A Phase 3 interventional study of Etoricoxib + Betamethasone fixed dose and Etoricoxib fixed dose in Gout Arthritis and Gout Attack, sponsored by Laboratorios Silanes S.A. de C.V.. Recruiting at 1 site in Mexico. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-04-03.

Phase III longitudinal, multicenter, randomized, double-blind clinical trial. The aim of this study is to evaluate the efficacy and safety of the Fixed-Dose Combination of Etoricoxib/Betamethasone Versus Etoricoxib in Patients With Acute Gouty Arthritis
Researchers will compare the fixed-dose combination of Etoricoxib/Betamethasone versus Etoricoxib in acute gouty arthritis by comparing the level of pain in the affected joint during the 8 days of follow up. The adverse events related to the interventions will be registered during follow up.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Compare the degree of pain in the affected joint (using the Likert pain scale) on days 2, 5, and 8, according to their baseline measurement in each treatment group.
A Likert pain scale is a rating scale used to measure opinions, attitudes, or behaviors. It consists of a statement or a question, followed by a series of four answer statements. The pain should be assessed by the principal investigator or designated physician by asking the patient about the joint experiencing the MOST PAIN at the time of the baseline evaluation and during follow-up.
Time frame: 8 days
Number of participants with treatment-related adverse events through the patient's diary record.
To describe the frequency, intensity and causality of the adverse events presented during the clinical trial by treatment group. The adverse events will be registered by the patient in the diary record. Each adverse event will be followed up at the discretion of the researcher.
Time frame: 8 days
Compare the degree of inflammation (edema) in the affected joint (using the Likert edema scale) on days 2, 5, and 8 according to the baseline measurement for each treatment group.
A Likert edema scale is a rating scale used to measure opinions, attitudes, or behaviors. It consists of a statement or a question, followed by a series of three answer statements. The evaluation must be conducted by the Site Principal Investigator or designated physician on the most affected joint at baseline and during follow-up.
Time frame: 8 days

Time frame: 8 days
Describe the patient's subjective global assessment of the treatment received at the end of the 8-day follow-up period, by treatment group.
The Investigator must ask the patient the following question: "How would you rate the study medication you received for acute gouty arthritis?" at day 8 of follow-up. The assessment would be through a likert scale. The likert scales is a rating scale used to measure opinions, attitudes, or behaviors. It consists of a statement or a question, followed by a series of four answer statements.

Report the number of patients who require the use of rescue medication during the clinical trial in each treatment group
The rescue medication will be acetaminophen 500 mg: - The patient that considers the need for rescue medication must call the doctor, who will be in charge of applying the VAS scale by telephone. If the doctor considers it necessary, the taking of the rescue medication will be indicated.
Time frame: 8 days
To report the percentage of therapeutic adherence at day 8 of the intervention in each treatment group.
Therapeutic adherence will be defined by the principal researcher. Adherence to treatment will be defined as a consumption ≥ 80% of the doses that the patient should have ingested at the time of the corresponding evaluation.
Time frame: 8 days
