Mechanism and action
Viagra Professional: Sildenafil citrate inhibits PDE5, allowing the cyclic GMP produced during sexual arousal to accumulate in penile tissue, which relaxes the smooth muscle of the penile arteries and increases blood inflow. Pepcid: Famotidine reversibly and competitively blocks histamine H2 receptors on gastric parietal cells, reducing both basal and stimulated gastric acid secretion.

When Pepcid is preferred
Pepcid is approved in adults and children for short-term treatment of active duodenal and gastric ulcer, maintenance therapy of duodenal ulcer, gastro-oesophageal reflux disease, Zollinger-Ellison syndrome and other hypersecretory conditions.
