Transcript: This is the C2H2Cl2 Lewis structure. Carbon has 4 valence electrons, two Carbons; Hydrogen has 1 valence electron, but we have two Hydrogens; plus Chlorine, which is 7, and we have two Chlorines, for a total of 24 valence electrons.e have 24 valence electrons for the C2H2Cl2 Lewis structure. We'll put two electrons between atoms to form the chemical bonds, like this, so I've used 10. Then around the Chlorines, 12, 22, and then back to the central Carbons, 24.
US Brand Name. Descriptions. Alteplase is used to dissolve blood clots that have formed in the blood vessels. It is used immediately after symptoms of a heart attack occur to improve patient survival. It is also used after symptoms of a stroke and to treat blood clots in the lungs (pulmonary embolism) . Alteplase is used to dissolve blood clots in tubes (catheters) that are placed in large blood vessels (central venous access devices) . This medicine is available only with your doctor's prescription . This product is available in the following dosage forms:
Because it works on the clotting system, tPA (such as alteplase, reteplase, and tenecteplase) is used in clinical medicine to treat embolic or thrombotic stroke. Use is contraindicated in hemorrhagic stroke and head trauma. The antidote for tPA in case of toxicity is aminocaproic acid.t has been suggested that if tPA is effective in ischemic stroke, it must be administered as early as possible after the onset of stroke symptoms. Indeed, tPA has become widely considered standard of care in acute ischemic stroke, so long as the patient presents soon after the onset of stroke symptoms.
