Clavulanic acid used, Side effects, Dose, & more

 Clavulanic acid

Brand name:- Agumentine, Amoxyclav, Clavam, Mahacef cv 625.

Clavulanic acid is a β- lactam drug that functions as a mechanism-based β -lactamase inhibitor. While not effective by itself as an antibiotic, when combined with penicillin-group antibiotics, it can overcome antibiotic resistance in bacteria that secrete β -lactamase, which otherwise inactivates most penicillins. It is mostly used with amoxycillin combination.
Amoxycillin + Clavulanic Acid is a combination of two medicines: amoxycillin and Clavulanic Acid. Amoxycillin is an antibiotic. It works by preventing the formation of the bacterial protective covering which is essential for the survival of bacteria. Clavulanic Acid is a beta- lactamase inhibitor which reduces resistance and enhances the activity of amoxycillin against bacteria.

Pharmacodynamic:-

Clavulanic acid inactivates some beta-lactamase enzymes that are produced by bacteria, therefore preventing enzymatic destruction of amoxicillin. This helps to treat a variety of bacterial infections which would otherwise be resistant to antibiotics without the addition of clavulanic acid.

 Pharmacokinetics:- 

Clavulanic acid has rapid oral absorption and a bioavailability of 60%; can also be injected. It's elimination t½ of 1 hour and tissue distribution matches amoxicillin, with which it is combined ( called coamoxiclav ). However, it is eliminated mainly by glomerular filtration and it's excretion is not affected by probenecid . Moreover, it is largely hydrolysed and decarboxylated before excretion, while amoxicillin is primarily excreted unchanged by tubular secretion.

Mechanism of action:- 


Clavulanic acid contains a beta-lactam ring in its structure that binds in an irreversible fashion to beta-lactamases, preventing them from inactivating certain beta-lactam antibiotics, with efficacy in treating susceptible gram-positive and gram-negative infections.

Used:- 

Used in the treatment of bacterial infections. It is indicated for short-term treatment of bacterial infections of respiratory tract, genito- urinary tract, skin, bone, and tooth among others.

Side effects:- 

Vomiting, Nausea, Diarrhea, Mucocutaneous candidiasis.

Dose:-  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
