Drug Mechanism of Action Clarithromycin
Mechanism of action. Clarithromycin prevents bacteria by acting as a protein synthesis inhibitor. It binds to 23S rRNA, a component of the 50S subunit of the bacterial ribosome, thus inhibiting the translation of peptides.

Macrolides: Mechanisms of Action and Resistance
Developed and produced by http://www.MechanismsinMedicine.com Animation Description: The DNA is shown as a circular double strand within the bacterial cell. Like the DNA of all living organisms, it contains the unique genetic code for all of the proteins required for bacterial survival. These include the proteins required for reproduction, growth, repair and regulation of metabolism. It also codes for the 3 kinds of RNA that are essential for carrying out protein synthesis. These are known as ribosomal RNA (rRNA), messenger RNA (mRNA) and transfer RNA (tRNA). In order for the bacteria to begin protein synthesis, the double-stranded DNA molecule must first unwind and separate in the region which codes for the specific protein that is to be made. Only one strand of the DNA serves as the template for this process known as transcription. Transcription results in the formation of messenger RNA (mRNA) which is a mirror copy of the DNA segment. Once the strand of mRNA is complete, it will detach from the DNA template and in turn become attached to ribosomes. Bacterial ribosomes are made of a small (30S) and a large (50S) subunit. After the 2 subunits join together around the strand of mRNA, synthesis of the polypeptide chain begins. This step involves the aligning of transfer RNA (tRNA) molecules in sequence along the mRNA. Each tRNA carries a unique amino acid (determined by the sequence of the tRNA) which, when aligned along the mRNA and ribosome, join together to form the polypeptide chain. This step is known as translation. The ribosome will continue to add amino acids to the growing polypeptide chain until it reaches a point along the mRNA that signals it to stop. At this point it releases the finished protein molecule. Macrolide antibiotics such as erythromycin, act as inhibitors of protein synthesis by attaching to the 50S ribosomal subunit. By so doing, they block the ability of the ribosome to synthesize the polypeptide chain. By inhibiting protein synthesis, macrolides are considered bacteriostatic antibiotics. However, at higher concentrations and with lower bacterial density or during rapid bacterial growth, macrolides may be bactericidal. Changes or modifications to the 50S ribosomal subunit (i.e. the target binding site for macrolide antibiotics) will confer resistance to macrolides and sometimes other classes of antibiotics. This type of resistance may be of a high level. This mechanism of resistance is mediated by the erm (erythromycin ribosome methlylation) gene which is found on plasmids or transposons (i.e. small genetic elements which are capable of moving from one bacterium to another and integrating into the host chromosomal DNA). Copies of the erm gene are transported to other bacteria via plasmids or transposons through "pili-like" channels. The erm gene is incorporated into the new bacterial genome. During the process of protein synthesis, this bacterium will transcribe and translate the genetic code of the erm gene resulting in the production of a protein enzyme capable of methylating the 50S ribosomal subunit at a specific position. This altered 50S subunit results in decreased binding affinity for macrolides and other antibiotics such as lincosamides (e.g. clindamycin) and streptogramin type B. This pattern of resistance is referred to as the MLS phenotype. Because the macrolide antibiotic is unable to bind to the 50S ribosomal subunit, it is unable to inhibit protein synthesis and thus the bacteria itself is not harmed, continuing to produce polypeptide chains of amino acids. A second mechanism of bacterial resistance to macrolide antibiotics is mediated by efflux pumps. These efflux pumps are encoded by the mef(A) gene which is a transposable element. Because they confer resistance to only macrolides and not lincosamides or streptogramin B they are referred to as the M phenotype. The efflux pumps are energy-dependent and for S. pneuomoniae result in moderate levels of resistance. These pumps traverse the cell membrane of the bacteria and function to "pump out" the macrolide antibiotic after it has entered the bacterium. It should be noted that for other bacteria such as Staphylococcus aureus for example, a different efflux system which is plasmid-mediated and encoded by the msr(A) gene results in macrolide resistance as well as lincosamide and streptogramin resistance in some cases. Despite the presence of these efflux pumps, macrolide antibiotics continue to enter the bacteria. However, once inside the cytoplasm of the bacteria, these efflux pumps actively remove the macrolide antibiotics before they have a chance to reach their target, the 50S ribosomal subunit and bacterial protein synthesis is unaffected.

Macrolides Antibiotics Animated presentation- Mechanism of action , Kinetics , Resistance
Macrolides are a class of antibiotics derived from Saccharopolyspora erythraea (originally called Streptomyces erythreus), a type of soil-borne bacteria. Macrolides inhibit protein synthesis in bacteria by reversibly binding to the P site of the 50S unit of the ribosome. Macrolides mainly affect gram-positive cocci and intracellular pathogens such as mycoplasma, chlamydia, and legionella. Erythromycin was the first macrolide discovered; other macrolides include azithromycin, clarithromycin, and roxithromycin. Their action is primarily bacteriostatic but may be bactericidal at high concentrations, or depending on the type of microorganism.

The Dangers of Antibiotics – Clarithromycin / Ciprofloxacin – How Antibiotics Destroyed My Life
In November 2014 and April 2015, I was severely impacted by two different sets of antibiotics. These antibiotics were Clarithromycin (Biaxin) and Ciprofloxacin (Ciprodex). I have made this video to share my story and to help others adversely affected by antibiotics. In the video I discuss my life prior to the antibiotics, the actual incidents, and my current state of affairs. I share things that have helped me along over the past 3 years and speak about potential better days ahead. Please help me spread the word about the dangers of antibiotics, particularly macrolide antibiotics such as Clarithromycin (Biaxin) and fluoroquinolone antibiotics such as Ciprofloxacin (Ciprodex). Too many unsuspecting people are being severely injured, permanently disabled or worse, killed, by these extremely potent antibiotics. It's time to send a message to pharmaceutical companies, doctors, pharmacists and regulatory agencies such as the Food and Drug Administration (FDA) and Health Canada, that poisoning the masses will no longer be tolerated in our society. ONE INJURY, DISABILITY OR DEATH AS A RESULT OF THESE ANTIBIOTICS IS ONE TOO MANY.

Кларитромицин  Опасен   Для Пациентов С Болезнями Сердца
Антибиотик Кларитромицин ширжоко используется при лечении отитов, синуситов, бронхитов, пневмонии, в лечении гастритов и язвенной болезни.Применение у больных с заболеваниями сердца, даже спустя годы после приема, может приводить к смерти. Healthcare providers should exercise caution when prescribing the macrolide antibiotic clarithromycin (Biaxin, generics) to patients with coronary heart disease because of a potential increased risk for heart problems or death that can occur years later, the US Food and Drug Administration (FDA) said today in a safety communication. The FDA's recommendation is based on 10-year follow-up results of the CLARICOR study, which found an "unexpected" increase in deaths among patients with coronary heart disease who received a 2-week course of clarithromycin that became apparent after patients had been followed for at least 1 year, the agency said.

Azithromycin is used to treat several bacterial infections and works by inhibiting bacterial protein synthesis, thus arresting bacterial growth. Azithromycin is prescribed for treating pneumonia, tonsillitis or pharyngitis, laryngitis, sinusitis, bronchitis, infections of the throat, skin and soft tissue infections, lyme disease, middle ear infections or otitis media, typhoid fever, traveler’s diarrhea and other intestinal infections. Do not take antacids within 2 hours either before or after taking azithromycin as antacids reduce the effectiveness of azithromycin. Please help us translate this video in your language to make it more universal and useful to your language community. We present useful and essential information on the drug azithromycin that everyone should know when taking this drug.
