ClinicalTrials.gov Identifier:
NCT00002146
First received: November 2, 1999
Last updated: June 23, 2005
Last verified: January 1997
  Purpose

To determine whether acute ionized hypomagnesemia and hypocalcemia immediately following foscarnet infusions can be lessened or eliminated by prior infusion of magnesium sulfate. To determine whether reductions in ionized magnesium, ionized calcium, and parathyroid hormone levels following foscarnet infusions are lessened by preinfusion of magnesium sulfate. To evaluate the safety of intravenous magnesium sulfate prior to foscarnet infusion by monitoring blood pressure, heart rate, and heart rhythm. To characterize the effect of magnesium sulfate on foscarnet blood levels and urinary excretion of calcium, magnesium, phosphate, and foscarnet.

Estimated Enrollment: 12
Detailed Description:

Patients are randomized to one of four treatment groups. Intravenous foscarnet is administered for 4 days. Patients receive one of three doses of magnesium sulfate or placebo in normal saline according to one of four schedules. Sequence of doses will differ for each group.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
