All drugs, depending on the pharmacological activity, are divided into three groups: poisonous, potent and non-potent. This separation is important to prevent the risk of overdose in the preparation of drugs and their use. In general, the concept of drug toxicity is relative. Many non-potent drugs can be poisonous in overdose.
Poisonous medicines (Venena) - these are means, the appointment, use, dosing and storage of which, due to high toxicity, must be done with extreme caution. These include drugs that cause addiction - narcotic drugs, approved by special authorities.
Powerful drugs (Heroica) - these are means, the appointment, use, dosing and storage of which must be done with caution.
The difference between poisonous and potent drugs is mostly only quantitative: toxic substances are usually used in doses of the order of thousandths and ten thousandths of a gram, and potent ones - in hundredths and tenths of a gram.
The belonging of a medicinal product to the list of potent or toxic substances is determined by the State Pharmacological Center for Medicines. The content of these lists varies depending on changes in the nomenclature of medicines. So, for example, in the GF X in the "Introductory part" there are lists of poisonous (list A) and potent (list B) substances. List B includes 326 names of medicines, list A - 116. By order of the Ministry of Health of Ukraine No. 233 dated July 25, 1997, six Lists of medicines registered in Ukraine were approved, including the Lists of potent, poisonous, narcotic and psychotropic drugs. paraty 1 .
1 The textbook gives the designation of potent and toxic substances, adopted according to GF X: list B and list A.
Storage, accounting and distribution of poisonous, narcotic and potent medicines in pharmacies is carried out in compliance with the rules established by orders of the Ministry of Health of Ukraine.Rules for the storage of poisonous and potent substances.
Poisonous medicines should be stored in isolation, in metal cabinets specially allocated for this purpose under lock and key. On the inside of the doors of the safe and cabinet there should be an inscription Venena indicating the list of stored substances, their single and daily doses.
Particularly toxic drugs - arsenic anhydride, crystalline sodium arsenate, strychnine nitrate, mercury dichloride (sublimate), mercury cyanide and oxycyanide - should be stored only in the inner lockable compartment of the safe.
In the cabinet for poisonous substances there should be hand scales, weights, weights, mortars, cylinders, funnels that are needed for the preparation of medicines. Such dishes are marked: “for atropine”, “for sublimate”, etc. These items are washed and processed separately from the rest of the dishes under the supervision of a pharmacist.
Strong medicines, as well as lapis pencils, should be stored in separate cabinets. On the inside of the doors there should be an inscription « Heroica» and a list of potent substances indicating the highest single and daily doses.
The inscriptions on the barbells in which poisonous medicinal substances are stored should be white on a black background, and on the barbells containing potent drugs - red on a white background, in both cases the highest single and daily doses should be indicated on the barbells . On standard medicines, the inscriptions are made in black on a white background.
During working hours, the pharmacist-technologist must have the key to the cabinet "for toxic substances" located in the assistant's room. Safes and cabinets are sealed or sealed after the end of the working day, and the keys to them, the seal or the ice cream must be kept by the head of the pharmacy or by persons authorized to do so by order of the pharmacy. Cabinets "for potent substances" after the end of the working day must be locked. Material rooms in which narcotic and especially poisonous medicines are stored must have light and sound alarms. The windows must have bars. After work is completed, these rooms are locked and sealed.
Rules for prescribing poisonous and potent substances. For prescribing narcotic drugs in pure form or mixed with indifferent substances (according to the list approved by the Ministry of Health of Ukraine), form f-3 is provided. Poisonous and potent substances, including ethyl alcohol, are written out on the F-1 prescription form.
Narcotic and stupefying drugs in pure form or with indifferent substances may be prescribed only to physicians who work in public health institutions.
The names of poisonous (the list of which is approved by the Ministry of Health of Ukraine) and narcotic drugs are written at the beginning of the prescription, then - all other drugs.
The prescription of form No. 3 is additionally signed by the head of the health care institution or his deputy for the medical unit and is certified by the seal of the health care institution (stamped). Prescriptions for dosage forms containing toxic substances and ethyl alcohol must be sealed with the seal of the medical institution "For prescriptions" and the personal seal of the doctor.
When prescribing poisonous or potent drugs in doses exceeding the highest single dose, the doctor must write the dose of this drug in words and put an exclamation mark.
Rules for dispensing medicinal products containing poisonous medicinal substances. When accepting a prescription for a drug containing a toxic substance, the pharmacist must be especially careful and accurate: it is necessary to clarify the age of the patient, check the correct dosing, the compatibility of the prescribed ingredients, and underline the name of the toxic agent with a red pencil. When preparing medicines, the toxic substance is weighed by a pharmacist-technologist in the presence of a pharmacist. The poisonous drug obtained by the pharmacist is immediately used to prepare the drug. It is forbidden to release poisonous, narcotic and potent drugs prescribed in the prescription that are not part of the prepared dosage form.
If a doctor prescribes a poisonous, narcotic or potent drug in a dose exceeding the highest single dose without an appropriate prescription, the pharmaceutical worker must dispense the prescribed drug in an amount of 50% of the dose established as the highest single dose.
Narcotic drugs prescribed on special prescription forms f-3 are dispensed only from a pharmacy attached for these purposes to territorial medical institutions.
Ethylmorphine hydrochloride, codeine, codeine phosphate, sodium etaminal, barbamyl mixed with other drugs are dispensed by pharmacies within the city or rural administrative district according to the prescriptions of medical institutions located on their territory.
When selling extemporaneously prepared drugs containing poisonous, narcotic substances and ethyl alcohol, patients are given a signature instead of a prescription (Fig. 5).
Prescriptions for dispensed medicines are stored in pharmacies, not taking into account the current year, for:
At five years old - for narcotic drugs prescribed on special prescription forms f-3;

One year - for drugs subject to quantitative accounting (with the exception of narcotic drugs), anabolic steroids;
At one month - on other preparations.
At the end of the storage period, all recipes are subject to destruction in the prescribed manner.
Prepared medicines containing poisonous substances are sealed by the person who checked the medicine (or sealed “for running in”).
Vials in which solutions of mercury dichloride (mercuric chloride), cyanide and oxycyanide are dispensed are labeled "Poison" with the image of crossed bones and a skull, "Handle with care", and the name of the poisonous drug in Russian (or local) language must also be indicated and the concentration of the solution.
A solution of mercury dichloride (sublimate) intended for disinfection is stained with eosin or fuchsin; the signature or label should indicate how the solution is tinted.
On the packaging of other drugs prepared in a pharmacy containing poisonous agents, as well as pure phenol, or solutions with a concentration above 5%, strong acids, perhydrol and other similar agents, the label "Handle with care" should be pasted.
All prepared medicinal products containing toxic substances are stored in a separate lockable cabinet until they are dispensed.
Poisonous medicinal substances (list A) are stored under lock and key in iron cabinets or in metal boxes (safe), which must contain the inscription “ Venena» (Poisonous).
And especially poisonous medicinal substances (morphine, atropine sulfate, etc.) are stored in the internal lockable compartments of safes and cabinets.
Typically, these substances in prescriptions are written in miles or centigrams. On the inside of the door of the safe or cabinet there should be a list of poisonous medicinal substances contained inside, indicating the highest single doses. Poisonous medicinal substances are subject to subject-quantitative accounting in special journals.
In the same cabinet (safe) there is everything necessary for weighing, measuring and mixing these substances (scales, weights, funnels, cylinders, measuring fingers, etc.). Styling design: black background, white letters.
In rooms where poisonous medicinal substances are stored, the windows are reinforced with iron bars, and the doors are upholstered with iron. With the permission of higher organizations, it is possible to store these substances in the same room with other medicinal substances. Cabinets and safes must be locked with keys, which are kept by the head of the pharmacy (responsible for the pharmacy), or by the pharmacist-technologist.

This is how the storage and work with toxic substances takes place, I hope you have stored the information written in this article in your memory. Next, we will touch on the potent medicinal substances of list B, do not miss it! Do not forget to rate articles and comment, Thank you for your attention!
The rules for the storage of poisonous, narcotic and potent medicines in pharmacy warehouses, medical institutions, control and analytical laboratories and other health care institutions are regulated by a special instruction approved by orders of the Ministry of Health.
Medicines of group A are divided into subgroups. Of the total number of drugs classified under the State Pharmacopoeia to list A, a certain part of the drugs is subject to subject-quantitative accounting in pharmacies. Salvarsan preparations are subject to special serial registration.
All narcotic, as well as highly toxic drugs: arsenic anhydride, crystalline sodium arsenate, strychnine nitrate, mercury dichloride (mercuric chloride) and mercury oxycyanide - should be stored in pharmacies only in safes, and especially toxic drugs - in the internal lockable compartment of the safe.
In pharmacies of categories V and VI, it is allowed to store narcotic and especially poisonous drugs only in a material room in safes or metal boxes screwed to the floor. It is not allowed to store these preparations in the assistant's rooms. In large pharmacies (categories I-IV), it is supposed to store in assistant rooms a supply of narcotic and poisonous drugs in quantities not exceeding a 5-day requirement, and storage should also be carried out in special safes.
The total stock of poisonous and narcotic drugs in city pharmacies should not exceed the monthly requirement. In other pharmacies, the stock of these drugs is determined by regional or regional pharmacy departments.
In duty pharmacies, poisonous and narcotic drugs are left overnight in a separate locked cabinet in the quantities and assortment necessary for the provision of urgent medical care. After duty, this cabinet is sealed.
All toxic drugs included in List A, but not related to narcotic and highly toxic drugs, are stored in isolation, in metal cabinets specially allocated for these purposes, under lock and key. In small pharmacies, all List A drugs (including narcotic and highly poisonous ones) can be stored in one safe.
Cabinets and safes containing poisonous and narcotic drugs are designed as follows:
1) on the inside of the doors of the safe and the cabinet, the inscription “A - Venena” (poison) is made;
2) below this inscription, on the same side of the door, there is a list of poisonous and narcotic drugs stored in a safe or cabinet, indicating the highest single and daily doses;
3) the inscriptions on the barbells, in which poisonous and narcotic drugs are stored, are made in Latin in white type on a black background (black label). Each barbell indicates the highest single and daily dose.
For the manufacture of drugs with toxic components in the safes and cabinets where they are stored, there must be hand scales, weights, mortars, cylinders and funnels. On the dishes used for the manufacture of medicines, it is desirable to be marked: “For sublimate”, “For silver nitrate”, etc. Washing of these dishes is carried out separately from the other under the supervision of a pharmacist.
The key to the cabinet with list A products, located in the assistant's room, must be with the pharmacist - pharmacy technologist during working hours. After the end of the working day, the cabinet is sealed and the key, together with the seal or ice cream, is transferred to the head of the pharmacy or another responsible pharmacy employee authorized to do so by the order of the pharmacy.
Material rooms, as well as safes in which narcotic and especially poisonous drugs are stored, must have light and sound alarms. Windows of material rooms where poisonous and narcotic drugs are stored should be equipped with metal bars. At night, these rooms are locked and sealed. Only the head of the pharmacy or a person authorized by him can issue narcotic and especially poisonous drugs from the material to the assistant for current work.
The storage of poisonous and narcotic drugs in pharmacy warehouses, in control and analytical laboratories, in pharmaceutical enterprises, in research and educational institutions is also carried out in safes or metal cabinets under lock and key, in rooms whose windows must have iron bars.
In cases where it is provided for by the instructions, the doors of the rooms in which poisonous and narcotic drugs are stored are covered with iron, and the room itself is equipped with light and sound alarms. Rooms where narcotic and poisonous substances are stored should be locked and sealed or sealed after work is completed. The keys, ice cream or seal must be kept by the person responsible for the storage of poisonous and narcotic drugs. In rooms, cabinets, safes where poisonous medicines are stored, it is necessary to have scales, weights, funnels, cylinders, mortars and other utensils for work.
In all cases, employees responsible for the storage and distribution of poisonous and narcotic drugs must strictly adhere to the relevant instructions and regulations approved by the Ministry of Health.
Subject-quantitative accounting of poisonous and narcotic medicines is carried out in a special book, numbered, laced and sealed with the signature of the head of a higher organization with a round seal.
In this book, one page is allocated for each name of the registered drug, on which the balances and receipts of this drug are reflected on a monthly basis, as well as its daily consumption.
The consumption of the drug is indicated for each day separately: dispensing according to outpatient prescriptions and dispensing to medical institutions, pharmacy departments and pharmacy points of group I. This is done so that at the end of the month, when checking the actual presence of toxic and potent substances and reconciling them with the book balance, the established norms of natural loss can be applied. These norms are applied separately: for outpatient dispensing of poisonous and potent substances and for dispensing to medical and other organizations.
Storage and accounting of salvarsan preparations. The list A group of drugs also includes salvarsan drugs - miarsenol and novarsenol. They are under the special control of the State Control Commission for the testing of such drugs under the Ministry of Health. This commission regulates the production of salvarsan preparations, establishes expiration dates, the procedure for their storage and accounting. Preparations are produced in sealed ampoules in a special package, on which the quantity, batch number and time of manufacture are indicated. In addition, on each package, the supplier indicates that the batch has passed chemical, biological and clinical testing, and the date of verification.
To record the movement of salvarsan preparations in pharmacies, a special journal is maintained. It contains information about the receipt and issuance of drugs in medical institutions. In the receipt part, the date of receipt of the drug at the pharmacy, the batch number, the dosage and the institution from which the drug was received are indicated. When issuing the drug, the journal indicates the name and address of the medical institution, date of issue, batch number, quantity and dosage.
Storage of potent drugs. A rather large group of drugs belongs to potent or, as they are commonly called, drugs of list B. These drugs should be stored in separate cabinets on the doors of which there is an inscription “B-Heroica” (potent) and a list of those included in list B
Preparations indicating the highest single and daily doses.
The inscriptions on the barbells, in which potent drugs are stored, are made in red on a white background. The barbells also indicate the highest single and daily doses. After work is completed, cabinets B are locked. During working hours they are open, they can be used by pharmacy workers involved in the manufacture of medicines.
Drugs that do not belong to lists A and B are stored in ordinary cabinets or on assistant turntables. The inscriptions on the barbells with these drugs are made in black on a white background.
In all cabinets where medicines are stored (List B or the usual list), a certain system for arranging barbells should be followed:
1) store liquid medicinal products separately from loose ones;
2) do not put medicines that are consonant in name next to each other, so as not to confuse them during the manufacture of the medicine. Therefore, it is impossible to arrange drugs on the shelves of cabinets in alphabetical order;
3) medicinal products for internal use that belong to list B should be placed in cabinets so that drugs with close higher doses are placed on the shelves (for example, drugs with doses of 0.1 g are stored on one shelf, and from 0.1 g on the other up to 0.5 git.d.), and place them on the shelves of cabinets, taking into account the pharmacological grouping.
As the experience of many pharmacies has shown, a single numbering of medicines brings significant benefits. For example, if shtangles and material cans with norsulfazol have No. 363, then under this number they are decorated in the assistant and material room. Thus, pharmacy workers clearly know that any barbell with this number contains norsulfazol.
