Is it possible that succinylcholine drugs(nicotinic depolarizing neuromuscular blocker) decrease intraocular pressure?

Is it possible that succinylcholine drugs(nicotinic depolarizing neuromuscular blocker) decrease intraocular pressure?

No: Succinylcholine is known to increase intraocular minimally when given to secure the airway. The increase is small and passing, therefore it has been used in patients with increased intraocular pressure. ...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

Are beta blockers & calcium channel blockers truly contradicted in Wolff-Parkinson-White patients?

Are beta blockers & calcium channel blockers truly contradicted in Wolff-Parkinson-White patients?

Yes: In patients with wolff-parkinson-white especially those who have a history of atrial fibrillation or flutter, beta blockers and calcium channel blockers, which are av nodal blocking agents especially Diltiazem and verapamil, should be avoided. ...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

Do any beta blockers act on Central Nervous System? Labetalol, Propranalol? What about Alpha-1 blockers?

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

Examples of non-selective dopamine antagonist or a blocker ?

Thioridazine: Wow....you sound like one of my profs in training who would just love giving us the biggest pimp questions the next morning knowing that none of us were awake and none of us believed we'd get called to have to answer any of these really hard questions. The only one I can think of which is virtually entirely NON-selective is THIORIDAZINE. Everything else has some selectivity. ...Read more

Why might ACE inhibitors contribute to cardiac arrhythmia?

Why might ACE inhibitors contribute to cardiac arrhythmia?

ACE inhibitors: in general wouldn't contribute to arrhythmia so. In some situations could lower pressure and cause cathechol stimulus to arrhythmia. In others might cause electrolyte shift and be associated. Wouldn't be common ...Read more

How are calcium channel blockers and beta blockers different?

Blockers: The cell membranes have receptor sites(like plug outlets)for various drugs. The calcium blockers block the calcium channel plugs and the beta blockers block the beta receptor plugs. Each drug type has different effects but both lower blood pressure and have other effects. ...Read more

Why might epinephrine cause cardiac standstill in a patient on non-selective beta blockers?

Why might epinephrine cause cardiac standstill in a patient on non-selective beta blockers?

Theory: If you assume epi is alpha-beta stimulator and nonselective beta blocker blocks both types of beta, then pure alpha stimulation without beta stimulation to support it could theoretically cause the heart to crash. Not sure there is clinical evidence to support this however. ...Read more

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
