Metoprolol, sold under the brand name Lopressor among others, is a medication used to treat angina and a number of conditions involving an abnormally fast heart rate. [4] It is also used to prevent further heart problems after myocardial infarction and to prevent headaches in those with migraines . [ 4 ]
Atenolol is available in the form of 25, 50, and 100 mg oral tablets. [21] [4] It is also available in the form of oral tablets containing a combination of 50 or 100 mg atenolol and 50 mg chlortalidone. [21] Atenolol was previously available in a 0.5 mg/mL solution for injection as well, but this formulation was discontinued. [21]
Betaxolol also shows greater affinity for beta 1 receptors than metoprolol. In addition to its effect on the heart, betaxolol reduces the pressure within the eye (intraocular pressure). This effect is thought to be caused by reducing the production of the liquid (which is called the aqueous humor) within the eye. The precise mechanism of this ...
Cipralex brand escitalopram 10 mg package and tablet sheet. It is a reference escitalopram formulation, and was produced by Lundbeck. Escitalopram was developed in cooperation between Lundbeck and Forest Laboratories. Its development was initiated in 1997, and the resulting new drug application was submitted to the US FDA in March 2001.
Over the last 40 years, a variety of drugs have been developed from non-selective alpha-1 receptor antagonists to selective alpha-1 antagonists and alpha-1 receptor inverse agonists. [ 2 ] [ 3 ] The first drug that was used was a non-selective alpha blocker, named phenoxybenzamine and was used to treat BPH. [ 2 ]
Ebivol (Nebivolol) tablets. Nebivolol is a beta blocker used to treat high blood pressure and heart failure. [5] As with other β-blockers, it is generally a less preferred treatment for high blood pressure. [6] It may be used by itself or with other blood pressure medication. [6] It is taken by mouth. [6]
[50] Both enantiomers of propranolol have a local anesthetic (topical) effect, which is normally mediated by blockade of voltage-gated sodium channels . Studies have demonstrated propranolol's ability to block cardiac, neuronal, and skeletal voltage-gated sodium channels, accounting for its known membrane stabilizing effect and antiarrhythmic ...
However, there are short-term escape and long-term drift effects in some people. That is, tolerance develops. It may reduce the extent of the daytime IOP curve up to 50%. The IOP is higher during sleep. Efficacy of timolol in lowering IOP during the sleep period may be limited. [16] [17] [18] It is a 5–10× more potent beta blocker than ...
