Prophylactic alkalization of the urine during cytostatic tumor treatment with the oxazaphosphorine derivatives, cyclophosphamide and ifosfamide

P BrühlW Vahlensieck


The so-called cystitis due to cyclophosphamide (Cytoxan) is caused by direct contact of the mucosa with alkylating metabolites in acid urine. These alkylating metabolites can be inactivated by instillation of cysteine into the urinary bladder. The cytostatically active metabolites of ifosfamide (Holoxan), a derivative of oxazaphosphorine, are eliminated by the kidneys as well. Their special toxicity is much higher than the toxicity of Cytoxan. The alkylating metabolites of ifosfamide cause urological complications essentially in supravesical areas (tubulopyelo-ureteritis). Some clinical trials demonstrate that increase of diuresis and alkalinization of urine by orally administered Uralyt-U are able to decrease concentration and aggressiveness of those metabolites.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.
