What is Vardenafil hydrochloride Powder?
Vardenafil hydrochloride powder,also called vardenafil HCL powder,is one of a enzyme phosphodiesterase type 5 (PDE5) inhibitors.This enzyme is responsible for the degradation of cyclic guanosine monophosphate (cGMP),a molecule that plays a crucial role in the erectile process.
During sexual arousal,nitric oxide is released in the erectile tissue of the penis (corpus cavernosum),which then stimulates the enzyme guanylate cyclase.This enzyme increases levels of cGMP,which in turn relaxes the smooth muscle cells in the corpus cavernosum.The relaxation of these muscles allows more blood to flow into the penis,leading to an erection.
By inhibiting PDE5,AASraw vardenafil hydrochloride powder prevents the breakdown of cGMP,thus maintaining higher levels of this molecule and prolonging its effects.This results in sustained muscle relaxation and blood flow,thereby aiding in the maintenance of an erection during sexual activity.
How does Vardenafil hydrochloride Powder work?
Vardenafil hydrochloride powder works as a selective inhibitor of an enzyme called phosphodiesterase type 5 (PDE5).Here’s a step-by-step guide to how it works:
①Sexual stimulation triggers the release of nitric oxide in the corpus cavernosum,a region of the penis.
②This nitric oxide triggers an enzyme called guanylate cyclase to convert guanosine triphosphate (GTP) into cyclic guanosine monophosphate (cGMP).
③The cGMP causes the smooth muscles in the corpus cavernosum to relax,which allows the blood vessels to dilate.
④The dilation of the blood vessels increases blood flow into the penis,leading to an erection.
⑤Normally,the enzyme PDE5 breaks down cGMP,ending the erection.Vardenafil hydrochloride works by inhibiting the action of PDE5,thus allowing the cGMP to remain longer and prolong the erection.
⑥Ultimately,vardenafil hydrochloride enhances and sustains the biological process that leads to an erection in response to sexual stimulation.
It’s important to understand that vardenafil hydrochloride does not cause an erection directly.Instead,it enhances the body’s natural response to sexual stimulation.Also,it’s important to buy vardenafil hydrochloride powder from reliable supplier like AASraw,which have supplied pure verdenafil hcl powder for many years.
Vardenafil VS.Avanafil VS.Tadalafil VS.Sildenafil
The four most common PDE5 inhibitors on the market are sildenafil,tadalafil,vardenafil,and avanafil.These four medications are all PDE5 inhibitors and are the first line of treatment for ED.However,the chemical molecular structures of these four medications differ,resulting in various chemical and physical actions.As a result,their absorption,distribution,metabolism,and excretion in the body varies,as do their curative effects.
| Coscóir PDE5 | Tosú Gníomh | Tmax (h) | Cmax (ng/ml) | T1/2 (h) | Duration (h) | Main Adverse Reactions |
| sildenafil | 30 nóiméad-1 uair an chloig | 0.8-1 | 560 | 2.6-3.7 | 4 | Headache,facial flushing,indigestion,nasal congestion,dizziness,abnormal vision |
| Vardenafil | 15 min | 0.9 | 200 | 3.9 | 8 | Headache,facial flushing,indigestion,nasal congestion,dizziness,abnormal vision |
| Tadalafil | 1h | 2 | 378 | 17.5 | 36 | Headache,facial flushing,indigestion,nasal congestion,dizziness,no visual abnormalities |
| Avanafil | 10-15 min | / | > 1000 | 3-5 | 6-8 | Headache,facial flushing,indigestion,nasal congestion,dizziness (less frequent compared to others) |

Cmax = maximum plasma concentration
T1/2 = half-life
This table summarizes the pharmacokinetic characteristics of the four PDE5 inhibitors discussed.It’s always important for healthcare providers to consider these differences when prescribing these medications,and patients should always use these medications under the supervision of a doctor.Moreover,buying vardenafil hcl powder from a trusted supplier such as AASraw assures you receive a product of excellent quality and purity.AASraw ,as a professional vardenafil hcl powder supplier,can supply vardenafil hydrochloride powder with high quality all over the world.
How to choose PDE5 inhibitors?
Choosing the right PDE5 inhibitor can depend on a variety of factors,including the patient’s overall health,the presence of other conditions,their lifestyle,and their individual response to medication.Here is a general guide to choosing a PDE5 inhibitor for reference,but remember to always consult with a healthcare provider to make the best choice for individual needs.
| Patient Condition | Recommended PDE5 Inhibitor | Cúis |
| Desire for fast onset time | Avanafil | Fastest onset among the PDE5 inhibitors |
| Middle-aged and elderly with ED and chronic diseases (hypertension,hyperlipidemia) | sildenafil | Average pharmacokinetic parameters,less stimulation to the body |
| Middle-aged and elderly with ED and vascular endothelial dysfunction (e.g.diabetes) | Tadalafil | Long duration of action,can improve vascular endothelial function and urinary tract symptoms over time |
| Middle-aged and elderly with ED,no vascular diseases | Vardenafil | Mild effect,quick onset,low bioavailability,few adverse reactions |
| Middle-aged and elderly with ED,vascular endothelial dysfunction,sildenafil ineffective | Avanafil | High blood concentration,strong effect |
| Young and middle-aged with ED,no obvious organic etiology | sildenafil | Effective for ED caused by psychological factors |
| Abnormal visual function and ED | Tadalafil | No visual abnormalities among adverse reactions |
| Postprandial medication preference | Avanafil,Vardenafil | Absorption rate not easily affected by food |
Notes:This information about PDE5 inhibitors is provided for general informational purposes only and does not constitute medical advice.The choice of a PDE5 inhibitor should always be made in consultation with a healthcare provider who can take into account the individual’s overall health,other medications being taken,and the specific nature and severity of the erectile dysfunction.While these medications can be effective in treating erectile dysfunction,they also have potential side effects and risks,and they are not suitable for everyone.Certain health conditions and other medications may interact with PDE5 inhibitors,leading to potentially serious adverse effects.Always seek the advice of a healthcare provider for any questions you may have regarding a medical condition.
Dosage and administration of Vardenafil hydrochloride Powder for reference
The dosage of vardenafil HCL powder may vary depending on the individual’s health,response to treatment,and other medications they may be taking.Here are general recommendations,but it is essential to follow your healthcare provider’s specific instructions.
①Caighdeán dose for erectile dysfunction
The recommended starting dose of vardenafil is 10 mg,taken orally approximately 60 minutes before sexual activity.The dose may be increased to a maximum of 20 mg or decreased to 5 mg,based on individual efficacy and tolerability.The maximum recommended dosing frequency is once per day.
②Othair le moderate hepatic impairment
For patients with moderate hepatic impairment (Child-Pugh B),a starting dose of 5 mg of vardenafil is recommended.The maximum dose in patients with moderate hepatic impairment should not exceed 10 mg.
③Othair le sriamh realadh impairment
For patients with severe (CLcr <30 mL/min) renal impairment,a starting dose of 5 mg of vardenafil is recommended.
④Patients on stábla alpha-bloosely tleiripe
The recommended starting dose of vardenafil for patients receiving stable alpha-blocker therapy is 5 mg.
⑤Othair le concomitant use of CYP3A4 inhibitors
For patients taking potent CYP3A4 inhibitors (such as ketoconazole,itraconazole,ritonavir,indinavir,saquinavir,and atazanavir),an initial dose of 5 mg vardenafil should not be exceeded.
