Task: Answer Verification
Input (English): Question: Does sublingual application of liquid nitrendipine result in critical hypotension in healthy volunteers under phosphodiesterase-5 inhibition?
Answer: Sublingual nitrendipine seems to be safe for self-treatment of an anginal attack in patients with stable coronary artery disease, who have taken a phosphodiesterase-5 inhibitor. However, our findings on hemodynamic changes in apparently healthy volunteers have to be confirmed in patients with coronary artery disease.
Output (English): no
