This medicine inhibits the angiotensin-converting enzyme. Lower angiotensin II and aldosterone levels reduce vascular resistance and sodium retention. That supports lower blood pressure and reduces workload on the heart.

Also marketed under a brand name such as Capoten® in some regions.

Therapy is usually started at a low dose and adjusted by your prescriber. Some regimens include captopril 25 mg as part of a stepwise titration. Effects build with steady use and regular monitoring rather than a single dose.

Who It’s For

This treatment is indicated for adults with essential hypertension. It may be used alone or with thiazide diuretics when additional control is needed. It is also indicated for heart failure in combination with diuretics and digitalis, and for improving survival after myocardial infarction with left ventricular dysfunction. In insulin-dependent diabetes with proteinuric nephropathy, this class can slow kidney function decline.

Do not use during pregnancy. Avoid if you have a history of ACE inhibitor–related angioedema or hereditary angioedema. Use caution with renal artery stenosis, dehydration, or severe renal impairment. Your prescriber may review baseline kidney function and potassium before starting.

Posología y utilización

Take tablets by mouth exactly as prescribed. Food reduces absorption; the label recommends taking doses one hour before meals for consistent exposure. Most plans use two or three daily doses spaced evenly. Swallow with water and take at the same times each day.

Some patients are prescribed the captopril 25 mg tablet during titration; follow your prescriber’s schedule. Do not change your dose based on home readings without medical guidance. If dizziness occurs at initiation, sit or lie down until it passes and contact your prescriber if it persists.

Do not place tablets under the tongue unless your prescriber has specifically directed that method for you. Avoid potassium salt substitutes or high-potassium diets unless approved.

Fortalezas y formas

Oral tablets are commonly available in multiple strengths. Color and scoring can vary by manufacturer. Availability may differ by pharmacy.

• Comprimidos de 12,5 mg
• Comprimidos de 25 mg
• Comprimidos de 50 mg
• Comprimidos de 100 mg

Brand examples in some markets include Capoten 25 mg. Generics are widely used and considered therapeutically equivalent when approved.

Dosis omitida y momento oportuno

If you miss a dose, take it when you remember unless it is close to the next dose. If it is nearly time for the next dose, skip the missed dose and resume the regular schedule. Do not double up to catch up. Keep doses evenly spaced and take them before meals as directed on the label.

Almacenamiento y viaje

Store in the original container with the lid tightly closed. Keep tablets in a dry place at typical room temperatures and away from excess heat and humidity. Do not store in the bathroom. Keep out of reach of children and pets.

When traveling, pack your tablets in carry-on luggage with the pharmacy label attached. Bring a copy of your prescription and a medication list. Keep doses on your normal schedule across time zones; a pill organizer with alarms can help. Do not leave medicine in a hot car. If your prescriber requests lab work, schedule it ahead of extended travel.

Beneficios

This class lowers cardiovascular risk by reducing systemic vascular resistance. It can reduce symptoms in heart failure when combined with other standard therapies. After myocardial infarction, use in eligible patients with left ventricular dysfunction can improve outcomes. In adults with insulin-dependent diabetes and proteinuric nephropathy, it may slow renal disease progression.

Efectos secundarios y seguridad

• Tos seca y persistente
• Mareos o aturdimiento, especialmente al empezar a tomar medicamentos
• Dolor de cabeza o fatiga
• Change in taste (metallic or decreased taste)
• Erupción o picor
• Molestias gastrointestinales

Serious reactions can occur but are less common. Angioedema (rapid swelling of face, lips, tongue, or throat) requires emergency care. Kidney function changes and high potassium may occur, especially with dehydration or interacting medicines. Rare events include neutropenia and liver injury. Seek urgent help for severe swelling or trouble breathing, and contact your prescriber for dark urine, jaundice, or persistent vomiting.

Interacciones medicamentosas y precauciones

• Diuretics: may increase the risk of low blood pressure when starting therapy
• Potassium-sparing diuretics or potassium supplements: increase hyperkalemia risk
• NSAIDs: can reduce antihypertensive effect and affect kidney function
• Lithium: risk of elevated lithium levels and toxicity
• ARBs or aliskiren: dual renin–angiotensin system blockade raises adverse event risk
• Neprilysin inhibitors (sacubitril/valsartan): allow adequate washout before switching
• mTOR inhibitors or racecadotril: increased angioedema risk reported with ACE inhibitors

Alcohol can enhance blood pressure–lowering effects and dizziness. Inform your prescriber about all medicines, supplements, and herbal products before starting.

Qué esperar con el tiempo

Blood pressure typically declines gradually with consistent dosing. Dizziness may be more noticeable early in therapy, especially if you are volume depleted. A dry cough can appear and may require a change to another class if persistent and bothersome. Your prescriber may periodically check kidney function and potassium. Keep lifestyle measures in place, including reduced sodium intake, activity as advised, and adherence to other prescribed therapies.

Comparar con alternativas

Other options in the same therapeutic area include agents with once-daily dosing or different mechanisms. An ACE inhibitor alternative, Lisinopril, may suit patients needing simplified schedules. An angiotensin receptor blocker, Irbesartán, offers a similar blood pressure effect without ACE-related cough in many patients. Selection depends on comorbidities, prior reactions, and prescriber guidance.

Disponibilidad y sustituciones

Supply can vary by manufacturer and strength. If a specific presentation is not available, your prescriber may recommend a therapeutically equivalent alternative. If 25 mg captopril is out of stock, another strength or a related agent may be suitable with appropriate instructions.

Adecuación al paciente y consejos para ahorrar costes

This therapy may fit adults with hypertension, certain heart failure regimens, or post–myocardial infarction care with left ventricular dysfunction. It is not appropriate in pregnancy or in patients with prior ACE inhibitor–related angioedema. Severe renal impairment requires close supervision and lab monitoring.

• Multi-month fills: a 60- to 90-day supply can reduce pharmacy trips
• One pharmacy: refill at the same location to simplify oversight
• Set reminders: phone alerts help maintain timing before meals
• Lab planning: schedule renal and potassium checks on time
• Lifestyle: continue sodium restriction and activity as advised
