What is the difference between Viagra and Cialis?

Viagra, known generically as sildenafil, is a popular brand name for tadalafil. It is available in both brand-name and generic versions. The main active component of Viagra is sildenafil, which works by inhibiting an enzyme called PDE5. This allows for more targeted and effective treatment. Cialis is another type of medication that works similarly, but it also contains tadalafil as its active ingredient. Cialis is available in generic form, but it is also available as an oral pill. Both Viagra and Cialis can be used to treat erectile dysfunction, which is the inability to achieve or maintain a hard erection suitable for sexual activity. It is important to note that these medications should only be taken under the guidance of a healthcare professional.

How does Viagra work?

Viagra, the brand name for sildenafil, works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). This enzyme is responsible for breaking down cyclic guanosine monophosphate (cGMP) into nitric oxide and cGMP, respectively. cGMP is a substance that promotes smooth muscle relaxation and blood flow to the penis. It also increases blood flow to the penis, facilitating an erection when sexually stimulated. When cGMP levels are low, nitric oxide is released and cGMP is converted to nitric oxide by phosphodiesterase type 5 (PDE5) in the body.

Cialis works by inhibiting PDE5, which is responsible for inhibiting the enzyme PDE5. By blocking PDE5, sildenafil enhances the effects of cGMP, which in turn enhances the ability of cGMP to relax the smooth muscles in the blood vessels of the penis. This is why it is so popular among men looking for enhanced sexual performance.

How much does Cialis cost?

The cost of Cialis varies from brand to brand. The average retail price for a 30-milligram tablet of tadalafil ranges from $4 to $7 per pill. The cost of the generic version of Cialis ranges from $4 to $12 per pill.

It is important to note that Cialis should only be used under the guidance of a healthcare professional, as it does not have FDA approval. It is important to consult with a healthcare professional to determine the most suitable form of medication for your needs. It is also important to be aware of the potential side effects of Cialis.

Interactions

A. Top Drug-Drug Interactions:

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.

Other Drug-Drug interactions:

  • Ketoconazole, itraconazole (used to manage fungal infection)
  • Protease inhibitors (used to manage HIV infection) Ex. ritonavir, lopinavir
  • Phenobarbital, phenytoin, carbamazepine (medicines used for fits)
  • Rifampicin, erythromycin, clarithromycin (medicines used for bacterial infections)
  • Other medicines used to improve blood flow to the penis (Ex. sildenafil)

B. Drug-Food Interactions:

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:

  1. Grapefruit and Grapefruit Juice: Grapefruit can increase the levels of tadalafil in your blood by interfering with its metabolism. This may amplify side effects, such as headaches, dizziness, or low blood pressure. Avoid consuming grapefruit or grapefruit juice while taking Cialis.
  2. Alcohol: Drinking alcohol with Cialis can enhance the blood pressure-lowering effects of the medication, leading to symptoms like dizziness, lightheadedness, or fainting. Limiting alcohol intake is recommended while using Cialis.
  3. High-Fat Meals: While Cialis can be taken with or without food, consuming it with a high-fat meal may delay its onset of action. Opt for lighter meals if rapid effectiveness is needed.
  4. Caffeine: Though not a direct interaction, combining Cialis with high caffeine intake might worsen side effects like headaches or increase heart rate in sensitive individuals.
