Keflex

Keflex, also known by its generic name cephalexin, is a widely prescribed antibiotic that belongs to the cephalosporin class of drugs. It is commonly used to treat a variety of bacterial infections, including skin infections, respiratory infections, and urinary tract infections.

Chemical Structure and Classification, Keflex

Keflex is a semi-synthetic antibiotic derived from the natural antibiotic cephalosporin C. Its chemical structure is characterized by a beta-lactam ring, which is essential for its antibacterial activity. Cephalexin is classified as a first-generation cephalosporin, meaning it has a broad spectrum of activity against gram-positive bacteria, including *Staphylococcus aureus*, *Streptococcus pyogenes*, and *Streptococcus pneumoniae*. It also exhibits some activity against gram-negative bacteria, such as *Escherichia coli* and *Proteus mirabilis*.

Mechanism of Action

Keflex exerts its antibacterial effect by inhibiting the synthesis of peptidoglycan, a key component of bacterial cell walls. This inhibition prevents bacteria from building and maintaining their cell walls, ultimately leading to cell lysis and death. Specifically, cephalexin binds to and inhibits the activity of bacterial transpeptidases, also known as penicillin-binding proteins (PBPs). These enzymes are crucial for the formation of peptide cross-links in peptidoglycan, which provides structural integrity to the bacterial cell wall. By blocking the activity of these enzymes, Keflex disrupts the synthesis of peptidoglycan, resulting in weakened cell walls and bacterial death.

Forms and Uses

Keflex is available in various forms, including:

• Oral capsules: The most common form, convenient for oral administration. These capsules are typically taken every 6 hours with a full glass of water.
• Oral suspension: This liquid form is particularly useful for children and individuals who have difficulty swallowing capsules.
• Intravenous solution: For severe infections or when oral administration is not possible, Keflex can be administered intravenously.

The choice of formulation depends on the severity of the infection, patient preference, and the ability to swallow medications.

Dosage and Administration

The recommended dosage of Keflex varies depending on the type of infection, patient age, weight, and kidney function. It is crucial to consult with a healthcare professional to determine the appropriate dosage and duration of treatment.

• Adults: The typical dosage for adults is 250-500 mg every 6 hours. For severe infections, the dosage may be increased to 1 gram every 6 hours.
• Children: The dosage for children is based on weight, typically 25-50 mg/kg per day, divided into four doses.

Keflex is usually administered orally, but in cases of severe infections or when oral administration is not possible, it can be given intravenously.

Important Considerations

• Allergic reactions: Like other antibiotics, Keflex can cause allergic reactions in some individuals. Signs of an allergic reaction include rash, itching, swelling, and difficulty breathing. If you experience any of these symptoms, stop taking Keflex immediately and seek medical attention.
• Gastrointestinal side effects: Common side effects of Keflex include nausea, vomiting, diarrhea, and stomach cramps. These side effects are usually mild and often resolve on their own.
• Kidney function: Keflex is primarily excreted by the kidneys. Individuals with impaired kidney function may require dosage adjustments to prevent drug accumulation and potential toxicity.
• Drug interactions: Keflex can interact with certain medications, including those that affect blood clotting, diuretics, and certain types of antibiotics. It is important to inform your healthcare provider about all medications you are taking, including over-the-counter drugs and herbal supplements.

However, Keflex may be preferred for certain infections, particularly those involving specific bacterial strains or when doxycycline is contraindicated.

Pharmacokinetic Profile of Keflex

Keflex, or cephalexin, is a cephalosporin antibiotic that is widely used to treat bacterial infections. Its pharmacokinetic profile, which encompasses its absorption, distribution, metabolism, and elimination, is crucial for understanding its therapeutic efficacy and potential side effects.

Absorption

Cephalexin is well absorbed from the gastrointestinal tract after oral administration. Its bioavailability, which refers to the fraction of the drug that reaches systemic circulation, is approximately 90%. The rate and extent of absorption may be affected by the presence of food, with lower peak plasma concentrations observed when Keflex is taken with meals.

Distribution

Once absorbed, cephalexin is distributed throughout the body, primarily to the interstitial fluid and tissues. It penetrates well into most body fluids, including the cerebrospinal fluid, but to a lesser extent in the presence of inflammation. Keflex binds to plasma proteins to a moderate extent, with a protein binding of around 15-25%. This binding can influence its distribution and elimination.

Metabolism

Cephalexin undergoes minimal metabolism in the liver. It is primarily eliminated unchanged in the urine.

Elimination

The elimination half-life of cephalexin is approximately 0.5-2 hours in adults with normal renal function. This means that it takes about 0.5-2 hours for the concentration of the drug in the body to decrease by half. Renal excretion is the primary route of elimination, with approximately 90% of the administered dose being excreted unchanged in the urine.

Influence of Age, Renal Function, and Hepatic Function

Several factors can influence the pharmacokinetics of Keflex, including age, renal function, and hepatic function.

Age

The pharmacokinetics of Keflex may be altered in older adults, as their renal function may decline with age. This can lead to increased drug accumulation and a higher risk of adverse effects.
