1.Nitrates (e.g., nitroglycerin, isosorbide dinitrate): Cialis and nitrates both lower blood pressure. Taking them together can cause a significant and potentially life-threatening drop in blood pressure (hypotension), leading to dizziness, fainting, or even heart attack or stroke. It is contraindicated to use Cialis with nitrates or recreational "poppers" (amyl nitrites).
2.Alpha-blockers (e.g., prazosin, terazosin, tamsulosin): Both Cialis and alpha-blockers relax blood vessels, which can lead to excessive blood pressure reduction when used together. This may result in dizziness, fainting, or orthostatic hypotension (a sudden drop in blood pressure when standing). If needed, your doctor may adjust the dosage or recommend spacing the medications.
3.Other antihypertensive drugs (e.g., atenolol, propranolol, enalapril, lisinopril): Cialis can enhance the blood-pressure-lowering effects of these medications. While this interaction is usually less severe than with nitrates or alpha-blockers, it can still cause dizziness or fainting in sensitive individuals. Close monitoring of blood pressure is recommended.
Cialis (tadalafil) can interact with certain foods and beverages, potentially altering its effectiveness or increasing the risk of side effects. Here are the key drug-food interactions to be aware of:

Helps reduce blood pressure
Current medical guidelines, as well as the pharmaceutical industry, do not recommend the use of PDE-5 inhibitors, such as sildenafil (Viagra®), vardenafil (Levitra®), or tadalafil (Cialis®), in the treatment of erectile dysfunction (ED). In clinical studies, the use of PDE-5 inhibitors has been reported to cause adverse effects in up to 70% of patients [
,
]. Although, the majority of these adverse effects are mild and transient, they may persist for several months or even years after discontinuation of therapy [
In fact, the frequency of these adverse effects is higher in patients taking nitrates (e.g., nitroglycerin) and recreational drugs, such as cocaine [
It is believed that the combination of nitrates with sildenafil, e.g., vardenafil, causes an additive effect and has no clinically important role in the treatment of ED [
Sildenafil is a phosphodiesterase-5 (PDE-5) inhibitor, which is a selective inhibitor of cyclic guanosine monophosphate (cGMP) breakdown, the degradation of which is known to be responsible for the enhancement of the vasodilatory effect of nitrates [
The vasodilatory effects of nitrates may be further enhanced by the inhibition of cGMP-specific phosphodiesterase (PDE-5) activity, which regulates the degradation of nitrates. In addition, PDE-5 is involved in the relaxation of smooth muscle cells in the corpus cavernosum of the penis, and it is believed that PDE-5 is expressed in the cavernosal smooth muscle in response to sexual stimulation and is associated with a greater smooth muscle relaxation when PDE-5 is expressed in the penile tissue [
In a clinical study, sildenafil significantly enhanced the time to onset of erections, and the maximum effects occurred within 1-2 hours [
The mechanism of PDE-5 inhibition by sildenafil is not known, but it may be a result of its inhibitory effect on PDE-5, which in turn may contribute to the enhancement of the local vascular endothelial function. Sildenafil may also have an effect on the cyclic guanosine monophosphate (cGMP)-cyclic nucleoside monophosphate-specific phosphodiesterase type-5 (PDE-5) enzyme activity, which is also inhibited by sildenafil in the presence of the cGMP activator cGMP [
In addition, sildenafil has also been shown to have a positive effect on the cyclic AMP-specific phosphodiesterase type-5 (PDE-5) enzyme, which is required for the degradation of cGMP in the corpus cavernosum [
The inhibition of PDE-5 by sildenafil also decreases the concentration of cyclic AMP, which is involved in the relaxation of smooth muscle cells and vascular endothelial function [
In the current study, we also observed an additive effect of sildenafil with PDE-5 inhibitor treatment on the effects of PDE-5 inhibitor on vascular endothelial function, and also observed the possible additive effect of sildenafil with sildenafil on the effects of PDE-5 inhibitor treatment on vascular endothelial function.
The clinical significance of the PDE-5 inhibitor in ED treatment is not fully understood. As a result, the therapeutic effect of PDE-5 inhibitors is considered to be different between patients and non-users [
PDE-5 is a type of phosphodiesterase, which is expressed by the corpus cavernosum and is also involved in the smooth muscle tissue relaxation by the endothelium. In patients with ED, PDE-5 inhibition leads to a decrease in the concentration of phosphodiesterase type 5 (PDE-5) in the corpus cavernosum, which may possibly contribute to the enhancement of blood flow to the penis during sexual stimulation [
The combination of nitrates with sildenafil, e.g.
Sildenafil Citrate
What is the best way to take sildenafil citrate?
Viagra is the brand name for sildenafil citrate, a phosphodiesterase type 5 inhibitor. It works by increasing blood flow to the penis, helping you get an erection.
In this article, we will explore the uses, benefits, side effects, and precautions of sildenafil citrate. We will also discuss the potential risks and benefits of taking the drug with other medications or supplements.
Sildenafil citrate is available in several forms and strengths such as 50mg, 100mg, 200mg, and 400mg. The most common form of sildenafil citrate is sildenafil citrate and is used to treat erectile dysfunction (ED) in men. Viagra is also sometimes used to treat pulmonary arterial hypertension (PAH) in men. The most common side effects of sildenafil citrate include headache, flushing, indigestion, and muscle aches. It is important to consult a healthcare professional for a thorough diagnosis and appropriate treatment.
What is sildenafil citrate used for?
Sildenafil citrate is used for the treatment of erectile dysfunction (ED) in men. It is also used to treat pulmonary arterial hypertension (PAH) in men. Viagra is available in both brand-name and generic forms. The medication is available in both tablet and liquid forms. Viagra is a phosphodiesterase type 5 inhibitor. This enzyme plays a key role in the production of a substance called cyclic guanosine monophosphate (cGMP), which is needed to pump blood from the penis to the spongy tissue around the base of the penis. The cGMP is released into the blood stream causing the spongy tissue to swell. The action of sildenafil citrate helps to maintain an erection.
Sildenafil citrate is available in several forms and strengths. It is typically taken orally with or without food, typically 2 or 3 times a day. The drug is generally taken three times daily, with or without food. It is important to follow your healthcare provider’s instructions regarding the dosage and frequency of use of the drug. It is also important to take sildenafil citrate at the same time each day, regardless of whether you take it with or without food.
Sildenafil citrate may also be taken in combination with other erectile dysfunction medications. Examples include Viagra, Levitra, and Cialis. You can also take it with or without food. It is important to consult with a healthcare provider to determine the best course of treatment for ED.
How does the drug work?
Sildenafil citrate works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which is responsible for breaking down cyclic guanosine monophosphate (cGMP). cGMP is responsible for relaxing the smooth muscles of the penis, which helps to increase blood flow to the penis and enhance erectile function. By blocking PDE5, sildenafil increases the levels of nitric oxide, which is responsible for relaxing the muscles in the penile arteries.
Sildenafil increases cGMP levels by enhancing the relaxation of the smooth muscle cells in the penile arteries. This is necessary for the penis to expand and maintain its ability to harden and firm.
Sildenafil citrate may also affect how well the blood vessels in the penis relax. This may be due to the vasodilation effects of sildenafil citrate that can help to relax blood vessels. The blood vessels in the penis may also be enlarged, which may result in increased blood flow to the penis. This may improve the ability to get and maintain an erection.
What are the precautions of sildenafil citrate?
Sildenafil citrate can be taken with certain medications, including nitrates. It is important to inform your healthcare provider about any medications you are taking to avoid any potential interactions with other medications you are taking. Some medications can be dangerous to the lungs and can cause severe breathing problems, including nitrates.
Sildenafil citrate is not a prescription medication.
Cialis has been shown to cause some mild side effects. Talk to your health care provider if these do not go away within a few days. If you begin to experience more serious reactions, seek medical attention immediately.
Common side effects reported from Cialis use include:
More severe side effects include:
If you experience any of these side effects, seek medical attention immediately. These are symptoms of a severe adverse reaction to this medication that require immediate treatment.
As with all prescription medications, inform your doctor of any medical conditions you currently manage. Tell them about any and all medications, prescription drugs, and supplements you are taking before starting treatment with Cialis. Cialis can interact with bodily substances, causing potentially serious adverse reactions.
Specifically, you should inform your health care provider of any alpha-blocker, antifungal, HIV protease inhibitor, or high blood pressure medication you are taking. Remember to mention any herbal products you use, especially St. John’s wort.
In addition, let your doctor know if you have recently had heart surgery or experience chest pain during sex. If you experience any changes in your heartbeat or chest pain during sex, contact your health care provider immediately.
