Tastylia 20 mg is a brand of medication that contains tadalafil as its active ingredient. Tastylia 20 mg is unique in that it is available in the form of oral strips that dissolve on the tongue. These strips are designed to be more convenient for administration compared to traditional tablets. Tadalafil works by inhibiting the enzyme PDE5, which regulates blood flow in the penis. By inhibiting PDE5, tadalafil increases blood flow to the penis during sexual stimulation, which helps men achieve and maintain an erection suitable for sexual activity. Tadalafil has a longer duration of action compared to other PDE5 inhibitors, lasting up to 36 hours after ingestion. This allows for greater spontaneity in sexual activity.
