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

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

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. ...Read more

Beta blocker side effect?

Beta blocker side effect?

Fatigue: Fatigue is the most common side effect, which may include daytime sleepiness. Erectile dysfunction may also occur. A beta- blocker also lowers heart rate and blood pressure, so if you are sensitive to it, or the dose is too large, bradycardia (low heart rate) or hypotension (low blood pressure) may occur. ...Read more

Can weight bering exercise change the pain receptor on the nervous system to a higher level, where you start of weak and then become strong?

Can weight bering exercise change the pain receptor on the nervous system to a higher level, where you start of weak and then become strong?

No, just its working: It's more likely that instead of altering your pain receptors, you're the exercises are actually making you stronger! Over time, weight-bearing exercises will become easier as your muscles get bigger and/or toned in response to the increased workload! Good for you! ...Read more

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

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

No: There are ARs found all over the body. It's a type of nuclear receptor, that is, it binds to T or DHT in the cytoplasm and then translocates into the nucleus. ARB's like casodex will block AR's wherever they are. Enzalutamide has a greater affinity, prevents translocation & binding to DNA. You may be talking about LHRH agonists or antagonist for prostate cancer. Firmagon (degarelix) blocks in the pituitary. ...Read more

What is the definition or description of: receptor?

What is the definition or description of: receptor?

Receptor Def: An organ, cell or molecule that accepts an outside signal and causes an internal change. Eyes receive light, touch receptors send messages to the brain when stimulated by pressure and estrogen receptors bind Estradiol causing responses of normal breast, ovary and uterus cells to rising and falling levels of the female steroid hormones. Most of the time "receptor" refers to one of the molecular typ. ...Read more

What does the complement receptor type 1 do?

What does the complement receptor type 1 do?

CR1: There is some controversy here, but it seems to mainly act through binding of C1q upon forming complexes with antibody in the bloodstream. CR1 is highly expressed on red blood cells, so these cells carry immune complexes away from the site of attachment to the spleen where the immune complexes are destroyed. An "immune complex" is a cluster of antibodies and there antigen targets (like a virus). ...Read more

What happens to the insulin receptors to make them insulin resistant?

Great question!: If you figure that one out, you will probably win the nobel prize in medicine. There are easily over 100 different defects in Insulin signaling (how Insulin talks to cells) which have been described in type 2 diabetic patients, ranging from mild to severe. That's one of the reasons why coming up with a cure for this disease is so difficult. ...Read more

Is there a way to bind to aptopsis inducing Fas receptor sites without activating the aptopsis process?

Is there a way to bind to aptopsis inducing Fas receptor sites without activating the aptopsis process?

Yes: Certain studies in cancer cells shows that binding of CD95 does not necessarily induce apoptosis; in one particular study it was also revealed that the extrinsic and intrinsic pathway may be linked, since Fas was found at the level of the mitochondria, but without activating of any caspases with engagement. ...Read more

There won't be any dopaminergic receptors as they are blocked by other drugs...is it not the correct answer??

There won't be any dopaminergic receptors as they are blocked by other drugs...is it not the correct answer??

Not necessarily: Drugs that block dopamine receptors do not do so 100%. We need dopamine in our system to function normallly. Dopamine blockers are given to people that have too much dopamine around to decrease the dopamine back to a normal level, not to get rid of it entirely. ...Read more

Are all Angitotension Receptor Blockers the same in terms of side effects? Is one more effective then the other? Which one has least side effects?

All the same: ARBs, as they are called, have the same side effects as a class and so if you are not tolerant of them, you would need to switch. None have unique side effects. Generally speaking, none is more effective than another in this class. The choice of which to use is often based on your doctor's familiarity and your health plan's formulary. ...Read more

Is GHB good at normal dosis and can I take it daily? Around 2 times max, so I won't get physically dependant for keeping my receptors occupied too much

No, and illegal: Ghb is a controlled substance used by prescription for a few rare conditions, and is more commonly known to the public as an illegal drug (one of the 'date rape' drugs, among other things). Unless prescribed for you by a physician for a particular diagnosis you should not use it at all. If caught with it you could be prosecuted. If prescribed, follow the doctor's instructions. ...Read more
