Why do you have nosebleeds after taking nifedipine controlled-release tablets for a quarter? Is there any good way?

Nifedipine is the most common sustained-release tablet, and its function is to release slowly in the body. At first, because of the large dosage, the dissolution rate is faster, and the higher the blood concentration, the stronger the antihypertensive effect. With the passage of time, the release rate gradually slowed down and the antihypertensive effect gradually weakened. Nifedipine controlled-release tablets are drugs that are quantitatively released at a constant rate in vivo. At present, only Bayer Pharmaceutical Company of Germany can really reach this level. The trade name of nifedipine controlled-release tablets he produced is Baixintong, and the nifedipine sustained-release tablets (II) produced by Qingdao Guofeng Group Huanghai Pharmaceutical Co., Ltd. are produced according to the technology of controlled-release tablets. (They think that they produce controlled-release tablets, but the authoritative organization thinks that the quality can't reach the level of Baixintong), but it is a little better than ordinary sustained-release tablets, so it is called nifedipine sustained-release tablets (II) to distinguish it from ordinary sustained-release tablets. Their product name is nifedipine, which is the most common sustained-release tablet. Its function is to release slowly in the body.

In order to distinguish it from ordinary sustained-release tablets, it is called nifedipine sustained-release tablets (Ⅱ), and the product name is nifuda.
