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.

Added/Advanced

• High-Fat Meals, mealtimes such as St. John's wort, whodeo, kore, and caffeine.
• Stable Schedule: Keep in a dry location and where you're unlikely to feel discomfort.

C. Drug-Medical Interactions:

Cialis (tadalafil) can interact with certain medical conditions and medications, including alpha-blockers and diuretics, potentially altering its effectiveness or increasing the risk of side effects. You should not use Cialis with conditions if you take nitrates or nitric oxide donors while using these medications. While this interaction is often less severe than with nitrates or alpha-blockers, it can still cause side effects and complications:

• Chest pain or tightness.
• Pulmonary hypertension.
• Sharply heartbeat.
• Rapid weight gain.
• Loss of vision.

This story was updated at the beginning of the pandemic when many of these patients had been treated by their physicians.

A group of Thai doctors are developing a new drug to help treat pulmonary hypertension in patients who are at high risk of having a heart attack, according to the United Kingdom-based Institute of Medicine.

“We are very excited to explore our options for treating pulmonary hypertension, and we are very concerned that patients at high risk of being diagnosed with heart disease, may not have the proper treatment options available for them,” Dr. Pappong said in a statement.

A pulmonary hypertension diagnosis in patients who are at high risk for having a heart attack in the past is generally made on the basis of the clinical history, but the team will need to conduct a trial in order to determine if the patient is at high risk for having a heart attack. The doctor will then be able to determine whether the patient is at risk for a heart attack and if the patient’s family members or friends, or others, are at risk.

The trial is part of a larger, Phase 3 study to evaluate the safety and efficacy of an alternative treatment option for patients at high risk of having a heart attack in the future.

The study will test a single-dose of sildenafil (the active ingredient in Viagra), a drug used to treat pulmonary hypertension and is being funded by Pfizer, which is the maker of the brand name Cialis.

In this case, the drug was tested in a trial on people who were at high risk for being diagnosed with pulmonary hypertension.

The drug was approved by the Food and Drug Administration in November 2014. The Food and Drug Administration recently approved sildenafil for pulmonary hypertension, which is also known as angina. This drug is not approved for use in adults, but is approved to treat pulmonary hypertension in adults who are at high risk for having a heart attack. The drug’s patent has expired, but its patent for sildenafil is still valid.

Sildenafil, the active ingredient in Viagra, is the first drug approved to treat pulmonary hypertension in adults, and it is not yet available in the United States.

Pfizer, which is the maker of the original Cialis brand, has said in a statement that the approval for Viagra is “an important milestone in the development of the drug.”

According to a study published in the January issue of the New England Journal of Medicine, Viagra can cause serious side effects in about one-third of patients. Some people who take the drug for pulmonary hypertension or other conditions can develop a heart attack or stroke, and those who do not have the condition can die. The study also found that some people who took sildenafil for pulmonary hypertension had a higher risk of having a stroke than those who had not.

While some patients with pulmonary hypertension and those who take Viagra for other conditions can have heart attacks or strokes, others are not at high risk for having a heart attack, said Dr. Pappong.

Pfizer said that while Viagra is not currently approved for use in patients with the condition, it is still an important drug for people who are at high risk for being diagnosed with pulmonary hypertension. It also said that the drugs approved to treat the condition are not intended to treat pulmonary hypertension.

The study is not yet expected to take place in the United States, but Pfizer, which is an American company, said it was not immediately making a decision on whether to make a decision about the drug’s approval.

Pfizer

Pfizer, a pharmaceutical company, has launched an expanded clinical trial in the US to test whether sildenafil, the active ingredient in Viagra, can treat pulmonary hypertension.

The company is evaluating the safety and efficacy of the drug as it looks to determine whether or not patients at high risk of having a heart attack or stroke could be diagnosed with a potentially life-threatening condition.

The drug is expected to be approved in the U. S. for people who are at high risk for having a heart attack in the future. The FDA also is evaluating the safety and efficacy of the drug as it looks to determine whether or not patients at high risk of having a heart attack could be diagnosed with a potentially life-threatening condition.

Added/Neweriral Therapy

C.

Both Cialis and tadalafil can interact with certain foods and beverages, possibly altering the effectiveness or increasing the risk of side effects. Here are the key drug-food interactions:

1. Grapefruit: Grapefruit can increase the levels of tadalafil by inhibiting the enzyme cathepsin 1. This enzyme is involved in how tadalafil is broken down in the penis, causing blood to flow through the penis at will. By blocking this process, cathepsin 1 can be used to treat erectile dysfunction.
2. : Though not a direct interaction, combining Cialis with grapefruit might exacerbate side effects like headaches or increase side effects giving this medication.
3. : While taking Cialis may delay its onset of action, itsordia can still be needed to make sure you find an enjoyable, high-fat meal before taking this medication.
