Abstract:
Fulvestrant is a selective estrogen receptor downregulator, behaving as a complete antagonist. It was initially approved, at a dose of 250 mg, to treat hormone dependant breast cancer in second line setting. However, a series of pharmacological and pre-clinical studies have suggested that a higher dose of 500 mg may be more effective. The present work summarizes and discusses clinical trials that have aimed to test the benefits of administering fulvestrant at a higher dose. The data support the use of a higher, and more possibly, effective dose of the agent.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
