Classification of vitamin-like compounds
Modern pharmacology identifies several key representatives of this group, each having a unique composition and structure:
- Vitamin $B_{15}$: pangamic acid, known as calcium pangamate.
- Vitamin $B_{13}$: orotic acid.
- Vitamin N: lipoic acid, represented in medical practice by the drug lipamide.
- Vitamin F: a complex of esters of valuable polyunsaturated fatty acids, including linoleic and linolenic acids.
Pharmacotherapeutic significance
The compounds in question are widely used in medical practice:
- They are prescribed primarily as part of combination therapy for various pathological conditions.
- In dermatological practice, elements such as vitamins H, N, and F are actively used to stimulate and enhance regenerative processes in the skin.
Herbal vitamin preparations
Herbal-derived agents exert a powerful pharmacological effect on the human body:
- They help boost the body's defense mechanisms.
- They exhibit adaptogenic effects, increasing endurance under extreme stress.
- They ensure the normalization and balancing of body system functions.
- They stimulate repair, accelerating the healing of wounds, ulcers, and fissures.
The main dosage forms here are rose hip preparations (fruit oil and syrup), sea buckthorn oil, as well as vitamin herbal mixtures, medicinal teas, and natural juices (e.g., carrot and cabbage juice).
Animal-derived preparations
This category of pharmacological agents represents specialized extracts from internal organs of animals or their metabolic products. The main and most well-known representatives include:
- Fish oil, which is obtained directly from cod liver.
- Liver preparations and extracts, such as vitagepat, hepavit, sirepar, compolon, and antianemin, used according to strict medical indications.
Briefly: answers to topical questions
What is the mechanism of the biochemical action of lipoic acid (vitamin N)?
Lipoic acid plays an essential coenzyme role in the oxidation and transfer of acyl groups within multicomponent enzyme systems. Its main function is direct participation in the oxidative decarboxylation of alpha-keto acids, such as pyruvic and alpha-ketoglutaric acids. In multienzyme pyruvate and alpha-ketoglutarate dehydrogenase complexes, it serves as a prosthetic group. The pharmacological mechanism of action of lipoic acid preparations involves improving the oxidation of carbohydrate metabolism metabolites and cellular energetics.
For which specific diseases is the administration of orotic acid (vitamin B13) indicated?
Orotic acid is used in medical practice as a growth promoter in premature infants and to enhance hematopoiesis processes in certain anemias. Its administration is also indicated to enhance regenerative processes in affected internal organs in such pathologies as myocardial infarction and muscular dystrophy.
By what criteria do vitamin-like compounds differ from true vitamins?
Vitamin-like compounds differ from true vitamins in their ability to be synthesized independently within the human body. At the same time, they are capable of forming functional coenzymes in the body, similarly to true vitamins.
To memorize vitamin-like substances, use the association: "Pangamate B15 and orotic B13, Lipoic N and F — fatty acids"
Class and exam questions
What are the main pharmacological effects of herbal vitamins?
