Patients with coronary artery disease face increased risks when they undergo noncardiac surgery. This is attributable to the cardiovascular stress imposed by the surgical procedure and the effects of anesthetic agents on the cardiovascular system. Several approaches to managing patients with coronary artery disease before, during, and after noncardiac surgery include "prophylactic" myocardial r...

drug delivery via buccal mucosa by means of buccoadhesive formulations offer distinct advantages over peroral administration. recently, plant gums and exudates have been screened for their use as pharmaceutical adjuvants. the aim of this study is to evaluate matrix tablets containing plantago psyllium seed mucilage in addition to carbopol as a mucoadhesive agent, and propranolol hydrochloride a...

A central composite design was employed to produce microcapsules of propranolol hydrochloride by o/o emulsion solvent evaporation technique using a mixture of cellulose acetate butyrate as coat material and span-80 as an emulsifier. The effect of formulation variables namely levels of cellulose acetate butyrate (X(1)) and percentage of Span-80 (X(2)) on encapsulation efficiency (Y(1)), drug rel...

Aim: The objective of the present research work was to develop stable extended release (ER) pellets of propranolol hydrochloride, an antihypertensive drug, for which drug release profi le is compared with reference to the multiple conventional dosage form i.e. marketed product “Inderal LA” (160 mg). Method: ER formulations were developed using fl uid bed layering and coating techniques on sugar...

BACKGROUND This study is based on the hypothesis, that the toxic or physiological effects of an optical isomer may be counteracted or reversed by the administration of a potentized preparation of one of its stereoisomers. In the present study the enantiomer was used. METHODS 154 ICR conventional mice were used. 77 mice were administered (R)-(+)-propranolol HCl homeopathic potency prior to and...

While the pharmacological actions ofadrenergic beta receptor blocking agents specially those pertaining to cardiovascular system have been investigated in detail, there are only scattered reports dealing with their pulmonary vascular effects. Propranolol was shown to exert a variable effect on pulmonary arterial pressure and pulmonary vascular resistance (18). [4-( 2-isopropylamino-I-hydroxyeth...
