Abstract
Background: A muscle relaxant is a drug which affects skeletal muscle function and decreases the muscle tone. It may be used to alleviate symptoms such as muscle spasm, pain and hyperreflexia. Skeletal muscle relaxants are heterogeneous group of medications that refer to 2 major therapeutic groups: neuromuscular blockers and spasmolytics. This study is carried out to evaluate the skeletal muscle property of Pheniramine maleate in Acetylcholine Induced Contractions on Isolated Frog Rectus Muscle.Methods: There are various screening techniques available to assess the muscle relaxant property of a drug. For initial screening, frog rectus muscle is used. Here frogs are divided into 4 different groups. Each group contains 6 isolated frog rectus muscles. The experiment is carried out by adding 100?g, 200?g, 400?g and 800?g of pheniramine maleate with 80?g of acetylcholine to the organ bath and response is recorded by kymograph.Results: Pheniramine maleate in various doses like 100?g, 200?g, 400?g and 800?g with 80?g of acetylcholine 100?g showed the maximum contractions of frog rectus muscle in kymograph. At all the doses of Pheniramine maleate, it showed a significant effect of skeletal muscle relaxant property.Conclusions: In conclusion with work done by using pheniramine maleate in different doses along with 80?g of acetylcholine. Pheniramine maleate showed the maximum skeletal muscle relaxant property on frog rectus muscle at 800?g dose.
