Calcium Channel BlockerRx

Amlodipine

Generic: Amlodipine

Penicillin AntibioticRx

Amoxicillin

Generic: Amoxicillin

Treat bacterial infections

⚙️ Work Mechanism:

Amoxicillin destroys bacteria by sabotaging their ability to construct protective cell walls. As bacteria divide, their cell walls weaken and pop under fluid pressure, curing the bacterial infection.

Antibiotic (Penicillin + Beta-Lactamase Inhibitor)Prescription

Amoxicillin and Potassium Clavulanate

Generic: Amoxicillin Trihydrate and Potassium Clavulanate

Indicated for severe or recurrent acute otitis media, acute bacterial sinusitis, community-acquired pneumonia, acute exacerbations of chronic bronchitis, uncomplicated and complicated urinary tract infections (pyelonephritis, recurrent cystitis), skin and soft-tissue infections (cellulitis, animal bites, severe dental abscesses), and intra-abdominal or pelvic infections.

⚙️ Work Mechanism:

This medicine combines two active agents that work together as a powerful antibacterial team: Amoxicillin attacks and breaks down the bacterial cell wall, causing bacteria to rupture and die. Potassium Clavulanate acts as an enzyme shield, disarming the chemical weapons (beta-lactamase enzymes) that resistant bacteria produce to destroy antibiotics. By neutralizing bacterial resistance, the combination cures deep and persistent infections.

Salicylate, NSAIDOTC

Aspirin

Generic: Aspirin

Pain relief, prevent heart attacks

⚙️ Work Mechanism:

At low doses, Aspirin permanently deactivates the sticky chemical signals inside platelets, keeping blood flowing smoothly and preventing heart attacks and ischemic strokes.

Beta BlockerRx

Atenolol

Generic: Atenolol

Treat high blood pressure

⚙️ Work Mechanism:

Atenolol relaxes tight blood vessels and supports regular cardiac pumping, keeping blood pressure within a healthy range and protecting heart health.

StatinRx

Atorvastatin

Generic: Atorvastatin

Lower cholesterol

⚙️ Work Mechanism:

Atorvastatin shuts down the liver enzyme that manufactures bad LDL cholesterol, prompting the liver to clear existing cholesterol out of the bloodstream, preventing arterial plaques and cardiovascular events.

Macrolide AntibioticRx

Azithromycin

Generic: Azithromycin

Treat bacterial infections

⚙️ Work Mechanism:

Azithromycin stops bacteria from growing and multiplying by jamming their protein-building machinery. Without essential proteins, bacteria cannot survive.

Baclofen

Generic: Baclofen

Relieve muscle spasms

⚙️ Work Mechanism:

Baclofen works at the cellular level to correct underlying biochemical imbalances, reduce clinical symptoms, and support overall health.

ACE InhibitorRx

Benazepril

Generic: Benazepril

Treat high blood pressure

⚙️ Work Mechanism:

Benazepril relaxes tight blood vessels and supports regular cardiac pumping, keeping blood pressure within a healthy range and protecting heart health.

Beta-1 Selective BlockerRx

Bisoprolol

Generic: Bisoprolol

Treat high blood pressure

⚙️ Work Mechanism:

Bisoprolol relaxes tight blood vessels and supports regular cardiac pumping, keeping blood pressure within a healthy range and protecting heart health.

Budesonide

Generic: Budesonide

Control asthma or Crohn's

⚙️ Work Mechanism:

Budesonide works at the cellular level to correct underlying biochemical imbalances, reduce clinical symptoms, and support overall health.

Antibiotic (3rd Gen Cephalosporin)Prescription

Cefpodoxime Proxetil

Generic: Cefpodoxime Proxetil

Indicated for acute community-acquired pneumonia (CAP), acute bacterial exacerbations of chronic bronchitis (AECB), acute maxillary sinusitis, acute otitis media, streptococcal pharyngitis/tonsillitis, uncomplicated skin and soft tissue infections, and uncomplicated urinary tract infections (acute cystitis and uncomplicated gonococcal urethritis).

⚙️ Work Mechanism:

Cefpodoxime is a third-generation cephalosporin antibiotic that kills bacteria by preventing them from building their protective cell walls. By inactivating bacterial penicillin-binding proteins (PBPs), it causes the bacterial wall to crack, leak, and burst under internal osmotic pressure, rapidly clearing bacterial infections of the chest, throat, ears, sinuses, and urinary tract.

View Monograph & Dosage
Antibiotic (2nd Gen Cephalosporin)Prescription

Cefuroxime Axetil

Generic: Cefuroxime Axetil

Indicated for acute bacterial maxillary sinusitis, acute otitis media, pharyngitis/tonsillitis, acute bacterial exacerbations of chronic bronchitis, secondary bacterial infections of acute bronchitis, uncomplicated skin and skin-structure infections, uncomplicated urinary tract infections, and early Lyme disease (erythema migrans).

⚙️ Work Mechanism:

Cefuroxime is a second-generation antibiotic that destroys bacteria by breaking down their protective cell wall. It binds to essential bacterial enzymes (penicillin-binding proteins) that lock cell wall components together. Without this protective barrier, bacteria cannot survive and rupture, eradicating stubborn lung, sinus, ear, and Lyme disease infections.

COX-2 Inhibitor, NSAIDRx

Celecoxib

Generic: Celecoxib

Relieve pain and inflammation

⚙️ Work Mechanism:

Celecoxib calms inflammation and blocks chemical pain signals in the nervous system to deliver targeted relief from aches, fever, and stiffness.

Antibiotic (1st Gen Cephalosporin)Prescription

Cephalexin

Generic: Cephalexin (Cefalexin)

First-line therapy for skin and soft tissue infections (cellulitis, impetigo, folliculitis, furuncles, wound infections), streptococcal pharyngitis/tonsillitis, uncomplicated urinary tract infections (acute cystitis), acute otitis media, and bone infections (osteomyelitis) caused by susceptible organisms.

⚙️ Work Mechanism:

Cephalexin works by disabling the enzymes bacteria need to build and maintain their strong cellular outer walls. As the bacteria attempt to grow and divide without intact peptidoglycan mesh, their cell wall breaks down and bursts due to internal fluid pressure, killing the bacteria and curing the infection.

Cetirizine

Generic: Cetirizine Hydrochloride

Relief of symptoms associated with seasonal and perennial allergic rhinitis (sneezing, rhinorrhea, nasal itching, itchy watery eyes) and uncomplicated skin manifestations of chronic idiopathic urticaria (hives).

⚙️ Work Mechanism:

Cetirizine blocks histamine, the natural allergic substance released during pollen or dust exposure, relieving sneezing, runny nose, itchy eyes, and hives without causing heavy drowsiness.
