Schmidli J, Santillan GG, Saeed M et al. The effect of nimodipine, a calcium antagonist, on intracortical arterioles in the cat brain. Curr Ther Res. Blood Pressure: Nimodipine has the hemodynamic effects expected of a calcium channel blocker, although they are generally not marked. However, intravenous administration of the contents of Nimotop Capsules has resulted in serious adverse consequences including death, cardiac arrest, cardiovascular collapse, hypotension, and bradycardia. In patients with subarachnoid hemorrhage given Nimotop in clinical studies, about 5% were reported to have had lowering of the blood pressure and about 1% left the study because of this not all could be attributed to nimodipine. Nevertheless, blood pressure should be carefully monitored during treatment with Nimotop based on its known pharmacology and the known effects of calcium channel blockers.
What is the most important information I should know about nimodipine Nimotop? Because of the variable bioavailability of propranolol, the dose should be individualized based on response. Co-administration of chlorpromazine with propranolol resulted in a 70% increase in propranolol plasma level. Jeff Sessions R, Ala. Nimotop may cause dizziness or light-headedness. These effects may be worse if you take it with alcohol or certain medicines. Use Nimotop with caution.

Congestive heart failure CHF worsening of CHF, and pulmonary edema have occurred in some patients treated with a CCB, primarily verapamil. Some CCBs have also caused mild to moderate peripheral edema due to localized vasodilation of dependent arterioles and small blood vessels, which can be confused with the effects of increasing left ventricular dysfunction.

RAPID INJECTION OF Aminocaproic Acid Injection UNDILUTED INTO A VEIN IS NOT RECOMMENDED. Likewise, caution is advised in patients with acute myocardial infarction and pulmonary congestion documented by X-ray on admission, since associated heart failure may be acutely worsened by administration of a CCB. If propranolol therapy is interrupted and exacerbation of angina occurs, it usually is advisable to reinstitute propranolol therapy and take other measures appropriate for the management of angina pectoris. Since coronary artery disease may be unrecognized, it may be prudent to follow the above advice in patients considered at risk of having occult atherosclerotic heart disease who are given propranolol for other indications. The electrocardiogram, pulse, blood pressure, neurobehavioral status and intake and output balance must be monitored. Isoproterenol and aminophylline may be used for bronchospasm.

J Pharmacol Exp Ther. Propranolol therapy, particularly when given to infants and children, diabetic or not, has been associated with hypoglycemia, especially during fasting as in preparation for surgery. Hypoglycemia has been reported in patients taking propranolol after prolonged physical exertion and in patients with renal insufficiency. Blood levels of propranolol may be decreased by co-administration with inducers such as rifampin, ethanol, phenytoin, and phenobarbital. Cigarette smoking also induces hepatic metabolism and has been shown to increase up to 77% the clearance of propranolol, resulting in decreased plasma concentrations. generic caverta liquid

Nimodipine gel capsules are to be taken by mouth only. The medicine in the capsule should never be placed into a needle and syringe and injected into a vein. If the person taking nimodipine cannot swallow the capsule, use a needle to make a hole in each end of the capsule, and squeeze the medicine out into an oral syringe. The syringe can then be used to give the medicine through a nasogastric through the nose and into the stomach tube. Studies have reported a delayed absorption rate and a reduced half-life of propranolol in patients with renal failure of varying severity. Despite this shorter plasma half-life, propranolol peak plasma levels were 3 to 4 times higher and total plasma levels of metabolites were up to 3 times higher in these patients than in subjects with normal renal function.

Strubelt O, Diederich KW. Experimental investigations on the antidotal treatment of nifedipine overdosage. J Toxicol Clin Toxicol. There are no adequate and well controlled studies in pregnant women.
