Protoveratrine A, the principal alkaloid of Veratrum album, has been used in the treatment of hypertension but has largely been replaced by drugs with fewer adverse effects.

Conditions:

Protoveratrine B is one of two alkaloids isolated from the plant Veratrum albumen. The main effect of both alkaloids is vasodilation in all vascular beds thereby reducing blood pressure. In the 1950's it was recognized that Protoveratrine B is the preferred compound which can be administered at significantly higher doses before the patient begins to vomit.
Pregnenolone sulfate is an endogenous neurosteroid with excitatory effects in the brain, acting as a potent negative allosteric modulator of the GABAA receptor, a positive allosteric modulator of the NMDA receptor, and activator of transient receptor potential cation channel TRPM1 and TRPM3. In the model of schizophrenia, treatment with pregnenolone sulfate normalized the hyperlocomotion and stereotypic bouts, and rescued the PPI deficits of dopamine transporter knockout mice. Promnesic properties of pregnenolone sulfate were demonstrated in rat models of spatial memory performance.

Cortisone is a hormone that is FDA approved for the treatment of primary and secondary adrenocortical deficiency, rheumatic disorders, psoriasis, exfoliative dermatitis, bronchial asthma, allergic conjunctivitis, hemolytic anemia, enteritis, tuberculosis, trichnosis. Cortisone acetate binds to the cytosolic glucocorticoid receptor. After binding the receptor, the newly formed receptor-ligand complex translocates itself into the cell nucleus, where it binds to many glucocorticoid response elements (GRE) in the promoter region of the target genes. The DNA bound receptor then interacts with basic transcription factors, causing the increase in expression of specific target genes. Common adverse reactions include convulsions, increased intracranial pressure with papilledema, vertigo, headache, psychic disturbances, hirsuitism, glaucoma, exophthalmos. Aminoglutethimide may lead to a loss of corticosteroid-induced adrenal suppression. Co-administration of corticosteroids and warfarin usually results in inhibition of response to warfarin, although there have been some conflicting reports. Cortisone is a natural steroid hormone. Its sulfate analog has been detected in in umbilical vein blood fetus plasma between 19 and 32 weeks of gestation with a significant increase at 29-30 weeks and in amniotic fluid. Base on the experiments with rats it was suggested that cortisone sulfate in mammals could be hydrolyzed enzymatically liberating sulfate ions from cortisone. Cortisone sulfate has been proposed for use as one of the glycosaminoglycan compound materials in a cartilage prosthesis and biological nasal bridge implant manufacture as well as auxiliary agent in powder aerosol composition for use in baby powder, dry shampoo, water-eczema remedy and antiperspirant.

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

Benzethonium chloride, also known as hyamine, is a synthetic quaternary ammonium salt. It has surfactant, antiseptic, and anti-infective properties and it is used as a topical antimicrobial agent in first aid antiseptics. It is also found in cosmetics and toiletries such as mouthwashes, anti-itch ointments, and antibacterial moist towelettes. Benzethonium chloride exhibits a broad spectrum of microbiocidal activity against bacteria, fungi, mold and viruses. The US Food and Drug Administration (FDA) specifies that the safe and effective concentrations for benzethonium chloride are 0.1-0.2% in first aid products. Aqueous solutions of benzethonium chloride are not absorbed through the skin. It is not approved in the US or Europe for use as a food additive. Being a quaternary ammonium salt, it is more toxic than negatively charged surfactants. However, in a two-year study on rats, there was no evidence of carcinogenic activity. Benzethonium chloride was characterized as a novel anticancer compound possessing both in vitro and in vivo efficacy justifying further investigation.
