Clinical Summary

A selective adrenergic beta-1 blocking agent that is commonly used to treat ANGINA PECTORIS; HYPERTENSION; and CARDIAC ARRHYTHMIAS.

Therapeutic Applications

This medication is a beta-blocker used to treat chest pain (angina), heart failure, and high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This drug works by blocking the action of certain natural chemicals in your body (such as epinephrine) that affect the heart and blood vessels. This lowers heart rate, blood pressure, and strain on the heart.

Clinical Summary

Insulin that has been modified to contain an ASPARTIC ACID instead of a PROLINE at position 38 of the B-chain.

Therapeutic Applications

Insulin aspart is used with a proper diet and exercise program to control high blood sugar in people with diabetes. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes may also lessen your risk of a heart attack or stroke. Insulin aspart is a man-made product that is similar to human insulin. It replaces the insulin that your body would normally make. Insulin aspart starts working faster and lasts for a shorter time than regular insulin. It works by helping blood sugar (glucose) get into cells so your body can use it for energy. This medication is usually used with a medium- or long-acting insulin product.

Therapeutic Applications

Semaglutide is used with a proper diet and exercise program to control high blood sugar in people with type 2 diabetes. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Semaglutide is also used in people with type 2 diabetes and heart disease to lower the risk of death from heart attack or stroke. Semaglutide is similar to a natural hormone in your body (incretin). It works by causing insulin release in response to high blood sugar (such as after a meal) and decreasing the amount of sugar your liver makes. If you use insulin, semaglutide is not a substitute for insulin treatment.

It works by helping to restore your body's proper response to insulin, thereby lowering your blood sugar. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes may also lessen your risk of a heart attack or stroke. Pioglitazone is used either alone or in combination with other diabetes medications (such as metformin or a sulfonylurea such as glyburide). Talk to your doctor about the risks and benefits of pioglitazone.

Clinical Summary

A HYDROXYMETHYLGLUTARYL-COA-REDUCTASE INHIBITOR, or statin, that reduces the plasma concentrations of LDL-CHOLESTEROL; APOLIPOPROTEIN B, and TRIGLYCERIDES while increasing HDL-CHOLESTEROL levels in patients with HYPERCHOLESTEROLEMIA and those at risk for CARDIOVASCULAR DISEASES.

Therapeutic Applications

Rosuvastatin is used along with a proper diet to help lower bad cholesterol and fats (such as LDL, triglycerides) and raise good cholesterol (HDL) in the blood. It belongs to a group of drugs known as statins. It works by reducing the amount of cholesterol made by the liver. Lowering bad cholesterol and triglycerides and raising good cholesterol decreases the risk of heart disease and helps to prevent strokes and heart attacks. In addition to eating a proper diet (such as a low cholesterol/low-fat diet), other lifestyle changes that may help this medication work better include exercising, losing weight if overweight, and stopping smoking. Talk with your doctor for more details.

Clinical Summary

A potassium sparing diuretic that acts by antagonism of aldosterone in the distal renal tubules. It is used mainly in the treatment of refractory edema in patients with congestive heart failure, nephrotic syndrome, or hepatic cirrhosis. Its effects on the endocrine system are utilized in the treatments of hirsutism and acne but they can lead to adverse effects. (From Martindale, The Extra Pharmacopoeia, 30th ed, p827)

Therapeutic Applications

Spironolactone is used to treat high blood pressure and heart failure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. It is also used to treat swelling (edema) caused by certain conditions (such as heart failure, liver disease) by removing excess fluid and improving symptoms such as breathing problems. This medication is also used to treat conditions in which the body is making too much of a natural substance (aldosterone). Spironolactone is known as a water pill (potassium-sparing diuretic).

Dataset Methodology & CMS Source Information

This analytical profile maps public infrastructure records sourced directly from official **Centers for Medicare & Medicaid Services (CMS)** public data releases. The statistics above track documented pharmaceutical treatment trends assigned to beneficiaries specifically under federal public programs. Evaluating the prescriptive footprints of clinical practitioners like MR. LOK SHUN (LENNY) CHAN PHARMD provides transparency into local medical care patterns within San Francisco, CA.

Key Learning Objectives for this Profile:

  • Prescribing Frequencies: Track and evaluate the volume metrics of specific brand-name and generic medical formulas chosen by this provider over time.
  • Clinical Focus Areas: Identify how the provider distributes therapeutic selections across medical care options to gain insight into their true day-to-day **Pharmacotherapy** practice concentrations.
  • Program Cost Awareness: Review the calculated total systemic drug costs and raw transactional volumes linked to these orders to better anticipate network insurance coverage structures.
  • Patient-Centered Evaluation: Cross-reference localized regional care comparisons to align practitioner habits directly with your proactive health maintenance goals.

Data Scope Exclusion & Limitations: The data elements presented above explicitly reflect prescription orders processed for Medicare beneficiaries during the year 2023. This informational profile does not aggregate prescription data for individuals utilizing private commercial health plans, state Medicaid coverage, or self-pay options. However, because medical decision-making remains highly consistent across clinical settings, this public registry provides a reliable proxy for understanding the general prescribing preferences and pharmaceutical care approach used by this provider.
