N-Methylacetamide is a flammable, difficult to ignite, hygroscopic, crystalline, colourless solid with a faint odor that is soluble in water. [1] Several isomeric forms are known. [8] [9] In solution, it is 97–100% present as the Z isomer with a polymeric structure. [10] [4] The compound has a high dielectric constant of 191.3 at 32 °C. [11]
Glanatec, the trade name of the approved formulation, takes the form of an eye drop solution of 0.4% ripasudil, equivalent to 4 g of ripasudil per 1000 mL of solution. The solution is developed, marketed, and distributed by Kowa Pharmaceuticals, but the compound itself was discovered by D. Western Therapeutics Institute, [ 2 ] a company who ...
Acetamide (systematic name: ethanamide) is an organic compound with the formula CH 3 CONH 2. It is an amide derived from ammonia and acetic acid. It finds some use as a plasticizer and as an industrial solvent. [5] The related compound N,N-dimethylacetamide (DMA) is more widely used, but it is not
The chemical reactions of dimethylacetamide are typical of N,N-disubstituted amides. Hydrolysis of the acyl-N bond occurs in the presence of acids: CH 3 CON(CH 3) 2 + H 2 O + HCl → CH 3 COOH + (CH 3) 2 NH 2 + Cl −. However, it is resistant to bases. For this reason DMA is a useful solvent for reactions involving strong bases such as sodium ...
Lifitegrast, sold under the brand name Xiidra (/ ˈ z aɪ d r ə / [2]), is a medication for the treatment of signs and symptoms of dry eye, a syndrome called keratoconjunctivitis sicca. Lifitegrast reduces inflammation by inhibiting inflammatory cell binding. [ 3 ]
Hydroxyamphetamine is used in eye drops to dilate the pupil (a process called mydriasis) so that the back of the eye can be examined. This is a diagnostic test for Horner's syndrome . Patients with Horner's syndrome exhibit anisocoria brought about by lesions on the nerves that connect to the nasociliary branch of the ophthalmic nerve . [ 7 ]
The most common side effect is conjunctival hyperaemia (increased bloodflow in the outer layer of the eye), which occurs in over 10% of people taking the drug. Side effects in less than 10% of people include other eye problems such as itching, foreign body sensation or dry eye, as headache or hyperpigmentation (darkening) of the skin around the eye.
Latanoprost, sold under the brand name Xalatan among others, is a medication used to treat increased pressure inside the eye (intraocular pressure). [5] This includes ocular hypertension and open-angle glaucoma. [5] Latanaprost is applied as eye drops to the eyes. [5] Onset of effects is usually within four hours, and they last for up to a day.
