H2 Receptor Blocker Medication
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 moreSee 1 more doctor answer
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 ...Read more
I'm taking a new asthma medication described as specific to beta 2 receptors. What does this mean?
Beta-2 agonist: You are likely taking albuterol, or some form of it, which specifically targets the beta-2 receptors in the lungs for it's intended effects. These specific receptor medications are intended to treat disease of the lungs, without cross-reacting to beta-1 receptors in the heart. Hope this helps. ...Read moreSee 1 more doctor answer
Do psychiatric medications leave you more unhappy and unable to experience pleasure or happiness after they are discontinued? Deaden receptors, dopami
Do psychiatric medications keep on blocking or acting on receptors after they are discontinued. Are the same number of receptors freed up again ordead?
Not exactly: Vulnerable genes only produce dire effects when the environment triggers them. Psych medications can indeed have a persistent, sometimes permanent beneficial effect after long use (1 yr +) this is because the receptor changes alter signals into the nucleus and these change the proteins that regulate the genes. In effect, they restore gene functioning to "pre-trauma" baselines. ...Read moreSee 1 more doctor answer
My friend has been taking Adderall (dextroamphetamine and racemic amphetamine) 30mg a day for the past three months. Does this medication cause a permanent down regulation of dopamine receptors?
Drugs blocking: which receptor site? Need clarification before this can be answered. ...Read more
There wont be any dopaminergic receptors as they are blocked by other drugs...is it not the correct answer??
Acetylcholine: It is an agonist for both muscarinic an nicotinic receptors. ...Read more
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex. ...Read more
Not always: The body does not necessarily build a tolerance to all medications. Some are more prone to this than others, such as pain medications and benzodiazepines (ex xanax). Persons taking these medications long term will usually require more of the medication over time to get the same response. Most other medictaions do not result in building up tolerance. ...Read more

Can you tell me the four types of receptors that are blocked by the phenothiazine drugs for psychosis.?
Receptors: Chlorpromazine (the first phenothiazine antipsychotic) blocks more than 4 receptor types: d2, h1, m1, alpha1, alpha2, 5ht2a, and 5ht2c -- and a very small amount of 5ht1a. Other agents also block d2 receptors, but vary in histaminic, muscarinic, and serotonergic receptor effects. These differences relate to differences in side effect profiles. ...Read more

Are these drugs used to reduce cardiac output: calcium channel blockers and beta (receptor) blockers?
What happens if a certain poison/drug blocks the receptor site for a particular neurotransmitter, is it considered an agonist or an antagonist?
Could be either: We have both excitatory neurotransmitters (such as glutamate, glycine), and many inhibitory neurotransmitters (norepinephrine, acetylcholine, dopamine, serotonin), and some agents can interfere by imbalancing the homeostasis. However, mechanistically, receptor blockers really cannot be considered in either category. ...Read more
