Plain English Summary
Background and study aims
Pre-eclampsia is a potentially serious condition affecting pregnant women, usually during the second half of pregnancy or just after the baby is born. Symptoms include high blood pressure, protein in the urine, swelling of feet, ankles, face and hands, severe headache, vision problems and pain experienced below the ribs. If not treated, eclampsia may develop. Eclampsia is a type of fit, or seizure. This carries with it a small risk of permanent disability or brain damage if the fits are severe. Women with pre-eclampsia can prescribed magnesium sulphate. This drug can help prevent seizures in women with severe pre-eclampsia and decrease them in women with eclampsia. Drugs can been absorbed, distributed, metabolised and excreted (removed) by the body differently according to how it is given to the patient. This is called the drug pharmacokinetic profile. This study is looking at the pharmacokinetics profile of magnesium sulphate (MgSO4) given directly into the muscle (intramuscular) compared to the drug given into a vein (intravenous).
Who can participate?
Patients with preeclampsia from Subang District Hospital.
What does the study involve?
Participants are randomly allocated into one of two groups. Those in group 1 are given an initial MgSO4 “loading dose” (higher starting dose) intravenously (IV) followed by a IV maintenance dose. Those in group 2 are given a IV plus intramuscular (IM) loading dose followed by a IM maintenance dose that is given every 4 hours. The therapy in both groups are stopped at 24 hours. Blood samples are collected at the start of the treatment and then after 10 minutes, 1 hour, 2 hours, 4 hours, 24 hours, 26 hours, 28 hours, and finally 30 hours after treatment begins. Serum magnesium level are determined in the laboratory. The pharmacokinetics profiles of magnesium for each group are obtained and compared.

Intervention
A total 70 pregnant women with pre-eclampsia were involved in this study. Subjects were divided into two groups with 35 subjects in each group. The intravenous group received an IV loading dose of MgSO4 solution, followed by a maintenance IV regimens of MgSO4. The intramuscular group received an IV loading dose MgSO4 solution, followed by a IM regimens of MgSO4. Serial blood samples were collected at 0; 10 min; 1; 2; 4; 24; 26; 28 and 30 h. The serum Mg concentrations were determined using the atomic absorption spectrophotometer method. Pharmacokinetics parameters including peak serum concentration (Cmax), time to reach peak concentration (Tmax), the area under the serum concentration versus time curve going to infinity (AUCo-∞) and elimination half-life (t1/2), elimination rate constant (kel), clearance (Cl), and volume of distribution (Vd) were calculated using standard methods and compared between groups.
