Absorption and Pharmacokinetics of Nitroglycerin to a New Formulation

Absorption and Pharmacokinetics of Nitroglycerin as a Tablet or in the Form of Rapidly Degradable Capsule in Young Healthy

The study evaluate the absorption rate of different sublingual formulation of nitroglycerine (NTG) either in the form of available tablets or a new rapid absorbable gelation capsule formulation "NTG1523" by determining T-max and area under the response curve of nitoglycerine in blood concentration as well as from clinical effects after intake. Data is entered on data sheet in anonymous form and processed. The results are presented in anonymous form by publication and lecture. Experts are given the supplement: "The applicant's rights in a biomedical research project

Ten healthy young volunteers are recruited,, and the experiments begin at 07:45 after an overneight fast. BMI and blod pressure are recorded and a catheter is inserted in an anticubical vein for blood samples. At 08.00 a sublingual tablet (Takeda, nitroglycerin 0.4 milligrams) tablet or a "NTG1523" capsule with 0.4 milligrams of nitroglycerine is placed under the tongue in random order. Subsequently, blood samples are taken every minute for 10 minutes, then every 10 minutes the following two hours. In addition, blood pressure and puls rate are measured every second minute the first ten minutes, and then every 10 minutes.Side effects and time to the participants registrate any effect of the drugs are assessed in a prefabricated scheme. The disadvantages associated with the experiment are sought monitored by adverse event registration which ends at the end of the trial. The trial day lasts 2 hours in which blood samples are taken as described above, and blood pressure and records are stored .

Nitroglycerine 0.4 milligram taken as ordinary tablets or "NTG1523" rapid absorbable capsule once in the morning, and subsequently blood samples and observations for 2 hours are performed

The study evaluate absorption rate of nitroglycerine 0.4 milligrams as tablets or a quickly absorbable capsuel "NTG1523" determined by T-max and area under the response curve in the blood of NTG as well as from clinical effects. Data is entered on data sheet in anonymous form and processed. The results are presented in anonymous form by publication and lecture.
