1. 0:01hi there and welcome back to
2. 0:03understanding medications in this
3. 0:06chapter we're going to be looking at one
4. 0:08of the specific types of opioids called
5. 0:10loperamide but before I get to the
6. 0:15specific actions of loperamide there's a
7. 0:18number of things that I'd like to talk
8. 0:19about the first of which has to do with
9. 0:22no minglature or the naming of something
10. 0:26and specifically I'll be talking of
11. 0:29course about the numing literature of
12. 0:31medications
13. 0:33if you know anything about loperamide
14. 0:36you may actually know it by one of its
15. 0:39many different names
16. 0:41and you may be wondering why is it that
17. 0:43Ken calls it loperamide instead of one
18. 0:46of those other names
19. 0:48and an example is right here this is the
20. 0:52actual chemical name of loperamide
21. 0:55nobody actually uses the chemical name
22. 0:58of loperamide except for the scientists
23. 1:01who are working in the laboratory and
24. 1:04they're trying to synthesize the
25. 1:06medication so just scratch that one off
26. 1:09your list but a lot of people remember
27. 1:12the brand names and one of the common
28. 1:14brand names of loperamide is imodium
29. 1:19but there can be literally hundreds of
30. 1:22brand names in the world for any drug
31. 1:25and each of those will have the generic
32. 1:28name on the label so you can see that
33. 1:31the generic name is the most important
34. 1:33one to remember
35. 1:35so what is the generic name the generic
36. 1:39name of a drug is the abbreviated
37. 1:41version of the chemical name and I'll be
38. 1:45showing you some examples of how we
39. 1:47achieve that generic name you may
40. 1:49eventually need to know at least a
41. 1:51couple of the brand names for any given
42. 1:54medication but in the first instance
43. 1:57it's always best to remember the generic
44. 2:00name
45. 2:05we just learned that the most
46. 2:08appropriate drug name to learn is the
47. 2:10generic name of medication and if you
48. 2:13have time possibly one of the most
49. 2:15frequently used brand names but the
50. 2:18generic name is the most important
51. 2:22the generic name is a shortened version
52. 2:25of the chemical name for instance the
53. 2:27generic name for this chemical structure
54. 2:30is metoprolol you'll never need to
55. 2:34remember the chemical name or exactly
56. 2:37how we got that to convert to the
57. 2:39generic name but I do want to stress one
58. 2:42important Point here and then come back
59. 2:45to that topic later with a lot more
60. 2:48information many drugs have a suffix
61. 2:51that will tell us a lot about the
62. 2:53medication for instance the suffix for
63. 2:56metoprolol is o l o l remember that the
64. 3:02way we got the o l o l was the
65. 3:082-0 portion of the chemical name so you
66. 3:12can see that any drug that has that
67. 3:15particular suffix has a portion of the
68. 3:18chemical structure that's the same
69. 3:20and if a portion of the chemical
70. 3:22structure is the same do you think that
71. 3:24maybe the drugs have similar actions
72. 3:29indeed in this case that tells you that
73. 3:31all o l o l drugs are from the drug
74. 3:35class known as beta blockers
75. 3:39and beta blockers slow down the heart
76. 3:42and therefore decrease the blood
77. 3:45pressure
78. 3:47every beta blocker slows down the heart
79. 3:50and decreases the blood pressure
80. 3:54so I've got a question for you you're
81. 3:56looking at a list of medications that a
82. 3:58client is taking
83. 4:00they are taking Propranolol prednisol
84. 4:03alone and lorazepam
85. 4:06pick one of the medications that this
86. 4:07person is on and very briefly describe
87. 4:10what it does
88. 4:13and although you've probably never seen
89. 4:15the drug Propranolol before you may have
90. 4:19noticed the o l o l suffix and that told
91. 4:23you that it was a beta blocker and that
92. 4:26decreases the heart rate and therefore
93. 4:28decreases the blood pressure
94. 4:31to be clear this is a practical session
95. 4:34that is aimed at teaching you how
96. 4:36important the suffix is to identify the
97. 4:38medication in reality you need to aim to
98. 4:42really understand each medication that
99. 4:44you learn but when you learn about the
100. 4:46beta blockers the O L O L drug class you
101. 4:50will understand five of the 200 most
102. 4:54widely prescribed medications
103. 4:56metoprolol Atenolol Propranolol
104. 5:00nabivilol and tylolol
105. 5:03and no one expected you to recognize the
106. 5:06other drug classes but just in case you
107. 5:08were curious Lorazepam is an
108. 5:11anti-anxiety anti-seizure medication
109. 5:13that's in the drug class called
110. 5:16benzodiazepines and you may know about
111. 5:19the benzodiazepines as being referred to
112. 5:21as benzos or as being related to Valium
113. 5:26and Xanax those drugs end in azepam or
114. 5:30azolam and when you learn about that
115. 5:33drug class you learn about five more of
116. 5:36the 200 most widely prescribed
117. 5:39medications
118. 5:40Alprazolam which is Xanax
119. 5:43clonazepam Lorazepam diazepam which is
120. 5:48Valium and Temazepam and finally
121. 5:51prednisone loan is a corticosteroid
122. 5:55corticosteroids are some of the most
123. 5:57important medications that we have to
124. 5:59decrease the immune system response but
125. 6:02they're plagued with side effects so
126. 6:04you'll really need to spend a long time
127. 6:05getting a clear picture of that drug
128. 6:08class
129. 6:09the other thing about corticosteroids is
130. 6:11that they have several different drug
131. 6:13roots and stems and not all of them are
132. 6:18suffixes not all of them are at the end
133. 6:21of the word some are prefixes and some
134. 6:25are just in the middle of the word to
135. 6:28quickly identify a corticosteroid that
136. 6:30you've never seen before look for the a
137. 6:33sewn pred or Court somewhere in the
138. 6:38generic name
139. 6:40fluticasone
140. 6:41methylprednisolone momentosone
141. 6:44prednisone
142. 6:46and hydrocortisone are all
143. 6:50corticosteroids and when you learn about
144. 6:52the corticosteroids you'll know quite a
145. 6:54bit about at least seven more of the 200
146. 6:59most prescribed medications
