Dobutamine: IV medication given primarily for congestive heart failure from heart muscle weakening. This increases the ability of the heart to contract and increase blood flow throughout the body helping with heart failure symptoms. Used with diuretic therapy (Lasix) to get extra fluid/water out of the body. Used in hospital but can be used at home for chronic therapy for end-stage heart failure. ...Read moreSee 1 more doctor answer
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

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

This is not to be tried at home kids! if not severe and patient young/healthy, might only need close monitoring and IV fluids in icu. I hope this person is in a hospital! ...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

Variable: These medications are older antiarrythmics that have been around for decades and may suppress af. They must be used very cautiously and only by very experienced cardiologists, due to their potential to actually cause potentailly life threatening ventricular arrythmias in certain patients - called a pro-arrthymic effect..Newer medications have been shown to be both safer and more effective. ...Read moreSee 1 more doctor answer
There are a few uses: Benztropine is an anticholinergic drug used to reduce the side effects of antipsychotic treatment, such as pseudoparkinsonism and dystonia. It is also a second-line drug for the treatment of parkinson's disease. It improves tremor but not rigidity and bradykinesia. It is also sometimes used for dystonia, a rare disorder that causes abnormal muscle contraction. ...Read more
Are these drugs used to reduce cardiac output: calcium channel blockers and beta (receptor) blockers?
Better information: A stress echo allows you to view heart function under a stressor. The stress is an elevation in heart rate and produced by the dobutamine. It allows us to see if your blood flow in the coronary ateries can meet demand. Is like economics , supply vs demand. ...Read moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer

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 moreSee 1 more doctor answer
