5.1 Conclusion
Taken together our findings indicate that the co-administration of Metformin and Amlodipine in Wistar Rats had a serious effect on Red cell parameters with little or no effect on the red cell indices. In view of the present study, it can be concluded that co-administration of metformin and amlodipine have a detrimental effect on the hematological parameters (red cell indices) which unraveled its anaemia induced effect.
5.2 Recommendation
1. From the present study, co-administration of metformin and amilodipine has the ability to induce anaemia after a long-term usage. Hence the need for more human study to be made on patient to study the effect of long-term usage of both drugs in patients with diabetics as well as hypertension.
2. Further study should be carried out to investigate the effect of co-administration of metformin and amilodipine on the biochemical parameters in Wistar Rats so as to unvail its mechanism of action (haemolytic anaemia from Bilirubin increase).
3. Further study should also be carried to investigate the effect of co-administration of metformin and amilodipine on serum erythropoietin levels in Wistar Rats.
4. Further study should also be carried to investigate the effect of co-administration of metformin and amilodipine on serum Vitamin B12 levels in Wistar Rats since research indicate that’s the mechanism of action.
5. The effect of co-administration of metformin and amilodipine on Wistar Rats have been investigated hence the need studies in other experimental model.

ABSRACT - [ Total Page(s): 1 ]ABSTRACTMetformin, which belongs to the biguanide class, is one of the most generally used oral hypoglycemic agents. It has been used for more than 50 years and was approved by the US Food and Drug Administration (FDA) in 1994 (American Diabetes Association, 2009) whereas Amlodipine is a long acting dihydropyridine calcium channel blocker, which is used in the treatment of angina to lower the BP (Blood pressure). the aim is to know the effect of co-administration of this two drugs in Wistar rats ...

CHAPTER TWO - [ Total Page(s): 12 ]The current use of serum Vitamin B12 level relies on several different range points for Vitamin B12 status. Serum Vitamin B12 level under 148 pmol/L are said to be deficient, low/borderline levels are interpreted from levels between 148-220 pmol/L (Mazokopakis and Starakis, 2012). Normal ranges of Vitamin B12 serum range from 220- 800 pmol/L, levels that exceed this are rarely suspicious in cause, although excessive B12 serum may be a marker of myloproliferative disorders (Pernicova and Korbonit ...

Although, decrease in RBC counts was observed in the treated (co-administration of metformin and amlodipine) dose group, these were statistically significant compared to control groups (student t test P0.05) higher in the tr ...
