Urticaria, also called rubella, is an allergic disease of the skin and mucous membranes. The disease can develop throughout the year, but is more prevalent in the spring and summer months. The disease is usually treated with anti-allergy drugs (i.e. antihistamines, or histamine receptor antagonists). However, anti-allergy drugs have side effects such as drowsiness and drowsiness, and should not be taken by people engaged in high-altitude work, driving, operating precision instruments, or students attending classes. In recent years, some non-allergic drugs have been found to have a better effect on urticaria and do not have the side effects of anti-allergic drugs. Doxepin Some people use the drug 2 to 3 times a day, 25 mg each time (12.5 mg for children, 1 to 2 times a day) for the treatment of urticaria, and gradually reduce it to 12.5 mg to 25 mg once a day (or once every other day), or once every few days according to the condition, the results are all effective. It is also possible to powder the tablets and add them to snow cream for transdermal administration, which has the same efficacy and can avoid the destruction of the drug by gastrointestinal and liver. Dipyridamole Recent studies have found that this drug has antiviral effects. Some people use dipyridamole 100 mg, orally, 3 times a day, combined with vitamin C 100 mg, orally, 3 times a day, treatment of 50 cases of urticaria patients, the results of the cure rate of 82%, the total efficiency of 100%, acute urticaria cure time is generally 3 days, chronic urticaria for 3 to 45 days. Magnesium sulfate research has proved that magnesium ion can be activated through the activation of adenylate cyclase to make ATP (adenosine triphosphate) to generate cAMP (cyclic adenosine phosphate), so that some kinases in the cell phosphorylation and be activated, thus changing the cell membrane permeability, to prevent the release of allergy media, and thus can cure urticaria. Some people use 25% magnesium sulfate 10-20 ml added to 10% glucose solution 250-500 ml, to 1-2 ml / min speed intravenous drip, once a day, 1-10 days for a course of treatment, can effectively treat urticaria. Sodium chloride Some people use a high concentration of 38% sodium chloride solution to repeatedly scrub the affected area with a dosage of 3000-5000 ml for adults and 1000-1500 ml for children each time. A few moments after scrubbing, do not rush to rinse the white salt cream that appears on the skin surface, but cover it with a quilt to make it sweat, which can improve the efficacy. For those who have generalized itchy wind masses can prepare a solution for bathing, if the effect is not good in a short time, use salt powder to rub. 280 cases of patients quickly stop itching after 10-20 minutes of scrubbing, after 30 minutes most patients wind masses become lighter in red, after 1 hour 247 cases of wind masses do not protrude from the skin, after 3 hours 245 cases of patients basically disappear, after 1 day 260 patients hives all disappear, the rest all disappear within 2 days. The rest disappeared within 2 days, with a total efficiency of 98.2%. Some people treat urticaria with tretinoin tablets, 750 mg per time for adults, orally twice a day for 4 weeks as a course of treatment. In 60 cases, 38 cases were cured, 16 cases were effective and 6 cases were ineffective, with a total effective rate of 90%. Aminophylline Some people take 0.1 g of aminophylline tablets orally 3 times a day, and in some serious cases, 0.2 g of vitamin C orally 3 times a day and 20 ml of 10% calcium gluconate intravenously to treat 30 patients with urticaria, the results were cured in 2 to 15 days, with 100% efficiency, and chronic cases followed up for six months without recurrence. This method is particularly suitable for patients with urticaria associated with hypertension, bronchial asthma, cardiac asthma, coronary heart disease, angina pectoris.
