<p class="MsoNormal">Men who are unable to achieve or maintain an erection typically use the inexpensive medication Cenforce pills. Its primary component is the phosphodiesterase type 5 (PDE5) inhibitor sildenafil citrate. PDE5 inhibition helps increase blood flow to the penis, which aids in erection maintenance for men with ED during sexual activity. Cenforce is produced by Centurion Laboratories and is taken orally as a tablet. It is usually taken 30 to 60 minutes before engaging in sexual activity and should not be taken more than once a day. It should not be used by women or children, and it should only be taken under the supervision of a medical professional.
