Modern pharmaceutical market is abundant of various ED treatment drugs. Why are they so popular and what are the reasons of their number growth? The answer is quite evident. The modern world has faced the growing problem of men’s sexual dysfunctions. The factors influencing the situation involve bad habits, sedentary lifestyle, stresses and bad environment. Thus, ED treatment drugs’ popularity forces pharmaceutical producers to offer new products in order to meet the requirements of the market. This article is dedicated to Kamagra that is already well – known at the market and Stendra, a relatively new medication that appeared several years ago.
What is common about Stendra and Kamagra?
The major common feature of Stendra and Kamagra is their reference to the group of PDE5 inhibitors which main indication is a treatment of the erectile dysfunction. Having appeared nearly 20 years ago these medications provided a lot of men all over the world with the chance to improve their sexual life without considerable interventions into their body (we mean various kinds of surgical intervention).
PDE5 inhibitors are characterized by high efficiency, relatively small quantity of side effects (though pharmaceutical companies try to warn even about the rarest ones) and good acceptability.
Avanafil vs. Sildenafil
The medications have different active ingredients: Sildenafil – for Kamagra and Avanafil – for Stendra. Sildenafil is considered to be a pioneer of PDE5 inhibitors as it was the first substance that was tested and recognized to have ED treatment properties in 1998. Sildenafil is used in Viagra, the legend of the pharmaceutical industry. By the way, it is the reason why Kamagra is often called a generic (or affordable) Viagra.
Avanafil refers to the group of new-generation medications; it was invented in 2011 and approved by FDA in 2012. Avanafil is known for its fast absorption and response. The large quantity of clients notes the ability to start sexual intercourse in 15 minutes after the intake of Stendra. The therapeutic action of Stendra usually lasts 6 hours.
At the same time Kamagra’s action starts in 40-60 minutes after the intake of the pill and lasts 4 hours.
How to take and What to avoid?
PDE5 inhibitors are taken once a day before the planned sexual intercourse. In case of Stendra it takes 15 – 30 minutes for the medication to start acting. If the patient takes Kamagra he may need 40 to 60 minutes before the coitus as Kamagra requires more time to start.
While choosing between these two drugs one should remember that in case of Sildenafil (Kamagra) the starting dosage should be 50 mg or even 25 mg (especially when it concerns elderly patients). The largest recommended dosage of Sildenafil is 100 mg.
The starting dose of Avanafil is 100 mg (patients over 65 should start with 50 mg). If everything is OK for the patient’s health, he can try 200 mg of Avanafil.

Canadian Pharmacy summary of Kamagra uses, effects, cautions and tips
Kamagra helps men affected by ED to achieve and maintain an erection. Sildenafil is used to treat erectile dysfunction and to reduce erectile dysfunction and increase erectile function. The active ingredient has no anti-stress effect, that is, it does not automatically lead to an erection after an intake.
The active substance sildenafil is added to the group of phosphodiesterase inhibitors. For the production of an erection, nitrogen (NO) activates the release of the messenger cGMP (cyclic guanine monophosphate), which causes the smooth muscle to relax in the penis. Thus the blood can flow into the corpus cavernosum.
The enzyme PDE5, on the other hand, is formed when the sexual climax is reached and the erection should be relieved. In the case of impotence, this enzyme is released too early so that it either leads to an early decay of the erection or does not result in an erection. The active substance sildenafil contained in Kamagra is involved in this process and inhibits the enzyme PDE5. Thus, the release of the enzyme is delayed and the messenger cGMP remains active for longer.
Kamagra is taken 30 to 60 minutes before sexual intercourse. Do not take Kamagra if you are pregnant or breast-feeding. The film tablets are swallowed whole with a little water. The effect of Kamagra is 4 to 5 hours, during which time the sexual act can be performed several times.
Kamagra film tablets should be taken 30 minutes before the scheduled sexual act. The recommended initial dose is 50 mg unless the doctor has prescribed a different dosage. Depending on the efficacy or tolerability, the dose can be reduced to 25 mg or increased to 100 mg. The recommended maximum dose is 100 mg per day. Do not take more than once a day. In men over 65 years of age no dose adjustment is required. The drug is not indicated for use in children and adolescents under 18 years of age.
The enjoyment of alcohol can degrade the ability to achieve an erection. To get the most benefit from Kamagra, do not drink large amounts of alcohol before taking the medication. If Kamagra is taken with greasy food, the effect of the drug may be delayed compared to sober intake.
If Kamagra is taken, this should not be done with grapefruit juice. The substance furanocoumarins, which is contained in grapefruit, blocks the enzyme CYP3A4, which causes the degradation of substances in the intestine. As a result, the concentration of sildenafil in the blood increases and the risk of side effects are increased.
Most side effects known to occur with Kamagra are usually mild to moderate and of short duration. If chest pain is experienced during or after sexual intercourse, it is recommended that you take a half-biting posture and relax. No nitrates should be used and the doctor should be immediately and immediately notified.
All medicines, including Kamagra, can cause an allergic reaction. A doctor should be immediately informed if the following symptoms are noticed after taking Kamagra: swelling of the eyelid, face, lips, or throat, difficulty breathing or dizziness, sudden startling whistling.
The following symptoms should also be immediately consulted by a physician: if a sudden deterioration or loss of vision is observed, or an excessively long-lasting, sometimes even painful, erection of more than four hours is present. Taking Kamagra can affect your vision and cause dizziness. Individual attention should be paid to how the personal response to the drug is presented before a vehicle is steered or machines operated.
The active substance sildenafil and some drugs may interfere with each other and thus cause interactions. This applies in particular to medicines used for the treatment of heart disease.
As a general rule, Kamagra should not be used with medicines containing the following active ingredients:
- (For the treatment of angina pectoris) Isosorbide mononitrate (used to treat angina pectoris) Isosorbide dinitrate (used to treat angina pectoris / coronary sclerosis)
- Sildenafil should also not be used if concurrent medications for pulmonary arterial hypertension, enlarged prostate, HIV or hepatitis C are taken. In addition, nitrate-containing drugs (for the treatment of heart diseases) can cause an acute blood pressure drop.
In case of hypersensitivity to the active substance or to any of the other ingredients in the tablet, Kamagra should not be taken. Since sildenafil enhances the blood pressure lowering effect of nitrates, co-administration with nitric oxide donors and any nitrates is contraindicated.
People with severe cardiovascular disease such as unstable angina or severe heart failure, cannot take Kamagra. Your physician or any other prescriber will inform you about other counter-indications in which sildenafil is contraindicated. Alternatively, these can be found in the detailed package leaflet. The medicine should not be taken under any circumstances if the doctor does not specifically allow it.
Dosage recommendations for adult men also apply to men with mild to moderate renal insufficiency. In men with hepatic impairment, as a rule, a dose of 25 mg can be considered. Depending on the efficacy and tolerability of Kamagra, the dose may be increased step by step to 50 mg to 100 mg if necessary.
If you experience any side effects while you are taking Kamagra, tell your doctor or pharmacist as soon as possible. If a side effect suddenly develops or develops strongly, the medication should not be taken further without a doctor’s prescription until re-diagnosis.

My Canadian Pharmacy Rx Stendra sum-up
In the treatment of erectile dysfunction, a large number of affected patients use prescription medications such as Stendra and regain a stable sexual life without any performance pressure. The active ingredient avanafil contributes to the expansion of the blood vessels and supports the penis erection. The potency is already 15 to 30 minutes after intake and up to 6 hours. Therefore, Stendra supports a ‘spontaneous’ and multiple sexual intercourses.
The effect of Stendra is based on the PDE5 inhibitor avanafil. PDE5 stands for the enzyme phosphodiesterase5. The PDE5 occurs, among other things, in the penis of the penis and provides for the degradation of cyclic guanosine monophosphate (cGMP).
