Augmentin: Uses, Benefits, Dosage, Side Effects & How to Deal with Them
Augmentin, a combination antibiotic, has an interesting history that begins with the discovery of penicillin, one of the most groundbreaking antibiotics in medical history.
Penicillin, the first widely used antibiotic, was discovered by Sir Alexander Fleming in 1928. Fleming observed that a mold called Penicillium notatum had the ability to kill bacteria, leading to the development of the antibiotic penicillin.
In the 1970s, scientists discovered a derivative of penicillin known as amoxicillin. Amoxicillin is a broad-spectrum antibiotic belonging to the penicillin group, which effectively targets a wide range of bacterial infections. It became a popular choice for treating various bacterial infections due to its effectiveness, safety, and low incidence of side effects.
Researchers recognized that certain bacteria produce enzymes called beta-lactamases, which can break down and inactivate penicillin antibiotics. This discovery led to the development of clavulanic acid, a compound that inhibits these enzymes. Clavulanic acid is not effective as an antibiotic on its own but serves as a crucial addition to certain penicillin-based antibiotics.
In 1981, GlaxoSmithKline (GSK) introduced Augmentin as a combination of amoxicillin and clavulanic acid. The addition of clavulanic acid in Augmentin helped to overcome bacterial resistance mechanisms by inhibiting the beta-lactamases produced by some bacteria. This combination made Augmentin effective against a broader range of bacterial infections, including those caused by beta-lactamase-producing bacteria.
Augmentin quickly gained popularity and became a widely prescribed antibiotic. It is commonly used to treat various bacterial infections, such as respiratory tract infections, sinusitis, otitis media (ear infections), urinary tract infections, skin and soft tissue infections, and more. Augmentin is especially useful when the specific bacteria causing the infection are unknown or when there is a higher likelihood of encountering resistant bacteria.
Dosage Forms
Augmentin is available in several dosage forms to accommodate different patient needs and treatment requirements. The specific dosage form prescribed may depend on factors such as the patient’s age, the severity of the infection, and the route of administration preferred. Here are the common dosage forms of Augmentin:
1. Tablets: Augmentin tablets are one of the most commonly prescribed forms. They come in various strengths, typically containing a fixed ratio of amoxicillin to clavulanic acid. The tablets are designed to be swallowed whole with water and are available in different strengths, such as 250 mg/125 mg, 500 mg/125 mg, and 875 mg/125 mg.
2. Chewable Tablets: These tablets are formulated for children or those who have difficulty swallowing regular tablets. Chewable tablets offer the convenience of being chewed or crushed before swallowing, making them more suitable for pediatric patients. They also come in different strengths, such as 200 mg/28.5 mg and 400 mg/57 mg.
3. Powder for Oral Suspension: Augmentin is available in powder form, which can be reconstituted with water to prepare an oral suspension. This formulation is commonly used in pediatric patients or individuals who have difficulty swallowing tablets. The powder for oral suspension comes in different concentrations, such as 125 mg/31.25 mg per 5 mL and 200 mg/28.5 mg per 5 mL, allowing for accurate dosing based on the patient’s weight.
4. Extended-Release Tablets: Augmentin also comes in extended-release tablet formulations, which provide a sustained release of the active ingredients over a longer period. These tablets are typically taken once or twice daily, depending on the specific strength prescribed. Extended-release tablets offer the advantage of reduced dosing frequency and may be preferred for certain infections or patient populations.
5. Intravenous (IV) Formulations: In more severe cases or when oral administration is not feasible, Augmentin is available in intravenous formulations. These formulations are administered directly into the bloodstream through a vein and are commonly used in hospital settings. Intravenous Augmentin is typically reserved for severe infections or situations where oral medications cannot be used.
It is important to note that the specific dosage form and strength prescribed will depend on the patient’s condition, age, weight, and the judgment of the healthcare professional.
