Abstract

The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a sildenafil citrate chewable tablet and a preparation method thereof. The sildenafil citrate chewable tablet comprises sildenafil citrate, filler, excipient, sweetener, lubricant and compound flavoring agent. The present invention hides the taste of sildenafil citrate through repeated dry granulation; it can be taken without water, and the patient compliance is high; at the same time, it can effectively increase the storage stability of sildenafil citrate chewable tablets .

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a sildenafil citrate chewable tablet and a preparation method thereof. Background technique [0002] Sildenafil citrate is a drug for the treatment of male penile erectile dysfunction. Its main function is to dilate blood vessels, improve blood flow to target organs and reduce pulmonary hypertension. It is mainly used to improve male erectile dysfunction and to treat patients with pulmonary arterial hypertension. It is currently the drug of choice for clinical treatment of various types of erectile dysfunction. The recommended dose is 50mg, and the daily dose is 25-100mg. At the same time, sildenafil citrate has a slight effect of dilating the coronary arteries, so if patients with coronary heart disease also have male erectile dysfunction, it cannot be taken together with the drugs that expand the coronary arteries. This can lead to persistent hy...
