Vessels due to raynaud’s syndrome. what is raynaud’s syndrome is a condition where the blood flow to certain parts of the body is reduced why is it reduced due to narrowing of the arteries smaller arteries that supply blood to the skin are excessive due to this condition thereby limiting the blood supply to the affected area so the symptoms are fingers, toes, ears or the

Tip of the nose, numbness and coldness, yes this condition is also often accompanied by changes in skin color, so how this drug is used in pregnant women is both category c, so studies on experimental animals have shown side effects to fetus but not yet there are controlled studies in pregnant women so it is permissible to use it if the benefits outweigh the risks to the

Fetus. then, it was also stated that amlodipine can be absorbed into breast milk. so if you are breastfeeding, do not use this drug before consulting your doctor. now for the finished dosage form , amlodipine starts to work slower than nifedipine, while itself, there is amlodipine which is available in tablets of 5 milligrams and 10 mg. this can be consumed before and after

So that the duration of action becomes longer. if it’s given a slow release, the working period can be longer, while the fast-release tablet is the usual way to take it three times a day. well, there’s no medicine without side effects. in general, these side effects can be the same, yes, there is dizziness, headache due to dilated blood vessels, then due to blocking the

Entry of calcium ions while calcium is needed for contraction , one of them can inhibit contractions, it can cause constipation or difficulty defecating, then there is a feeling of warmth and heat in the face, neck or chest or also called flushing can cause stomach pain or nausea as well as unusual tiredness, what is unique about amlodipine can cause swelling in the legs

And then side effects that need to be considered from these calcium antagonist drugs, especially nifedipine, which has the effect of lowering pressure quickly, this can cause the risk of a fast or irregular heart rate, . then it can cause reflex tachycardia, heart rate increases, then the following interactions can occur if it is concurrent with anti-tb drugs or tb drugs

Or rifampin, then phenytoin, carbamazepine, the anticonvulsant, yes or phenobarbital, the effectiveness of nifedipine can be reduced. this drug , rifampicin, phenytoin, carbamazepine and phenobarbital, was then combined with drugs that can lower blood pressure, such as diuretics, ace inhibitors or together with the drugs erythromycin, ritonafir, ketoconazole, fluoxetine,

Cisapride, valproic acid, or diltiazem, which in general are drugs that inhibit can also interact with food so that with grapefruit there can be an effect of increasing levels and side effects of nifedipine so you should avoid grape fruit or grape fruit products while taking nifedipine. what about amlodipine? amlodipine itself levels and effectiveness can increase if used
