a medicine that relieves pain (Prescott‚ 2000). Acetaminophen is created by synthesizing p-Aminophenol with Acetic anhydride. This reaction occurs when the amine group of the p-aminophenol is acetylated by the acetic anhydride. The resultant is an amide functional group (Ellis‚ 2002). However‚ the product that is obtained from this product is a crude solid which cannot be used as an analgesic and therefore the crude solid must be purified. This purified product is what is later put into the analgesic

modified using available therapies. Latanoprost is a F2-alpha prostaglandin analog designed to reduce the IOP in patients with glaucoma and ocular hypertension. Whereas‚ Bimatoprost is an ocular hypotensive drug that belongs to a family of fatty acid amides called prostamides. Its mechanism of action includes the reduction of tonographic resistance to aqueous humor outflow and an increase of the outflow rate through the uveoescleral pathway. When these 2 drugs are compared IOP reduction tended to be

CHEMISTRY 220 PRACTICAL REPORT PRACTICAL 1 Title: Nitration of Acetanilide Aim : To observe how an Aromatic electrophilic Substitution reaction takes place via the nitration of Acetanilide i.e. how hydrogen on a carbon chain is replaced with a nitro group. Reagents and Chemicals: • Acetanilide (5g) • Glacial acetic acid (5mL) • Concentrated sulphuric acid (10mL &1.5mL) • Concentrated Nitric acid (2.0mL) • Methanol (30-50mL) Modification to experimental

1.The patient was diagnosed with a Left knee arthroscopy with partial medial meniscectomy which simply means that there is torn cartilage in the left knee along with softening and/or breakdown of the tissue that lines the kneecap(platella).Post-op shows that during surgery the crescent shaped posterior horn that acts like a shock absorber was not able to be repaired. Also the tissues that aligns the kneecap remained at grade 2 if the grade increased it would make the condition worse. 2. IV of Fluids

acids. In acidic solution‚ nitrous acid converts aniline into a diazonium salt that is an intermediate in the preparation of a great number of dyes and other organic compounds of commercial interest. When aniline is heated with organic acids‚ it gives amides‚ called anilides‚ such as acetanilide from aniline and acetic anhydride. Acetic anhydride is a so called intermediate chemical within organic synthesis‚ which means a substance intended to create another substance. Acetic anhydride
