Brief Answer:
Coreg is immediately absorbed when orally administered explained below...

Detailed Answer:
Hi,

Thank you for writing to us.

Before I go for the final conclusions, I want to understand your situation better:
- you are taking coreg while have been diagnosed with Heart failure and COPD bronchitis. Coreg is the trade name for carvedilol which is beta-blocker used to treat heart failure and blood pressure as in your case.

Now, with expected blood levels, I believe you refer to blood pressure. Please take note that Coreg is immediately absorbed with a mean terminal elimination half-time of about 7 to 10 hours.

If taken with food, it can be slowly absorbed and prevent orthostatic hypotension.

- however, coreg is not used in people with severe COPD or chronic bronchitis unless it is extremely necessary.

Hope this answers your query. Let me know if you have further questions.

Brief Answer:
Agent of beta-1-selectivity:metoprolol, atenolol or betaxolol...

Detailed Answer:
Hi back,

The decision on the best alternative for coreg will be made based on the analysis of your current health problems and if the action of the betablocker is affecting positively or negatively the dyspnea attack related to COPD.

Usually, beta blockage may advsersely affect pulmonary function by counteracting the bronchodilationeffect produced by catecholamine stimulation of beta-2-receptors.

In cases of broncho-spastic diseases like COPD, better alternatives are considered agents of beta1-selectivity like metoprolol, atenolol or betaxolol. However, they are still used with caution.

Hope this answers your query.

Recent questions on  Orthostatic hypotension

doctor1 MD

I think I have orthostatic hypotension but I am not sure. When I stand up I get the normal dizziness but my vision also fades to black for a few seconds. Sometimes I get tunnel vision. I am a runner so I thought it could be having a runner s pulse, but no one on my team experiences vision loss or as much dizziness. I am not dehidrated either. Is there anything I can do to stop this? Or do I need to see a doctor?

I am 20 years old, and have Addison s Disease. Recently I have had rapid heart rate, orthostatic hypertension, petachie spots, fatigue, mood swings, pain in legs, head aches...etc What is most concerning is the high heart rate, it stays in the 80 s at the least at rest. And it is very difficult to get up after sitting, my heart starts racing and pumping harder. Here are some blood test results: at 12:27 PM WBC 4.0L RBC 4.92 Hemoglobin 16.4 Hematocrit 47.5 MCV 96.6 MCH 33.4 MCHC 34.6 RDW 12.1 Platelets 178 Neutrophuls 41.9 Lymphs 43.6 Monocytes 10.3 Eos 3.5 Basos 0.7 Neutrophils (Absolute) 1.70 Lymphs (Absolute) 1.7 Monocytes (absolute) 0.40 Eos (Absolute) 0.2 Baso (Absolute) 0.00 eGFR - unable to calculate due to inappropriate age/gender/creatinine value glucose 76 BUN 14 creatinine 0.9 sodium 138 potassiu, 4.5 chloride 102 carbon dioxide 28 calcium 9.7 protein 7.1 albumin 4.1 globulin 3.0 bilirubin 3.0 alkaline phosphatase 49 AST 13 vitamin b12 487 CT scan recently done with no tumor on adrenals, adrenals actually couldn t be seen due to my lack of fat they say. I take 0.1 fludrocortisone and 30mg hydrocortisone. Any advice would be greatly appreciated, thank you.

I have the feeling of numbness in my head along with a constant headache, nausea and sudden feelings of being on fire. The heat starts from my back to my chest and head. I don t have a fever. When sitting still I get a feeling like I m on a boat. Dizzy spells and shaky hands even though I ve had a meal and I usually need to eat something sweet to stop the dizziness.
