Altace 10 mg Capsules

Brand Name

This medication is marketed under the trade name Altace, a label widely recognized among healthcare professionals for its cardiovascular applications.

International Nonproprietary Name (INN)

The active ingredient in this drug is known globally as ramipril, providing a standardized identifier across medical communities worldwide.

Form of Release

The medication is available as capsules, designed for oral administration with various strengths to suit individual patient needs. This encapsulated form ensures ease of use and stability under normal storage conditions.

Composition

Ramipril serves as the primary active substance, engineered to target specific physiological processes. Supporting components include pregelatinized starch, gelatin, and titanium dioxide, which shape the capsule and facilitate its breakdown in the body. Minor additives, such as colorants or stabilizers, maintain product consistency and longevity. These elements work together to support ramipril’s therapeutic action without altering its effectiveness.

Pharmacologic Properties

Pharmacodynamics

This drug functions as an angiotensin-converting enzyme (ACE) inhibitor, modulating the renin-angiotensin-aldosterone system to manage blood pressure and fluid levels. It prevents angiotensin I from converting to angiotensin II, reducing vessel constriction and aldosterone production, which relaxes blood vessels and lowers sodium retention. This action decreases blood pressure and reduces cardiac strain, making it valuable for hypertension and heart support. Effects emerge gradually, with benefits noticeable within hours and stabilizing over weeks. Ramipril also offers vascular endothelium protection, enhancing long-term cardiovascular wellness.

Pharmacokinetics

Upon ingestion, the medication absorbs from the digestive tract, achieving about 60% bioavailability due to initial liver metabolism. Food delays absorption slightly but doesn’t significantly affect efficacy. Ramipril, a prodrug, transforms quickly in the liver into ramiprilat, its active form, peaking in plasma within two to four hours. This metabolite spreads widely, moderately binding to plasma proteins and reaching key tissues like the heart and kidneys. It exits mainly through urine, with roughly 60% as ramiprilat and other metabolites, while the half-life ranges from 13 to 17 hours, extending in renal impairment. A smaller portion leaves via feces, reflecting biliary elimination.

Indications for Use

The medication addresses multiple cardiovascular-related conditions. It’s a primary choice for hypertension, normalizing elevated blood pressure effectively. It also supports heart failure management, especially post-myocardial infarction, by easing cardiac workload and boosting survival odds. High-risk patients, such as those with coronary artery disease or diabetes, benefit from its preventive vascular effects. Additionally, it helps manage renal issues like proteinuric nephropathy by lowering glomerular pressure and slowing progression, proving its utility across acute and chronic scenarios.

Contraindications

Certain conditions bar the use of this drug to prevent serious complications. Hypersensitivity to ramipril, other ACE inhibitors, or capsule ingredients prohibits its use, as reactions could range from rashes to anaphylaxis. A history of angioedema, whether from prior ACE inhibitor exposure or genetic factors, excludes it due to swelling risks. Bilateral renal artery stenosis or single-kidney stenosis contraindicates it, as reduced blood flow might worsen kidney function. Severe renal impairment, with creatinine clearance below 20 mL/min, limits its use unless dialysis mitigates risks. Pregnancy in the second or third trimester also rules it out due to fetal harm potential.

Method of Administration and Dosage

How to Take

Capsules are taken orally, with or without food, though regular timing helps maintain consistent levels. Swallowing them whole with water ensures proper stomach delivery. Breaking or chewing is discouraged to preserve absorption patterns.

Dosage for Adults and Children

Adults treating hypertension typically start with 2.5 mg daily, increasing to 5 mg or 10 mg as needed, up to 20 mg daily in divided doses if required. For heart failure after infarction, 2.5 mg twice daily is common, titrated to 5 mg twice daily if tolerated. Pediatric use is less common, but when prescribed, doses begin at 0.1 mg per kilogram daily, adjusted carefully under expert care. Blood pressure checks guide these increments for safety and efficacy.

Dose Adjustment in Specific Conditions

Renal impairment calls for lower starting doses, like 1.25 mg daily, with cautious increases if clearance is 20 to 60 mL/min. Liver dysfunction may slow metabolism, requiring conservative dosing and function monitoring. Elderly or dehydrated patients might need reduced amounts to avoid excessive blood pressure drops. Adjustments ensure therapeutic gains without organ strain.

Side Effects

The medication can cause various unintended effects, differing in occurrence and intensity. A dry cough, tied to bradykinin buildup, is frequent but may subside if stopped. Hypotension, especially initially, might lead to dizziness or lightheadedness, notably in dehydrated individuals. Hyperkalemia could arise, causing muscle cramps or heart rhythm issues, needing attention in susceptible groups. Nausea or abdominal discomfort affects some but often fades. Rare severe reactions, like angioedema—swelling of the face or throat—or acute kidney failure, require urgent care. Routine monitoring catches these early.

Overdose

Symptoms of Overdose

Excessive intake may trigger severe hypotension, leading to weakness, fainting, or shock from overly relaxed vessels. Bradycardia might occur, destabilizing heart function. Hyperkalemia could cause muscle weakness or arrhythmias, while kidney function might drop sharply in extreme cases. Symptoms typically appear within hours and worsen without action, reflecting potent systemic impact.

First Aid Measures

Stop the drug immediately in an overdose and seek prompt medical help. Recent ingestion may warrant gastric lavage or charcoal under supervision to limit absorption. IV saline can address low blood pressure, while heart and potassium monitoring corrects imbalances. Dialysis is rare but may aid severe renal cases. Stabilization prioritizes restoring pressure and organ function.

Drug Interactions

Effects on Other Medications

This drug affects other medications’ performance when combined. It enhances antihypertensive effects, risking steep pressure drops, so doses may need tweaking. NSAIDs might reduce its efficacy and stress kidneys, a concern with long-term use. Potassium-sparing diuretics or supplements raise hyperkalemia odds, needing electrolyte checks. Lithium levels may climb, risking toxicity, while antidiabetic drugs could see heightened hypoglycemia, requiring glucose monitoring.

Compatibility with Alcohol and Food

Alcohol can intensify the medication’s blood pressure-lowering effects, increasing dizziness risks, so moderation is wise. Food doesn’t notably affect absorption, but high-salt intake might counter its benefits, suggesting dietary moderation. Potassium-rich foods, like avocados, need care to avoid excess potassium buildup.

Special Precautions

Use During Pregnancy and Breastfeeding

The drug is barred beyond the first trimester of pregnancy due to risks of fetal kidney damage or death, based on evidence. Nursing mothers should avoid it, as ramipril enters breast milk and might affect infant kidneys; alternatives are safer during lactation.

Impact on Driving and Machinery Operation

Dizziness or fatigue, especially at the start, may hinder driving or machinery use. Patients should assess their response before such tasks to ensure safety.

Considerations for Elderly and Pediatric Populations

Older adults may need lower initial doses due to slower kidney clearance, with monitoring for pressure or renal shifts. In children, use is rare and specialist-guided, with precise dosing to avoid developmental effects. Tailored care ensures optimal outcomes.
