Sumatriptan succinate is a synthetic drug belonging to a class of medications known as 5-hydroxytryptamine agonists (also called "triptans"), which is commonly used to treat cluster and migraine headaches with or without aura (warning signs occurring prior to the onset of a migraine). It is effective to relieve or eliminate the intensity of migraine and cluster headaches and accompanying symptoms including sensitivity to light or sound, nausea, and vomiting. However, it cannot help prevent future migraines/headaches or decrease the frequency of getting migraine and it is not recommended for other types of headache or for headache prevention.
It is believed that the pain of migraine headaches is induced by dilated blood vessels inside the head. Sumatriptan succinate relieves migraine headaches by affecting the serotonin in the brain, which results in constriction of blood vessels. Subcutaneous injection of this drug is more effective than other formulations.

Sumatriptan succinate is a highly selective 5HT1-like receptor agonist introduced as a
new treatment for migraine. It is indicated for the acute relief of migraine and cluster
headache. Oral administration is reported to be free of substantial side effects. The
compound appears to be a significant advance over the use of ergotamine and other
agents in the treatment of migraine.
Sumatriptan Succinate is a selective 5-HT1B/1D-receptor agonist with anticonvulsant properties (1,2). Sumatriptan Succinate is used for migraine relief (2).
Sumatriptan (succinate) is a serotonin 5-hydroxytryptamine 1 (5-HT1) receptor agonist with selective affinity for 5-HT1B and 5-HT1D receptors with IC50 values of 9.3 and 7.3 nM, respectively. It also has affinity for the 5-HT1F receptor (IC50 = 17.8 nM). Sumatriptan (succinate) has been shown to induce vasoconstriction of human middle meningeal arteries (EC50 = 89.9 nM) and reduce vascular inflammation associated with migraines.

ChEBI: A succinate salt obtained by reaction of sumatriptan with one equivalent of succinic acid. Selective agonist for a vascular 5-HT1 receptor subtype (probably a member of the 5-HT1D family). Used for the acute treatm
nt of migraine with or without aura in adults.
A solution of (phenylthio)acetaldehyde (6.05 g) in absolute ethanol (180 ml)
was added over 10 min to a solution of 4-hydrazino-Nmethylbenzenemethanesulphonamide
hydrochloride (10 g) in water (180 ml)
with cooling. After addition of the aldehyde was complete, the mixture was
stirred at 5°C for a period of 14 h. The precipitated solid was filtered off,
washed with water (200 ml), hexane (200 ml) and dried in vacuo to give the
N-methyl-4-[2-[2-(phenylthio)ethylidene]hydrazino]benzenemethanesulphonamide
(10.95 g), melting point 110°-112°C.
A solution of the N-methyl-4-[2-[2-
(phenylthio)ethylidene]hydrazino]benzenemethane-sulphonamide in absolute
ethanol (300 ml) was saturated with hydrogen chloride gas (ca. 30 min) whilst
being cooled in an ice-water bath, allowed to stir at room temperature for 3 h
and filtered. The filtrate was concentrated in vacuo and chromatographed to
afford a foam, which solidified on trituration with ether to an amorphous
powder (2.17 g). A sample was recrystallized from hexane-dichloromethane to
give the N-methyl-3-(phenylthio)-1H-indole-5-methanesulphonamide, melting
point 133°-134°C.
To a solution of N-methyl-3-(phenylthio)-1H-indole-5-methanesulphonamide
(460 mg) in absolute ethanol (50 ml) was added Raney nickel [4.6 g, 50%
slurry in water, washed to neutrality with deionized water (60 ml)] and the
reaction mixture refluxed for 16 h under an atmosphere of nitrogen. On cooling to room temperature, the supernatant was removed and the Raney
nickel extracted with ethanol (2x50 ml, which was brought to a gentle reflux
for 15 min under an atmosphere of nitrogen). The combined extracts were
filtered through a sand-celite pad and concentrated in vacuo. Chromatography
of the residue, afforded an oil (87 mg) which crystallized from ether-hexane
to give the N-methyl-1H-indole-5-methanesulphonamide (90 mg), melting
point 127°-129°C.
To N,N-diethyl chloroacetamide (800 mg) at 0°C was added phosphorous
oxychloride (250 μl) over a period of 30 sec. After the addition was complete,
the mixture was allowed to stir at 0°C for 15 min and then at room
temperature for 20 min. The N-methyl-1H-indole-5-methanesulphonamide
(300 mg) was added at 0°C and the mixture warmed to 65°C, whereupon it
dissolved. The mixture was stirred for 2 h at this temperature then poured
onto ice (ca. 5 g) and chloroform (5 ml) and stirred vigorously for 1 h. A solid
was filtered off, washed with water (50 ml), and hexane (100 ml) and dried in
vacuo to give the 3-(chloroacetyl)-N-methyl-1H-indole-5-
methanesulphonamide (192 mg).
A solution of the 3-(chloroacetyl)-N-methyl-1H-indole-5-
methanesulphonamide (160 mg) in ethanolic dimethylamine (30 ml, 33% w/v
solution in ethanol) was heated to reflux for 2 h. On cooling to room
temperature the solvent was removed in vacuo and the residue was
chromatographed to afford the 3-[(dimethylamino)acetyl]-N-methyl-1Hindole-
5-methanesulphonamide, melting point 230°C, dec.
To a suspension of the 3-[(dimethylamino)acetyl]-N-methyl-1H-indole-5-
methanesulphonamide (46.5 mg) in 1-propanol (5 ml) was added sodium
borohydride (62 mg). The reaction mixture was brought to reflux for a period
of 3 h, then an additional quantity of borohydride (60 mg) was added. After
refluxing for a further 1 h, the mixture was allowed to cool to room
temperature and quenched with 2 N HCl (10 ml). The aqueous solution was
washed with ethyl acetate (5 ml) then neutralized (NaHCO3 solution) and
extracted with ethyl acetate (3 x 15 ml). The combined extracts were
concentrated in vacuo and the residue chromatographed to give the 3-[2-
(dimethylamino)ethyl]-N-methyl 1H-indole-5-methanesulphonamide as a gum
(2 mg) which was shown by TLC.
Succinic acid in hot methanol was added to a hot solution of the the 3-[2-
(dimethylamino)ethyl]-N-methyl-1H-indole-5-methanesulphonamide in
absolute ethanol and the mixture was heated to reflux with stirring to give a
solution. The solution was allowed to cool with stirring to room temperature,
and the resultant suspension was farther cooled in an ice-bath for 2 h. The
solid was filtered off, washed with ethanol, and dried in vacuo to give the 3-
[2-(dimethylamino)ethyl]-N-methyl-1H-indole-5-methanesulphonamide, salt
with succinic acid (1:1).

Suprofen, a nonsteroidal anti-inflammatory agent, was introduced
in 1983 for use as an analgesic for the symptomatic relief of mild to moderate pain
and for primary dysmenorrhoea. By 1986 it had become evident that its use was
occasionally associated with flank pain sometimes accompanied by evidence of
decreased renal function. The Arthritis Advisory Committee of the United States
Food and Drug Administration met in December 1986 to review the situation and
decided against withdrawing suprofen from the market. However, in May 1987 the
Committee for Proprietary Medicinal Products of the European Community
recommended that all marketing authorizations should be suspended. The
manufacturer subsequently decided to suspend sale worldwide on the grounds
that sales had diminished to the point where the product was no longer
economically viable.
