Each film-coated tablet contains:

Composition:
Sildenafil Citrate...............................................................50 mg

Indications : NEOGRA is indicated for the treatment of erectile dysfunction in men.

Description:
Part of the physiological process of erection involves the parasympathetic nervous system causing the release of nitric oxide (NO) in the corpus cavernosum of the penis. NO binds to the receptors of the enzyme guanylate cyclase which results in increased levels of cyclic guanosine monophosphate (cGMP), leading to smooth muscle relaxation (vasodilation) in the corpus cavernosum, resulting in increased inflow of blood and an erection.
Sildenafil is a potent and selective inhibitor of cGMP specific phosphodiesterase type 5 (PDE5) which is responsible for degradation of cGMP in the corpus cavernosum. The molecular structure of sildenafil is similar to that of cGMP and acts as a competitive binding agent of PDE5 in the corpus cavernosum, resulting in more cGMP and better erections. Without sexual stimulation, and therefore lack of activation of the NO/cGMP system, sildenafil should not cause an erection. Sildenafil is metabolised by hepatic enzymes and excreted by both the liver and kidneys. If taken with a high-fat meal, there may be a delay in absorption of sildenafil and the peak effect might be reduced slightly as the plasma concentration will be lowered

Contraindications
Use of NEOGRA is contraindicated in patients with a
known hypersensitivity to any component of the tablet.
Consistent with its known effects on the nitric oxide/cGMP
pathway, sildenafil was shown to potentiate the hypotensive
effects of nitrates, and its administration to patients who
are concurrently using organic nitrates in any form is
therefore contraindicated.

Dosage:
For most patients, the recommended dose is 50 mg taken, as needed approximately 1 hour before sexual activity. However, NEOGRA may be taken anywhere from 4 hours to 0.5 hour before sexual activity. Based on effectiveness and toleration, the dose may be increased to a maximum recommended dose of 100 mg or decreased to 25 mg. The maximum recommended dosing frequency is once per day.
