چکیده

We studied the effects of nifedipine, a calcium antagonist, given intravenously and orally, on intraocular pressure in six normal volunteers. Nifedipine had no effect on intraocular pressure. Nifedipine is not contraindicated for the treatment of cardiovascular disease in glaucomatous patients and may have theoretical advantages in this situation, which are discussed.

Effect of Microencapsulation on Photo-Stability of Nifedipine

Nifedipine (NIF), a 1,4-dihydropyridine calcium channel antagonist, undergoes photo-degradation to dehydro-nifedipine (DNIF) upon exposure to ultraviolet (UV) light and to the nitroso analogue of dehydro-nifedipine (NDNIF) when exposed to sunlight or some kinds of artificial lights. NIF photo-degradation products do not contribute to clinical activity, thus prevention of photo-degradation of NI...

Calcium antagonists decrease adrenal and vascular responsiveness to angiotensin II in normal man.

1. The effect of the calcium antagonist nifedipine on the pressor and aldosterone responses to angiotensin II was studied in six normal subjects. 2. Blood pressure, pulse rate and plasma aldosterone, potassium and cortisol were measured during paired consecutive infusions of angiotensin II (5, 10 and 20 ng min-1 kg-1) on two separate occasions. Nifedipine (20 mg by mouth) was given, 30 min befo...

Effect of Calcium Channel Blockers on Intraocular Pressure in Rabbits

The objective of the study was to evaluate the antiglaucoma effect of calcium channel blockers diltiazem and verapamil. Albino rabbits were used and chronic glaucoma was induced in them using freshly prepared 150 units of alphachymotrypsin. 0.1 mL of drug solution was administered topically into the left eye whereas the right served as control. The pressure recording was carried out at 15, 30, ...

نقش نیفدیپین زیر زبانی در جلوگیری از افزایش فشار داخل چشمی ناشی از لوله‌گذاری تراشه

Background: The succinylcholine administration and tracheal intubation causes significant rise of intraocular pressure (I.O.P), which is of special concern in penetrating ophthalmic injuries. Different methods have been suggested to prevent this complication, but none of them were completely successful. Reports of use of calcium channel blocking agents specially nifedipine for prevention of I.O...
