What’s Inside & How It Works

Ingredients Overview

Keftab, also known as Cephalexin, is a widely used antibiotic with several active and inactive ingredients. The primary active component is cephalexin, which falls under the first-generation cephalosporin class of antibiotics. Inactive ingredients may include starch, magnesium stearate, and various color additives. Patients should be cautious, as Keftab can trigger allergic reactions in those with a known hypersensitivity to cephalosporins or penicillin. Watch out for potential allergens like lactose or certain artificial colors, which may cause discomfort in sensitive individuals.

Mechanism Basics

Keftab works by targeting and disrupting the bacterial cell wall synthesis. As a beta-lactam antibiotic, it binds to specific penicillin-binding proteins within the bacteria, ultimately leading to cell lysis and death. This mechanism is particularly effective against a variety of gram-positive and some gram-negative bacteria. Keftab's action is essential in treating bacterial infections, as it stops bacteria from multiplying and helps the body's immune system to clear the infection effectively.

Main Indications

Approved Uses in Canada

Health Canada's approval of Keftab includes a variety of indications. It's primarily used for respiratory infections such as pneumonia and bronchitis, skin infections like cellulitis, and urinary tract infections (UTIs). For example, Keftab is often prescribed when there is a need to combat bacterial pathogens effectively in these common areas. Its versatility makes it a go-to medication in different clinical settings, ensuring that patients receive the necessary treatment for their infections.

Off-label Uses by Canadian Physicians

In addition to its approved uses, Keftab is sometimes prescribed off-label for conditions like dental prophylaxis before certain procedures and to treat bone infections. This off-label use arises from cephalexin's effectiveness in tackling specific bacterial strains that may not be straightforward to treat with other antibiotics. Physicians often lean on clinical experience and emerging evidence to guide these decisions, especially when standard treatments may not be suitable or effective.

Interaction Warnings

Food Interactions (Alcohol, Caffeine)

Patients taking Keftab should be aware of potential food interactions. While alcohol does not specifically decrease Keftab’s effectiveness, it can exacerbate side effects like nausea and dizziness. Caffeine might also have an impact, as it can increase some side effects when taken in excessive amounts alongside Keftab. A cautious approach is advisable, keeping consumption of these substances moderate to ensure the best therapeutic experience.

Drug Conflicts (Health Canada Database)

Critical interactions have been recorded in the Health Canada database. For instance, Keftab's effectiveness may be reduced when taken with certain antacids containing aluminum or magnesium. Additionally, other medications that affect renal function could increase the risk of cephalexin toxicity. It's crucial for patients on multiple medications (polypharmacy) to consult healthcare providers to prevent adverse effects and ensure safe usage.

Latest Evidence & Insights

Recent clinical studies have reinforced Keftab's effectiveness in treating common bacterial infections, emphasizing its safety and resistance patterns. Research indicates that while resistance to cephalosporins is on the rise, Keftab remains highly effective against many sensitive strains of bacteria. Consider the following table summarising pivotal study findings:
