Cefixime Uses, Side Effects, and More

 Cefixime

Brand name:- Topcef, orfix 100,200mgtab/ cap, cefspan ,Taxim- o ,zifi tab.

Cefixime 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:-

Cefixime, an antibiotic, is a third-generation cephalosporin like ceftriaxone and cefotaxime. Cefixime is highly stable in the presence of beta-lactamase enzymes. As a result, many organisms resistant to penicillins and some cephalosporins due to the presence of beta-lactamases, may be susceptible to cefixime. The antibacterial effect of cefixime results from inhibition of mucopeptide synthesis in the bacterial cell wall.

 Mechanism of action:- 

The bactericidal action of Cefixime is due to the inhibition of cell wall synthesis. It binds to one of the penicillin binding proteins (PBPs) which inhibits the final transpeptidation step of the peptidoglycan synthesis in the bacterial cell wall, thus inhibiting biosynthesis and arresting cell wall assembly resulting in bacterial cell death.
Absorption Only 40–50% is absorbed from the GI tract (oral bioavailability). Absorption may be slowed but not decreased when taken with food. Average peak concentration after administration of oral suspension is approximately 25–50% greater than the peak concentration following oral tablet or capsules administration.
Distribution It has high concentrations in bile and urine. It can cross the placenta and its protein binding capacity is 65%.
It is always better to perform appropriate cultures and susceptibility studies to determine the causative organism and its sensitivity to cefixime


used:-

used to treat a number of bacterial infections.These infections include otitis media, strep throat, pneumonia, urinary tract infections, gonorrhea, and Lyme disease.For gonorrhea typically only one dose is required.


 Side effects:- 

Nausea, Diarrhea, Vomiting, Loose stools, Flatulence, Abdominal pain, Dyspepsia.

Dose:- 200-400mg BD, as directed by your doctor.

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

Cephalexin ( ZYD ) ( Cefalexin ) Uses, Side Effects, and More

 Cephalexin (ZYD) (Cefalexin) Brand name:-  Cephacillin 250,500mg cap; Sporidex, Alcephin,Cephaxin cap. Cephalexin (also called Cefalexin)  is the most common used orally effective first generation cephalosporin , similar in spectrum to cefazolin , but less active against penicillinase producing staphylococci and H. Influenza. Plasma protein binding is low; it attains High concentration in bile and is excreted unchanged in urine; t½ - 60min. Pharmacodynamic:-  Cephalexin (also called Cefalexin) is a first generation cephalosporin antibiotic. It is one of the most widely prescribed antibiotics, often used for the treatment of superficial infections that result as complications of minor wounds or lacerations.Label It is effective against most gram-positive bacteria through its inihibition of the cross linking reaction between N-acetyl muramicacid and N-acetylglucosamine in the cell wall, leading to cell lysis. Pharmacokinetics:- Cephalexin is rapidly and almost completely absorbed from t

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
