Is online cialis legal

1. Introduction

Cialis is a well-known prescription medication used to treat erectile dysfunction (ED) and is also commonly prescribed for pulmonary arterial hypertension (PAH). In Singapore, approximately 80% of men with ED also have PAH.

Cialis is an oral prescription medication that is available in various dosages. It is also available as a generic drug and can be purchased without a prescription.

In the current study, we sought to explore the use of Cialis in Singapore and explore its potential risks and benefits, including its suitability as a treatment option for patients with PAH. Our primary objective was to provide a preliminary insight into the availability of Cialis and explore its potential benefits for patients with PAH.

2. Methods

2.1. Study design, setting and participants

This was a descriptive cross-over study, whereby the primary objective of this study was to explore the availability of Cialis and explore potential benefits from the treatment of erectile dysfunction (ED) and pulmonary arterial hypertension (PAH).

2.2. Ethical considerations

This study was approved by the Institutional Review Board (IRB) of the National University of Singapore (IRB No. NU14/HSG09/1/038).

2.3. Study setting and participants

The study was conducted at the NU14/HSG09/1/038 clinical research center in Singapore. The center operates a comprehensive healthcare system that includes a network of healthcare providers, pharmacies, and medical practices. It is accredited by ACCESS Good Practice Practice (GPS) accreditations, which ensure that healthcare professionals are involved in the diagnosis, treatment and monitoring of ED and PAH.

2.4.

This study was only performed at a research institution. No ethical approval was obtained for this study. The study received ethics approval from the Institutional Review Board (IRB) of the National University of Singapore (IRB No.

2.5. Data collection

This study utilized a retrospective chart review of patients referred to the NU14/HSG09/1/038 research clinic at the NU14/HSG09/1/038 clinical research center in Singapore. Patients were referred to the study centers from the National Hospital General Hospital (NHHG) and the General Hospital of Chiang Mai, Thailand, using a list of potential medications for ED and pulmonary arterial hypertension.

This study sought to explore the availability of Cialis and explore its potential benefits for patients with PAH. Patients with PAH were defined as those who were able to achieve and maintain a satisfactory erection sufficient for sexual activity. In this study, the availability of Cialis was assessed using the International Index of Erection (IIEF) score.

The IIEF is a short questionnaire that is used to measure the ability to perform sexually appropriate sexual intercourse. The score is determined by the researcher based on the frequency and severity of the symptoms and the ability to perform an erection for intercourse.

The IIEF score is a questionnaire that measures the ability to perform an erection for intercourse. It includes the frequency of ED symptoms, frequency and severity of the ED symptoms, and the ability to perform an erection for intercourse.

The IIEF questionnaire is a validated tool that has been used to assess the frequency and severity of erectile dysfunction in men with PAH.

The IIEF questionnaire has been developed specifically for the study of erectile dysfunction in men. The questionnaire has been validated by various authors, including our own and colleagues.

3. Results

Of the 160 patients referred for the study, 90 were eligible for inclusion. The mean age of patients was 54.0 years (range 31 to 74). The mean age of participants was 67.8 (range 25 to 90). The mean IIEF score was 13.7 (range 3 to 30).

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.

Top Drug-Drug Interactions

: As one of the most widely used blood pressure medications, nitrates can reduce blood flow to the penis, a essential component of thrived sexual activity. This may lead to excessive blood pressure reduction, posing a risk to sexual health.

: Both Cialis and alpha-blockers reduce blood pressure by blocking cholesterol levels, which are essential for blood vessels to function well.

Other antihypertensive drugs (e.g., atenolol, propranolol, terazosin): Nitrates can worsen symptoms of colds and heart conditions, necessitating carefulness during treatment. Seek medical attention if you experience severe dizziness, fainting, or heart attack or stroke in response to any of these conditions.

  • Stomach pain
  • Muscle aches
  • Back pain

Cialis can be taken with or without food. However, if you take Cialis with a fatty meal, it may take a little longer to kick in. You should avoid the fatty meal, which can reduce its effectiveness, as it can delay the start of action.

If you take Cialis with a heavy or high-fat meal, you may experience an onset of headaches within a few hours of taking the medication. This is due to Cialis’s longer half-life, which means it remains active in your bloodstream for longer.

Cialis can also interact with nitrates found in some prescription drugs, affecting how well they work. This can result in dizziness, especially when rising from a sitting or lying position.

Cialis can also interact with other medications, including alpha-blockers that are used to treat benign prostatic hyperplasia, and nitrates used to treat angina.
