Title
(EN) PREPARATIONS FOR ORAL ADMINISTRATION
(FR) PREPARATIONS ADMINISTREES PAR VOIE ORALE
Abstract
(EN)
Preparations for oral administration efficacious in treating patients with erectile dysfunction which contain as the active ingredient a drug showing a decrease in the solubility in neutral and alkaline regions and having a cGMP-specific phosphodiesterase inhibitory effect, wherein an acidic substance is employed to promote the release of the drug in the digestive tract and thus the drug effect can be expressed at the early stage after the administration.
(FR)
L'invention concerne des préparations destinées à être administrées par voie orale. Ces préparations sont efficaces dans le traitement de patients atteints de dysérection. Elles contiennent, en tant qu'ingrédient actif, un médicament présentant une solubilité réduite dans les zones neutre et alcaline, ainsi qu'un effet inhibiteur de la phosphodiestérase spécifique à cGMP. On utilise une substance acide pour favoriser la libération de ce médicament dans le système digestif, ledit médicament pouvant ainsi agir peu de temps après son administration.
