Golasan (Losartan Potassium)

Golasan is prescribed for several cardiovascular and renal indications where inhibition of the renin‑angiotensin system is beneficial.

• Management of hypertension (high blood pressure).
• Treatment of heart failure to improve symptoms and reduce hospitalizations.
• Slowing progression of diabetic nephropathy.
• Post‑myocardial infarction therapy for left ventricular dysfunction.
• Reducing risk of stroke in patients with established vascular disease.

Side effects of Golasan vary in frequency and severity. Patients should be aware of both common and potentially serious reactions.

Common

• Dizziness or light‑headedness, especially after the first dose.
• Headache.
• Fatigue or tiredness.
• Nasal congestion or sinus discomfort.
• Upper respiratory tract infection symptoms.
• Mild gastrointestinal upset such as nausea.

Serious

• Severe hypotension (marked drop in blood pressure).
• Hyperkalemia (elevated blood potassium levels).
• Acute kidney injury or worsening renal function.
• Angioedema (swelling of face, lips, tongue, or throat).

Before starting Golasan, certain health considerations should be reviewed with a healthcare professional.

• Assess kidney function and electrolyte levels, particularly potassium.
• Monitor blood pressure regularly to avoid excessive lowering.
• Use caution in patients with liver disease or heart block.
• Discuss any history of angioedema or allergic reactions to ARBs.
• Pregnant or breastfeeding individuals should consult a physician, as safety data are limited.
• Inform the prescriber of any planned surgery or procedures, as blood pressure may need adjustment.

Golasan can interact with other medicines, affecting its efficacy or safety profile.

Avoid

• Concomitant use with aliskiren in patients with diabetes or renal impairment.
• Potassium‑supplementing agents or potassium‑sparing diuretics that may cause hyperkalemia.
• Strong CYP2C9 inhibitors (e.g., fluconazole) that can increase losartan levels.

Use with caution

• Non‑steroidal anti‑inflammatory drugs (NSAIDs) that may reduce antihypertensive effect.
• Lithium, as losartan may increase lithium concentrations.
• Other antihypertensives (e.g., ACE inhibitors, beta‑blockers) requiring dose adjustments.
• Diuretics, especially thiazides, which may affect electrolyte balance.
