List Of Antibiotics That Start With I

antibiotics that start with i

1. Isoniazid (INH)

Overview

Isoniazid, a first-line antitubercular medication, is pivotal in the treatment of tuberculosis (TB). It functions by inhibiting the synthesis of mycolic acids in the bacterial cell wall, essential for the survival of Mycobacterium tuberculosis.

Mechanism Of Action

Isoniazid targets the enzyme enoyl-acyl carrier protein reductase (InhA), hindering the synthesis of mycolic acids. Mycolic acids are vital for the structural integrity of the mycobacterial cell wall, and by disrupting this process, Isoniazid effectively suppresses the growth and multiplication of the bacteria.

Uses

Primarily used in the treatment of TB, Isoniazid is often part of combination therapies to prevent the development of drug-resistant strains. It is commonly employed in both active TB treatment and latent TB infection prophylaxis.

Side Effects

While Isoniazid is generally well-tolerated, it may lead to adverse effects such as hepatotoxicity, peripheral neuropathy, and allergic reactions. Monitoring liver function is crucial during treatment.

2. Imipenem-Cilastatin

Overview

Imipenem-Cilastatin is a broad-spectrum carbapenem antibiotic renowned for its efficacy against a wide range of bacteria, including both Gram-positive and Gram-negative strains. It is often used in hospital settings for severe infections.

Mechanism Of Action

As a beta-lactam antibiotic, Imipenem-Cilastatin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs). The cilastatin component protects Imipenem from renal dehydropeptidase I, extending its half-life and enhancing its antibacterial activity.

Uses

Imipenem-Cilastatin is employed in the treatment of complicated intra-abdominal infections, pneumonia, skin and soft tissue infections, and urinary tract infections. Its broad spectrum of activity makes it a valuable tool in combating multidrug-resistant bacterial strains.

Side Effects

Common side effects include nausea, vomiting, and diarrhea. However, severe reactions such as seizures and allergic reactions may occur. Close monitoring is necessary during administration.

3. Ibuprofen

Overview

While not a traditional antibiotic, ibuprofen is included here due to its role in combination therapies. It is a nonsteroidal anti-inflammatory drug (NSAID) with antimicrobial properties that enhance the effectiveness of antibiotics.

Mechanism Of Action

Ibuprofen exerts its antimicrobial effects by inhibiting the enzyme fatty acid synthase (FAS), crucial for bacterial membrane synthesis. When combined with antibiotics, particularly beta-lactams, it can enhance bacterial susceptibility to these drugs.

Uses

In combination with antibiotics, ibuprofen is explored for its potential in treating bacterial infections. Research suggests that the synergy between ibuprofen and antibiotics may improve treatment outcomes, especially in cases of antibiotic-resistant bacteria.

Side Effects

Common side effects of ibuprofen include gastrointestinal issues, such as stomach pain and indigestion. Prolonged use may lead to more severe complications like kidney problems and cardiovascular issues.

4. Isavuconazonium

Overview

Isavuconazonium is a prodrug that, when metabolized, becomes isavuconazole – a triazole antifungal agent. It is used for the treatment of invasive fungal infections, particularly in patients intolerant of or refractory to other antifungal therapies.

Mechanism Of Action

Isavuconazole inhibits the enzyme lanosterol 14α-demethylase, a critical step in the synthesis of ergosterol – an essential component of the fungal cell membrane. By disrupting membrane integrity, it hinders fungal growth and propagation.

Uses

Isavuconazonium is employed in the treatment of invasive aspergillosis and mucormycosis, challenging fungal infections that often afflict immunocompromised patients. Its broad spectrum of activity extends to various fungal strains.

Side Effects

Common side effects include nausea, headache, and elevated liver enzymes. Serious adverse reactions such as allergic reactions and hepatotoxicity may occur, necessitating careful monitoring.

5. Ivermectin

Overview

Ivermectin is an antiparasitic medication widely used to treat infections caused by various parasitic organisms, including certain worms and arthropods. While not an antibiotic, it is included here due to its significance in combating parasitic infections.

Mechanism Of Action

Ivermectin acts by binding to glutamate-gated chloride ion channels in the nervous system of parasites, leading to increased permeability and paralysis. This results in the expulsion of parasites from the host.

Uses

Ivermectin is employed in the treatment of parasitic infections such as onchocerciasis (river blindness), strongyloidiasis, and lymphatic filariasis. It is also utilized in veterinary medicine to control parasites in animals.

Side Effects

Adverse effects are generally mild and include dizziness, nausea, and skin rash. In rare cases, more severe reactions such as neurotoxicity may occur.
