Some antibiotics are available in the form of a lyophilizate( powder).They are intended for parenteral administration. The powder may be of a dark or light color, while in the first case this may indicate both inadequacy and suitability for the use of the preparation. When dissolved, some medicines form a cloudy suspension or release gas. The breeding of antibiotics is carried out to the extent indicated in the annotation. The instructions for use also contain information about the solution that is optimal for a particular medicine.
Calculation and dilution of antibiotics
Determination of the number of milliliters of the solvent for the drug is determined by dividing units or grams by 200 thousand( 0.2) or 100 thousand( 0.1), respectively. The 1: 1 dilution of antibiotics suggests that a milliliter of dissolved medicine contains 1/10 grams of the drug. So diluted drugs in vials containing 500 000 units( 1/2 gr.) And less. The breeding of antibiotics can be carried out in a different proportion. This method is used for drugs contained in a volume of 500,000 or more units. In these cases, the medicines are dissolved in a ratio of 1: 2.This means that in a milliliter of the dissolved mixture there are 200 thousand units( 0.2 grams) of the drug.
How is the breeding of antibiotics?
Before dissolving the drug, it is necessary to carefully read the annotation, the prescription of the doctor, and check the prescribed dose. You should also choose the place where dissolution will take place. A small table( or a section of the kitchen table) is covered with a clean napkin, where all the necessary things are put. It is necessary to prepare alcohol, cotton wool. Use lotions or colognes not recommended. From the vial of medicine, the foil is removed so that the center of the rubber plug opens. In case the solvent is contained in the ampoules, a special opening knife should be prepared( if necessary)( it is usually applied to the package).With a disposable syringe remove the packaging, the cap is removed from the needle undesirable. Next, you need to wash your hands with soap and wipe them with a solution of alcohol. Ampoules and a rubber stopper of a vial are also processed. After that, open the container with the solvent, draw the required amount into the syringe. Then the liquid is injected into the vial of the drug, the needle is pulled out, the resulting mixture is shaken. The powder must completely dissolve. After take another syringe and inject it into the vial with dissolved medication. The needle must be completely immersed in the preparation. The entire amount of the drug is collected, the place of injection is rubbed with alcohol. As a rule, antibiotics are injected deeply and slowly into the muscle.
Which solvent should I choose?
Usually, when prescribing a medicine, the specialist recommends which fluid to use. If there are no prescriptions from a doctor, you can consult a pharmacist when buying a medication. In addition, the annotation contains all the necessary information. Various solutions can be used for dilution, for example preparations "Lidocaine", "Novocaine" and others.
