Levobunolol is a non-cardioselective beta blocker, that is, it blocks beta-1 receptors as well as beta-2 receptors. The latter type dominates in the ciliary body, where it controls aqueous humour production. Blocking this type of receptor reduces aqueous humour production, lowering intraocular pressure.
The low concentration eye drops do not cause blood pressure changes and the changes with the higher dose drops do not last long. [48] The cardiovascular effects of phenylephrine may be potentiated in people with hypertension. [11] Hypertensive crisis with phenylephrine eye drops has been reported in people with hypertension. [11]
Timolol is a beta blocker medication used either by mouth or as eye drops. [3] [5] As eye drops it is used to treat increased pressure inside the eye such as in ocular hypertension and glaucoma. [3] By mouth it is used for high blood pressure, chest pain due to insufficient blood flow to the heart, to prevent further complications after a heart ...
Beta blockers' side effects include low blood pressure, reduced pulse rate, fatigue, shortness of breath, and in rare occasions, reduced libido and depression. Alpha agonists can cause burning or stinging, fatigue, headache, drowsiness, dry mouth and nose, and also they have a higher likelihood of allergic reaction. Carbonic anhydrase ...
Beta blockers vary in their lipophilicity (fat solubility) and in turn in their ability to cross the blood–brain barrier and exert effects in the central nervous system. [76] Beta blockers with greater blood–brain barrier permeability can have both neuropsychiatric therapeutic benefits and side effects, as well as adverse cognitive effects ...
Side effects of dipivefrine include local eye reactions among others. Dipivefrine is a prodrug of epinephrine (adrenaline) and hence acts as a non-selective adrenergic receptor agonist . [ 5 ] It is a substituted phenethylamine and catecholamine and is an ester of epinephrine with much greater fat solubility .
No formal interaction studies have been done with bimatoprost/timolol eye drops. As timolol (in tablet form) can be used to lower blood pressure and heart rhythm, it might add to the effect of other antihypertensive (pressure lowering) drugs. Also, drugs that block the liver enzyme CYP2D6 may increase the effects of timolol. [4]
Guaifenesin might act as an expectorant by increasing the volume and reducing the viscosity of secretions in the trachea and bronchi via stimulation of the gastric mucosa. . This stimulation leads to an increased parasympathetic activity in the respiratory tract via the so-called gastro-pulmonary reflex, although some in vitro studies suggested that it might also act directly on the ...
