterine devices (IUDs) and the etonogestrel implant are the most effective reversible contraceptive methods available. Hormonal oral contraceptives, patches, rings, and injectables are also highly effective in preventing pregnancy. When used alone, barrier and fertility-based methods generally have higher failure rates than other methods.

The primary symptoms of menopause are genitourinary and vasomotor. A thin, dry vaginal lining and thin urethral mucosa can cause vaginal and vulvar burning and irritation, pain during intercourse, and an increased risk of urinary tract infections. Vasomotor symptoms ("hot flashes") cause daytime discomfort and night sweats that may disrupt sleep.

The FDA has approved Duavee (Pfizer), a fixed-dose combination of conjugated estrogens and the new selective estrogen receptor modulator (SERM) bazedoxifene, for treatment of moderate to severe vasomotor symptoms and for prevention of osteoporosis in postmenopausal women with an intact uterus. Bazedoxifene is an estrogen agonist/antagonist with estrogen-like effects on bone and antiestrogen effects on the uterus. It is the second SERM to be approved for prevention of osteoporosis; raloxifene (Evista, and generics) has been available as a single agent for this indication since 1997.

Osteoporosis is characterized by low bone mass with microarchitectural disruption and skeletal fragility that results in an increased risk of fracture. The diagnosis has traditionally been established by bone densitometry, which is generally reported in terms of standard deviations (SD) from mean values in young adults (T-score). The World Health Organization (WHO) has defined normal bone mineral density (BMD) for women as a value within one SD of the young adult mean. Values 2.5 SD or more below the mean (T score -2.5) are defined as osteoporosis. The WHO has developed a computerized model (FRAX) that predicts the 10-year probability of a hip fracture or any other major osteoporotic fracture based on clinical risk factors and BMD at the femoral neck.

The choice of which contraceptive to use may vary from one stage of reproductive life to another. Intrauterine devices (IUDs), progestin implants and sterilization are the most effective contraceptive methods available to women. Hormonal contraceptives, when used correctly, are also highly effective in preventing pregnancy. Barrier and fertility-based methods have the highest rate of failure.

A combination tablet containing estradiol and drospirenone (Angeliq - Berlex) recently became available for treatment of moderate to severe menopausal symptoms in women with an intact uterus. Since the last Medical Letter issue reviewing such devices,1 more continuous glucose monitoring (CGM) systems have become available. Five devices available now, and two expected to be marketed soon, are listed in the table on page 14. The FDA has approved continuous glucose devices only for the observation of glucose trends.

Many drugs are now marketed for treatment of postmenopausal osteoporosis, but questions remain about their use.

Many drugs are now marketed for treatment of post-menopausal osteoporosis (PD Delmas, Lancet 2002; 359:2018). Prevention of this disorder has been complicated by the news that hormone replacement therapy (HRT), which many women have been taking to prevent osteoporosis, increases the incidence of coronary heart disease and that of breast cancer, stroke and pulmonary embolism as well (Medical Letter 2002; 44:78).

When patents expire on brand-name drugs and generic formulations become available, patients and managed care organizations may express a preference for the lower-cost generics. Are they equivalent to the brand-name product?

Many drugs are now marketed for prevention and treatment of postmenopausal osteoporosis. All regimens should include an adequate intake of calcium and vitamin D.

The tables that follow list drugs used for treatment of cancer in the USA and Canada and their major adverse effects. The choice of drugs in Table I is based on the opinions of Medical Letter consultants. Some drugs are listed for indications for which they have not been approved by the US Food and Drug Administration. For most of the cancers listed, surgery and/or radiation therapy are part of the management of the disease. Anticancer drugs and their adverse effects are listed in Table II.

New information about contraceptives continues to become available. The commonly used methods of reversible contraception are listed below.

The commonly used methods of reversible contraception are listed in the table below. Additional information is available in RA Hatcher et al, Contraceptive Technology, 1990-1992, 15th ed, New York:Irvington, 1990.
