A 1,4-dihydropyridine derivative of the formula ##STR1## wherein R.sup.1 and R.sup.2 are identical or different and each represents a hydrogen atom, a halogen atom or a nitro group, provided that R.sup.1 and R.sup.2 are not hydrogen atoms at the same time; R.sup.3 represents an alkyl group; R.sup.4 represents an aralkyl group which may be substituted; R.sup.5 and R.sup.7 are indentical or different and each represents an alkyl group; R.sup.6 represents a hydrogen atom or an alkyl group; R.sup.8 represents an alkyl group; R.sup.9 represents a hydrogen atom or an alkyl group; n and m are identical or different and each represents an integer of 0 to 6; provided that when either one of R.sup.1 and R.sup.2 is a hydrogen atom, R.sup.9 is an alkyl group; or an acid addition salt thereof. The 1,4-dihydropyridine derivative is characterized by a strong antihypertensive activity and the long duration of the activity.
Novel multibinding compounds are disclosed. The compounds of this invention comprise 2-10 ligands covalently connected, each of the ligands being capable of binding to a ligand binding site in a Ca

(EN) Calcium antagonists and compounds which lower intraocular pressure are combined in ophthalmic compositions to treat glaucoma. The calcium antagonists prevent or reduce the loss of visual field, while the intraocular pressure-lowering compounds maintain the intraocular pressure at normal levels.(FR) L'invention concerne des antagonistes du calcium et des composés abaissant la pression intraoculaire combinés dans des compositions ophtalmiques afin de traiter le glaucome. Les antagonistes du calcium empêchent au minimum la perte de champ visuel et les composés abaissant la pression intraoculaire maintiennent la pression intraoculaire à des niveaux normaux.

The instant disclosure describes methods for treating diseases and conditions of the central and peripheral nervous system by stimulating or increasing neurogenesis. The disclosure includes compositions and methods based on muscarinic receptor modulation, such as via inhibition of acetylcholine esterase (AChE) activity, alone or in combination with another neurogenic agent to stimulate or activate the formation of new nerve cells.
