Glopir (Nifedipine)

Glopir is indicated for the management of several cardiovascular disorders where vasodilation is beneficial. It is commonly prescribed by healthcare professionals to address the following conditions:

• Hypertension (high blood pressure) requiring long‑term control
• Chronic stable angina pectoris to reduce chest pain episodes
• Vasospastic (Prinzmetal) angina associated with coronary artery spasm
• Off‑label use in certain cases of Raynaud's phenomenon under physician guidance
• Adjunct therapy in heart failure when other agents are insufficient

Side effects of Glopir vary in frequency and severity. Patients should be aware of both common and less frequent serious reactions.

Common

• Headache, often mild to moderate
• Flushing or warmth sensation, especially on the face
• Peripheral edema, typically swelling of the ankles
• Dizziness or light‑headedness, particularly after standing
• Nausea or abdominal discomfort

Serious

• Severe hypotension leading to fainting
• Rapid or irregular heartbeats (arrhythmias)
• Allergic reactions such as rash, itching, or swelling of the face and throat

Before starting Glopir, certain health considerations should be reviewed with a healthcare provider. Important precautions include:

• Existing low blood pressure or heart block conditions may increase risk of adverse effects
• Severe liver impairment can alter drug metabolism
• Pregnancy and breastfeeding status are unknown; discuss risks with a clinician
• Concomitant use of other antihypertensive agents may require dose adjustments
• History of heart failure or recent myocardial infarction should be evaluated
• Patients with gout should monitor uric acid levels, as nifedipine can affect them

Glopir can interact with various medications, influencing its efficacy or safety profile. Interactions are grouped as follows:

Avoid

• Strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin) which can raise nifedipine levels
• Grapefruit juice, which may increase systemic exposure
• Other potent vasodilators that could cause excessive hypotension

Use with caution

• Beta‑blockers or other antihypertensives, requiring close blood pressure monitoring
• Diuretics, especially thiazides, due to additive blood pressure lowering
• Digoxin, as changes in blood pressure may affect its therapeutic window
