correct diagnosis, accurate use of drugs, according to epidemiology, clinical diagnosis, pathological diagnosis and laboratory diagnosis, identify pathogens, and select drugs in a targeted manner. the selected drugs should be safe, reliable, convenient and inexpensive. don't be conceited or unknown, or abuse drugs, especially antibiotics.
correct compatibility, synergistic use of familiar with the nature of drugs, drug use and master the usage, dosage, indications, contraindications, adverse reactions, correct compatibility, reasonable prescription of cooperative medication, increase the curative effect, avoid antagonism and neutralization, can play a multiplier effect. such as sulfa drugs, quinolones, adding synergist, can increase the efficacy, and the combination of tylosin and mycophenolate, monensin can produce antagonism.
syndrome differentiation and treatment, comprehensive treatment, after comprehensive diagnosis, identify the cause of disease, quickly take comprehensive treatment measures. on the one hand, the use of effective antibiotics, pathogens, antibiotics or antiviral drugs; on the other hand, to restore the body's physiological function and regulation, alleviate or eliminate some serious symptoms, such as antipyretic, analgesic, strong heart, rehydration etc..
according to the course of treatment, do not change frequently, and now most of the commercial products are antibiotics, antibiotics, synergist, slow-release agent and adjuvant therapy. the curative effect is exact. under normal circumstances, doubling the amount of the first dose, second times can be appropriate dosage, the symptoms are reduced when the amount of maintenance, after the disappearance of symptoms, the additional medication 1 days to 2 days, to consolidate the efficacy, medication time is generally 3 days to 5 days. when the medicine is prevented, 7 days to 10 days is a course of treatment, and the mixture is mixed and fed.
correct dosage, pay attention to methods, different routes of administration can affect the speed and amount of drug absorption, affecting the speed and strength of the efficacy. intravenous injection can act immediately; intramuscular injection is slower than intravenous injection. we should take into account the body factors, drug factors, pathological factors and environmental factors in selecting different ways of administration. such as oral administration, the efficacy is susceptible to gastrointestinal tract content, the drug is generally before feeding, and more irritating drugs should be fed after feeding. intolerance of acid and alkali, easily damaged by digestive enzymes, should not be taken orally. systemic infection, injection of good, intestinal infection, oral medication.
the correct calculation of drug dosage, first see the weight of the drug, capacity unit, do not confuse. second, note the conversion between the international unit of medicine (iu) and the milligram (mg). most antibiotics are 1 milligrams, equal to 1000 units. third, pay attention to the conversion of the drug concentration, expressed as a percentage, purity percentage, refers to the proportion of weight, the percentage of solution refers to 100 ml solution containing solute grams.
