BISHYDROXYCOUMARIN ( DICUMAROL) Uses, Side Effects, and More

 BISHYDROXYCOUMARIN ( DICUMAROL)


BRAND NAME:- DICOUMAROL 50mg tab.


BISHYDROXYCOUMARIN ( DICUMAROL ) is a naturally occurring anticoagulant drug that depletes stores of vitamin K (similar to warfarin, a drug that dicoumarol inspired) , and is slowly and unpredictably absorbed orally. Its metabolism is dose dependent — t½ is prolonged at higher doses. Has poor g.i. tolerance; not preferred now.



PHARMACODYNAMIC:-
Dicumarol is an coumarin-like compound found in sweet clover. It is used as an oral anticoagulant and acts by inhibiting the hepatic synthesis of vitamin K-dependent coagulation factors (prothrombin and factors VII, IX, and X).
 


MECHANISM OF ACTION:-

Like all 4-hydroxycoumarin drugs it is a competitive inhibitor of vitamin K epoxide reductase, an enzyme that recycles vitamin K, thus causing depletion of active vitamin K in blood. This prevents the formation of the active form of prothrombin and several other coagulant enzymes. These compounds are not antagonists of Vitamin K directly—as they are in pharmaceutical uses—but rather promote depletion of vitamin K in bodily tissues allowing vitamin K's mechanism of action as a potent medication for dicoumarol toxicity. The mechanism of action of Vitamin K along with the toxicity of dicoumarol are measured with the prothrombin time (PT) blood test. 


USED:- 
It is also used in biochemical experiments as an inhibitor of reductases. 
used as an oral anticoagulant and acts by inhibiting the hepatic synthesis of vitamin K-dependent coagulation factors (prothrombin and factors VII, IX, and X). Dicumarol inhibits vitamin K reductase, resulting in depletion of the reduced form of vitamin K (vitamin KH2). 


SIDE EFFECTS:-

•Unusual bleeding.
•A Change In Vision.
•Blurred Vision.
•Decreased Appetite.
•Gas.
•Hair Loss.

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
