Answer:
<u>Heroin (opiate)</u> causes euphoria, relaxation, drowsiness, and detachment from reality and has possible effects on the pregnancy, including preeclampsia, intrauterine growth restriction, and premature rupture of membranes.
Explanation:
OPIATES are a group of CNS drugs which include :
1) Heroin.
2) Meperidine.
3) Methadone.
4) Codeine.
5) Buprenorphine.
They act on number of receptors in order to produce their effects especially analgesia.
Heroin can cause following signs and symptoms :
1) Analgesia ( relief from pain ) : by increasing <u>pain tolerance</u> and <u>decreasing pain perception</u>.
2) Euphoria and relaxation : Heroin changes back to morphine in the<u> brain </u>, acts on <u>opiod receptors </u>and produce euphoria and relaxation.
3) Detachment from reality : As the prolonged use of heroin can change the<u> functional level of the brain</u>, it causes detachment from reality.
Effects on pregnancy ( Preeclampsia , intrauterine growth restriction and premature rupture of membranes ) : These effects occur with heroin because it crosses the placental membrane and causes the relaxation ( inhibition of uterine contractions ) and also causes respiratory depression in the newborn. Hence opiates are strongly prohibited in pregnancy.
