Natural Angiotensin Receptor Blockers
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
Are these drugs used to reduce cardiac output: calcium channel blockers and beta (receptor) blockers?
Specific & limited: Pregnenolone is an adrenal hormone made from cholesterol, and is the pre-cursor for sex-steroid hormones. It is said to 'improve mood, ' but no strong data support. To my knowledge there is no role for it's use as a supplement. Aromatase inhibitors are for treatment of some breast cancers; they're also used off-label for ovulation induction in women. No other appropriate uses to my knowledge. ...Read more
Yes: There is a drug called Pegvisomant (somavert) that works by directly blocks the effects of growth hormone, and has been shown to improve symptoms of acromegaly. There are two other drugs that are less specific in binding but can also be used to treat acromegaly: bromocriptine and octreotide. These are highly specialized drugs that should be prescribed by a physician. ...Read moreSee 1 more doctor answer
Are beta blockers & calcium channel blockers truly contradicted in Wolff-Parkinson-White patients?
Names say it all: Angiotensin converting enzyme(ace) inhibitor vs angiotensin receptor blocker(arb). The names really say it all. Angiotensin which raises blood pressure needs to be activated to work. Aces prevent that activition. Arbs directly block the activity of angiotensin. Both have similar effects but there is more evidence for heart protection with aces than arbs but slightly more side effects with aces. ...Read more
Do selective adeno-adenergic blockers (prazosin, terazosin, doxazosin, trimazosin) protect from acute cocaine-induced vasoconstrictive damage?
Some: Cocaine causes it's effect by preventing the reuptake of monamine (epinephrine, etc) and causes these neurotransmitters to continue exciting the a1 receptor. The meds listed block alpha-1 receptors, so theoretically will blunt the effects of Cocaine on some vessels, but focus mostly (esp. Tamsulosin) on a specific sub-type (alpha-1a) that is mostly in the bladder, not in the vessels. ...Read moreSee 1 more doctor answer
Azd 6244- mek inhibitor- a selective mitogen-activated protein kinase (mek) inhibitor. Mk 2206- akt inhibitor. Why prescription for me? It ? Nsclc/mets
Molecular targeting: These agents are designed to selectively knock out key pathways your tumor may use to grow. Presumably you already had your tumor tested for these different mutations. Ask the doctor offering these options to explain their rationale. These are investigational studies and many of the treatment costs may be covered-ask. ...Read more
ACE-I: read this: http://circ.ahajournals.org/content/108/3/e16.fullGet a more detailed answer ›
Not safe: GABA antagonists are not routinely prescribed for GABA A receptor upregulation. The main one flumazenil (clonazepam) is used for overdoses from benzodiazepines in an ER setting. It may cause withdrawal seizures. Your best bet is to detox and enter a drug tx program for alcohol or sedative-hypnotic dependence issues. ...Read more
Do any beta blockers act on Central Nervous System? Labetalol, Propranalol? What about Alpha-1 blockers?
Yes, most of them: Beta blockers are either water soluble or lipid soluble. The latter cross the blood-brain barrier and act on the CNS (central nervous system). Atenelol and Naldolol are 2 water soluble ones that do not readily cross into the brain. Alpha blockers generally do act on the CNS, and the 2 most common side effects are hypotension and dizziness. ...Read more
Dear doc, is cod liver oil safe to take with:
1. bp meds (beta blockers, calcium channel blockers)
2. proton pump inhibitors &
3. VitD3 supplements?
Yes: It's fine to take with the blood pressure medications and the proton pump inhibitor. I would probably stop the vitamin D supplement as cod liver oil has vitamin A and D as the main vitamin sources. Vitamin D is one you can get in trouble with because it is fat soluble and can accumulate in your organs if you take too much. ...Read more
