Doxium (calcium dobesilate) can favourably influence the microcirculation in different pathological conditions. To test its potential effects in pregnancies complicated with pregnancy-induced hypertension (PIH) or pre-eclampsia (PE) a double-blind, placebo-controlled study was carried out. Enrolled 23 patients (gest. age 34 ≤ week) with gestational hypertension (GH) [mean arterial pressure (MAP) > 105 mmHg] daily took 2000 mg of Doxium or placebo onward until delivery. Retrospective analysis revealed that 2 patients in the placebo group (PG) and 8 in the active group (AG) had PE [GH + proteinuria (PU) ≤ 0.5 g/day] at the time of enrollment. Twelve patients received placebo for 52.6 days, and 11 patients took drugs for 57.0 days on average. MAP and PU were determined daily, parameters of renal function, haemorheology and some plasma components were weekly measured. The data collected at the start and at the end of treatment were compared. The biophysical profile of the fetuses, conditions of the deliveries, and the neonatal period were also recorded. The MAP (mean ± SD) significantly decreased from 118 ± 7 to 99 ± 9 mmHg in the AG (p < 0.001), meanwhile in the PG it slightly increased. PU was higher in the AG at the start of medication, however, no significant changes of this parameter were detected throughout the study. Although values of fibronectin decreased significantly in both groups, it was more pronounced in the AG (23.8% vs. 9.4%). Changes of platelet count, plasma and blood viscosity were favourable in the AG and worsened in the PG but none of the alterations were statistically significant. No marked differences were found between the two groups regarding fetal wellbeing, courses of deliveries, and the neonatal period. Neither maternal nor fetal/neonatal side effects were noticed. Doxium seems to be an effective and safe drug in the management of GH. However, further studies are needed to confirm our preliminary results and evaluate its effects on perinatal outcome.
