Active Ingredients of Cobra 120mg

Cobra 120mg Indications

Cobra 120mg is a generic drug that contains the active ingredient “Sildenafil” and has an effect to improve erectile dysfunction.

Cobra 120mg is an ED treatment manufactured by Indian pharmaceutical company Signature Pharmaceuticals and is a generic version of Viagra. All Signature Pharmaceuticals products are manufactured in facilities that comply with GMP (Good Manufacturing Practices) and can be said to be a reliable pharmaceutical manufacturer for quality and safety.

In addition, although it contains a high dose of 120 mg of active ingredients, the price is about 1/5 of Viagra, and one of the advantages is that the economic burden of ED treatment can be reduced.

Features of the Cobra 120mg

The best feature of Cobra 120mg is that it is a generic drug containing the same ingredients as Viagra, the world’s first ED treatment drug. The active ingredient, sildenafil, is one of the three major active ingredients in ED treatment drugs along with vardenafil (Levitra) and tadalafil (Cialis), but it has two advantages when compared to the other two ingredients.

The first is its high bioavailability. Bioavailability refers to the percentage of active ingredients that are actually absorbed by the body. Sildenafil has a bioavailability of 41%, which is nearly three times higher than vardenafil’s 14.5%.

The second advantage of sildenafil is its sharpness of effect.

Sildenafil peaks in blood about 1 hour after administration, and its effect lasts for about 5 hours. This is relatively short compared to tadalafil, which has a particularly long effect time, but even if minor side effects appear, they will subside in a relatively short time as the active ingredient is metabolized.

Cobra 120mg, which contains sildenafil, which has these benefits, is recommended for those who want to improve ED more efficiently with proven ingredients, and for those who are worried that the effect of the drug will not remain after the next day.

It is also recommended for those who have not obtained sufficient effects from domestic prescriptions.

Cobra 120mg is a therapeutic drug that was originally formulated for Westerners with large physiques. Therefore, it can be said that it is suitable for those who have not been able to obtain a sufficient ED improvement effect with a prescription of 50mg, which is the upper limit of the dosage of sildenafil in USA, such as relatively large people and those who tend to be obese.

However, if you have only ever taken 50mg, it is recommended that you start with 50-60mg in divided doses instead of taking one tablet (120mg of sildenafil) from the beginning. If symptoms do not improve, the dose should be gradually increased.

An overwhelmingly high dose and extremely cost-effective ED treatment drug

Cobra 120mg contains a high dose of 120mg Sildenafil. The upper limit of sildenafil prescribed in USA is 50mg, so the dose is more than double that. For the average USA man, it is recommended to divide the dose with a pill cutter and start taking it from a low dose.

In addition, the price is about one-fifth of Viagra’s 100mg tablets, making it an affordable price for those trying ED treatment for the first time.

If you take it in divided doses, the cost per dose can be further reduced, and it is a generic drug recommended for those who want to proceed with ED treatment while minimizing the cost burden as much as possible.

Effect of Cobra 120mg


  • ED improvement

Cobra 120mg promotes blood flow to the corpus cavernosum of the penis due to the vasodilating action of the active ingredient sildenafil, causing a hard and powerful erection. This erection requires sexual stimulation, so taking Cobra 120mg does not mean that you will get an erection involuntarily.

The ED improvement effect of Cobra 120mg begins to appear 30 minutes to 1 hour after taking and lasts for about 5 hours. It is important to adjust the timing of administration based on the fact that the effect reaches its peak 1 hour after administration and that administration on an empty stomach is effective.

How to take Cobra 120mg

1 Dose
0.4 to 1 tablet (50 to 120mg as sildenafil)
When to take
1 hour before intercourse
Number of doses per day
Interval between doses

Cobra 120mg should be taken 0.4 to 1 tablet once daily with plenty of water or lukewarm water.

Cobra 120mg should be taken 0.4 to 1 tablet once daily with plenty of water or lukewarm water.

The active ingredient, sildenafil, is easily affected by dietary lipids, so it is recommended to take it on an empty stomach. If you take it after a meal, wait about 2 hours before taking it.

Precautions when taking

Cobra 120mg contains 120mg of the active ingredient, sildenafil. Given that the upper dose limit for sildenafil is 100mg overseas and the upper dose limit approved in USA is 50mg, this is a very high dose. Therefore, when taking Cobra 120mg for the first time, it is recommended to divide it with a pill cutter and start with a low dose.

It is said that there is no medical correlation with alcohol, but the vasodilating action of the active ingredient may make it easier for alcohol to circulate than usual. Avoid drinking large amounts of alcohol while taking Cobra 120mg.

In addition, depending on the constitution and dosage, symptoms such as temporary dizziness may appear. Avoid driving, operating machinery, and dangerous work while taking Cobra 120mg.

About the Active Ingredients of Cobra 120mg

Sildenafil inhibits the action of PDE and promotes vasodilation

The active ingredient in Cobra 120mg, sildenafil, is a PDE (phosphodiesterase) inhibitor and is the same ingredient as Viagra.

Normally, when the smooth muscle of the corpus cavernosum of the penis relaxes, the blood vessels dilate and the blood rushes into them, causing an erection. At this time, cGMP (cyclic guanosine monophosphate) is a signaling substance that is involved in the relaxation of corpus cavernosum smooth muscle, and PDE is a hydrolytic enzyme that decomposes it.

Sildenafil prevents the breakdown of cGMP by inhibiting the enzymatic activity of this PDE, leading to normal erections.

Cobra 120mg Side Effects

Major side effects

  • Headache, bloodshot eyes, hot flashes, palpitations, nasal congestion, etc.

Due to the vasodilatory action of the active ingredient, sildenafil, symptoms such as hot flashes and hyperemia similar to drinking alcohol may appear. In most cases, it will subside with the passage of time, but if the symptoms worsen or do not subside for a long time, please consult your doctor or pharmacist.

Rare side effects

  • Visual abnormalities (photophobia), priapism (priapism)

Although very rare, you may experience a visual symptom called photophobia, which is an excessive feeling of light, or priapism, which is a painful erection lasting several hours. If you feel any abnormality, stop taking Cobra 120mg and consult a doctor immediately.
