Viagra is a well known brand name for its main component – the chemical substance called Sildenafil citrate.
Sildenafil citrate was originally designated to fight heart disorders, but the researches demonstrated its high efficacy in ED treatment, so it was approved as ED oral therapy. Sildenafil chemical formulation is 1 – [[3 – (6,7 – dihydro – 1 – methyl – 7 – oxo – 3 – propyl – 1H – pyrazolo[4,3 – d]pyrimidin – 5 – yl) – 4 – ethoxyphenyl]sulfonyl] – 4 – methylpiperazine citrate.
The citrate salt of Sildenafil is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5).
The main purpose of Viagra (Sildenafil) is to provide muscle loosening and extra blood flow to the penis in men with erectile problems.
Viagra table is blue, film-coated rounded-diamond-shaped, acceptable in the doses of 25 mg, 50 mg and 100 mg of Sildenafil for oral intake.
Other ingredients of Viagra are: microcrystalline cellulose, anhydrous dibasic calcium phosphate, croscarmellose sodium, magnesium stearate, hypromellose, titanium dioxide, lactose, triacetin.
In addition to the treatment of the underlying cause of ED which can help to enhance the sexual function there are oral ED medications specially designed to fight the problem.
Oral medications help even in severe ED condition and in men that have different ED causes.
Oral ED medications are a successful erectile dysfunction treatment for many men. The most popular oral tablets include:
- Sildenafil (Viagra)
- Tadalafil (Cialis)
- Vardenafil (Levitra)
All three medications are approved by FDA to treat erectile function in men. Viagra became the first oral medication authorized by U. S. FDA to treat impotence. All these oral medications work practically the same way.
These drugs belong to the impotence agents and all are selective inhibitors of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). They enhance the effects of nitric oxide, a natural chemical produced in the human body. This chemical provides muscle relaxation in the penis. This increases blood flow to the penis and helps a person to get an erection in response to sexual arousal. These medications vary in dosage, the time of effect and their adverse reactions. Viagra remains the most popular medication from these oral ED therapies. Doctors usually prescribe Viagra as safe and highly effective medication with practically no or minor side effects. They generally take into consideration the individual situation to adjust the medication which works best.
Not only physical disorders and conditions can influence the ability of men to get and maintain an erection. An erection process is a very complicated one, involving series of physical events and production of chemical substances that cause an erection, beginning with feelings of sexual arousal.
Emotional disturbance, embarrassment and other things can interfere with sexual arousal and result in erectile dysfunction. Psychological causes of ED include:
- Depression, anxiety or other mental health conditions
- Fear of sexual performance because of previous failures
- Relationship problems due family problems, stress at work, poor communication, unsatisfactory sex life and others
In addition to these causes a man with age becomes more concerned about his sexual abilities. Getting older, a person needs more time to achieve erections which may not be as firm as they used to be. Men require more direct touch to the penis to get and keep an erection and this worry them, make them more vulnerable to stress. That is why it is so important to treat psychological ED causes, sometimes counseling and understanding the partner may help to get rid of the problem. It is always advised to consult a specialist for help.
For most males erectile dysfunction cause is usually due to the physical character. Most common ED causes are:
- Diabetes and obesity
- High blood pressure
- Multiple sclerosis
- Heart diseases
- Metabolic condition
- Parkinson’s disease
- Peyronie’s disease or physical deformity of a penis
- Prescription medications
- Kidney failure
- Prostate cancer or enlarged prostate treatments
- Surgeries or injuries that affect the pelvic area or spinal cord
- Tobacco use
- Illicit drugs abuse
Some cases of ED are medically caused, for example some types of prostate or bladder surgery may damage the nerves in the penile area and thus cause impotency. Radiation therapy and any types of surgery in the genital area may also result in erectile problems.
Erectile dysfunction is a medical term for more common in use – male impotence. It is defined like the inability to get and sustain erections rigid and prolonged enough for sexual intercourse. When a male has erection troubles sometimes it isn’t a reason for worry. Still if erectile dysfunction is an existing problem, causing embarrassment, stress and relationship problems it should be considered a medical condition which requires professional medical help.
For most men it is very hard or even impossible to discuss with a doctor erectile dysfunction problem. Problems with erectile function can be signs of other health conditions which demand serious treatment, such as heart disease or uncontrolled sugar in blood (diabetes). In many cases the treatment of the underlying cause is sufficient to restore erectile function. If this doesn’t help to fight erectile dysfunction, doctors prescribe special ED medications or other direct treatment methods.
The condition may cause different unpleasant complications such as a poor and unsatisfactory sex life, low self-conscious, relationship difficulties, stress and fear of sexual performance and the inability to become parents.
It is usually so when a male experiences persistent problems with erections to see a family doctor or a general practitioner. Some males prefer consulting with a specialist – urologist who specializes in male genital problems.
