Identify the name of the medicine | What? Ritodrine and Lijunza, are they "for men" and "for women"?

A few days ago, Yaowa asked a friend: "What diseases are Litojun and Lijunsha used to treat?" As a result, the friend humorously said to Yaowa: "Litojun is a man, and his name is Jun! Lijunsha is a woman, Miss Junsha! This character exists in the Pikachu animation." Haha! What a brain-opening idea!

Is your friend right? Do you want to know more about these two drugs? Today, let Yaowa take you to find out!

Litodun

Ritodrine is a pregnancy-preserving drug. As a commonly used drug in obstetrics and gynecology, it mainly acts on the uterine smooth muscle, inhibiting the contraction frequency and intensity of the uterine smooth muscle, effectively prolonging the pregnancy period, thereby preventing premature birth. It is often used to prevent premature birth after 20 weeks of pregnancy. So the "male" ritodrine in the mouth of friends is actually a drug for women (pregnant women)!

Ritodrine has two dosage forms: oral preparation and injection. In clinical practice, the injection form is generally used for intravenous drip first. After the therapeutic effect is achieved, the oral form is continued to maintain the therapeutic effect. However, it should be noted that ritodrine is a prescription drug. No matter which dosage form is used, it must be used under the guidance of a doctor. During the medication period, the pregnant woman's heart rate, blood pressure, pulse and fetal heart rate need to be checked regularly. If any adverse events and/or adverse reactions occur during the period, a doctor should be consulted. In addition, because ritodrine is a β2 receptor agonist, there may be potential drug interactions when used with antiarrhythmic drugs, antihypertensive drugs (possibly β2 receptor blockers), hormones, etc., so be sure to consult a doctor or pharmacist when using it.

Lijunsha

Lijunsa is actually a trade name, and the corresponding drug is erythromycin ethylsuccinate. I believe everyone must be familiar with the words erythromycin. That's right, erythromycin ethylsuccinate and erythromycin belong to the same large family, and both are antibacterial drugs. Erythromycin ethylsuccinate is the ethyl succinate ester of erythromycin, which is more stable than erythromycin in gastric acid and currently only has an oral dosage form. Clinically, it is used to treat acute tonsillitis, acute pharyngitis, sinusitis, tetanus, syphilis, Legionnaires' disease, whooping cough, etc. The dosage varies depending on the indication.

It should be noted that compared with other erythromycin preparations, erythromycin ethylsuccinate is more likely to cause hepatotoxicity, so liver function should be checked regularly during medication, and pregnant women are prohibited from using it. Since a considerable amount of erythromycin ethylsuccinate will enter breast milk after taking it, breastfeeding women should use it with caution or stop breastfeeding. In addition, it can also cause gastrointestinal reactions such as diarrhea, nausea, vomiting, and allergic reactions. When used in combination with other drugs, it may inhibit the metabolism of other drugs, affect the efficacy of the drugs, and even increase toxic reactions, so you should also consult a doctor or pharmacist when using it in combination.

Ritodrine is a tocolytic drug, while lijunza is an antibacterial drug. The two have very different effects, so don't confuse them!
