Anti Infective Drugs & Medicines

Anti Infective Drugs & Medicines: Classification

Anti-infective are pharmaceuticals used to treat or prevent infections; they can be categories into four types

a. Bacteria anti infective Drugs
b. Viruses anti infective drugs
c. Fungi anti infective Drugs
d. Parasites anti infective Drugs

Since their discovery, anti-infective have changed the medical field. They are now essential for treating and even preventing many different types of infection.

a. Aside from treating common colds and flu, antibiotics can also be used to treat and frequently completely eradicate more dangerous infections like pneumonia and tuberculosis.
b. Carry out both simple and sophisticated surgical procedures, including those with a high potential for infection such cesarean sections and joint replacements.
c. Chemotherapy and other immunosuppressive treatments are essential for cancer patients.

Antimicrobial resistance is a serious problem, reducing the efficacy of several anti-infectives (AMR).

Types of Anti-Infective Drugs & Medicines

1. Amebicides

Agents that kill or destroy amoebae are called "amebicides." Different types of amecides work in various ways. Humans and animals alike can benefit from their use, as they kill off amebae that cause disease.

2. Penicillins

Antibiotics called penicillins are isolated from the Penicillium fungus. When taken orally, antibiotics reduce or eliminate bacterial growth.

3. Oxazolidinon Antibiotics

The ribosomal 50S subunit of bacteria is targeted by oxazolidinone antibiotics, a type of synthetic antibacterial medicines. That's bad news because reproducing bacteria needs the 70S initiation complex to develop.

4. Miscellaneous Antibiotics

The term "miscellaneous antibiotics" refers to antibiotics that are the sole treatment option for their respective infections. Antibiotics from a wide variety of classes are used to treat illnesses brought on by bacteria and other organisms that are vulnerable to the drugs they are designed to combat.

5. Macrolide derivatives

Antibiotics belonging to the macrolide class are produced by streptomycetes. They are large-ring lactones found in nature, containing anywhere from 14 to 20 atoms in the ring. Macrolides prevent protein synthesis in bacteria by binding to the 50S component of the ribosome and blocking ribosomal translocation.

6. Lincomycin Derivatives

Protein synthesis is crucial to bacterial survival, and lincomycin derivatives are one of the few classes of antibiotics that work against this process. When dealing with infections caused by sensitive strains of pneumococci, staphylococci, or streptococcus, only lincomycin derivatives should be used.

7. Leprostatics

The expansion of Mycobacterium leprae, the bacterium responsible for leprosy, is slowed by leprostatic agents. Leprostatic agents can either actively kill the growing mycobacteria or they can inhibit bacterial growth, each with their own unique mechanism of action.

8. Glycylcyclines

Antibiotics in the glycocycline family prevent bacterial growth by interfering with the process of protein synthesis. They are effective against tetracycline-resistant bacteria as well as sensitive gram-negative and gram-positive bacteria. Antibiotics in the glycylcycline family are effective against bacteria that have developed resistance to other drugs. This includes MRSA, VRE, and Pseudomonas aeruginosa, to name a few.

9. Glycopeptide antibiotics

Antibiotics belonging to the glycopeptide class prevent peptidoglycan production, hence preventing the development of bacterial cell walls. Infections caused by bacteria that are resistant to beta-lactams and other antibiotics, such as multi-resistant Staphylococcus aureus (MRSA) and enterococcal infections, can be treated with these drugs. As an added benefit, they can be utilized when a patient has an allergy to beta-lactams.

10. Cephalosporins

Antibiotics belonging to the cephalosporin class are generated from the fungus Acremonium, formerly known as Cephalosporium. Similar to penicillins, cephalosporins are bactericidal (kill bacteria).

11. Carbapenems

Beta-lactam antibiotics like carbapenems are effective against a wide variety of gram-positive and gram-negative bacteria, both aerobic and anaerobic. In 1976, the first carbapenem, thienamycin, was found. Antibiotics such as penicillin and cephalosporin are significantly weakened by the presence of beta-lactamase enzymes, often known as penicillinase. Carbapenems are famous for their ability to block these enzymes.

12. Antiviral Agents

Disease-causing viruses can be stopped in their tracks with the use of antiviral drugs. The window of time in which most antiviral drugs are effective is narrow, as viruses are often only active during replication. Since viruses share most of the metabolic processes of the host cell, finding treatments that are selective for the virus is challenging. Antiviral medications could be directed at viruses by targeting their unique enzymes.

13. Antituberculosis Agents

Chemotherapy for tuberculosis typically includes administering multiple medicines at once. Distinct drug classes inhibit the development of drug-resistant strains of Mycobacterium because they target different aspects of the organism.

14. Linezolid

There is a new class of antibiotics called oxazolidinones, which includes linezolid. Indicated for the treatment of multidrug-resistant infections, it kills bacteria by blocking their ability to produce new proteins. Linezolid use during pregnancy has been reported in only one case study.

Anti Infective Drugs Uses & Side Effects

Anti Infective Drugs are normally administered orally. They can be injected or used topically by doctors to the infected area.

Anti Infective Drugs usually start acting within a few hours. For the best results, patients should take all of their prescribed medication as directed by their doctor.

It is more likely that the germs will develop resistance to future treatments if the drug is stopped before the whole course has been taken. The ones who make it through will have been exposed to the antibiotic and may develop resistance.

Even if your symptoms have subsided, it is still important to finish the full course of Anti Infective Drugs.

Instructions for proper dosing can be found in both the drug's accompanying booklet and your doctor's notes.

In order to make the most of Anti Infective Drugs, there are a few things people can do.

a. If you're taking metronidazole, don't drink alcohol.
b. If you're taking tetracyclines, it's best to avoid dairy items because they can interfere with the drug's absorption.
c. Consistent dosing occurs when medication is taken at the same time each day or at regular intervals throughout the day.

Side Effects:

1. Superinfections

Overuse of broad-spectrum antimicrobials can wipe out healthy bacteria. When normal flora bacteria are removed, opportunistic pathogens that were previously kept in check are free to penetrate tissues, causing an infection known as a superinfection.

2. Hypersensitivity Reactions

The vast majority of Anti Infective Drugs & Medicines are protein-bound, meaning they can be transported through the bloodstream and provoke antibody production in susceptible individuals.

3. Neurotoxicity

Certain antimicrobials, particularly those that tend to concentrate in certain organs or tissues, might cause damage to or interfere with the normal functioning of nerve tissue. Aminoglycoside antibiotics, for instance, have been linked to symptoms including wooziness, vertigo, and even hearing loss due to their tendency to accumulate in the eighth cranial nerve.

4. GI toxicity

A number of antimicrobials have toxic effects on the GIT lining, leading to gastrointestinal symptoms such nausea, vomiting, stomach pain, and diarrhea. Hepatitis and liver failure can be caused by the harmful effects that some medicines have on the liver.

5. Kidney Damage

Aminoglycosides and other drugs have a direct toxic effect on the kidney's delicate cells, leading to renal impairment or even failure.

Anti Infective Vs Antibiotic

Anti Infective

Something with the ability to combat infections, either by slowing their progress or eliminating them entirely. The word "anti-infective" is broad enough to include drugs that kill not just bacteria and viruses but also fungi, protozoa, and worms. The term "anti-infective agent" refers to a class of medications used to combat infectious microorganisms that have invaded the human body.

Antibiotic

Antibiotics are prescribed to patients who have been diagnosed with bacterial or fungal illnesses. When first discovered, antibiotics were substances made by one bacteria that selectively inhibited the growth of another.
