Metoprolol succ ER 25 mg is a specific dosage form of metoprolol succinate, a beta-blocker medication used to treat various cardiovascular conditions. It is a once-daily extended-release formulation designed to provide a consistent level of the drug in the body.
What conditions does metoprolol succinate treat?
Metoprolol succinate is prescribed for hypertension (high blood pressure), angina pectoris (chest pain caused by reduced blood flow to the heart), and to improve survival after a heart attack [1]. The 25 mg dosage is typically one of the lower starting strengths available for these indications.
How does extended-release metoprolol work?
The "succ ER" in metoprolol succ ER stands for succinate extended-release. This formulation releases the metoprolol succinate gradually over a 24-hour period. This sustained release helps maintain stable blood levels of the medication, which can reduce the frequency of dosing and potentially minimize side effects associated with rapid drug absorption [2].
When does patent protection for metoprolol succinate expire?
Patent exclusivity for metoprolol succinate has largely expired, allowing for generic versions to be available. For example, U.S. patent 5,407,940, which relates to metoprolol succinate formulations, expired in 2013 [3]. This means that various companies can now manufacture and market generic metoprolol succinate products.
Who manufactures generic metoprolol succinate 25 mg?
Numerous pharmaceutical companies produce generic metoprolol succinate 25 mg. These include major generic drug manufacturers. Consumers can find different brands of generic metoprolol succinate 25 mg at pharmacies.
What are the potential side effects of metoprolol succinate?
Common side effects of metoprolol succinate can include fatigue, dizziness, slow heart rate, and cold hands and feet. Less common but more serious side effects can occur, and patients should consult with their healthcare provider if they experience any concerning symptoms [1].
How does metoprolol succinate compare to immediate-release metoprolol tartrate?
Metoprolol succinate is an extended-release formulation, while metoprolol tartrate is typically an immediate-release formulation. Extended-release metoprolol succinate is taken once daily, providing a consistent therapeutic effect. Immediate-release metoprolol tartrate often requires dosing multiple times a day and can lead to more fluctuations in drug levels [2].
Can I switch from metoprolol tartrate to metoprolol succinate?
Switching between metoprolol tartrate and metoprolol succinate should only be done under the guidance of a healthcare professional. They will determine the appropriate dosage and timing for the switch, considering the patient's specific medical condition and response to treatment [1].
What if I miss a dose of metoprolol succ ER 25 mg?
If a dose of metoprolol succ ER 25 mg is missed, patients are generally advised to take it as soon as they remember, unless it is close to the time for the next scheduled dose. In that case, they should skip the missed dose and continue with their regular dosing schedule. Doubling up on doses is typically not recommended [1].
