CYCLIZINE Uses, Side Effects, and More

CYCLIZINE

Brand name:- Not available, 


CYCLIZINE is an antihistamine and antiemetic drug used for the prevention and treatment of nausea, vomiting, and dizziness associated with motion sickness, and vertigo.

PHARMACODYANAMICS:-

Cyclizine is a piperazine-derivative antihistamine used as an antivertigo/antiemetic agent. Cyclizine is used in the prevention and treatment of nausea, vomiting, and dizziness associated with motion sickness. Additionally, it has been used in the management of vertigo in diseases affecting the vestibular apparatus. Although the mechanism by which cyclizine exerts its antiemetic and antivertigo effects has not been fully elucidated, its central anticholinergic properties are partially responsible. The drug depresses labyrinth excitability and vestibular stimulation, and it may affect the medullary chemoreceptor trigger zone. It also possesses anticholinergic, antihistaminic, central nervous system depressant, and local anesthetic effects.

 MECHANISM OF ACTION:- 

Vomiting (emesis) is essentially a protective mechanism for removing irritant or otherwise harmful substances from the upper GI tract. Emesis or vomiting is controlled by the vomiting centre in the medulla region of the brain, an important part of which is the chemotrigger zone (CTZ). The vomiting centre possesses neurons which are rich in muscarinic cholinergic and histamine containing synapses. These types of neurons are especially involved in transmission from the vestibular apparatus to the vomiting centre. Motion sickness principally involves overstimulation of these pathways due to various sensory stimuli. Hence the action of cyclizine which acts to block the histamine receptors in the vomiting centre and thus reduce activity along these pathways. Furthermore since cyclizine possesses anti-cholinergic properties as well, the muscarinic receptors are similarly blocked.


USED:- 

treatment of nausea, vomiting, and dizziness associated with motion sickness, and vertigo (dizziness caused by other medical problems).


SIDE EFFECTS:- 

dry mouth, nose and throat, blurred vision, tachycardia and urinary retention.


DOSE:-

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
