Which is not an effect of atropine?: (A) Rise of body temperature, (B) Decreased salivary secretion, (C) Bradycardia, (D) Increased A-V conduction
Answer is C. ANSWER: (C) BradycardiaREF: KDT 4th Ed p. 94EFFECTS OF ATROPINE:CNS* Stimulates medullary , vasomotor and respiratory center* Depresses vestibular excitation , hence anti motion sickness* Suppresses cholinergic activity in basal ganglia, hence decreases tremor.* High doses may cause cortical excitation , restlessness , disorientation and hallucinationsCVS* Tachycardia* Abbreviates A-V refractory period* Facilitates A-V conduction* No consistent effect on BPEYE* Mydriaisis* Abolition of light reflexes* Cycloplegia* Rise of IOTSmooth musdes* All visceral smooth muscles are relaxed* Constipation* Bronchodilation* Urinary retention* Urinary bladder and ureter relaxation* Effect on uterus is minimal* Effect of biliary tract is less markedGlands* Decrease sweat, salivary , tracheobronchial and lachrymal secretions* Decreases secretion of acid and pepsinBody temperature* riseLocal anesthetic* effect present
