What is ED?
ED (erectile dysfunction) refers to a state in which satisfactory intercourse cannot be obtained because an erection is not sufficient, or cannot be maintained, at the time of intercourse.
In Japan, more than ten million people are said to be troubled by ED (erectile dysfunction), and recently people in their 10s and 20s have also been increasing.
Those eligible for ED treatment are mainly the following. If you have any anxiety about erections — “sometimes I just don’t get an erection”, “I’m worried about whether I can get an erection” and the like — that is quite enough to make you eligible for treatment.
People who cannot obtain satisfactory intercourse because an erection is not sufficient, or cannot be maintained, at the time of intercourse
Causes of ED
Causes of ED are broadly considered to fall into 4 types.
Psychogenic ED: caused by mental stress, etc.
This is often seen in relatively young people in their 20s to 40s.
Mental stress (for example, stress at work or within the family, pressure from trying to conceive or trauma from an occasion when intercourse did not go well) becomes the cause, sexual arousal is not transmitted properly and ED results.
Since there is often nothing physically abnormal in psychogenic ED, it can be said that the effect of ED treatment medication appears readily.
Organic ED: caused by vascular or nerve disorders
This is often seen in people in their 50s and older.
Aging and lifestyle-related diseases (diabetes, hypertension, hyperlipidemia, etc.) allow arteriosclerosis (a condition in which the blood vessels harden) to progress, blood no longer flows sufficiently into the corpus cavernosum and ED results.
Taking ED treatment medication improves blood flow, and improvement of ED can be expected.
Mixed ED: multiple factors are involved
This is often seen in people in their 50s and older.
In addition to vascular or nerve disorders, a combination of factors such as mental stress causes ED.
Because the causes vary, we propose a treatment method suited to each patient. ED treatment medication may also be effective.
Drug-induced ED: caused by certain medications
Some medications can be a cause of ED.
If something has changed since you started a new medication, or if you take many kinds or large amounts of medication, please consult with a doctor.
– Medications acting on the central nervous system: psychotropic drugs such as antipyretic and anti-inflammatory analgesics, antidepressants and hypnotic-sedatives
– Medications acting on the peripheral nervous system: muscle relaxants, anesthetics, anticholinergics
– Medications acting on the cardiovascular system: antiarrhythmics, diuretics, antihypertensives, vasodilators, agents for hyperlipidemia
– Medications acting on the gastrointestinal tract: agents for peptic ulcers, anticholinergics, antispasmodics
Types of ED Treatment Medication
We are able to provide a wide range of ED treatment medication — Viagra (sildenafil), vardenafil, Cialis (tadalafil), avanafil, udenafil, etc. — matched to each patient’s wishes.
We select the ED treatment medication that is easiest to use according to the characteristics of each one.
For those who would like to try various ED treatment medications to find what suits them best, we also offer affordable trial sets.
(sildenafil)
Recommended for: people whose erections did not become very hard with other ED drugs
Features: It acts within a short time, and the effect also wears off within a short time.
Food: Taken together with food the effect is halved, so we recommend taking it 30 minutes before a meal.
Time until the effect appears: approx. 30 minutes to 60 minutes
Duration of action: approx. 4 to 5 hours
– People who have tried other ED treatment medication without effect and want to feel the effect soon after taking it
– People who have used Viagra (sildenafil) for a long time, have no side effects and want to continue taking it as it is
– People who want a formulation that can be taken without water (Viagra OD Film)
Recommended for: people who above all want an erection that is quick and hard
Features: Absorption is rapid, it is highly fast-acting, and hardness is the greatest of the 3 types.
Food: There is no problem taking it together with food, but taking it 30 minutes beforehand is more effective. On an empty stomach, the effect begins to appear in approx. 15 minutes.
Time until the effect appears: approx. 20 minutes to 60 minutes
Duration of action: approx. 4 to 6 hours
– People who want to feel the effect of ED treatment medication immediately and want to choose one with strong erectile power
– People who want to maintain an erection as the penetrating partner throughout sexual activity, or who want to prevent loss of erection midway (going soft during penetration)
– People who want to feel the effect right after taking it but may have sexual activity after a meal or alcohol (vardenafil is also affected by food and drinking, but less so than sildenafil)
(tadalafil)
Recommended for: people who do not know at what point in the day they will have sex, and people who often have sex after a meal
Features: Compared with the others, a mild and natural effect can be expected. It acts for a long time and has relatively few side effects.
Food: There is no problem taking it together with food, but it is more effective used on an empty stomach.
Time until the effect appears: approx. 1 to 3 hours
Duration of action: approx. 24 to 36 hours
– People who often have sexual activity after a meal or alcohol
– People whose timing for sexual activity is not fixed and who want to feel the effect whenever sexual activity occurs (while traveling, or when a partner lives far away and the timing cannot be predicted)
– People who are not always the penetrating partner during sexual activity (versatile, receptive, etc.) but who want to have an erection more easily during the act
For tadalafil, “daily therapy” is also available, in which the medication is taken every day regardless of sexual activity.
Recommended for: people who want a quick, hard erection, people who want to take it without worrying about meal times, people who want to feel an effect but are concerned about side effects
Features: Known as the 4th ED treatment medication, it has a strong effect, is less affected by food and has relatively few side effects.
Meals: There is no problem taking it together with food, but it is more effective when used on an empty stomach.
Time until the effect appears: approx. 15 to 30 minutes
Duration of action: approx. 4 to 6 hours
– People who want to feel the merits of both vardenafil and tadalafil while keeping the cost of using ED treatment medication down
– People who want to maintain an erection as the penetrating partner throughout sexual activity, or who want to prevent loss of erection midway (going soft during penetration)
– People who want to feel the effect right after taking it but may have sexual activity after a meal or alcohol (it is less affected by food and alcohol than sildenafil or vardenafil)
Recommended for: people who want to take it without worrying about meal times, people who want to feel an effect but are concerned about side effects
Features: Known as the 5th ED treatment medication, it is the newest ED treatment medication. A mild and natural effect can be expected; it acts within a short time and the effect lasts for a long time. Side effects are also relatively few, and compared with the long-acting Cialis (tadalafil) the time until it acts is shorter, it wears off earlier and the price is lower.
Meals: There is no problem taking it together with food, but it is more effective when used on an empty stomach.
Time until the effect appears: approx. 30 to 60 minutes
Duration of action: approx. 8 to 13 hours
– People who expect a long-lasting effect and also want the effect to come soon after taking it, or who want to keep the cost of using ED treatment medication down
– People who often have sexual activity after a meal or alcohol
– People who are not always the penetrating partner during sexual activity (versatile, receptive, etc.) but who want to have an erection more easily during the act
– People whose timing for sexual activity is not fixed and who want to feel the effect whenever sexual activity occurs (while traveling, or when a partner lives far away and the timing cannot be predicted)
Daily Therapy with ED Treatment Medication
By taking a small amount of tadalafil every day (usually 2.5 to 5 mg) to stabilize the blood concentration, it is possible to obtain the effect of ED treatment medication “at any time” without worrying about the timing of intake.
In addition to stably supporting the onset and maintenance of erections, in those who have ED plus urinary problems (such as benign prostatic hyperplasia), improvement of urinary symptoms can also be expected.
From the link below, you can learn about daily therapy with tadalafil in detail!
– People who have sex frequently
– People who find it hard to predict when they will have sex
– People who are not satisfied with as-needed (on-demand) intake
– People prone to side effects (hot flushes, red eyes, etc.)
– People who want to improve urinary problems (such as benign prostatic hyperplasia) in addition to ED, etc.
Features: By taking it at the same time every day, a steady state is reached in about 5 days. It has the effect of improving ED for sex at any time of the day. Its efficacy for ED is considered comparable to as-needed (on-demand) intake, and daily tadalafil is particularly recommended for ED accompanied by urinary problems.
Meals: There is no problem taking it together with food, but it is more effective when used on an empty stomach.
Time until the effect appears: It is effective from 5 days after starting to take it. It is also possible to use ED treatment medication concurrently during daily tadalafil.
Duration of action: From 5 days after starting to take it onward, it is effective at any time.
