Conditions:
Tetraethylammonium is an experimental drug with no approved indication or marketed formulation. Tetraethylammonium blocks of apamin-sensitive and insensitive Ca2(+)-activated K+ channels. It is a weak agonist of the nicotinic receptor. Tetraethylammonium produces transient reductions in blood pressure. Tetraethylammonium hydroxide is used as a soluble source of hydroxide ions and in the synthesis of ionic organic compounds.

Dienestrol (INN, USAN) (brand names Ortho Dienestrol, Dienoestrol, Dienoestrol Ortho, Sexadien, Denestrolin, Dienol, Dinovex, Follormon, Oestrodiene, Synestrol, numerous others) is a synthetic, non-steroidal estrogen. It is an estrogen receptor agonist. Estrogens work partly by increasing a normal clear discharge from the vagina and making the vulva and urethra healthy. Using or applying an estrogen relieves or lessens: dryness and soreness in the vagina, itching, redness, or soreness of the vulva. Conditions that are treated with vaginal estrogens include a genital skin condition (vulvar atrophy), inflammation of the vagina (atrophic vaginitis), and inflammation of the urethra (atrophic urethritis). Dienestrol currently discontinued in US, but still in market in some other counties

Sulfamethazine is a sulfonamide used to treat a variety of bacterial diseases in animals. It inhibits bacterial synthesis of dihydrofolic acid by competing with para-aminobenzoic acid (PABA) for binding to dihydropteroate synthetase (dihydrofolate synthetase).

Alverine is a smooth muscle relaxant used for the treatment irritable bowel syndrome. Alverine may increase calcium influx during action potentials due to inhibition of the inactivation of L-type calcium channels, but may also suppress evoked activity by inhibiting the sensitivity of contractile proteins to calcium.

Conditions:
Mephentermine, an amphetamine-derived phenethylamine, is an alpha 1 adrenergic receptor agonist and a hypertensive drug. Mephentermine is mainly used as a vasopressor agent with a sympathomimetic action, primarily causing release of noradrenaline and increasing cardiac output due to positive inotropic effect on the myocardium. The injectable preparation of mephentermine is commonly used for the short-term treatment of various hypotensive states such as shock or hypotension accompanying myocardial infarction or spinal anesthesia or surgical procedures like cesarean section. There is evidence on the fetal metabolic effect and placental transfer of mephentermine. However, a few studies have shown that mephentermine is as effective as phenylephrine in preventing maternal hypotension after spinal anesthesia and has similar effect on neonatal outcome. It is being widely used in developing countries like India as it is much more economical than phenylephrine and offers ease of use as it does not necessitate multiple dilutions as injectable. It is also available in India as 10 mg oral tablets. Despite it was thought earlier to have a little stimulant effect its abuse potential has increased, especially in sports due to its stimulant properties. Like amphetamines, it has shown to increase athletic performance in strength exercises and endurance in a dose of 14 mg/70 kg body weight. It has been proposed that phentermine, which is the main metabolite of mephentermine, acts by inhibiting monoaminoxidases A and B. Mephentermine adverse effects has been related to CNS simulation, excessive rises in blood pressure, and arrhythmias. Wyamine Sulfate (brand name of mephentermine sulfate) approved by FDA in 1951 was discontinued in USA.

SODIUM GLYCOLATE, a sodium salt of carboxymethyl ether, is used as a pharmaceutical grade dissolution excipient for solid dosage forms. It absorbs water rapidly, resulting in swelling which leads to the rapid disintegration of tablets and capsules. Without a disintegrant, these may not dissolve appropriately and may effect the amount of active ingredient absorbed, thereby decreasing effectiveness.
