Stendra est autorisé dans la dysfonction érectile chez l'homme adulte.
When Levothyroxine is used
La lévothyroxine est autorisée dans l'hypothyroïdie de toute cause (thyroïdite de Hashimoto, post-thyroïdectomie, post-iode radioactif, congénitale), dans le goitre et dans la freination de la TSH après cancer thyroïdien différencié.
Mechanisms compared
Stendra: L'avanafil inhibe sélectivement la phosphodiestérase de type 5 dans le corps caverneux, ce qui augmente le GMP cyclique et amplifie la vasodilatation médiée par le monoxyde d'azote en réponse à la stimulation sexuelle. Levothyroxine: La lévothyroxine remplace la thyroxine endogène déficitaire, convertie dans les tissus en hormone active, la triiodothyronine (T3), par les enzymes désiodases.

Comparing Stendra with Levothyroxine makes sense when both are in the same clinical decision: the prescriber has weighed both for different but related conditions. If the question is between two options for the same need, the prescriber decides based on prior response, comorbidities and tolerance.
