Mechanism and action
Allegra: Fexofenadine selectively blocks peripheral H1 histamine receptors, antagonising the effects of histamine on vasodilation, capillary permeability, sensory nerve endings and smooth muscle. Kamagra Oral Jelly: The active sildenafil citrate inhibits PDE5 in penile tissue, allowing the cyclic GMP produced by sexual arousal to accumulate, relaxing the smooth muscle of penile arteries and increasing blood inflow.
When Allegra is preferred

When Kamagra Oral Jelly is preferred
