Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
Q: Abstract: The pharmacokinetics of oral and intravenous bromide was studied in 7 adult volunteers, who served as their own controls. They received 1 ml/kg of 3% sodium bromide, equivalent to 30 mg/kg bromide. Oral bioavailability ranged between 75-118% with a mean of 96 +/- 6%. Elimination T1/2 was 11.9 +/- 1.4 days after oral administration and 9.4 +/- 1.5 days after I.V. administration (P greater than 0.10). The employment of this ion for calculation of extracellular fluid and assessment of its potential significance in environmental toxicology necessitates accurate data on its disposition characteristics.
Which is the apt title for the abstract? option1: Pharmacokinetics of oral and intravenous bromide in normal volunteers. option2: Toluidine blue in the detection of perineal lacerations in pediatric and adolescent sexual abuse victims.
A:
Pharmacokinetics of oral and intravenous bromide in normal volunteers.
