ATC Classification
Losartan is classified under the ATC code C09CA01. This indicates it is part of the angiotensin II receptor blockers (ARBs). ARBs are vital components of the antihypertensive medication arsenal, working directly on the cardiovascular system.
Registration and Approval
In Canada, Losartan is classified as prescription-only medication, a status reinforced by regulatory approvals from Health Canada, along with approvals from international bodies such as the FDA and EMA. This ensures its use and distribution align with strict safety standards, fortifying its acceptance in the treatment landscape.
Dosage & Administration of Losartan
Understanding how to properly use Losartan is crucial for managing conditions like hypertension, diabetic nephropathy, and heart failure. The typical starting dose for adults dealing with hypertension is 50 mg once daily. For cases of diabetic nephropathy, the same starting dose of 50 mg can be applicable, while in managing heart failure, starting at 12.5 mg is common, with adjustments made as tolerated.
Dosage adjustments are vital based on patient demographics and health conditions. For children aged 6 to 16 years, the recommended starting dose is about 0.7 mg/kg, up to a maximum of 50 mg daily. Elderly patients may also need a careful approach; starting at a lower dose is often more appropriate, particularly if they're frail. Those with liver impairment usually begin at 25 mg due to altered metabolism.
Regarding treatment duration, Losartan generally involves chronic use for effective management of hypertension and other conditions. Most patients may expect to see optimal results within six weeks of consistent dosing. It’s important to store Losartan at room temperature, away from moisture and heat, to maintain its efficacy.

Absolute contraindications include known hypersensitivity to the drug or its components, severe liver impairment, and during pregnancy, particularly in the later trimesters due to risks to fetal health.

Guidelines for Proper Use of Losartan
Taking Losartan correctly is crucial for optimal effectiveness in managing health conditions. Patients are advised to take this medication at the same time each day, with or without food. Consistency helps maintain stable blood levels of the drug. It’s essential to follow the prescribed dosage guidelines to avoid any potential side effects.
There are a few things to avoid while taking Losartan:
- Avoid alcohol consumption, as it can amplify the blood pressure-lowering effects.
- Be cautious with non-steroidal anti-inflammatory drugs (NSAIDs), which can hinder the effectiveness of Losartan.
Storage is important for maintaining the medication's integrity. Losartan should be stored in a cool, dry place, ideally at room temperature between 20 to 25°C (68 to 77°F). Patients must protect it from moisture and excessive heat, and refrigeration is not recommended.
Common mistakes that patients might make include mismanaging dosage timing, which can lead to missed doses or double dosing. It's vital to adhere to the prescribed regimen and consult healthcare providers for personalized adjustments. A reminder to read the patient leaflet thoroughly cannot be understated, as it contains critical information specific to individual health situations. Following additional instructions from healthcare professionals can enhance safety and efficacy.
