Cyclophosphamide Pharmacology
Cyclophosphamide
drug which converted to alkyl groups (aldophosphamide and phospharamide mustard) in the liver. These groups can cyclize in an aqueous environment to form a highly electrophilic "immonium ion" that can covalently bind to the N-7 nitrogen of guanine in DNA, which is a major site of action. Consequently it produce a cross linking of DNA when both alkyl groups react pairs of guanine residues in DNA. This breaks the DNA sequence, which results cell death. These agents can also react chemically with other cellular components containing nucleophilic group i.e. sulf hydryl, amino, hydroxyl, carboxyl and phosphate groups. Its action is cell cyclic and non specific. So it acts on the divided as well as resting cells. It has prominent immunosuppressant activity. .
Distribution - Widely distributed in the body.50% bound to the plasma proteins. It enters to the cerebrospinal fluid.
Metabolism - It is metabolized to its active forms i.e.aldophosphamide and phospharamide mustard in the liver. It is again metabolized to its inactive metabolites.
Excretion - Excreted via urine and foecus.15 to 30% is excreted as unchanged form.
