Intramuscular depot formulations of leuprolide acetate suppress testosterone levels below a 20 ng/dL threshold: a retrospective analysis of two Phase III studies.

Introduction: Androgen deprivation therapy (ADT) with gonadotropin-releasing hormone (GnRH) analogs is a standard treatment for advanced prostate cancer. GnRH analog therapy can reduce testosterone to "castrate" levels, historically defined as <50 ng/dL. With the advent of newer assays, a lower threshold of <20 ng/dL has recently been proposed.

Integrating diet and exercise into care of prostate cancer patients on androgen deprivation therapy.

Improved diagnosis and treatment regimens have resulted in greater longevity for men with prostate cancer. This has led to an increase in both androgen deprivation therapy (ADT) use and duration of exposure, and therefore to its associated adverse effects, such as sexual dysfunction, osteoporosis, reduced muscle mass, increased fat mass, and increased incidence of cardiovascular disease and type 2 diabetes. Given that the adverse effects of ADT are systemic, often debilitating, and difficult to treat, efforts continue in the development of new strategies for long-term management of prostate cancer.

Six-month leuprorelin acetate depot formulations in advanced prostate cancer: a clinical evaluation.

For nearly three decades, gonadotropin-releasing hormone (GnRH) agonists, particularly leuprorelin acetate (LA), have served as an important part of the treatment armamentarium for prostate cancer. The introduction of LA depot formulations provided a significant improvement in the acceptance of this therapy; however, their indicated treatment duration of 1 to 4 months was still not long enough to satisfy all medical needs. For this reason some manufacturers developed new injectable formulations that provide testosterone suppression for 6 months.

Safety and tolerability of intermittent androgen deprivation therapy: a literature review.

Androgen deprivation therapy is commonly used in men with advanced prostate cancer; however, it is associated with many short- and long-term side-effects. Intermittent androgen deprivation therapy was first suggested as an alternative regimen in the early 1990s and is now part of treatment guidelines as a result of its ability to reduce adverse events associated with continuous androgen deprivation therapy without decreasing its efficacy. Although many publications evaluated intermittent androgen deprivation therapy's efficacy, the safety and tolerability information of this regimen is relatively limited.
