Mechanism and action
Clomiphene: Le clomifène bloque les récepteurs des estrogènes au niveau de l'hypothalamus, empêchant le rétrocontrôle négatif normalement exercé par les estrogènes sur la production de gonadolibérine. Ativan: Le lorazépam se lie au site benzodiazépine du récepteur GABA-A et renforce de façon allostérique la conductance chlorure inhibitrice.
When Clomiphene is preferred
Le clomifène est indiqué dans l'induction de l'ovulation chez les femmes présentant une infertilité anovulatoire avec fonction hypophyso-ovarienne intacte, lorsque les autres causes d'infertilité ont été écartées ou prises en charge.
When Ativan is preferred
Ativan est autorisé chez l'adulte dans la prise en charge de courte durée des troubles anxieux et de l'insomnie liée à l'anxiété.
