- increase milk let down (mastitis)
- helps stop uterine bleeding (useful after parturition or after caesarian)
- reposition of uterine prolapse
- help with retention of foetal membrane and eggs
list the side effects associated with oxytocin?

- CV-system
- swelling at inj. site
name the veterinary oxytocin drugs available?
oxytocin inj.
oxytocina inj.
oxytocine inj.
Dila-part inj.
Perilacton nasal spray
What is Carbetoin?
synthetic anologue of oxytocin
much longer half life (once daily inj.)
describe Ergometrine?
potent uterine stimulant
Rarely used during parturition
Post-partum (haemorhage, retained placenta) promotes the expulsion of the contents of the uterus
describe the use of Methylergometrine?
same as ergometrine but without the vasoconstrictive activity
name the Myometrial relaxants?
B2-adrenoceptor agonists
Antispasmodics
Name the B2 - adrenoceptor agonists used as myometrial relaxants?
Clenbuterol
Terbutaline
name the anti-spasmodics used as myometrial relaxants?
Papaverine
Drotaverine
Denaverine
list the indications for the use of myometrial relaxants?
- inhibition of premature labour
- difficult labour - when malpresentation correction is required
- intrauterine foetal procedure
- Reposition of uterus
- procurement of embryos from donors, and implantation into recipients
describe the action of myometrial relaxants?
inhibit the action of oxytocin
name the anticholinergic substance that can be used as a myometrial relaxant?
Atropine
Name the side effects of prostaglandins?
colic like disorders
Nausea
Vomiting
diarrhoea
bronchoconstriction
