[Buprenorphine in pregnancy].
The treatment of opioid dependence during pregnancy is a major challenge for doctors, social workers and gynaecologists. Continuous drug abuse during pregnancy can lead to a variety of complications in the mother, fetus and neonate. lt is recommended practice to maintain pregnant opioid-dependent women with synthetic opioids and according to international guidelines, methadone is the recommended substance so far. However, a neonatal abstinence syndrome (NAS) of varying severity is observed in 60 - 80 % of the neonates with even a longer course of duration in comparison to the NAS after heroin consumption during pregnancy. NAS is characterised by tremor, irritability, hypertonicity, vomiting, sneezing, fever, poor suckling, and sometimes convulsions. Recent studies have investigated the safety and efficacy of other synthetic opioids like sublingual buprenorphine for the treatment of pregnant patients. We present a 22 year old opioid-dependent woman, who has been maintained continuously on buprenorphine for 3 years. During the treatment episode she delivered two healthy newborns and both did not show any symptoms of NAS. The maintenance therapy with buprenorphine proved safety and efficacy during pregnancy, the mother was free of continuous heroin abuse, verified through supervised urine-toxicology. The quantitative and qualitative difference in NAS may be explained by the partial mu-receptor agonist and kappa-antagonist receptor profile of buprenorphine compared to pure mu-agonist action of methadone or heroin.
