Homatropine (Mandelyl tropine) .3
It is a synthetic alkaloid. It is prepared by passing hydrogen chloride
gas for 3-4 hours through a mixture of 7 parts of tropine, 10 parts of mandelic acid
and 2 parts of water. Homatropine is freely soluble in ether and chloroform.
Homatropine gives +ve reaction with Gerrard’s test giving red colour while with
Vitali’s test it gives yellow colour (instead of violet)
Homatropine resembles atropine and hyoscyamine in its general
physiological effects, but is much less toxic, and in small doses it exerts a hypnotic
effect. It has mydriatic effect like atropine but its action is more rapid, weaker, and
less prolonged than atropine.
Ipratropium (Isopropyl atopine) .4
It is a tropane alkaloid with quaternary nitrogen. It is used for treating
bronchial asthma and COPD.
Ipratropium .5
Atropine methobromide
It is used as antispasmodic.
Atropine methonitrate .6
It is used as antispasmodic.
Homatropine methyl bromide .7
It is used orally similar to atropine, i:e reduce over secretion & relief
gastroinestinal spasm.
Hyoscine (Scopolamine) .8
