Captopril Arrow (Captopril)

Captopril Arrow is prescribed for several cardiovascular conditions where inhibition of the renin‑angiotensin system is beneficial.

• Management of hypertension (high blood pressure).
• Treatment of chronic heart failure to improve symptoms and outcomes.
• Post‑myocardial infarction therapy to reduce mortality.
• Adjunct therapy for diabetic nephropathy when indicated.
• Off‑label use may include certain renal disorders under specialist supervision.

Captopril Arrow may cause a range of side effects, most of which are mild and transient. Serious adverse reactions are less common but require medical attention.

Common

• Dry cough.
• Taste disturbances or metallic taste.
• Dizziness or light‑headedness, especially after standing.
• Headache.
• Nausea or mild gastrointestinal upset.
• Rash or mild skin irritation.

Serious

• Angioedema (swelling of face, lips, tongue, or throat).
• Severe hypotension (dangerously low blood pressure).
• Hyperkalemia (elevated blood potassium levels).
• Acute kidney injury or worsening renal function.
• Hepatic dysfunction or jaundice.
• Neutropenia or agranulocytosis (low white blood cell counts).

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

• Assess renal function; dose adjustment may be needed in impaired kidneys.
• Monitor serum potassium and electrolytes, especially if taking potassium‑sparing diuretics.
• Caution in patients with a history of angioedema or hereditary angioedema.
• Use carefully in pregnant or breastfeeding women; discuss risks with a physician.
• Avoid abrupt discontinuation; tapering may be required to prevent rebound hypertension.
• Inform the prescriber of any liver disease or recent cardiac surgery.

Captopril Arrow can interact with several drug classes, influencing its efficacy or safety profile.

Avoid

• Concurrent use with other ACE inhibitors, ARBs, or direct renin inhibitors due to additive hypotensive effects.
• Potassium supplements or potassium‑sparing diuretics, which may cause hyperkalemia.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs) that can reduce antihypertensive response and affect kidney function.

Use with caution

• Diuretics, especially thiazides, may increase the risk of hypotension.
• Lithium, as captopril can raise lithium levels and risk toxicity.
• Certain antibiotics (e.g., trimethoprim‑sulfamethoxazole) that affect renal clearance.
• Antidiabetic agents, since blood pressure changes may alter glucose control.
