Droxidopa for Hypotension of Different Etiologies: Two Case Reports
P & T : a Peer-Reviewed Journal for Formulary Management
|March 5, 2019
Summary
Droxidopa, used for neurogenic orthostatic hypotension, was explored off-label for non-neurogenic causes. Case studies showed varied effects in diabetic autonomic neuropathy and rheumatoid arthritis-associated hypotension.
Area of Science:
- Pharmacology
- Cardiovascular Medicine
- Neurology
Background:
- Orthostatic hypotension (OH) involves a significant blood pressure drop upon standing.
- Droxidopa is approved for neurogenic OH but its efficacy in non-neurogenic OH is less understood.
- Primary autonomic failure, Parkinson disease, and other conditions are common causes of neurogenic OH.
Purpose of the Study:
- To investigate the off-label use of droxidopa in two patients with non-neurogenic orthostatic hypotension.
- To evaluate the treatment outcomes of droxidopa in diabetic autonomic neuropathy-associated OH and rheumatoid arthritis-associated autonomic dysfunction.
Main Methods:
- Case report of two patients receiving off-label droxidopa.
- Patient 1: Diabetic autonomic neuropathy-associated orthostatic hypotension.
- Patient 2: Hypotension due to autonomic dysfunction associated with rheumatoid arthritis.
Main Results:
- Outcomes varied between the two cases.
- Droxidopa demonstrated potential effects in treating non-neurogenic orthostatic hypotension, though not universally successful.
- Further research is needed to establish efficacy and safety in these off-label indications.
Conclusions:
- Droxidopa may offer therapeutic benefits in select cases of non-neurogenic orthostatic hypotension.
- The drug's efficacy can differ based on the underlying etiology of autonomic dysfunction.
- These cases contribute to understanding droxidopa's potential role beyond its approved indications.

01:24Data Reporting and Recording
5.4K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

02:11Reporter Genes
13.2K
Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.
