Homatropine (Equipin, Isopto Homatropine) is an anticholinergic medication that is an antagonist at muscarinic acetylcholine receptors and thus the parasympathetic nervous system. It is used in eye drops as a cycloplegic (to temporarily paralyze accommodation ), and as a mydriatic (to dilate the pupil ).
Tropicamide, sold under the brand name Mydriacyl among others, is a medication used to dilate the pupil and help with examination of the eye. [ 3] Specifically it is used to help examine the back of the eye. [ 4] It is applied as eye drops. [ 3] Effects occur within 40 minutes and last for up to a day.
[1] [2] It contains hydrocodone, as the bitartrate, an opioid agonist; and homatropine, as the methylbromide, a muscarinic antagonist. [ 1 ] [ 2 ] It is taken by mouth . [ 1 ] [ 2 ]
Homatropine methylbromide ( INN; also known as methylhomatropine bromide) is a quaternary ammonium salt of methylhomatropine. It is a peripherally acting anticholinergic medication that inhibits muscarinic acetylcholine receptors and thus the parasympathetic nervous system. It does not cross the blood–brain barrier.
For symptomatic bradycardia, the usual dosage is 0.5 to 1 mg IV push; this may be repeated every 3 to 5 minutes, up to a total dose of 3 mg (maximum 0.04 mg/kg). [ 23 ] Atropine is also useful in treating second-degree heart block Mobitz type 1 (Wenckebach block) , and also third-degree heart block with a high Purkinje or AV-nodal escape rhythm .
Pholcodine is an opioid cough suppressant (antitussive). It helps suppress unproductive coughs and also has a mild sedative effect, but has little or no analgesic effects. It is also known as morpholinylethylmorphine and homocodeine. Pholcodine is found in certain cough lozenges, [ 2] and more commonly as an oral solution, typically 5 mg / 5 ml ...
Parasympathomimetic drug. A parasympathomimetic drug, sometimes called a cholinomimetic drug[ 1] or cholinergic receptor stimulating agent, [ 2] is a substance that stimulates the parasympathetic nervous system (PSNS). [ 3][ 2] These chemicals are also called cholinergic drugs because acetylcholine (ACh) is the neurotransmitter used by the PSNS ...
