VigRX is a dietary supplement marketed as a male enhancement product. It contains a blend of herbal extracts, amino acids, and minerals intended to support sexual health. The supplement is claimed to improve erectile function and libido without requiring a prescription. The proposed therapeutic role involves enhancing blood flow to the corpora cavernosa through vasodilatory pathways. Key ingredients such as l-arginine and horny goat weed are thought to increase nitric oxide production, which relaxes smooth muscle. This leads to greater penile engorgement and sustained erections during sexual stimulation. The combined pharmacological actions result in modest improvements in erectile quality through systemic vascular effects.

VigRX is a topical formulation designed to enhance male sexual function. Its therapeutic role centers on facilitating erection by supporting penile blood flow. The active ingredients commonly include herbal extracts and vasodilatory compounds that target smooth muscle relaxation. These compounds interact with nitric oxide pathways to increase cyclic guanosine monophosphate levels and promote endothelial relaxation. By enhancing blood vessel dilation, the preparation aims to improve erectile rigidity and duration. The overall pharmacokinetic effect relies on transdermal absorption into the local tissue environment to achieve targeted vascular response.
