Sildenafil Lozenges (Generic Viagra ) – 75mg 30tab – $199 Buy
Sildenafil rapid-dissolve lozenges have gained much attention as an effective treatment for erectile dysfunction. These lozenges disintegrate and dissolve in the mouth or beneath the tongue within 15-20 minutes.
PDE5 inhibitors like sildenafil, tadalafil, and vardenafil are first-line treatments for erectile dysfunction. PDE5 inhibitors work by inhibiting the breakdown of cyclic guanosine monophosphate (cGMP) in the smooth muscle of the penis. PDE5 inhibitors in the form of lozenges are not commercially available and can only be made by a compounding pharmacy.
Sildenafil Lozenges – Rapid Onset
Fast-acting sildenafil lozenges promote quick absorption and rapid onset. Sildenafil lozenges kick in faster than their tablet counterpart, in as little as 15 minutes. Since the lozenges are dissolved under the tongue they start working much faster than a tablet that has to pass through the digestive system. A sublingual dosage form is not as effected by food ingestion as the orally administered tablets.
Studies have shown that sublingual sildenafil is safe and effective. In one study, sixty‐five percent of patients (13/20) who received sublingual sildenafil achieved satisfying erections and coitus, whereas the rate was 15% in the placebo group (3/20). Minimal side effects were noticed and included headache, sweating, and flushing.
Sildenafil (Oral Route)
Sildenafil is used to treat men who have erectile dysfunction (also called sexual impotence). Sildenafil belongs to a group of medicines called phosphodiesterase 5 (PDE5) inhibitors. These medicines prevent an enzyme called phosphodiesterase type-5 from working too quickly. The penis is one of the areas where this enzyme works.
Erectile dysfunction is a condition where the penis does not harden and expand when a man is sexually excited, or when he cannot keep an erection. When a man is sexually stimulated, his body’s normal response is to increase blood flow to his penis to produce an erection. By controlling the enzyme, sildenafil helps to maintain an erection after the penis is stroked. Without physical action to the penis, such as that occurring during sexual intercourse, sildenafil will not work to cause an erection.
Sildenafil is also used in both men and women to treat the symptoms of pulmonary arterial hypertension. This is a type of high blood pressure that occurs between the heart and the lungs. When hypertension occurs in the lungs, the heart must work harder to pump enough blood through the lungs. Sildenafil works on the PDE5 enzyme in the lungs to relax the blood vessels. This will increase the supply of blood to the lungs and reduce the workload of the heart.

Before Using
