It is widely prescribed for a diverse range of conditions, including respiratory tract infections (like atypical pneumonia), sexually transmitted infections (such as chlamydia), tick-borne diseases (like Lyme disease), and as a long-term treatment for moderate to severe acne and rosacea.
Ciprofloxacin
Ciprofloxacin is a prominent, second-generation fluoroquinolone antibiotic. It is characterised by its broad-spectrum bactericidal activity, particularly against Gram-negative bacteria. It is frequently utilised for treating a variety of challenging infections, including complicated urinary tract infections, severe gastroenteritis, bone and joint infections, and certain types of respiratory tract infections.
Levofloxacin
Levofloxacin is a potent, broad-spectrum fluoroquinolone antibiotic. It is highly effective against a wide array of both Gram-positive and Gram-negative bacteria. Due to its strength and potential for serious side effects, it is typically reserved for treating severe, complicated, or difficult-to-treat infections, such as severe pneumonia, acute bacterial exacerbation of chronic bronchitis, and complicated urinary tract infections, when alternative treatments are ineffective.
Cefalexin
Cefalexin is a widely used, first-generation cephalosporin antibiotic. It is highly valued for its excellent oral absorption and robust efficacy against Gram-positive bacteria, particularly staphylococci and streptococci. It is a cornerstone treatment for uncomplicated skin and soft tissue infections, as well as straightforward urinary tract infections.
Cefuroxime
Cefuroxime is a highly versatile, second-generation cephalosporin antibiotic. It offers a broader spectrum of antibacterial activity compared to first-generation cephalosporins, making it particularly effective against certain strains of bacteria that produce beta-lactamase. It is frequently prescribed as a reliable alternative for treating respiratory tract infections, ear infections, and urinary tract infections.
Clarithromycin
Clarithromycin is an advanced macrolide antibiotic, structurally related to erythromycin but with improved acid stability and a broader spectrum of activity. It is widely utilised for treating various respiratory tract infections, skin infections, and plays a pivotal, indispensable role as a core component in multidrug regimens aimed at eradicating Helicobacter pylori (H. pylori) to treat peptic ulcer disease.
Azithromycin
Azithromycin is a broad-spectrum macrolide antibiotic renowned for its unique pharmacokinetic properties, which allow for a short and convenient dosing schedule. It is highly effective against a wide range of bacteria and is frequently prescribed for upper and lower respiratory tract infections, skin infections, and certain sexually transmitted diseases like chlamydia.
Amoxicillin
Amoxicillin is a widely prescribed, moderate-spectrum, bactericidal beta-lactam antibiotic belonging to the aminopenicillin family. It is considered a crucial first-line treatment for a broad variety of common bacterial infections in both paediatric and adult populations, highly valued for its efficacy, favourable safety profile, and relatively low cost.
