What Is The Difference Between Selective And Nonselective Beta1 Blockers
One is more safe: Beta blockers can either block beta1 or beta2 receptors. Beta 1 receptors are in the heart and blocking them can cause the heart to slow down causing tiredness, irregular heart beat and shortness of breath....One of the drawbacks of timolol. Selective beta blockers such as betoptic (betaxolol) are supposed to have less of an effect of this type but are best avoided if a patient is sensitive to beta blockers. ...Read moreSee 1 more doctor answer
Systemic effects: Beta blocker drugs are effective agents to lower the internal eye pressure in treating glaucoma. There is some systemic absorption and in sensitive individuals non-selective blockers can lower the maximum heart rate, cause lung spasms and elevate the blood sugar. Selective blockers have less tendency to do these but if you are taking these agents, report changes to your ophthalmologist. ...Read more
Need advice on what is the the difference between selective and non selective beta blockers for glaucoma treatment?
.: Alpha blocker - dilate smooth muscle - in artery so decrease blood pressure. Also decrease action of norepinephrine (which normally increases blood pressure). Beta blocker - work on heart and decrease heart rate, and decrease action of Epinephrine (which normally increases blood pressure). Simplest answer i can write. ...Read moreSee 1 more doctor answer
Name says it all: Calcium channel blockers block the channel that allows vascular tone to increase and lowers blood pressure. The beta blockers work on beta recetors on the vessels to lower pressure . The heart has both beta receptors and calcium channels. Therefore betablockers and some calcium channel blockers can slow the heart rate as well. ...Read more
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

Antidepressants: SSRIs increase serotonin by inhibiting the re uptake of serotonin into the neurons. MAOIs increase serotonin by preventing the serotonin from being metabolized/destroyed. TCAs also inhibit the re uptake of serotonin but most also inhibit the re uptake of norepinephrine as well. They each have different side effects which can affect your ability to tolerate taking them. ...Read more
Differences: Both are in a class of medications called ace inhibitors primarily used for the treatment of high blood pressure. Neither is specifically "better" although Lisinopril tends to be slightly better in overall BP reduction. Side effects are similar with persistent cough in about 10% of patients. Both are generic medications. ...Read more
How they work.: Calcium channel blockers (ccb) affect calcium channels in the heart muscle cells. Beta blockers (bb) affect beta receptors in the conduction pathways of the heart. Each act to decrease heart rate and can also decrease blood pressure. Sometimes with ccb, the heart experiences an increase in heart rate when blood pressure decreases. There are different brands and kinds of both medications. ...Read moreSee 1 more doctor answer
Apples and oranges: Though both drugs are in the same class (beta blockers), their doses vary. Atenolol is available in 25, 50, and 100mg tablets. Metoprolol is available in 25, 50, 100mg "regular release" and 25, 50, 100 and 200mg "extended release". There are also differences in their specific sites of action. Apples and oranges. ...Read more
Similar but differen: Alpha and beta thalassemia are distinct and different disorders since they diminish the production of distinct and different globin polypeptide chains and particularly in the homozygous state that has distinct and different consequences. Alpha and Beta Thal minor are similar Alpha Thal major is not compatable with life and results in miscarriage. Beta Thal major requires prolonged treatments etc. ...Read more
What type of beta blocker is best to treat migraines-i.e selective or non-selective and which one?
BB vs ACE inhibitor: Atenolol is a generic beta blocker while coversyl is a brand name for generic perindopril which is an ace inhiibitor. They both lower blood pressure but by different methods. Beta blockers slow down heart rate while ace inhibitors work on via hormones, renin, angiotensin & aldosterone. ...Read more
None: Propranolol is Propranolol hydrochloride. All drugs are chemically salts (designated by the hydrochloride in the case of propranolol) but the second word is usually left out and the name is shortened to just "propranolol". This should not be confused with Propranolol hydrochlorothiazide which is a combination of 2 drugs: Propranolol + a diuretic. ...Read more
