What is used of Dalfopristin drug ?

 Dalfopristin 

Brand name:- Unkown 


Dalfopristin is an antibiotic used with quinupristin to treat severe or life-threatening infections of vancomycin-resistant Enterococcus faecium (VREF), and skin infections caused by methicillin susceptible staphylococcus aureus or streptococcus pyogenes.

Pharmacodynamic:- 

Dalfopristin is a streptogramin antibiotic, derived from pristinamycin IIA.

Mechanism of action:-

The site of action of dalfopristin is the bacterial ribosome. Dalfopristin has been shown to inhibit the early phase of protein synthesis.
Dalfopristin  bind to sites located on the 50S subunit of the ribosome. Initial dalfopristin binding results in a conformational change of the ribosome, allowing for increased binding by quinupristin. A stable drug-ribosome complex is created when the two drugs are used together. This complex inhibits protein synthesis through prevention of peptide-chain formation and blocking the extrusion of newly formed peptide chains. In many cases, this leads to bacterial cell death.

 Used:-

Used in the treatment of multiple sclerosis (MS). It helps to improve walking ability and walking speed in people with multiple sclerosis.

 Side effects:- 

Influenza, Viral infection, Anxiety, Vertigo, Palpitations, Breathlessness, Vomiting

Doses:- AS DIRECTED BY YOUR DOCTOR.

BASILIXIMAB Uses, Side Effects, and More

 BASILIXIMAB BRAND NAME:- Simulect   BASILIXIMAB is another anti CD - 25 antibody with higher affinity for the IL-2 receptor, but shorter plasma t½ (1 week) . is a monoclonal antibody used to prevent rejection in kidney transplants. It is a chimeric mouse-human monoclonal antibody to the α chain (CD25) of the IL-2 receptor of T cells. It is used in combination with other medicines used to prevent organ rejection. PHARMACODYNAMIC:- Basiliximab functions as an IL-2 receptor antagonist. Specifically it inhibits IL-2-mediated activation of lymphocytes, a critical pathway in the cellular immune response involved in allograft rejection.  MECHANISM OF ACTION:-  Basiliximab competes with IL-2 to bind to the alpha chain subunit of the IL2 receptor on the surface of the activated T lymphocytes and thus prevents the receptor from signaling. This prevents T cells from replicating and also from activating B cells, which are responsible for the production of antibodies, which would bind to the trans

Cefpodoxime proxetil Uses, Side Effects, and More

 Cefpodoxime proxetil Brand name:- cefoprox ,cepodem,DOXCEF 100,200mg cap.  Cefpodoxime Proxetil is an antibiotic. It kills the bacteria by preventing them from forming the bacterial protective covering (cell wall) which is needed for them to survive. Pharmacodynamic:-  Cefpodoxime is shown to be effective against most Gram positive and Gram negative bacteria, except Pseudomonas aeruginosa, Enterococcus, and Bacteroides fragilis. Mechanism of action:-  Cefpodoxime is active against a wide spectrum of Gram-positive and Gram-negative bacteria. Cefpodoxime is stable in the presence of beta-lactamase enzymes. As a result, many organisms resistant to penicillins and cephalosporins, due to their production of beta-lactamase, may be susceptible to cefpodoxime. Cefpodoxime is inactivated by certain extended spectrum beta-lactamases. The bactericidal activity of cefpodoxime results from its inhibition of cell wall synthesis. The active metabolite of cefpodoxime binds preferentially to penicilli

Know details about AMIKACIN DRUG ?

 AMIKACIN BRAND NAME:- AMICIN , MIKACIN, MIKAJECT 100mg ,250mg,500mg in 2ml inj. AMIKACIN it is a semisynthetic derivative of KANAMYCIN to which it resembles in pharmacokinetics,dose and toxicity. The outstanding feature of AMIKACIN is its resistance to bacterial aminoglycoside inactivating enzymes. Thus, it has to the widest spectrum of activity, including many organisms resistant to other aminoglycoside. However, relatively higher doses are needed for pseudomonas, Proteus and Staph. Infections.  The range of condition in which AMIKACIN can be used is the same as for gentamicin. It is recommended as a reserve drug for empirical treatment of hospital acquired gram-negative bacillary infections where gentamicin/tobramycin resistance is High. It is effective in  tuberculosis,but used only for multidrug resistant infection.More hearing loss than vestibular disturbances occurs in toxicity.  Pharmacodynamic:-  Amikacin is an aminoglycoside antibiotic. Aminoglycosides bind to the bacteria, c
