Benefits of the selective beta blocker toprol (metoprolol) for heart failure/ cardiomyopathy?

Benefits of the selective beta blocker toprol (metoprolol) for heart failure/ cardiomyopathy?

Reverses Ht Failure: Toprol xl (specifically that formulation, not metoprolol tartrate) and Carvedilol (generic or Coreg (carvedilol) brand name) have been shown in large, well controlled clinical trials to slow and sometimes reverse the damage of heart failure. They operate by blocking a malfunctioning feedback loop of hormones and signaling molecules, ultimately by blocking the effect of adrenaline on the heart. Good question! ...Read more

Pregnenolone and aromatase blocker uses?

Pregnenolone and aromatase blocker uses?

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

Do selective adeno-adenergic blockers (prazosin, terazosin, doxazosin, trimazosin) protect  from acute cocaine-induced vasoconstrictive damage?

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 more

Why is dobutamine given intravenously?

Why is dobutamine given intravenously?

No other form: Presently, there is no other form of Dobutamine on the market. Generally, when Dobutamine is used, one is seeking immediate action of the drug, if the drug was administered through just about any other route, it would take longer to act and the delay in action is not desirable. This of course excludes CHF patients on chronic Dobutamine pump, my first sentence is directed at them. ...Read more

83 yrs f; stable diastolic hf; rate controlled a-fib. Meds: cardizem, coumadin, (warfarin) lasix, inderal, spiriva (mild copd). Would a cardioselective betablocker be better than inderal ?

83 yrs f; stable diastolic hf; rate controlled a-fib.  Meds: cardizem, coumadin, (warfarin) lasix, inderal, spiriva (mild copd).  Would a cardioselective betablocker be better than inderal ?

Theoretically yes: In patients with COPD or asthma , cardioselective beta blockers like atenolol are felt to be superior to Inderal (propranolol) which also has possible harmful effects on the bronchial tree and could produce wheezing(bronchospasm). This may be a concern in someone like you who has copd. Your physician is best to advise you, however especially if you're doing well on inderal (propranolol). ...Read more

Can succinylcholine drugs (nicotinic depolarizing neuromuscular blocker) decrease intraocular pressure? Any answers appreciated!

Can succinylcholine drugs (nicotinic depolarizing neuromuscular blocker) decrease intraocular pressure? Any answers appreciated!

No.: Succinylcholine actually causes an increase in intraocular pressure for about 10 minutes after administration. Classic teaching was not to use succ in people with open globe injuries. There are situations, though, where using succ with other agents that lower IOP is preferred because it makes intubation more smooth, avoiding hypertension and airway reactivity that is worse for the situation anyway ...Read more
