About the trial for Hypertension

Treatment Groups

This trial involves 2 different treatments. QUARTET LDQT is the primary treatment being studied. Participants will all receive the same treatment. There is no placebo group. The treatments being tested are in Phase 2 and have already been tested with other people.

Main TreatmentA portion of participants receive this new treatment to see if it outperforms the control.
Control TreatmentAnother portion of participants receive the standard treatment to act as a baseline.


This trial is for patients born any sex aged 18 and older. There are 6 eligibility criteria to participate in this trial as listed below.

Inclusion & Exclusion Checklist
Mark “yes” if the following statements are true for you:
People with high blood pressure who have not received treatment in the last 12 weeks and have blood pressure readings of 140-179 mmHg for systolic blood pressure or 90-109 mmHg for diastolic blood pressure, or have been taking medication to control their blood pressure but have readings of 130-159 mmHg for systolic blood pressure or 85-99 mmHg for diastolic blood pressure, are likely to benefit from taking medication to further lower their blood pressure. show original
1) People who have not received treatment before, 2) People who are not currently taking treatment, or 3) People who are currently taking a single blood pressure lowering drug at any dose. show original
Adults (≥18 years)

Who should consider clinical trials for hypertension?

Approximately one half of the hypertensives seen in primary care meet the trial entry criteria. The higher percentage of those that would qualify who were identified in this study reflects the fact that our study found many more patients with hypertension than would be detected in the average general practice population.

Anonymous Patient Answer

How many people get hypertension a year in the United States?

Hypertension was highly prevalent in this population sample. The prevalence of hypertension increases with age. The prevalence of hypertension is higher, although not yet statistically significant, among blacks and non-Hispanic whites than among Hispanics and Hispanics of Anglo/White race.

Anonymous Patient Answer

What is hypertension?

Hypertension is a common disease that, due to the fact that the disease is age-related, is a long-term problem that can last up to the age of over 70 years.\n

Anonymous Patient Answer

What are common treatments for hypertension?

A number of treatments options for hypertension are common to the general population. These include both medications (i.e. ACE inhibitor, calcium-channel blocker, diuretic, glucosamine, diuretic, nitrate, ACE inhibitor, calcium-channel blocker, or a beta-blocker), supplements, and medical foods tailored for hypertensive subjects (i.e. sodium restriction, low-sodium diet, or salt sensitivity products). Many treatments for hypertension have been proven by randomized controlled trials to be safe and confer significant benefit. Many of these treatments are relatively safe and cost-effective with no adverse effect on patient morbidity or mortality.

Anonymous Patient Answer

What causes hypertension?

The causes of hypertension are multiple and include excessive renin activity, vasoconstriction of the sympathetic nervous system, and aldosterone secretion. Most people with hypertension also have hypertension and/or obesity with or without comorbidities and in many cases, the cause is unknown.

Anonymous Patient Answer

Can hypertension be cured?

We can not state that a cure has been confirmed in the light of the data evaluated here. On the other hand, we suppose that it looks likely that the possibility of curing hypertension is possible. More prospective investigations should be performed with a better selection criterion of prospective patients with the help of more elaborate studies.

Anonymous Patient Answer

What are the signs of hypertension?

Hypertension is associated with several common signs, such as nasal congestion, dizziness and fatigue. These symptoms contribute to patient distress and may adversely affect quality of life.

Anonymous Patient Answer

How does quartet ldqt work?

Quartet LDqt may relieve pain, but for many people it hasn’t been shown to prevent or treat other symptoms of high blood pressure. There is a lack of information on side effects. There have been no long term studies done on quartet LDqt in the long term. There are currently few studies on quartet LDqt which only tested for short term pain. There are very few studies which explain how it was developed, and it is only on the market for 6 years, so the evidence base for it is very weak.

Anonymous Patient Answer

What is the primary cause of hypertension?

Hypertension is most common among people with diabetes mellitus, with obesity, and those with other medical conditions not usually seen with hypertension. I am not aware of any compelling evidence that establishes the superiority of one treatment over another for primary hypertension.

Anonymous Patient Answer

What are the common side effects of quartet ldqt?

The frequent adverse events of Quartet LDQ are gastrointestinal such as nausea, vomiting, itch, diarrhea and constipation, and some general symptoms such as insomnia, restlessness and dizziness. The most common side effect is neutropenia. It is advised that patients, particularly those who are taking antimalarial drugs, who complain of fever and myalgia be investigated for evidence of malignancy. It is reported that in some cases a prolonged QT interval can be observed when patients take one of the components of Quartet (for example, atorvastatin, clopidogrel, etc.). Therefore, patients should be informed of this possible side effect.

Anonymous Patient Answer

What are the latest developments in quartet ldqt for therapeutic use?

Recent advances from the NIH/NHLBI were highlighted which involved the development of novel therapeutic targets like the SGLT (sodium glucose cotransporter)1. The new therapeutic drug discovery platforms are a potentially valuable asset to current treatment of hypertension because of their flexibility in pharmacology, tolerability, ease of synthesis and their lack of interaction with other treatment options in antihypertensive therapy like SGLT2 (sodium glucose cotransporters) inhibitors and the other therapeutics like calcium channel antagonists.

Anonymous Patient Answer

Does quartet ldqt improve quality of life for those with hypertension?

This was a pilot study which demonstrated that quartet ldqt may be of benefit, at a low cost, in the management of patients with mild to moderate hypertension. The effect size, on HRQoL, was small. On this basis, further research, in the context of a larger clinical trial, is needed to establish a final conclusion.
