Cetirizine Uses, Side Effects, and More

 Cetirizine Brand name:- Alerid,cetzine,zirtin,sizon 10mg tab 5mg/5ml syr.  Cetirizine is an antihistaminic medication. It treats allergy symptoms such as itching, swelling, and rashes by blocking the effects of a chemical messenger (histamine) in the body. Mechanism of action:- Cetirizine is a fast-acting, highly selective antagonist of the peripheral histamine H1 receptor. The H1-receptors inhibited by cetirizine are primarily on respiratory smooth muscle cells, vascular endothelial cells, immune cells, and the gastrointestinal tract. Unlike first-generation antihistamines such as diphenhydramine and doxylamine, cetirizine does not cross the blood-brain barrier to a large extent, avoiding the neurons of the central nervous system. As a result, cetirizine produces minimal sedation compared to many first-generation antihistamines. Given its antagonism with histamine H1-receptors, cetirizine effectively reverses many of the effects of histamine. Like other second-generation ant...

Chlorambucil Uses, Side Effects, and More

 Chlorambucil Brand name:- Leukeran 2,5 mg tab. Chlorambucil is a very slow acting alkylating agent, especially active on lymphoid tissue: Myeloid tissue is largely spared. It is the drug of choice for long- trem maintenance therapy for chronic lymphatic leukaemia; non - Hodgkin lymphoma and few solid tumors also resolve. It has some immunosuppressant property. Pharmacodynamic:-  Chlorambucil is an antineoplastic in the class of alkylating agents that is used to treat various forms of cancer. Alkylating agents are so named because of their ability to add alkyl groups to many electronegative groups under conditions present in cells. They stop tumor growth by cross-linking guanine bases in DNA double-helix strands - directly attacking DNA. This makes the strands unable to uncoil and separate. As this is necessary in DNA replication, the cells can no longer divide. In addition, these drugs add methyl or other alkyl groups onto molecules where they do not belong which in turn inhi...

Chloramphenicol Uses, Side Effects, and More

 Chloramphenicol Brand name:- Chloromycetin,Enteromycetin,Paraxin 250,500mg cap.  Chloramphenicol was initially obtained from streptomyces venezuelae in 1947 . It was soon synthesized chemically and the commercial product now is all synthetic. It is a yellowish white crystalline solid, aqueous solution is quite stable, stands boiling, but needs protection from light. The nitrobenzene moiety of chloramphenicol is probably responsible for the antibacterial activity as well as its intensely bitter taste. Mechanicsm of action:- Chloramphenicol inhibits bacterial protein synthesis by interfering with 'transfer' of the elongating peptide chain to the newly attached aminoacyl-tRNA at the ribosome- mRNA complex. It specifically attaches to the 50S ribosome near the acceptor (A) site and prevents peptide bond formation between the newly attached aminoacid and the nascent peptide chain without interfering with the aminoacyl-tRNA attachment to the 30S ribosome (the step blocked by tetrac...

Chlorhexidine Uses, Side Effects, and More

 Chlorhexidine Brand name:- Savlon or etc. A power, nonirritating,cationic antiseptic that disrupts bacterial cell membrane. A secondary action is denaturation of microbial proteins. It is relatively more active against gram - positive bacteria. Like hexachlorophene it persists on the skin.  Mechanics of action:-  At physiologic pH, chlorhexidine salts dissociate and release the positively charged chlorhexidine cation. The bactericidal effect is a result of the binding of this cationic molecule to negatively charged bacterial cell walls. At low concentrations of chlorhexidine, this results in a bacteriostatic effect; at high concentrations, membrane disruption results in cell death. Pharmacodynamic:-  Chlorhexidine is a broad-spectrum antimicrobial with demonstrated activity against both gram-positive and gram-negative bacteria, yeasts, and viruses.2 Antimicrobial activity is dose-dependent - chlorhexidine is bacteriostatic at lower concentrations (0.02%-0.06%) and b...
