Question 1

is there a androgen receptor blocker that only bind to pituitary?

Accepted Answer

No: There is no androgen blocker that only binds at the pituitary.  The availabl eandrogen blockers will block androgen throughout the body, although in men the aromatase inhibitors (a homronal treatment for women) may have a differential effect on the pituitary and may increase testosterone in men.  
A good review of the pituitaryaxis and andorgens can be found here http://www.ncbi.nlm.nih.gov/pmc/ar

Question 2

which is the most potent histamine h1 receptor blocker that causes serious sedation?

Accepted Answer

Too many to list: There are truly dozens of h1 receptor blockers, many of the first generation of which will result in sleepiness. The tow most commonly used to treat insomina (which would result in sleeping) are Diphenhydramine and doxylamine.

Question 3

what's the most popular angiotensin receptor blocker and why is it the most prescribed? how do doctors decide which arb to prescribe?

Accepted Answer

: Most are very sensitive to drug pushers and that is the reason they are mostly forbidden to enter many dr offices. I would go to Drugs.com and review. The most popular may not be the best.  A lot of it depends on how well the company has put into pushing their own med.  I would also go to PUBMED.gov and read for yourself.

Question 4

when i take my angiotensin receptor blocker in the morning i get extreme anxiety, and when i take it at night it actually makes me sleepy. doesn't make sense. on drugs.com people complain about anxiety from arbs why is that?

Accepted Answer

: Medication adverse effects are common and vary individually. Sleepiness is not a common adverse effect of an ARB drug but the opposite, insomnia, is more common but I think it could happen. In that case, you can safely take this medication at bedtime. Unfortunately, I doubt if any doctor or pharmacist can offer you a satisfactory answer.

Question 5

what happens if someone with normal blood pressure of 120/80 takes an angiotensin receptor blocker daily, with an average reduction of 8 systolic/5 diastolic would it make them sick or damage their heart?

Accepted Answer

: A mild decrease in blood pressure should not cause any problems.  Possibly some lightheadedness or dizziness on standing.  It should not damage the heart.

Question 6

is it possible that when you give someone valsartan or any other angiotensin receptor blocker their sympathetic nervous system gets more activated and they become more hyper aroused in response to emotional stressors?

Accepted Answer

: Although measurement of sympathetic nervous system activity is difficult, hormonal studies have demonstrated that ARBs and ACE inhibitors have no significant effect on sympathetic nervous system activity.  I have worked with these converting enzyme inhibitors in numerous patients ever since they became available and have never seen inappropriate sympathetic nervous system overactivity in them.

Question 7

is stanozolol a beta receptor antagonist?

Accepted Answer

Stanozolol: Stanozolol is a synthetic anabolic steroid derived from testosterone.

It is banned from use in athletes but has a role in some medical conditions.

Please look up stanozolol in Wikipedia on the internet.

Question 8

which type of receptors do beta blockers affect?

Accepted Answer

Beta blockers: Beta blockers block beta adrenergic receptors

Question 9

what are the main beta receptors blocked by beta blockers?

Accepted Answer

Depends on drug: The receptors we are generally attempting to block with these medications are the beta-1 receptors in the heart. Medications such as metoprolol and atenolol work specifically on this receptor. There are also nonselective beta blockers such as labetalol, Propranolol and Carvedilol which work on this receptor as well as the beta-2 receptor. Carvedilol, in particular, also affects the alpha-1 recept.

Question 10

why does dobutamine act on beta 1 receptor on renal vessels?

Accepted Answer

All over the body: Because doputamine acts on beta receptors all over the body.  And Dobutamine is a partial vaso dilator, it decreases systemic vascular resistance, svr. It can mediate sympathetic nerve activity.
