ALLOW few pairs to respond and let other pairs to add on points not mentioned WRITE their response on the flip chart/board CLARIFY and SUMMARIZE by using the content below • Vitamins are organic compounds and a vital nutrients that organisms require in limited amounts • Vitamins and minerals listed in national essential medicine list include: vitamin A, vitamin B complex, vitamin C, vitamin D, vitamin E, vitamin K, calcium and selenium • Indications of Vitamins and Minerals: o Vitamin A, is used for prevention and treatment of ocular defects known as xerophthalmia it is also used as a supplement where diet is known to be inadequate. o Vitamin B complex, is composed of nicotinamide, thiamine and riboflavin. It is used in management of vitamin B complex deficiencies, isoniazid induced neuropathy and penicillin induced neuropathy o Vitamin C is used in prevention and treatment of scurvy o Vitamin D, the term Vitamin D is used for a range of compounds which possess the property of preventing or treating rickets o Vitamin E is indicated for some neuromuscular abnormalities o Vitamin K is used for prevention and treatment of vitamin K deficiency bleeding o Calcium gluconate used in the management of hyperphosphataemia o Selenium is used in management of selenium deficiency PST 04211 Basic Pharmacology NTA Level 4 Semester 2 Facilitator Guide 283 STEP 3: Contraindications of Vitamins and Minerals (20 minutes) Activity: Brainstorming (5 minutes) Ask students to brainstorm on the following question: • What are the Contraindications of Vitamins and Minerals? ALLOW few students to respond WRITE their responses on the flip chart/ board CLARIFY and SUMMARISE by using the content below • Contraindication of vitamin and mineral o Vitamin A, is not contra indicated to any specific group of individual o Vitamin B complex, is not contra indicated to any specific group of individual but should be given with caution because it may cause anaphylactic shock when given by injection o Vitamin C is not contra indicated to any specific group of individual o Vitamin D is contraindicated to people with hypercalcaemia, metastatic calcification o Vitamin E is not contra indicated to any specific group of individual neonate weighing less than 1.5 kg o Vitamin K neonates, infants and women in their late pregnancy. o Calcium is contraindicated to people with all conditions associated with hypercalcaemia and hypercalciuria o Selenium is not contra indicated to any specific group of individual STEP 4: Dose, Dosage and Course of Vitamins and Minerals (30minutes) • Vitamin A, in prevention of vitamin deficiency, child 1 month–5 years, 5 drops daily (5 drops contain vitamin A approx. 700 units, vitamin D approx. 300 units, ascorbic acid approx. 20 mg) until the condition subside • Vitamin B complex, is usually formulated as a tablet contains combination of nicotinamide 15 mg, riboflavin 1 mg, thiamine hydrochloride 1 mg. The dose is usually 1–2 tablets daily • Vitamin C is given prophylactically at the dose 25–75 mg daily; therapeutic, not less than 250 mg daily in divided doses • Vitamin D, is given as oral supplement of only 10 micrograms (400 units) of Ergocalciferol, calciferol, vitamin D2 or colecalciferol daily • Vitamin E it is given as a supplement at the dose of 3 to 5mg daily until the condition subsides • Vitamin K 10–40 mg daily, adjusted as necessary; child 1–12 years, 5–10 mg daily, adjusted as necessary, 12–18 years, 10–20 mg daily, adjusted as necessary PST 04211 Basic Pharmacology NTA Level 4 Semester 2 Facilitator Guide 284 • Calcium is presented as given orange flavored tablet of calcium carbonate at the dose of 2.5 g daily until the condition is corrected • Selenium is given by mouth or by intramuscular injection or by intravenous injection, 100–500 micrograms daily until the condition is corrected STEP 5: Side Effects and Adverse Effects of Vitamins and Minerals (20 Minute) Activity: Brainstorming (5 minutes) Ask students to brainstorm on the following question: • What are the side effects and adverse effects of Vitamins and Minerals ALLOW few students to respond WRITE their responses on the flip chart/ board CLARIFY and SUMMARISE
