METROPROLOL
Laboratory analysis of drugs to certify the presence of metoprolol and measure its concentration.
The level of uncertainty of the metoprolol content analysis depends on the declination selected (Standard <20%, Precise <10% or Regulatory <5%).
Follow the instructions to send your drug to our laboratory for analysis.

Metoprolol is a selective beta-blocker used primarily in the treatment of hypertension, angina pectoris and heart failure. It acts by reducing heart rate and blood pressure, thereby improving cardiovascular function.
Metroprolol is the active ingredient in Lopressor, Betaloc and Seloken.
Consuming drugs ordered from dubious or illegal websites can be hazardous to your health. It is essential to check that the online pharmacy is reputable and fully licensed.
If you have any doubts about the origin of the drug, you should carry out an analysis to certify the presence of the active ingredient and check that its dosage is in line with the indicated content.
Analysis
Metoprolol is analyzed by liquid chromatography coupled with UV-Visible spectrophotometric detection (HPLC-UV Visible).
Chemical name
- Chemical name: (RS)-1-(Isopropylamino)-3-(4-methoxyphenyl)propan-2-ol
- Gross formula: C15H25NO3
- CAS number: 37350-58-6
Therapeutic class
Metoprolol belongs to the class of β1-adrenergic selective beta-blockers, used for :
- Reduce blood pressure by lowering heart rate and cardiac output.
- Treat angina pectoris by reducing the heart's oxygen demand.
- Prevent cardiovascular complications, including after myocardial infarction.
- Manage certain cardiac rhythm disorders (tachycardias, atrial fibrillation).
- Treat chronic heart failure, by reducing the heart's workload.
Description of therapeutic effects
Metoprolol acts by selectively blocking beta-1 adrenergic receptors, which :
- Reduces the frequency and force of cardiac contractions, thereby lowering blood pressure.
- Reduces the heart's oxygen consumption, alleviating the symptoms of angina pectoris.
- Reduces stress on the cardiovascular system, preventing post-infarction complications.
- Stabilizes heart rhythm, reducing episodes of tachycardia.

Precautions and side effects
Precautions for use
- Do not stop treatment abruptly, as this may lead to hypertensive rebound or an angina attack.
- Use with caution in diabetic patients, as it may mask signs of hypoglycemia.
- Not recommended for patients with chronic obstructive pulmonary disease (COPD) or asthma, as it may aggravate respiratory symptoms.
- Monitoring in patients with severe heart failure, due to risk of initial worsening of symptoms.
- May interact with other cardiovascular drugs, requiring dose adjustment.
Possible side effects
- Common: fatigue, bradycardia (slowed heart rate), hypotension, dizziness.
- Occasional: sleep disorders, nightmares, digestive disorders (nausea, diarrhea).
- Rare but serious: aggravation of heart failure, bronchospasm, cardiac conduction disorders.
⚠️ Drug interactions: Metoprolol may interact with antihypertensives, tricyclic antidepressants, antiarrhythmics and some anti-diabetic drugs, requiring careful medical supervision.
