How Sildenafil Citrate Works for Erectile Dysfunction: Timing, Dosage & Effects

Erection issues in men come on without warning. What might be initially an intermittent challenge in being firm, can over time become a habit of losing confidence, intimacy and even sexual fulfilment. This is when the majority of men start looking to find a solution, and this is where they usually find the same name again and again: Sildenafil Citrate.

Sildenafil was initially used as an active ingredient in the brand-name Viagra tablet and has since revolutionized the treatment of Erectile Dysfunction. This type of PDE5 inhibitor medicine directly attacks the blood-flow mechanism that leads to erections. However, even with all its history and popularity, a lot of men are still hesitant about it.

Hence questions tend to surface quickly, like

• How do sildenafil citrate tablets help achieve stronger erections?
• How fast and how long do Sildenafil pills last?
• Why are there so many different strengths of this blue pill?
• Can I use a blue pill daily?

Knowing the answers to these questions would enable men to treat erectile dysfunction with Sildenafil Citrate tablet with realistic expectations instead of assumptions.

What are some different causes of erection issues?

Erection does not happen mechanically. It relies on the coordination of multiple systems of the body, including vascular circulation, nerve signals, hormonal regulation and psychological stimulation.

In sexual arousal the brain transmits signals along the spinal cord that activate nerves located in the penile tissues. These signals cause the release of a molecule, nitric oxide, which relaxes the smooth muscles around penile arteries. The muscles relax, and then the blood flow into the erectile chambers rises tremendously.

The penis becomes hard and it increases in size as the blood fills the corpora cavernosa. Meanwhile, the veins that usually drain the penis are further compressed to assist in rigidity.

In case of disruption of any of these parts of the chain, the quality of erection may be affected. 

Common causes include:

• Decreased vascular disease blood flow
• Vascular diabetes type that impacts the nerves
• Hormonal disorders, such as poor testosterone levels
• Chronic Stress or Anxiety
• Lifestyle habits such as alcoholism or smoking

In the case of many men, the greatest contributor is the lack of efficiency in the vascular reaction that helps to hold blood within the penile tissues. 

The Sildenafil Citrate Effect in Neutralizing the Natural Erection Process

To get to know the mechanism of action of Sildenafil Citrate, it is better to consider what occurs once nitric oxide initiates its signalling pathways.

Nitric oxide causes the release of cyclic guanosine monophosphate (cGMP) which relaxes smooth muscle and permits penile arteries to dilate. The erection can be maintained as long as cGMP is active and this causes blood vessels to remain relaxed.

The body however secretes an enzyme called phosphodiesterase type-5 (PDE5). This is an enzyme that slowly decomposes cGMP and makes the blood vessels narrow down once more.

This breakdown can be too rapid in men who have erectile dysfunction, and may also cause the duration or hardness of the erection to be shorter.

Sildenafil acts by suppressing the PDE5 enzyme. It also helps the blood vessels to stay longer in the relaxed state during sexual stimulation by slowing down the process of degrading cGMP.

The outcome is increased blood circulation and increased capacity to retain an erection.

Among the facts that should not be confused is the fact that sildenafil does not produce an erection by itself. The medication will only cause the biochemical process to be triggered, which requires stimulation of the sexual organs.

How fast does Sildenafil Citrate tablet act?

Timing is one of the major issues that men worry about. When one takes sildenafil, the drug should be absorbed by the digestive system and into the bloodstream before it can start to affect the blood vessels.

In a majority of cases, the drug begins to work in 30-60 minutes.

Nevertheless, the rate of this may be influenced by several factors:

• Food intake before dosing
• Metabolic rate
• Liver enzyme activity and age
• Some drugs influence drug metabolism

Use of sildenafil can be delayed in time by as much as 90 minutes when taken after a heavy or high-fat meal, which slows down its absorption.

It is due to this fact that a great number of doctors recommend taking the pill on a relatively empty stomach in instances when quicker action is required. 

How long does the effect of the Sildenafil Citrate tablet last?

The other common question that men pose is the duration of the effect of sildenafil after it takes effect.

Even though the drug can remain functional in the body for several hours, its effective duration of enhancing erection is in the range of four to six hours. At this period, the body is still more sensitive to sexual stimulation as the PDE5 enzyme is still suppressed.

This does not imply that an erection will last for hours. Instead, the body has the capacity to attain and hold the erections with less difficulty in that period in the case of stimulation.

The reason why Sildenafil is available in various strengths

The availability of numerous strengths is one of the aspects of Sildenafil Citrate therapy that tends to create confusion. Tablets are usually produced in 25mg, 50mg and 100mg.

Such strengths are present since men are vastly different not only in their medication metabolism but also in their vulnerability to PDE5-inhibition of the vascular system.

25 mg Strength

The lower dose of 25 mg can be taken into consideration in the case of individuals who are more sensitive to the effects of the medication used or who have medical reasons to be cautious.

Elderly people have a slow rate of drug metabolism because their liver enzyme activity also changes. The initial low dose assists in the determination of tolerance and decreases the chances of experiencing side effects.

Some of these drugs that affect the metabolism of drugs can also render the lower doses of sildenafil citrate tablets like Cenforce 25mg more suitable.

50 mg Strength

In the situation of many men undergoing treatment, Fildena 50mg is a convenient starting point. It offers a compromise of effectiveness and tolerability to a significant proportion of patients.

In case satisfactory erections are achieved at this level without any annoying side effects, then the same strength can be carried on consistently.

100 mg Strength

Where the moderate dose is not good enough to give adequate improvement, the dose can be raised to 100 mg. This increased level gives rise to greater PDE5 inhibition, enabling cGMP to last longer during sexual stimulation.

The use of higher doses such as Kamagra 100mg, results in an elevated likelihood of the occurrence of side effects, hence the gradual and medical adjustments.

Can the Dose Change from One Occasion to Another?

There are men who ask themselves whether they can sometimes increase or decrease their strength based on the situation.

Clinical practice also tends to be individualized in terms of treatment. A man who will react moderately to 50mg may sometimes demand more to achieve a greater effect. Not to be taken more than once in 24 hours and the maximum dosage of Sildenafil Citrate is also within the recommended range.

Consultation with a medical specialist regularly will also assist in identifying the best approach to be used in achieving consistent outcomes.

Common noticeable side effects of Sildenafil Citrate tablet?

Similar to the majority of drugs, that affect blood flow, Sildenafil Citrate may cause side effects in certain patients. Such reactions are normally associated with the dilation of blood vessels of various parts of the body.

Common effects include:

• Headache
• Facial flushing
• Nasal congestion
• Mild dizziness
• Stomach discomfort

The symptoms are mostly temporary and are usually removed as the drug is eliminated from the blood.

When the side effects are frequent and annoying, one can change the dose or time of administration to enhance tolerance.

Why do Sildenafil Citrate tablets fail to respond?

Sildenafil Citrate can be very effective with a good number of men; although this does not apply in all cases. Several physiological systems are involved in the process of erection and medication is applied to only one aspect.

Ineffectiveness can be reduced when:

• Vascular disease is severe enough to restrict blood flow
• Diabetes has greatly impaired the signal of nerves
• Psychological stress gets in the way of sexual stimulation
• Too much alcohol inhibits the nervous system’s reaction

When that happens, treatment of the underlying health problem may take on a significant role in the enhancement of outcome. 

Generic Sildenafil Citrate tablet vs the Viagra

There are also a lot of men who doubt their generic Sildenafil Citrate is different from the original brand Viagra in its performance.

The regulatory authorities need generic drugs to have a bioequivalence effect, i.e. it needs to provide the same active ingredient into the blood at similar rates and concentrations.

Due to these demands, popular generic sildenafil citrate tablets like Cenforce, Fildena, and Kamagra have the same active ingredient, Sildenafil Citrate and have the same pharmacological effect as the brand drug.

The variations are normally based on the appearance of the tablet, packaging, or price as opposed to therapeutic efficacy. Generic Sildenafil Citrate is cheaper than Viagra because it does not carry the high research, development, and marketing costs associated with the original branded drug.

Factors in Lifestyle that determine the success of treatment

The health of the erection is not dependent on medicine. Every day habits influence blood vessels, nerve signal and hormonal balance. Healthy lifestyle habits, which are beneficial to heart health, usually increase the level of sexual performance too.

These include:

• Engaging in physical activities regularly.
• Regulating cholesterol and blood pressure.
• Avoiding tobacco use
• Restricting the use of alcohol.
• Controlling the stress and sleep patterns.

These assist in maintaining healthier blood vessels, and it enhances the body’s response to the erectile therapies.

Taking Sildenafil Citrate tablet to achieve a strong erection

Sildenafil Citrate is one of the most tested and best treatments for Erectile Dysfunction in many men. It offers a sure way of improving the quality of the erection of suitable candidates in that it increases the natural response of the body in terms of blood-flow during sexual stimulation.

Nevertheless, the knowledge of the mechanisms of action of the medication, the usage of various strengths, the rare possibility of the occurrence of the side effects as well as the impact of the lifestyle factors on the outcome assists in keeping the expectations concerning the treatment within the realistic scope.

When taking Sildenafil Citrate most responsibly and keeping general health in mind, the drug still retains a large portion of assisting men to feel confident and to gain control over their sexual wellbeing once again.
