Lactose is the most important carbohydrate in the milk of most species. Its biosynthesis takes place in the mammary gland. The molecular structures of α- and β -lactose differ in the orientation of a hydrogen- and a hydroxyl group on carbon atom no.1 in the glucose moiety. Both forms change into one another continuously. At room temperature, the equilibrium results in a ratio of about 40% α-lactose and 60% β-lactose. The fact that two forms of lactose exist which differ in molecular structure has profound effects on various properties of lactose such as crystallization behavior, crystal morphology, solid-state properties, and solubility. The intestine does not actively absorb lactose unless it is split into its two-monosaccharide components, i.e. glucose and galactose. This hydrolysis of lactose is affected by the enzyme lactase, which is produced by the epithelium cells in the brush-border of the small intestine. Thus, the capacity of mammals to digest lactose is dependent on the lactase activity in the intestine. The maximum activity of the enzyme occurs shortly after birth and declines during the weaning period, after which it remains at a relatively constant level. Genetically determined factors governing residual lactase activity also exist. Individuals having low lactase activity are called lactose malabsorbers. Lactose intolerance is a condition in which people have symptoms due to the decreased ability to digest lactose. The principal symptom of lactose intolerance is an adverse reaction to products containing lactose (primarily milk), including abdominal bloating and cramps, flatulence, diarrhea, nausea, borborygmi, and vomiting (particularly in adolescents). These appear one-half to two hours after consumption.

Tocopherol (alpha tocopheryl nicotinate) is an ester of tocopherol and nicotinic acid. Vitamin E (Tocopherol) is sold commercially as the esterified form (alpha tocopheryl acetate, alpha tocopheryl succinate and alpha tocopheryl nicotinate). Alpha tocopheryl nicotinate has antioxidant and vasodilatory properties. It can be used as a mild warming agent, without producing the redness typical for nicotinic acid. Tocopherol (alpha tocopheryl nicotinate) has been available in Japan since 1967. Tocopherol under the brand name Juvela N is approved in Japan for the treatment of symptoms accompanying hypertension, hyperlipidemia, peripheral circulatory disturbance resulting from arteriosclerosis obliterans. Tocopherol has being shown to inhibit platelet aggregation.

Hesperidin is a flavanone glycoside found in citrus fruits. Its aglycone form is called hesperetin. Its name is derived from the word "hesperidium", for fruit produced by citrus trees. Hesperidin was first isolated in 1828 by French chemist Lebreton from the white inner layer of citrus peels (mesocarp, albedo). As a flavanone found in citrus fruits (such as oranges, lemons or pummelo fruits), hesperidin is under laboratory research for possible biological properties. One area of research is focused on the possible chemopreventive effects of hesperidin, but there is no current proof that hesperidin has this role in human cancer mechanisms. Hesperidin was effective in an animal model of Alzheimer's, alleviating pathological changes induced by aluminum. Early research suggests that taking one tablet of a specific product (Daflon 500, Les Laboratoires Servier) containing hesperidin and diosmin by mouth for 45 days decreases blood sugar levels and improves blood sugarcontrol in women with type 2 diabetes. For Rheumatoid arthritis (RA): early research suggests that drinking a beverage containing alpha-glucosyl hesperidin for 12 weeks improves symptoms of RA. Orally, hesperidin can cause gastrointestinal side effects, including abdominal pain, diarrhea, and gastritis. Headache can also occur in some patients. The possible anti-inflammatory action of hesperidin is probably due to the possible anti-inflammatory action of its aglycone hesperetin. Hesperetin appears to interfere with the metabolism of arachidonic acid as well as with histamine release. Hesperetin appears to inhibit phospholipase A2, lipoxygenase and cyclo-oxygenase. There is evidence that hesperetin inhibits histamine release from mast cells, which would account for the possible anti-allergic activity of hesperidin. The possible hypolipidemic effect of hesperidin is probably due to hesperetin's possible action in lipid lowering. Hesperetin may reduce plasma cholesterol levels by inhibition of 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase, as well as acyl coenzyme A: cholesterol acytransferase (ACAT). Inhibition of these enzymes by hesperetin has been demonstrated in rats fed a high cholesterol diet. The mechanism of hesperidin's possible vasoprotective action is unclear. Animal studies have shown that hesperidin decreases microvascular permeability. Hesperidin, itself or via hesperetin, may protect endothelial cells from hypoxia by stimulating certain mitochondrial enzymes, such as succinate dehydrogenase. The mechanism of hesperidin's possible anticarcinogenic action is also unclear. One explanation may be the inhibition of polyamine synthesis. Inhibition of lipoxygenase and cyclo-oxygenase is another possibility.

Homatropine (used in a form of bromide or methylbromide salts) is an analogue of atropine, which acts as an antagonist of muscarinic receptors. Homatropine was approved for the treatment of cough in combination with hydrocodone bitartrate.

Hyoscyamine as a natural plant alkaloid derivative and anticholinergic. Hyoscyamine is used to treat a variety of stomach/intestinal problems such as cramps and irritable bowel syndrome. It is also used to treat other conditions such as bladder and bowel control problems, cramping pain caused by kidney stones and gallstones, and Parkinson's disease. In addition, it is used to decrease side effects of certain medications (drugs used to treat myasthenia gravis) and insecticides. Hyoscyamine inhibits specifically the actions of acetylcholine on structures innervated by postganglionic cholinergic nerves and on smooth muscles that respond to acetylcholine but lack cholinergic innervation. These peripheral cholinergic receptors are present in the autonomic effector cells of the smooth muscle, cardiac muscle, the sinoatrial node, the atrioventricular node, and the exocrine glands. At therapeutic doses, it is completely devoid of any action on autonomic ganglia. Side effects include dry mouth and throat, increased appetite leading to weight gain, eye pain, blurred vision, restlessness, dizziness, arrhythmia, flushing, and faintness. Additive adverse effects resulting from cholinergic blockade may occur when hyoscyamine is administered concomitantly with other antimuscarinics, amantadine, haloperidol, phenothiazines, monoamine oxidase (MAO) inhibitors, tricyclic antidepressants or some antihistamines.

Cinchonine is cinchona bark alkaloid, which was used to treat malaria. Cinchonine is more efficient than quinine in increasing the intracellular accumulation and restoring the cytotoxicity of doxorubicin, mitoxantrone and vincristine on well-characterized multidrug resistance (MDR) cell lines. In the phase I of clinical trial was investigated the properties of cinchonine combined with the CHVP (cyclophosphamide, doxorubicin, vinblastine, methylprednisolone) regimen in relapsed and refractory lymphoproliferative syndromes.
