In Singapore, Viagra is on the list of the most popular and sold drugs for effective recovery of male potency. Viagra is manufactured and supplied to the pharmaceutical market of Singapore by the world famous company Pfizer.

The clinical effect of Viagra tablets lies in the restoration of male potency and the ability to achieve or maintain a strong long-lasting erection. Viagra exerts its therapeutic effect by:
- increasing the concentration of the enzyme guanylate cyclase;
- accelerating the synthesis of nitric oxide (NO) in penile tissues;
- restoring the blood circulation in the male genitalia.
Viagra helps to relax the cavernous muscles of the penis, as well as to accelerate its filling with blood. However, sexual stimulation is required to get a sufficient erection while using Viagra.
Viagra should be used only orally, according to the situation. To get a strong erection, Viagra tablets should be taken approximately one hour before the expected sexual intercourse. The maximum frequency of Viagra use is one tablet within 24 hours.
- Viagra tablets are recommended to be taken whole, without chewing or dividing into two or more parts;
- Viagra film-coated tablets should be washed down with a sufficient amount of clean water;
- orodispersible Viagra tablets quickly dissolve on the tongue, and can be taken without water;
- fatty foods can slow down the absorption of Viagra tablets, and slightly delay the onset of their therapeutic effect.
Viagra tablets are intended only for adults over 18 years of age, whom sexual activity is not contraindicated. Men with some cardiovascular diseases (e.g., coronary heart disease) are contraindicated to sexual acts, and the use of Viagra is not appropriate.
The initial dose of Viagra, recommended for most men to restore potency, is 50 mg/day. Where the use of Viagra 50 mg does not help to get a strong erection, you can use the maximum daily dose equal to 100 mg as an alternative.
If the initial dose of Viagra helps restore a man’s potency, yet causes adverse reactions, it is recommended to take the initial dose of this drug to treat ED at a rate of 25 mg/day.
Viagra can cause dose-depended short-term adverse reactions, in particular flushing, increased blood pressure or headaches. The list of the least common undesirable phenomena of Viagra includes rhinitis, nasal congestion, dyspepsia, drowsiness, nausea, and visual disturbances.
The minimum dose of Viagra 25 mg may be appropriate for men with severe liver or kidney disease, geriatric patients with ED, as well as in concomitant use with drugs, used for:
- blood pressure lowering (Methyldopa, aka Aldomet)
- treatment of benign prostatic hyperplasia (Terazosin, also called Hytrin)
- treatment of infectious diseases, caused by bacteria (Erythromycin, produced under the brand E-Mycin)
- pharmacotherapy or prophylaxis of HIV and/or AIDS (Saquinavir, also popular as Invirase)
In simultaneous use of high Viagra doses with Ritonavir (Norvir), the risk of drug interaction increases significantly. To avoid hypertension, take Viagra 25 mg not earlier than two days after the use of this antiviral medication.
Men, who want to learn more about the recommendations for the use of this drug for the ED treatment, can consult a pharmacist while purchasing Viagra in a Singaporean pharmacy.
