What should you know about Erectile dysfunction drugs?

Erectile dysfunction pills, known as PDE5 inhibitors, are prescribed for treating erectile dysfunction (ED). Roughly half of all adult males between the while of 40 and 70 have some degree of ED. Around 70% of folks who take PDE5 inhibitors can keep an erection long sufficient to engage in sexual sex.

Despite the vast popularity of PDE5 inhibitors, there are limitations and dangers associated with their use. Though the medicine all paintings similar, some differences can also make some greater appropriate for you than others.


PDE5 inhibitors are used to conquer erectile dysfunction, also called impotence. They can help males achieve and sustain an erection, specifically if the underlying reason is physiological. They may even assist if the motive is psychological via supplying a placebo effect.

All PDE inhibitors paint by using blocking an enzyme referred to as phosphodiesterase kind five (PDE5) within the corpus cavernosum (the spongy indoors of the penis in which most of the blood vessels are located). By inhibiting PDE5, nitric oxide molecules are better able to bind to muscle tissues in the corpus cavernosum, allowing them to loosen up and increase the go with the flow of blood into the penis.

There are 5 PDE5 inhibitors authorized with the aid of the U.S. Food and Drug Administration (FDA) for the treatment of ED:

  • Viagra (sildenafil) tablets
  • Cialis (tadalafil) capsules
  • Levitra (vardenafil) tablets
  • Staxyn (vardenafil) dissolvable pills
  • Stendra (avanafil) tablets

In addition to the logo call versions, there are regular variations of Sildenafil Fildena, Tadalafil Vidalista 60, vardenafil capsules, and vardenafil dissolvable drugs, the generic variations are commonly available at lower prices.

Some PDE5 inhibitors produce other authorized makes use. Sildenafil, as an example, is typically prescribed to deal with pulmonary high blood pressure (high blood strain within the lungs), in which case it’s far bought beneath the logo called Revatio. Tadalafil is likewise used for this cause as Adcirca, as well as for treating benign prostatic hyperplasia (BPH, enlarged prostate).

Before Taking

PDE5 inhibitors no longer paintings for everybody. For example, it does now not paint very effectively for human beings who have sustained harm to the blood vessels or nerves of the penis as a result of prostate surgical procedures, cardiovascular disease, or diabetes. While PDE5 inhibitors may fit at better doses in these instances, different options, such as intraurethral pellet or injectable medicine, can be greater powerful.

As a preferred rule, your healthcare company will pinpoint the motive of ED before prescribing any drug. Doing so can better frame expectancies.

In addition, a cardiovascular workup ought to be performed given that erectile dysfunction can be the primary signal of heart troubles.

Precautions and Contraindications

PDE5 inhibitors work by growing the availability of nitric oxide in the bloodstream. For this cause, PDE5 inhibitors must never be used with any organic nitrate medication that has an identical effect. The mixture can result in a potentially existence-threatening drop in blood strain known as a hypotensive crisis.

People who’ve severe liver or kidney disorders also may want to keep away from PDE5 inhibitors:

  • Cialis, Levitra, Staxyn (the dissolvable form of Levitra), and Stendra must in no way be taken if you have an intense liver impairment (categorized as Child-Pugh Class C).
  • Levitra, Stanxyn, and Stendra are contraindicated in case you are on kidney dialysis.
  • Viagra can be used each in these populations, at the lowest dose of 25 milligrams (mg).


The dosage of ED tablets varies on the type decided on. Each of the medications has different strengths, in addition to exclusive onsets and durations of action. Because they can motivate aspect outcomes, the bottom effective dose is commonly used.

Cialis is the simplest PDE5 inhibitor that can be taken as wanted or in low, everyday doses to gain an erection “on demand.”

As a standard rule, the lowest effective dose has to constantly be used. If you’re unable to reap or preserve an erection at the prescribed dose, speak with your healthcare issuer to peer if growth in dose is secure and affordable.


The dosages of positive PDE5 inhibitors might also want to be adjusted for some human beings. As preferred, any PDE5 inhibitor is contraindicated with alpha-blockers (used for urinary problems with BPH) at better doses.

Adjustments your healthcare issuer would possibly make for you encompass:

  • Viagra: Decrease to 25 mg if taking alpha-blockers, and growth is most effective underneath the path of a practitioner.
  • Cialis: Limit the day-by-day intake to ten mg for slight liver impairment, and five mg if on kidney dialysis.
  • Cialis (each day): Limit to 5 mg per day if you have benign prostatic hyperplasia.
  • Levitra and Staxyn: Decrease to five mg for men over age 65, and increase best below the course of a healthcare company. Decrease to five mg every day, by no means exceeding 10 mg every day when you have slight liver impairment.
  • Stendra: Decrease to 50 mg if taking alpha-blockers, and growth only underneath the direction of a practitioner.

How to Take and Store?

Viagra Fildena 150 is taken on an empty belly. Others PDE5 inhibitors are taken by mouth, without or with meals. Food does not hinder the effectiveness of the drug or the onset or duration of motion.

For men who dislike or are unable to swallow tablets, Staxyn pills provide an opportunity. The pills have a sweet, peppermint taste and dissolve fast while positioned on the tongue.

PDE5 inhibitors are saved correctly at or around 77°F (25°C). Short-time period exposure to temperatures of fifty nine° F to 86°F (15° C to 30°C) may not damage the drug, however, by no means keep them for your glove compartment or in direct daylight. It is nice to keep the medicine in their authentic packing containers or blister packs until use. Never use expired capsules.

Never take more than the most advocated dose or take two exclusive PDE5 inhibitors to “improve” their results. This will increase the danger and/or severity of side results.

Side Effects

All PDE5 inhibitors are normally well tolerated. Because they have comparable mechanisms of motion, they have several identical facet effects. Most of the side consequences are slightly achievable, even though a few require terminating treatment and immediate medical attention.

Common facet effects of PDE5 inhibitors consist of:

  • Headache
  • Dizziness
  • Flushing
  • Upset belly
  • Nasal congestion
  • Muscle aches
  • Nausea (especially with Viagra and Levitra)
  • Backache (in particular with Cialis, Staxyn, and Stendra)
  • Bluish visible disturbances (in particular with Viagra)
  • The incidence and severity of facet outcomes tend to grow with the dose. If taken in excess, PDE5 inhibitors can cause a fast drop in blood pressure and syncope (fainting).

Several uncommon side effects are particularly excessive and might require emergency intervention.

Among them:

Priapism (chronic and painful erections) is a common subject with all ED drugs. If an erection lasts longer than 4 hours, are seeking pressing care.

Sudden vision loss can be associated with a circumstance called non-arteritic anterior ischemic optic neuropathy (“eye stroke”), a situation that has been known to affect a small wide variety of individuals who use ED drugs.10 Emergency care is vital in the case of an unexpected loss of imagination and prescient in a single or each eye.

Sudden hearing loss has been mentioned as a probable facet impact of PDE5 inhibitors. Eleven Seek medical interest if there may be a sudden lower or lack of listening in a single or both ears.

The motive for the listening to loss in users of PDE5 inhibitors is unknown, and Viagra seems to pose the greatest danger.

Warnings and Interactions

PDE5 inhibitors are in most cases excreted in feces and, to a lesser degree, in urine. Because of their feasible effect on the liver and kidneys, hepatic (liver) function and renal (kidney) function can be evaluated before the beginning of treatment, especially if you are prone to liver sickness or kidney disease.

Due to the threat of imaginative and prescient loss, people with a circle of relatives records of hereditary eye sicknesses (which includes color blindness, corneal dystrophy, or retinoblastoma) and people with a previous history of eye stroke have to now not take PDE5 inhibitors.

Drug Interactions

Even past contraindicated natural nitrates, there is an intensive listing of medicinal drugs and materials which can interact with PDE5 inhibitors.

Among these, alpha-blockers and antihypertensive drugs need for used with excessive caution because of the hazard of severe hypotension. If the doses aren’t separated by using 24 hours (or 48 hours with Cialis), an excessive hypotensive occasion might also occur. Guanylate cyclase stimulators (nitric oxide receptors) pose similar risks.

Even alcohol can reason a brief drop in blood stress if excited about a PDE5 inhibitor. This is specifically true with Cialis (in component because the drug remains in the device for some distance longer than the alternative ED drugs).

There is not any one PDE5 inhibitor that is inherently better than the others. Often, a practitioner will prescribe Viagra to first-time customers, in component because of call reputation and fee. But, the easy reality is that others may match simply as nicely, if no longer higher, and provide fewer facet results. You often may not recognize it until you attempt several outs.

When discussing together with your healthcare company which drug to use, make certain they recognize any liver or kidney troubles you have, what capsules you’re taking (each prescription or over-the-counter), and in case you’ve been recognized with an eye fixed or cardiovascular disease.

The extra a healthcare provider knows approximately your fitness, the more likely they may be to discover the drug and dose that is simply proper for you.
